The embodiments described herein relate generally to a method and apparatus for improving the capabilities of security systems in home and business applications. More particularly, the embodiments described herein relate to a touchscreen device that integrates security system control and functionality with network content interactivity, management and presentation.
The field of home and small business security is dominated by technology suppliers who build comprehensive ‘closed’ security systems, where the individual components (sensors, security panels, keypads) operate solely within the confines of a single vendor solution. For example, a wireless motion sensor from vendor A cannot be used with a security panel from vendor B. Each vendor typically has developed sophisticated proprietary wireless technologies to enable the installation and management of wireless sensors, with little or no ability for the wireless devices to operate separate from the vendor's homogeneous system. Furthermore, these traditional systems are extremely limited in their ability to interface either to a local or wide area standards-based network (such as an IP network); most installed systems support only a low-bandwidth, intermittent connection utilizing phone lines or cellular (RF) backup systems. Wireless security technology from providers such as GE Security, Honeywell, and DSC/Tyco are well known in the art, and are examples of this proprietary approach to security systems for home and business.
Furthermore, with the proliferation of the internet, ethernet and WiFi local area networks (LANs) and advanced wide area networks (WANs) that offer high bandwidth, low latency connections (broadband), as well as more advanced wireless WAN data networks (e.g. GPRS or CDMA 1×RTT) there increasingly exists the networking capability to extend these traditional security systems to offer enhanced functionality. In addition, the proliferation of broadband access has driven a corresponding increase in home and small business networking technologies and devices. It is desirable to extend traditional security systems to encompass enhanced functionality such as the ability to control and manage security systems from the world wide web, cellular telephones, or advanced function internet-based devices. Other desired functionality includes an open systems approach to interface home security systems to home and small business networks.
Due to the proprietary approach described above, the traditional vendors are the only ones capable of taking advantage of these new network functions. To date, even though the vast majority of home and business customers have broadband network access in their premises, most security systems do not offer the advanced capabilities associated with high speed, low-latency LANs and WANs. This is primarily because the proprietary vendors have not been able to deliver such technology efficiently or effectively. Solution providers attempting to address this need are becoming known in the art, including three categories of vendors: traditional proprietary hardware providers such as Honeywell and GE Security; third party hard-wired module providers such as Alarm.com, NextAlarm, and uControl; and new proprietary systems providers such as InGrid.
A disadvantage of the prior art technologies of the traditional proprietary hardware providers arises due to the continued proprietary approach of these vendors. As they develop technology in this area it once again operates only with the hardware from that specific vendor, ignoring the need for a heterogeneous, cross-vendor solution. Yet another disadvantage of the prior art technologies of the traditional proprietary hardware providers arises due to the lack of experience and capability of these companies in creating open internet and web based solutions, and consumer friendly interfaces.
A disadvantage of the prior art technologies of the third party hard-wired module providers arises due to the installation and operational complexities and functional limitations associated with hardwiring a new component into existing security systems. Moreover, a disadvantage of the prior art technologies of the new proprietary systems providers arises due to the need to discard all prior technologies, and implement an entirely new form of security system to access the new functionalities associated with broadband and wireless data networks. There remains, therefore, a need for systems, devices, and methods that easily interface to and control the existing proprietary security technologies utilizing a variety of wireless technologies.
Each patent, patent application, and/or publication mentioned in this specification is herein incorporated by reference in its entirety to the same extent as if each individual patent, patent application, and/or publication was specifically and individually indicated to be incorporated by reference.
An integrated security system is described that integrates broadband and mobile access and control with conventional security systems and premise devices to provide a tri-mode security network (broadband, cellular/GSM, POTS access) that enables users to remotely stay connected to their premises. The integrated security system, while delivering remote premise monitoring and control functionality to conventional monitored premise protection, complements existing premise protection equipment. The integrated security system integrates into the premise network and couples wirelessly with the conventional security panel, enabling broadband access to premise security systems. Automation devices (cameras, lamp modules, thermostats, etc.) can be added, enabling users to remotely see live video and/or pictures and control home devices via their personal web portal or webpage, mobile phone, and/or other remote client device. Users can also receive notifications via email or text message when happenings occur, or do not occur, in their home.

The teachings of the integrated security system and corresponding systems and methods provided herein can be applied to other systems and methods, not only for the systems and methods described above.
The elements and acts of the various embodiments described above can be combined to provide further embodiments. These and other changes can be made to the integrated security system and corresponding systems and methods in light of the above detailed description.
In accordance with the embodiments described herein, a wireless system (e.g., radio frequency (RF)) is provided that enables a security provider or consumer to extend the capabilities of an existing RF-capable security system or a non-RF-capable security system that has been upgraded to support RF capabilities. The system includes an RF-capable Gateway device (physically located within RF range of the RF-capable security system) and associated software operating on the Gateway device. The system also includes a web server, application server, and remote database providing a persistent store for information related to the system.
The security systems of an embodiment, referred to herein as the iControl security system or integrated security system, extend the value of traditional home security by adding broadband access and the advantages of remote home monitoring and home control through the formation of a security network including components of the integrated security system integrated with a conventional premise security system and a premise local area network (LAN). With the integrated security system, conventional home security sensors, cameras, touchscreen keypads, lighting controls, and/or Internet Protocol (IP) devices in the home (or business) become connected devices that are accessible anywhere in the world from a web browser, mobile phone or through content-enabled touchscreens. The integrated security system experience allows security operators to both extend the value proposition of their monitored security systems and reach new consumers that include broadband users interested in staying connected to their family, home and property when they are away from home.
The integrated security system of an embodiment includes security servers (also referred to herein as iConnect servers or security network servers) and an iHub gateway (also referred to herein as the gateway, the iHub, or the iHub client) that couples or integrates into a home network (e.g., LAN) and communicates directly with the home security panel, in both wired and wireless installations. The security system of an embodiment automatically discovers the security system components (e.g., sensors, etc.) belonging to the security system and connected to a control panel of the security system and provides consumers with full two-way access via web and mobile portals. The gateway supports various wireless protocols and can interconnect with a wide range of control panels offered by security system providers. Service providers and users can then extend the system's capabilities with the additional IP cameras, lighting modules or security devices such as interactive touchscreen keypads. The integrated security system adds an enhanced value to these security systems by enabling consumers to stay connected through email and SMS alerts, photo push, event-based video capture and rule-based monitoring and notifications. This solution extends the reach of home security to households with broadband access.
The integrated security system builds upon the foundation afforded by traditional security systems by layering broadband and mobile access, IP cameras, interactive touchscreens, and an open approach to home automation on top of traditional security system configurations. The integrated security system is easily installed and managed by the security operator, and simplifies the traditional security installation process, as described below.
The integrated security system provides an open systems solution to the home security market. As such, the foundation of the integrated security system customer premises equipment (CPE) approach has been to abstract devices, and allows applications to manipulate and manage multiple devices from any vendor. The integrated security system DeviceConnect technology that enables this capability supports protocols, devices, and panels from GE Security and Honeywell, as well as consumer devices using Z-Wave, IP cameras (e.g., Ethernet, wife, and Homeplug), and IP touchscreens. The DeviceConnect is a device abstraction layer that enables any device or protocol layer to interoperate with integrated security system components. This architecture enables the addition of new devices supporting any of these interfaces, as well as add entirely new protocols.
The benefit of DeviceConnect is that it provides supplier flexibility. The same consistent touchscreen, web, and mobile user experience operate unchanged on whatever security equipment selected by a security system provider, with the system provider's choice of IP cameras, backend data center and central station software.
The integrated security system provides a complete system that integrates or layers on top of a conventional host security system available from a security system provider. The security system provider therefore can select different components or configurations to offer (e.g., CDMA, GPRS, no cellular, etc.) as well as have iControl modify the integrated security system configuration for the system provider's specific needs (e.g., change the functionality of the web or mobile portal, add a GE or Honeywell-compatible TouchScreen, etc.).
The integrated security system integrates with the security system provider infrastructure for central station reporting directly via Broadband and GPRS alarm transmissions. Traditional dial-up reporting is supported via the standard panel connectivity. Additionally, the integrated security system provides interfaces for advanced functionality to the CMS, including enhanced alarm events, system installation optimizations, system test verification, video verification, 2-way voice over IP and GSM.
The integrated security system is an IP centric system that includes broadband connectivity so that the gateway augments the existing security system with broadband and GPRS connectivity. If broadband is down or unavailable GPRS may be used, for example. The integrated security system supports GPRS connectivity using an optional wireless package that includes a GPRS modem in the gateway. The integrated security system treats the GPRS connection as a higher cost though flexible option for data transfers. In an embodiment the GPRS connection is only used to route alarm events (e.g., for cost), however the gateway can be configured (e.g., through the iConnect server interface) to act as a primary channel and pass any or all events over GPRS. Consequently, the integrated security system does not interfere with the current plain old telephone service (POTS) security panel interface. Alarm events can still be routed through POTS; however the gateway also allows such events to be routed through a broadband or GPRS connection as well. The integrated security system provides a web application interface to the CSR tool suite as well as XML web services interfaces for programmatic integration between the security system provider's existing call center products. The integrated security system includes, for example, APIs that allow the security system provider to integrate components of the integrated security system into a custom call center interface. The APIs include XML web service APIs for integration of existing security system provider call center applications with the integrated security system service. All functionality available in the CSR Web application is provided with these API sets. The Java and XML-based APIs of the integrated security system support provisioning, billing, system administration, CSR, central station, portal user interfaces, and content management functions, to name a few. The integrated security system can provide a customized interface to the security system provider's billing system, or alternatively can provide security system developers with APIs and support in the integration effort.
The integrated security system provides or includes business component interfaces for provisioning, administration, and customer care to name a few. Standard templates and examples are provided with a defined customer professional services engagement to help integrate OSS/BSS systems of a Service Provider with the integrated security system.
The integrated security system components support and allow for the integration of customer account creation and deletion with a security system. The iConnect APIs provides access to the provisioning and account management system in iConnect and provide full support for account creation, provisioning, and deletion. Depending on the requirements of the security system provider, the iConnect APIs can be used to completely customize any aspect of the integrated security system backend operational system.
The integrated security system includes a gateway that supports the following standards-based interfaces, to name a few: Ethernet IP communications via Ethernet ports on the gateway, and standard XML/TCP/IP protocols and ports are employed over secured SSL sessions; USB 2.0 via ports on the gateway; 802.11b/g/n IP communications; GSM/GPRS RF WAN communications; CDMA 1×RTT RF WAN communications (optional, can also support EVDO and 3G technologies).
The gateway supports the following proprietary interfaces, to name a few: interfaces including Dialog RF network (319.5 MHz) and RS485 Superbus 2000 wired interface; RF mesh network (908 MHz); and interfaces including RF network (345 MHz) and RS485/RS232bus wired interfaces.
Regarding security for the IP communications (e.g., authentication, authorization, encryption, anti-spoofing, etc), the integrated security system uses SSL to encrypt all IP traffic, using server and client-certificates for authentication, as well as authentication in the data sent over the SSL-encrypted channel. For encryption, integrated security system issues public/private key pairs at the time/place of manufacture, and certificates are not stored in any online storage in an embodiment.
The integrated security system does not need any special rules at the customer premise and/or at the security system provider central station because the integrated security system makes outgoing connections using TCP over the standard HTTP and HTTPS ports. Provided outbound TCP connections are allowed then no special requirements on the firewalls are necessary.
The integrated security system service (also referred to as iControl service) can be managed by a service provider via browser-based Maintenance and Service Management applications that are provided with the iConnect Servers. Or, if desired, the service can be more tightly integrated with existing OSS/BSS and service delivery systems via the iConnect web services-based XML APIs.
The integrated security system service can also coordinate the sending of alarms to the home security Central Monitoring Station (CMS) 199. Alarms are passed to the CMS 199 using standard protocols such as Contact ID or SIA and can be generated from the home security panel location as well as by iConnect server 104 conditions (such as lack of communications with the integrated security system). In addition, the link between the security servers 104 and CMS 199 provides tighter integration between home security and self-monitoring devices and the gateway 102. Such integration enables advanced security capabilities such as the ability for CMS personnel to view photos taken at the time a burglary alarm was triggered. For maximum security, the gateway 102 and iConnect servers 104 support the use of a mobile network (both GPRS and CDMA options are available) as a backup to the primary broadband connection.
The integrated security system service is delivered by hosted servers running software components that communicate with a variety of client types while interacting with other systems.
The iConnect servers 104 support a diverse collection of clients 120 ranging from mobile devices, to PCs, to in-home security devices, to a service provider's internal systems. Most clients 120 are used by end-users, but there are also a number of clients 120 that are used to operate the service.
Clients 120 used by end-users of the integrated security system 100 include, but are not limited to, the following:
In addition to the end-user clients, the iConnect servers 104 support PC browser-based Service Management clients that manage the ongoing operation of the overall service. These clients run applications that handle tasks such as provisioning, service monitoring, customer support and reporting.
There are numerous types of server components of the iConnect servers 104 of an embodiment including, but not limited to, the following: Business Components which manage information about all of the home security and self-monitoring devices; End-User Application Components which display that information for users and access the Business Components via published XML APIs; and Service Management Application Components which enable operators to administer the service (these components also access the Business Components via the XML APIs, and also via published SNMP MIBs).
The server components provide access to, and management of, the objects associated with an integrated security system installation. The top-level object is the “network.” It is a location where a gateway 102 is located, and is also commonly referred to as a site or premises; the premises can include any type of structure (e.g., home, office, warehouse, etc.) at which a gateway 102 is located. Users can only access the networks to which they have been granted permission. Within a network, every object monitored by the gateway 102 is called a device. Devices include the sensors, cameras, home security panels and automation devices, as well as the controller or processor-based device running the gateway applications.
Various types of interactions are possible between the objects in a system. Automations define actions that occur as a result of a change in state of a device. For example, take a picture with the front entry camera when the front door sensor changes to “open”. Notifications are messages sent to users to indicate that something has occurred, such as the front door going to “open” state, or has not occurred (referred to as an iWatch notification). Schedules define changes in device states that are to take place at predefined days and times. For example, set the security panel to “Armed” mode every weeknight at 11:00 pm.
The iConnect Business Components are responsible for orchestrating all of the low-level service management activities for the integrated security system service. They define all of the users and devices associated with a network (site), analyze how the devices interact, and trigger associated actions (such as sending notifications to users). All changes in device states are monitored and logged. The Business Components also manage all interactions with external systems as required, including sending alarms and other related self-monitoring data to the home security Central Monitoring System (CMS) 199. The Business Components are implemented as portable Java J2EE Servlets, but are not so limited.
The following iConnect Business Components manage the main elements of the integrated security system service, but the embodiment is not so limited:
Additional iConnect Business Components handle direct communications with certain clients and other systems, for example:
The iControl Business Components provide web services-based APIs that application components use to access the Business Components' capabilities. Functions of application components include presenting integrated security system service data to end-users, performing administrative duties, and integrating with external systems and back-office applications.
The primary published APIs for the iConnect Business Components include, but are not limited to, the following:
Each API of an embodiment includes two modes of access: Java API or XML API. The XML APIs are published as web services so that they can be easily accessed by applications or servers over a network. The Java APIs are a programmer-friendly wrapper for the XML APIs. Application components and integrations written in Java should generally use the Java APIs rather than the XML APIs directly.
The iConnect Business Components also have an XML-based interface 260 for quickly adding support for new devices to the integrated security system. This interface 260, referred to as DeviceConnect 260, is a flexible, standards-based mechanism for defining the properties of new devices and how they can be managed. Although the format is flexible enough to allow the addition of any type of future device, pre-defined XML profiles are currently available for adding common types of devices such as sensors (SensorConnect), home security panels (PanelConnect) and IP cameras (CameraConnect).
The iConnect End-User Application Components deliver the user interfaces that run on the different types of clients supported by the integrated security system service. The components are written in portable Java J2EE technology (e.g., as Java Servlets, as JavaServer Pages (JSPs), etc.) and they all interact with the iControl Business Components via the published APIs.
The following End-User Application Components generate CS S-based HTML/JavaScript that is displayed on the target client. These applications can be dynamically branded with partner-specific logos and URL links (such as Customer Support, etc.). The End-User Application Components of an embodiment include, but are not limited to, the following:
A number of Application Components are responsible for overall management of the service. These pre-defined applications, referred to as Service Management Application Components, are configured to offer off-the-shelf solutions for production management of the integrated security system service including provisioning, overall service monitoring, customer support, and reporting, for example. The Service Management Application Components of an embodiment include, but are not limited to, the following:
The iConnect servers 104 also support custom-built integrations with a service provider's existing OSS/BSS, CSR and service delivery systems 290. Such systems can access the iConnect web services XML API to transfer data to and from the iConnect servers 104. These types of integrations can compliment or replace the PC browser-based Service Management applications, depending on service provider needs.
As described above, the integrated security system of an embodiment includes a gateway, or iHub. The gateway of an embodiment includes a device that is deployed in the home or business and couples or connects the various third-party cameras, home security panels, sensors and devices to the iConnect server over a WAN connection as described in detail herein. The gateway couples to the home network and communicates directly with the home security panel in both wired and wireless sensor installations. The gateway is configured to be low-cost, reliable and thin so that it complements the integrated security system network-based architecture.
The gateway supports various wireless protocols and can interconnect with a wide range of home security control panels. Service providers and users can then extend the system's capabilities by adding IP cameras, lighting modules and additional security devices. The gateway is configurable to be integrated into many consumer appliances, including set-top boxes, routers and security panels. The small and efficient footprint of the gateway enables this portability and versatility, thereby simplifying and reducing the overall cost of the deployment.
The gateway application layer 302 is the main program that orchestrates the operations performed by the gateway. The Security Engine 304 provides robust protection against intentional and unintentional intrusion into the integrated security system network from the outside world (both from inside the premises as well as from the WAN). The Security Engine 304 of an embodiment comprises one or more sub-modules or components that perform functions including, but not limited to, the following:
As standards evolve, and new encryption and authentication methods are proven to be useful, and older mechanisms proven to be breakable, the security manager can be upgraded “over the air” to provide new and better security for communications between the iConnect server and the gateway application, and locally at the premises to remove any risk of eavesdropping on camera communications.
A Remote Firmware Download module 306 allows for seamless and secure updates to the gateway firmware through the iControl Maintenance Application on the server 104, providing a transparent, hassle-free mechanism for the service provider to deploy new features and bug fixes to the installed user base. The firmware download mechanism is tolerant of connection loss, power interruption and user interventions (both intentional and unintentional). Such robustness reduces down time and customer support issues. Gateway firmware can be remotely download either for one gateway at a time, a group of gateways, or in batches.
The Automations engine 308 manages the user-defined rules of interaction between the different devices (e.g. when door opens turn on the light). Though the automation rules are programmed and reside at the portal/server level, they are cached at the gateway level in order to provide short latency between device triggers and actions.
DeviceConnect 310 includes definitions of all supported devices (e.g., cameras, security panels, sensors, etc.) using a standardized plug-in architecture. The DeviceConnect module 310 offers an interface that can be used to quickly add support for any new device as well as enabling interoperability between devices that use different technologies/protocols. For common device types, pre-defined sub-modules have been defined, making supporting new devices of these types even easier. SensorConnect 312 is provided for adding new sensors, CameraConnect 316 for adding IP cameras, and PanelConnect 314 for adding home security panels.
The Schedules engine 318 is responsible for executing the user defined schedules (e.g., take a picture every five minutes; every day at 8 am set temperature to 65 degrees Fahrenheit, etc.). Though the schedules are programmed and reside at the iConnect server level they are sent to the scheduler within the gateway application. The Schedules Engine 318 then interfaces with SensorConnect 312 to ensure that scheduled events occur at precisely the desired time.
The Device Management module 320 is in charge of all discovery, installation and configuration of both wired and wireless IP devices (e.g., cameras, etc.) coupled or connected to the system. Networked IP devices, such as those used in the integrated security system, require user configuration of many IP and security parameters—to simplify the user experience and reduce the customer support burden, the device management module of an embodiment handles the details of this configuration. The device management module also manages the video routing module described below.
The video routing engine 322 is responsible for delivering seamless video streams to the user with zero-configuration. Through a multi-step, staged approach the video routing engine uses a combination of UPnP port-forwarding, relay server routing and STUN/TURN peer-to-peer routing.
Referring to the WAN portion 410 of the gateway 102, the gateway 102 of an embodiment can communicate with the iConnect server using a number of communication types and/or protocols, for example Broadband 412, GPRS 414 and/or Public Switched Telephone Network (PTSN) 416 to name a few. In general, broadband communication 412 is the primary means of connection between the gateway 102 and the iConnect server 104 and the GPRS/CDMA 414 and/or PSTN 416 interfaces acts as back-up for fault tolerance in case the user's broadband connection fails for whatever reason, but the embodiment is not so limited.
Referring to the LAN portion 420 of the gateway 102, various protocols and physical transceivers can be used to communicate to off-the-shelf sensors and cameras. The gateway 102 is protocol-agnostic and technology-agnostic and as such can easily support almost any device networking protocol. The gateway 102 can, for example, support GE and Honeywell security RF protocols 422, Z-Wave 424, serial (RS232 and RS485) 426 for direct connection to security panels as well as WiFi 428 (802.11b/g) for communication to WiFi cameras.
The integrated security system includes couplings or connections among a variety of IP devices or components, and the device management module is in charge of the discovery, installation and configuration of the IP devices coupled or connected to the system, as described above. The integrated security system of an embodiment uses a “sandbox” network to discover and manage all IP devices coupled or connected as components of the system. The IP devices of an embodiment include wired devices, wireless devices, cameras, interactive touchscreens, and security panels to name a few. These devices can be wired via ethernet cable or Wifi devices, all of which are secured within the sandbox network, as described below. The “sandbox” network is described in detail below.
The examples described above with reference to
The integrated security system of an embodiment includes a touchscreen (also referred to as the iControl touchscreen or integrated security system touchscreen), as described above, which provides core security keypad functionality, content management and presentation, and embedded systems design. The networked security touchscreen system of an embodiment enables a consumer or security provider to easily and automatically install, configure and manage the security system and touchscreen located at a customer premise. Using this system the customer may access and control the local security system, local IP devices such as cameras, local sensors and control devices (such as lighting controls or pipe freeze sensors), as well as the local security system panel and associated security sensors (such as door/window, motion, and smoke detectors). The customer premise may be a home, business, and/or other location equipped with a wired or wireless broadband IP connection.
The system of an embodiment includes a touchscreen with a configurable software user interface and/or a gateway device (e.g., iHub) that couples or connects to a premise security panel through a wired or wireless connection, and a remote server that provides access to content and information from the premises devices to a user when they are remote from the home. The touchscreen supports broadband and/or WAN wireless connectivity. In this embodiment, the touchscreen incorporates an IP broadband connection (e.g., Wifi radio, Ethernet port, etc.), and/or a cellular radio (e.g., GPRS/GSM, CDMA, WiMax, etc.). The touchscreen described herein can be used as one or more of a security system interface panel and a network user interface (UI) that provides an interface to interact with a network (e.g., LAN, WAN, internet, etc.).
The touchscreen of an embodiment provides an integrated touchscreen and security panel as an all-in-one device. Once integrated using the touchscreen, the touchscreen and a security panel of a premise security system become physically co-located in one device, and the functionality of both may even be co-resident on the same CPU and memory (though this is not required).
The touchscreen of an embodiment also provides an integrated IP video and touchscreen UI. As such, the touchscreen supports one or more standard video CODECs/players (e.g., H.264, Flash Video, MOV, MPEG4, M-JPEG, etc.). The touchscreen UI then provides a mechanism (such as a camera or video widget) to play video. In an embodiment the video is streamed live from an IP video camera. In other embodiments the video comprises video clips or photos sent from an IP camera or from a remote location.
The touchscreen of an embodiment provides a configurable user interface system that includes a configuration supporting use as a security touchscreen. In this embodiment, the touchscreen utilizes a modular user interface that allows components to be modified easily by a service provider, an installer, or even the end user. Examples of such a modular approach include using Flash widgets, HTML-based widgets, or other downloadable code modules such that the user interface of the touchscreen can be updated and modified while the application is running. In an embodiment the touchscreen user interface modules can be downloaded over the internet. For example, a new security configuration widget can be downloaded from a standard web server, and the touchscreen then loads such configuration app into memory, and inserts it in place of the old security configuration widget. The touchscreen of an embodiment is configured to provide a self-install user interface.
Embodiments of the networked security touchscreen system described herein include a touchscreen device with a user interface that includes a security toolbar providing one or more functions including arm, disarm, panic, medic, and alert. The touchscreen therefore includes at least one screen having a separate region of the screen dedicated to a security toolbar. The security toolbar of an embodiment is present in the dedicated region at all times that the screen is active.
The touchscreen of an embodiment includes a home screen having a separate region of the screen allocated to managing home-based functions. The home-based functions of an embodiment include managing, viewing, and/or controlling IP video cameras. In this embodiment, regions of the home screen are allocated in the form of widget icons; these widget icons (e.g. for cameras, thermostats, lighting, etc) provide functionality for managing home systems. So, for example, a displayed camera icon, when selected, launches a Camera Widget, and the Camera widget in turn provides access to video from one or more cameras, as well as providing the user with relevant camera controls (take a picture, focus the camera, etc.)
The touchscreen of an embodiment includes a home screen having a separate region of the screen allocated to managing, viewing, and/or controlling internet-based content or applications. For example, the Widget Manager UI presents a region of the home screen (up to and including the entire home screen) where internet widgets icons such as weather, sports, etc. may be accessed). Each of these icons may be selected to launch their respective content services.
The touchscreen of an embodiment is integrated into a premise network using the gateway, as described above. The gateway as described herein functions to enable a separate wireless network, or sub-network, that is coupled, connected, or integrated with another network (e.g., WAN, LAN of the host premises, etc.). The sub-network enabled by the gateway optimizes the installation process for IP devices, like the touchscreen, that couple or connect to the sub-network by segregating these IP devices from other such devices on the network. This segregation of the IP devices of the sub-network further enables separate security and privacy policies to be implemented for these IP devices so that, where the IP devices are dedicated to specific functions (e.g., security), the security and privacy policies can be tailored specifically for the specific functions. Furthermore, the gateway and the sub-network it forms enables the segregation of data traffic, resulting in faster and more efficient data flow between components of the host network, components of the sub-network, and between components of the sub-network and components of the network.
The touchscreen of an embodiment includes a core functional embedded system that includes an embedded operating system, required hardware drivers, and an open system interface to name a few. The core functional embedded system can be provided by or as a component of a conventional security system (e.g., security system available from GE Security). These core functional units are used with components of the integrated security system as described herein. Note that portions of the touchscreen description below may include reference to a host premise security system (e.g., GE security system), but these references are included only as an example and do not limit the touchscreen to integration with any particular security system.
As an example, regarding the core functional embedded system, a reduced memory footprint version of embedded Linux forms the core operating system in an embodiment, and provides basic TCP/IP stack and memory management functions, along with a basic set of low-level graphics primitives. A set of device drivers is also provided or included that offer low-level hardware and network interfaces. In addition to the standard drivers, an interface to the RS 485 bus is included that couples or connects to the security system panel (e.g., GE Concord panel). The interface may, for example, implement the Superbus 2000 protocol, which can then be utilized by the more comprehensive transaction-level security functions implemented in PanelConnect technology (e.g SetAlarmLevel (int level, int partition, char *accessCode)). Power control drivers are also provided.
More specifically, the touchscreen, when configured as a home security device, includes but is not limited to the following application or software modules: RS 485 and/or RS-232 bus security protocols to conventional home security system panel (e.g., GE Concord panel); functional home security classes and interfaces (e.g. Panel ARM state, Sensor status, etc.); Application/Presentation layer or engine; Resident Application; Consumer Home Security Application; installer home security application; core engine; and System bootloader/Software Updater. The core Application engine and system bootloader can also be used to support other advanced content and applications. This provides a seamless interaction between the premise security application and other optional services such as weather widgets or IP cameras.
An alternative configuration of the touchscreen includes a first Application engine for premise security and a second Application engine for all other applications. The integrated security system application engine supports content standards such as HTML, XML, Flash, etc. and enables a rich consumer experience for all ‘widgets’, whether security-based or not. The touchscreen thus provides service providers the ability to use web content creation and management tools to build and download any ‘widgets’ regardless of their functionality.
As discussed above, although the Security Applications have specific low-level functional requirements in order to interface with the premise security system, these applications make use of the same fundamental application facilities as any other ‘widget’, application facilities that include graphical layout, interactivity, application handoff, screen management, and network interfaces, to name a few.
Content management in the touchscreen provides the ability to leverage conventional web development tools, performance optimized for an embedded system, service provider control of accessible content, content reliability in a consumer device, and consistency between ‘widgets’ and seamless widget operational environment. In an embodiment of the integrated security system, widgets are created by web developers and hosted on the integrated security system Content Manager (and stored in the Content Store database). In this embodiment the server component caches the widgets and offers them to consumers through the web-based integrated security system provisioning system. The servers interact with the advanced touchscreen using HTTPS interfaces controlled by the core engine and dynamically download widgets and updates as needed to be cached on the touchscreen. In other embodiments widgets can be accessed directly over a network such as the Internet without needing to go through the iControl Content Manager
Referring to
The application engine of the touchscreen provides the presentation and interactivity capabilities for all applications (widgets) that run on the touchscreen, including both core security function widgets and third party content widgets.
A component of the application engine is the Presentation Engine, which includes a set of libraries that implement the standards-based widget content (e.g., XML, HTML, JavaScript, Flash) layout and interactivity. This engine provides the widget with interfaces to dynamically load both graphics and application logic from third parties, support high level data description language as well as standard graphic formats. The set of web content-based functionality available to a widget developer is extended by specific touchscreen functions implemented as local web services by the Core Engine.
The resident application of the touchscreen is the master service that controls the interaction of all widgets in the system, and enforces the business and security rules required by the service provider. For example, the resident application determines the priority of widgets, thereby enabling a home security widget to override resource requests from a less critical widget (e.g. a weather widget). The resident application also monitors widget behavior, and responds to client or server requests for cache updates.
The core engine of the touchscreen manages interaction with other components of the integrated security system, and provides an interface through which the resident application and authorized widgets can get information about the home security system, set alarms, install sensors, etc. At the lower level, the Core Engine's main interactions are through the PanelConnect API, which handles all communication with the security panel, and the gateway Interface, which handles communication with the gateway. In an embodiment, both the iHub Interface and PanelConnect API are resident and operating on the touchscreen. In another embodiment, the PanelConnect API runs on the gateway or other device that provides security system interaction and is accessed by the touchscreen through a web services interface.
The Core Engine also handles application and service level persistent and cached memory functions, as well as the dynamic provisioning of content and widgets, including but not limited to: flash memory management, local widget and content caching, widget version management (download, cache flush new/old content versions), as well as the caching and synchronization of user preferences. As a portion of these services the Core engine incorporates the bootloader functionality that is responsible for maintaining a consistent software image on the touchscreen, and acts as the client agent for all software updates. The bootloader is configured to ensure full update redundancy so that unsuccessful downloads cannot corrupt the integrated security system.
Video management is provided as a set of web services by the Core Engine. Video management includes the retrieval and playback of local video feeds as well as remote control and management of cameras (all through iControl CameraConnect technology).
Both the high level application layer and the mid-level core engine of the touchscreen can make calls to the network. Any call to the network made by the application layer is automatically handed off to a local caching proxy, which determines whether the request should be handled locally. Many of the requests from the application layer are web services API requests, although such requests could be satisfied by the iControl servers, they are handled directly by the touchscreen and the gateway. Requests that get through the caching proxy are checked against a white list of acceptable sites, and, if they match, are sent off through the network interface to the gateway. Included in the Network Subsystem is a set of network services including HTTP, HTTPS, and server-level authentication functions to manage the secure client-server interface. Storage and management of certificates is incorporated as a part of the network services layer.
Server components of the integrated security system servers support interactive content services on the touchscreen. These server components include, but are not limited to the content manager, registry manager, network manager, and global registry, each of which is described herein.
The Content Manager oversees aspects of handling widget data and raw content on the touchscreen. Once created and validated by the service provider, widgets are ‘ingested’ to the Content Manager, and then become available as downloadable services through the integrated security system Content Management APIs. The Content manager maintains versions and timestamp information, and connects to the raw data contained in the backend Content Store database. When a widget is updated (or new content becomes available) all clients registering interest in a widget are systematically updated as needed (a process that can be configured at an account, locale, or system-wide level).
The Registry Manager handles user data, and provisioning accounts, including information about widgets the user has decided to install, and the user preferences for these widgets.
The Network Manager handles getting and setting state for all devices on the integrated security system network (e.g., sensors, panels, cameras, etc.). The Network manager synchronizes with the gateway, the advanced touchscreen, and the subscriber database.
The Global Registry is a primary starting point server for all client services, and is a logical referral service that abstracts specific server locations/addresses from clients (touchscreen, gateway 102, desktop widgets, etc.). This approach enables easy scaling/migration of server farms.
The touchscreen of an embodiment operates wirelessly with a premise security system. The touchscreen of an embodiment incorporates an RF transceiver component that either communicates directly with the sensors and/or security panel over the panel's proprietary RF frequency, or the touchscreen communicates wirelessly to the gateway over 802.11, Ethernet, or other IP-based communications channel, as described in detail herein. In the latter case the gateway implements the PanelConnect interface and communicates directly to the security panel and/or sensors over wireless or wired networks as described in detail above.
The touchscreen of an embodiment is configured to operate with multiple security systems through the use of an abstracted security system interface. In this embodiment, the PanelConnect API can be configured to support a plurality of proprietary security system interfaces, either simultaneously or individually as described herein. In one embodiment of this approach, the touchscreen incorporates multiple physical interfaces to security panels (e.g. GE Security RS-485, Honeywell RF, etc.) in addition to the PanelConnect API implemented to support multiple security interfaces. The change needed to support this in PanelConnect is a configuration parameter specifying the panel type connection that is being utilized.
So for example, the setARMState( ) function is called with an additional parameter (e.g., Armstate=setARMState(type=“ARM STAY|ARM AWAY|DISARM”, Parameters=“ExitDelay=30|Lights=OFF”, panelType=“GE Concord4 RS485”)). The ‘panelType’ parameter is used by the setARMState function (and in practice by all of the PanelConnect functions) to select an algorithm appropriate to the specific panel out of a plurality of alogorithms.
The touchscreen of an embodiment is self-installable. Consequently, the touchscreen provides a ‘wizard’ approach similar to that used in traditional computer installations (e.g. InstallShield). The wizard can be resident on the touchscreen, accessible through a web interface, or both. In one embodiment of a touchscreen self-installation process, the service provider can associate devices (sensors, touchscreens, security panels, lighting controls, etc.) remotely using a web-based administrator interface.
The touchscreen of an embodiment includes a battery backup system for a security touchscreen. The touchscreen incorporates a standard Li-ion or other battery and charging circuitry to allow continued operation in the event of a power outage. In an embodiment the battery is physically located and connected within the touchscreen enclosure. In another embodiment the battery is located as a part of the power transformer, or in between the power transformer and the touchscreen.
The example configurations of the integrated security system described above with reference to
The touchscreen of this alternative embodiment integrates the components of the gateway with the components of the touchscreen as described herein. More specifically, the touchscreen of this alternative embodiment includes software or applications described above with reference to
As standards evolve, and new encryption and authentication methods are proven to be useful, and older mechanisms proven to be breakable, the security manager can be upgraded “over the air” to provide new and better security for communications between the iConnect server and the gateway application, and locally at the premises to remove any risk of eavesdropping on camera communications.
A Remote Firmware Download module 306 of the touchscreen allows for seamless and secure updates to the gateway firmware through the iControl Maintenance Application on the server 104, providing a transparent, hassle-free mechanism for the service provider to deploy new features and bug fixes to the installed user base. The firmware download mechanism is tolerant of connection loss, power interruption and user interventions (both intentional and unintentional). Such robustness reduces down time and customer support issues. Touchscreen firmware can be remotely download either for one touchscreen at a time, a group of touchscreen, or in batches.
The Automations engine 308 of the touchscreen manages the user-defined rules of interaction between the different devices (e.g. when door opens turn on the light). Though the automation rules are programmed and reside at the portal/server level, they are cached at the gateway level in order to provide short latency between device triggers and actions.
DeviceConnect 310 of the touchscreen touchscreen includes definitions of all supported devices (e.g., cameras, security panels, sensors, etc.) using a standardized plug-in architecture. The DeviceConnect module 310 offers an interface that can be used to quickly add support for any new device as well as enabling interoperability between devices that use different technologies/protocols. For common device types, pre-defined sub-modules have been defined, making supporting new devices of these types even easier. SensorConnect 312 is provided for adding new sensors, CameraConnect 316 for adding IP cameras, and PanelConnect 314 for adding home security panels.
The Schedules engine 318 of the touchscreen is responsible for executing the user defined schedules (e.g., take a picture every five minutes; every day at 8 am set temperature to 65 degrees Fahrenheit, etc.). Though the schedules are programmed and reside at the iConnect server level they are sent to the scheduler within the gateway application of the touchscreen. The Schedules Engine 318 then interfaces with SensorConnect 312 to ensure that scheduled events occur at precisely the desired time.
The Device Management module 320 of the touchscreen is in charge of all discovery, installation and configuration of both wired and wireless IP devices (e.g., cameras, etc.) coupled or connected to the system. Networked IP devices, such as those used in the integrated security system, require user configuration of many IP and security parameters, and the device management module of an embodiment handles the details of this configuration. The device management module also manages the video routing module described below.
The video routing engine 322 of the touchscreen is responsible for delivering seamless video streams to the user with zero-configuration. Through a multi-step, staged approach the video routing engine uses a combination of UPnP port-forwarding, relay server routing and STUN/TURN peer-to-peer routing. The video routing engine is described in detail in the Related Applications.
The gateway of an embodiment, whether a stand-along component or integrated with a touchscreen, enables couplings or connections and thus the flow or integration of information between various components of the host premises and various types and/or combinations of IP devices, where the components of the host premises include a network (e.g., LAN) and/or a security system or subsystem to name a few. Consequently, the gateway controls the association between and the flow of information or data between the components of the host premises. For example, the gateway of an embodiment forms a sub-network coupled to another network (e.g., WAN, LAN, etc.), with the sub-network including IP devices. The gateway further enables the association of the IP devices of the sub-network with appropriate systems on the premises (e.g., security system, etc.). Therefore, for example, the gateway can form a sub-network of IP devices configured for security functions, and associate the sub-network only with the premises security system, thereby segregating the IP devices dedicated to security from other IP devices that may be coupled to another network on the premises.

In an example embodiment,
An embodiment of the IP device discovery and management begins with a user or installer activating 1302 the gateway and initiating 1304 the install mode of the system. This places the gateway in an install mode. Once in install mode, the gateway shifts to a default (Install) Wifi configuration. This setting will match the default setting for other integrated security system-enabled devices that have been pre-configured to work with the integrated security system. The gateway will then begin to provide 1306 DHCP addresses for these IP devices. Once the devices have acquired a new DHCP address from the gateway, those devices are available for configuration into a new secured Wifi network setting.
The user or installer of the system selects 1308 all devices that have been identified as available for inclusion into the integrated security system. The user may select these devices by their unique IDs via a web page, Touchscreen, or other client interface. The gateway provides 1310 data as appropriate to the devices. Once selected, the devices are configured 1312 with appropriate secured Wifi settings, including SSID and WPA/WPA-2 keys that are used once the gateway switches back to the secured sandbox configuration from the “Install” settings. Other settings are also configured as appropriate for that type of device. Once all devices have been configured, the user is notified and the user can exit install mode. At this point all devices will have been registered 1314 with the integrated security system servers.
The installer switches 1316 the gateway to an operational mode, and the gateway instructs or directs 1318 all newly configured devices to switch to the “secured” Wifi sandbox settings. The gateway then switches 1320 to the “secured” Wifi settings. Once the devices identify that the gateway is active on the “secured” network, they request new DHCP addresses from the gateway which, in response, provides 1322 the new addresses. The devices with the new addresses are then operational 1324 on the secured network.
In order to ensure the highest level of security on the secured network, the gateway can create or generate a dynamic network security configuration based on the unique ID and private key in the gateway, coupled with a randomizing factor that can be based on online time or other inputs. This guarantees the uniqueness of the gateway secured network configuration.
To enable the highest level of performance, the gateway analyzes the RF spectrum of the 802.11x network and determines which frequency band/channel it should select to run.
An alternative embodiment of the camera/IP device management process leverages the local ethernet connection of the sandbox network on the gateway. This alternative process is similar to the Wifi discovery embodiment described above, except the user connects the targeted device to the ethernet port of the sandbox network to begin the process. This alternative embodiment accommodates devices that have not been pre-configured with the default “Install” configuration for the integrated security system.
This alternative embodiment of the IP device discovery and management begins with the user/installer placing the system into install mode. The user is instructed to attach an IP device to be installed to the sandbox Ethernet port of the gateway. The IP device requests a DHCP address from the gateway which, in response to the request, provides the address. The user is presented the device and is asked if he/she wants to install the device. If yes, the system configures the device with the secured Wifi settings and other device-specific settings (e.g., camera settings for video length, image quality etc.). The user is next instructed to disconnect the device from the ethernet port. The device is now available for use on the secured sandbox network.
Referring to
In an embodiment of this security system connection, the touchscreen 1403 communicates to the gateway 1402, and has no direct communication with the security panel. In this embodiment, the touchscreen core application 1410 accesses the remote service APIs 1412 which provide security system functionality (e.g. ARM/DISARM panel, sensor state, get/set panel configuration parameters, initiate or get alarm events, etc.). In an embodiment, the remote service APIs 1412 implement one or more of the following functions, but the embodiment is not so limited: Armstate=setARMState(type=“ARM STAY| ARM AWAY| DISARM”, Parameters=“ExitDelay=30|Lights=OFF”); sensorState=getSensors(type=“ALL|SensorName|SensorNameList”); result=setSensorState(SensorName, parameters=“Option1, Options2, . . . Option n”); interruptHandler=SensorEvent( ); and, interruptHandler=alarmEvent( ).
Functions of the remote service APIs 1412 of an embodiment use a remote PanelConnect API 1424 which which resides in memory on the gateway 1402. The touchscreen 1403 communicates with the gateway 1402 through a suitable network interface such as an Ethernet or 802.11 RF connection, for example. The remote PanelConnect API 1424 provides the underlying Security System Interfaces 1426 used to communicate with and control one or more types of security panel via wired link 1430 and/or RF link 3. The PanelConnect API 1224 provides responses and input to the remote services APIs 1426, and in turn translates function calls and data to and from the specific protocols and functions supported by a specific implementation of a Security Panel (e.g. a GE Security Simon XT or Honeywell Vista 20P). In an embodiment, the PanelConnect API 1224 uses a 345 MHz RF transceiver or receiver hardware/firmware module to communicate wirelessly to the security panel and directly to a set of 345 MHz RF-enabled sensors and devices, but the embodiment is not so limited.
The gateway of an alternative embodiment communicates over a wired physical coupling or connection to the security panel using the panel's specific wired hardware (bus) interface and the panel's bus-level protocol.
In an alternative embodiment, the Touchscreen 1403 implements the same PanelConnect API 1414 locally on the Touchscreen 1403, communicating directly with the Security Panel 2 and/or Sensors 2 over the proprietary RF link or over a wired link for that system. In this embodiment the Touchscreen 1403, instead of the gateway 1402, incorporates the 345 MHz RF transceiver to communicate directly with Security Panel 2 or Sensors 2 over the RF link 2. In the case of a wired link the Touchscreen 1403 incorporates the real-time hardware (e.g. a PIC chip and RS232-variant serial link) to physically connect to and satisfy the specific bus-level timing requirements of the SecurityPanel2.
In yet another alternative embodiment, either the gateway 1402 or the Touchscreen 1403 implements the remote service APIs. This embodiment includes a Cricket device (“Cricket”) which comprises but is not limited to the following components: a processor (suitable for handling 802.11 protocols and processing, as well as the bus timing requirements of SecurityPanel1); an 802.11 (WiFi) client IP interface chip; and, a serial bus interface chip that implements variants of RS232 or RS485, depending on the specific Security Panel.
The Cricket also implements the full PanelConnect APIs such that it can perform the same functions as the case where the gateway implements the PanelConnect APIs. In this embodiment, the touchscreen core application 1410 calls functions in the remote service APIs 1412 (such as setArmState( )). These functions in turn couple or connect to the remote Cricket through a standard IP connection (“Cricket IP Link”) (e.g., Ethernet, Homeplug, the gateway's proprietary Wifi network, etc.). The Cricket in turn implements the PanelConnect API, which responds to the request from the touchscreen core application, and performs the appropriate function using the proprietary panel interface. This interface uses either the wireless or wired proprietary protocol for the specific security panel and/or sensors.
Unlike conventional systems that extend an existing security system, the system of an embodiment operates utilizing the proprietary wireless protocols of the security system manufacturer. In one illustrative embodiment, the gateway is an embedded computer with an IP LAN and WAN connection and a plurality of RF transceivers and software protocol modules capable of communicating with a plurality of security systems each with a potentially different RF and software protocol interface. After the gateway has completed the discovery and learning 1540 of sensors and has been integrated 1550 as a virtual control device in the extant security system, the system becomes operational. Thus, the security system and associated sensors are presented 1550 as accessible devices to a potential plurality of user interface subsystems.
The system of an embodiment integrates 1560 the functionality of the extant security system with other non-security devices including but not limited to IP cameras, touchscreens, lighting controls, door locking mechanisms, which may be controlled via RF, wired, or powerline-based networking mechanisms supported by the gateway or servers.
The system of an embodiment provides a user interface subsystem 1570 enabling a user to monitor, manage, and control the system and associated sensors and security systems. In an embodiment of the system, a user interface subsystem is an HTML/XML/Javascript/Java/AJAX/Flash presentation of a monitoring and control application, enabling users to view the state of all sensors and controllers in the extant security system from a web browser or equivalent operating on a computer, PDA, mobile phone, or other consumer device.
In another illustrative embodiment of the system described herein, a user interface subsystem is an HTML/XML/Javascript/Java/AJAX presentation of a monitoring and control application, enabling users to combine the monitoring and control of the extant security system and sensors with the monitoring and control of non-security devices including but not limited to IP cameras, touchscreens, lighting controls, door locking mechanisms.
In another illustrative embodiment of the system described herein, a user interface subsystem is a mobile phone application enabling users to monitor and control the extant security system as well as other non-security devices.
In another illustrative embodiment of the system described herein, a user interface subsystem is an application running on a keypad or touchscreen device enabling users to monitor and control the extant security system as well as other non-security devices.
In another illustrative embodiment of the system described herein, a user interface subsystem is an application operating on a TV or set-top box connected to a TV enabling users to monitor and control the extant security system as well as other non-security devices.
Moreover, other elements of the system of an embodiment may be conventional, well-known elements that need not be explained in detail herein. For example, security system 1610 could be any type home or business security system, such devices including but not limited to a standalone RF home security system or a non-RF-capable wired home security system with an add-on RF interface module. In the integrated security system 1600 of this example, security system 1610 includes an RF-capable wireless security panel (WSP) 1611 that acts as the master controller for security system 1610. Well-known examples of such a WSP include the GE Security Concord, Networx, and Simon panels, the Honeywell Vista and Lynx panels, and similar panels from DSC and Napco, to name a few. A wireless module 1614 includes the RF hardware and protocol software necessary to enable communication with and control of a plurality of wireless devices 1613. WSP 1611 may also manage wired devices 1614 physically connected to WSP 1611 with an RS232 or RS485 or Ethernet connection or similar such wired interface.
In an implementation consistent with the systems and methods described herein, Gateway 1620 provides the interface between security system 1610 and LAN and/or WAN for purposes of remote control, monitoring, and management. Gateway 1620 communicates with an external web server 1640, database 1650, and application server 1660 over network 1630 (which may comprise WAN, LAN, or a combination thereof). In this example system, application logic, remote user interface functionality, as well as user state and account are managed by the combination of these remote servers. Gateway 1620 includes server connection manager 1621, a software interface module responsible for all server communication over network 1630. Event manager 1622 implements the main event loop for Gateway 1620, processing events received from device manager 1624 (communicating with non-security system devices including but not limited to IP cameras, wireless thermostats, or remote door locks). Event manager 1622 further processes events and control messages from and to security system 1610 by utilizing WSP manager 1623.
WSP manager 1623 and device manager 1624 both rely upon wireless protocol manager 1626 which receives and stores the proprietary or standards-based protocols required to support security system 1610 as well as any other devices interfacing with gateway 1620. WSP manager 1623 further utilizes the comprehensive protocols and interface algorithms for a plurality of security systems 1610 stored in the WSP DB client database associated with wireless protocol manager 1626. These various components implement the software logic and protocols necessary to communicate with and manager devices and security systems 1610. Wireless Transceiver hardware modules 1625 are then used to implement the physical RF communications link to such devices and security systems 1610. An illustrative wireless transceiver 1625 is the GE Security Dialog circuit board, implementing a 319.5 MHz two-way RF transceiver module. In this example, RF Link 1670 represents the 319.5 MHz RF communication link, enabling gateway 1620 to monitor and control WSP 1611 and associated wireless and wired devices 1613 and 1614, respectively.
In one embodiment, server connection manager 1621 requests and receives a set of wireless protocols for a specific security system 1610 (an illustrative example being that of the GE Security Concord panel and sensors) and stores them in the WSP DB portion of the wireless protocol manager 1626. WSP manager 1623 then utilizes such protocols from wireless protocol manager 1626 to initiate the sequence of processes detailed in
In another embodiment, gateway 1620 incorporates a plurality of wireless transceivers 1625 and associated protocols managed by wireless protocol manager 1626. In this embodiment events and control of multiple heterogeneous devices may be coordinated with WSP 1611, wireless devices 1613, and wired devices 1614. For example a wireless sensor from one manufacturer may be utilized to control a device using a different protocol from a different manufacturer.
In another embodiment, gateway 1620 incorporates a wired interface to security system 1610, and incorporates a plurality of wireless transceivers 1625 and associated protocols managed by wireless protocol manager 1626. In this embodiment events and control of multiple heterogeneous devices may be coordinated with WSP 1611, wireless devices 1613, and wired devices 1614.
Of course, while an illustrative embodiment of an architecture of the system of an embodiment is described in detail herein with respect to
Gateway 1620 utilizes the appropriate protocols to mimic 1760 the first identified device 1614. In this operation gateway 1620 identifies itself using the unique or pseudo-unique identifier of the first found device 1614, and sends an appropriate change of state message over RF Link 1670. In the event that WSP 1611 responds to this change of state message, the device 1614 is then added 1770 to the system in database 1650. Gateway 1620 associates 1780 any other information (such as zone name or token-based identifier) with this device 1614 in database 1650, enabling gateway 1620, user interface modules, or any application to retrieve this associated information.
In the event that WSP 1611 does not respond to the change of state message, the device 1614 is not added 1770 to the system in database 1650, and this device 1614 is identified as not being a part of security system 1610 with a flag, and is either ignored or added as an independent device, at the discretion of the system provisioning rules. Operations hereunder repeat 1785 operations 1760, 1770, 1780 for all devices 1614 if applicable. Once all devices 1614 have been tested in this way, the system begins operation 1790.
In another embodiment, gateway 1620 utilizes a wired connection to WSP 1611, but also incorporates a wireless transceiver 1625 to communicate directly with devices 1614. In this embodiment, operations under 1720 above are removed, and operations under 1740 above are modified so the system of this embodiment utilizes wireline protocols to add itself as an authorized control device in security system 1610.
A description of an example embodiment follows in which the Gateway (
The automatic security system installation begins with the assignment of an authorization key to components of the security system (e.g., gateway, kit including the gateway, etc.). The assignment of an authorization key is done in lieu of creating a user account. An installer later places the gateway in a user's premises along with the premises security system. The installer uses a computer to navigate to a web portal (e.g., integrated security system web interface), logs in to the portal, and enters the authorization key of the installed gateway into the web portal for authentication. Once authenticated, the gateway automatically discovers devices at the premises (e.g., sensors, cameras, light controls, etc.) and adds the discovered devices to the system or “network”. The installer assigns names to the devices, and tests operation of the devices back to the server (e.g., did the door open, did the camera take a picture, etc.). The security device information is optionally pushed or otherwise propagated to a security panel and/or to the server network database. The installer finishes the installation, and instructs the end user on how to create an account, username, and password. At this time the user enters the authorization key which validates the account creation (uses a valid authorization key to associate the network with the user's account). New devices may subsequently be added to the security network in a variety of ways (e.g., user first enters a unique ID for each device/sensor and names it in the server, after which the gateway can automatically discover and configure the device).
A description of another example embodiment follows in which the security system (
GE Security's Dialog network is one of the most widely deployed and tested wireless security systems in the world. The physical RF network is based on a 319.5 MHz unlicensed spectrum, with a bandwidth supporting up to 19 Kbps communications. Typical use of this bandwidth—even in conjunction with the integrated security system—is far less than that. Devices on this network can support either one-way communication (either a transmitter or a receiver) or two-way communication (a transceiver). Certain GE Simon, Simon XT, and Concord security control panels incorporate a two-way transceiver as a standard component. The gateway also incorporates the same two-way transceiver card. The physical link layer of the network is managed by the transceiver module hardware and firmware, while the coded payload bitstreams are made available to the application layer for processing.
Sensors in the Dialog network typically use a 60-bit protocol for communicating with the security panel transceiver, while security system keypads and the gateway use the encrypted 80-bit protocol. The Dialog network is configured for reliability, as well as low-power usage. Many devices are supervised, i.e. they are regularly monitored by the system ‘master’ (typically a GE security panel), while still maintaining excellent power usage characteristics. A typical door window sensor has a battery life in excess of 5-7 years.
The gateway has two modes of operation in the Dialog network: a first mode of operation is when the gateway is configured or operates as a ‘slave’ to the GE security panel; a second mode of operation is when the gateway is configured or operates as a ‘master’ to the system in the event a security panel is not present. In both configurations, the gateway has the ability to ‘listen’ to network traffic, enabling the gateway to continually keep track of the status of all devices in the system. Similarly, in both situations the gateway can address and control devices that support setting adjustments (such as the GE wireless thermostat).
In the configuration in which the gateway acts as a ‘slave’ to the security panel, the gateway is ‘learned into’ the system as a GE wireless keypad. In this mode of operation, the gateway emulates a security system keypad when managing the security panel, and can query the security panel for status and ‘listen’ to security panel events (such as alarm events).
The gateway incorporates an RF Transceiver manufactured by GE Security, but is not so limited. This transceiver implements the Dialog protocols and handles all network message transmissions, receptions, and timing. As such, the physical, link, and protocol layers of the communications between the gateway and any GE device in the Dialog network are totally compliant with GE Security specifications.
At the application level, the gateway emulates the behavior of a GE wireless keypad utilizing the GE Security 80-bit encrypted protocol, and only supported protocols and network traffic are generated by the gateway. Extensions to the Dialog RF protocol of an embodiment enable full control and configuration of the panel, and iControl can both automate installation and sensor enrollment as well as direct configuration downloads for the panel under these protocol extensions.
As described above, the gateway participates in the GE Security network at the customer premises. Because the gateway has intelligence and a two-way transceiver, it can ‘hear’ all of the traffic on that network. The gateway makes use of the periodic sensor updates, state changes, and supervisory signals of the network to maintain a current state of the premises. This data is relayed to the integrated security system server (e.g.,
The gateway can directly (or indirectly through the Simon XT panel) control two-way devices on the network. For example, the gateway can direct a GE Security Thermostat to change its setting to ‘Cool’ from ‘Off’, as well as request an update on the current temperature of the room. The gateway performs these functions using the existing GE Dialog protocols, with little to no impact on the network; a gateway device control or data request takes only a few dozen bytes of data in a network that can support 19 Kbps.
By enrolling with the Simon XT as a wireless keypad, as described herein, the gateway includes data or information of all alarm events, as well as state changes relevant to the security panel. This information is transferred to the gateway as encrypted packets in the same way that the information is transferred to all other wireless keypads on the network.
Because of its status as an authorized keypad, the gateway can also initiate the same panel commands that a keypad can initiate. For example, the gateway can arm or disarm the panel using the standard Dialog protocol for this activity. Other than the monitoring of standard alarm events like other network keypads, the only incremental data traffic on the network as a result of the gateway is the infrequent remote arm/disarm events that the gateway initiates, or infrequent queries on the state of the panel.
The gateway is enrolled into the Simon XT panel as a ‘slave’ device which, in an embodiment, is a wireless keypad. This enables the gateway for all necessary functionality for operating the Simon XT system remotely, as well as combining the actions and information of non-security devices such as lighting or door locks with GE Security devices. The only resource taken up by the gateway in this scenario is one wireless zone (sensor ID).
The gateway of an embodiment supports three forms of sensor and panel enrollment/installation into the integrated security system, but is not limited to this number of enrollment/installation options. The enrollment/installation options of an embodiment include installer installation, kitting, and panel, each of which is described below.
Under the installer option, the installer enters the sensor IDs at time of installation into the integrated security system web portal or iScreen. This technique is supported in all configurations and installations.
Kits can be pre-provisioned using integrated security system provisioning applications when using the kitting option. At kitting time, multiple sensors are automatically associated with an account, and at install time there is no additional work required.
In the case where a panel is installed with sensors already enrolled (i.e. using the GE Simon XT enrollment process), the gateway has the capability to automatically extract the sensor information from the system and incorporate it into the user account on the integrated security system server.
The gateway and integrated security system of an embodiment uses an auto-learn process for sensor and panel enrollment in an embodiment. The deployment approach of an embodiment can use additional interfaces that GE Security is adding to the Simon XT panel. With these interfaces, the gateway has the capability to remotely enroll sensors in the panel automatically. The interfaces include, but are not limited to, the following: EnrolIDevice(ID, type, name, zone, group); SetDeviceParameters(ID, type, Name, zone, group), GetDeviceParameters(zone); and RemoveDevice(zone).
The integrated security system incorporates these new interfaces into the system, providing the following install process. The install process can include integrated security system logistics to handle kitting and pre-provisioning. Pre-kitting and logistics can include a pre-provisioning kitting tool provided by integrated security system that enables a security system vendor or provider (“provider”) to offer pre-packaged initial ‘kits’. This is not required but is recommended for simplifying the install process. This example assumes a ‘Basic’ kit is preassembled and includes one (1) Simon XT, three (3) Door/window sensors, one (1) motion sensor, one (1) gateway, one (1) keyfob, two (2) cameras, and ethernet cables. The kit also includes a sticker page with all Zones (1-24) and Names (full name list).
The provider uses the integrated security system kitting tool to assemble ‘Basic’ kit packages. The contents of different types of starter kits may be defined by the provider. At the distribution warehouse, a worker uses a bar code scanner to scan each sensor and the gateway as it is packed into the box. An ID label is created that is attached to the box. The scanning process automatically associates all the devices with one kit, and the new ID label is the unique identifier of the kit. These boxes are then sent to the provider for distribution to installer warehouses. Individual sensors, cameras, etc. are also sent to the provider installer warehouse. Each is labeled with its own barcode/ID.
An installation and enrollment procedure of a security system including a gateway is described below as one example of the installation process.
An installation and enrollment procedure of a security system including a gateway is described below as an alternative example of the installation process. This installation process is for use for enrolling sensors into the SimonXT and integrated security system and is compatible with all existing GE Simon panels.
The integrated security system supports all pre-kitting functionality described in the installation process above. However, for the purpose of the following example, no kitting is used.
The panel of an embodiment can be programmed remotely. The CMS pushes new programming to SimonXT over a telephone or GPRS link. Optionally, iControl and GE provide a broadband link or coupling to the gateway and then a link from the gateway to the Simon XT over GE RF.
In addition to the configurations described above, the gateway of an embodiment supports takeover configurations in which it is introduced or added into a legacy security system. A description of example takeover configurations follow in which the security system (
The security system can optionally include RF wireless sensors (e.g., GE wireless sensors utilizing the GE Dialog RF technology), IP cameras, a GE-iControl Touchscreen (the touchscreen is assumed to be an optional component in the configurations described herein, and is thus treated separately from the iHub; in systems in which the touchscreen is a component of the base security package, the integrated iScreen (available from iControl Networks, Palo Alto, Calif.) can be used to combine iHub technology with the touchscreen in a single unit), and Z-Wave devices to name a few.
The takeover configurations described below assume takeover by a “new” system of an embodiment of a security system provided by another third party vendor, referred to herein as an “original” or “legacy” system. Generally, the takeover begins with removal of the control panel and keypad of the legacy system. A GE Concord panel is installed to replace the control panel of the legacy system along with an iHub with GPRS Modem. The legacy system sensors are then connected or wired to the Concord panel, and a GE keypad or touchscreen is installed to replace the control panel of the legacy system. The iHub includes the iControl RF card, which is compatible with the legacy system. The iHub finds and manages the wireless sensors of the legacy system, and learns the sensors into the Concord by emulating the corresponding GE sensors. The iHub effectively acts as a relay for legacy wireless sensors.
Once takeover is complete, the new security system provides a homogeneous system that removes the compromises inherent in taking over or replacing a legacy system. For example, the new system provides a modern touchscreen that may include additional functionality, new services, and supports integration of sensors from various manufacturers. Furthermore, lower support costs can be realized because call centers, installers, etc. are only required to support one architecture. Additionally, there is minimal install cost because only the panel is required to be replaced as a result of the configuration flexibility offered by the iHub.
The system takeover configurations described below include but are not limited to a dedicated wireless configuration, a dedicated wireless configuration that includes a touchscreen, and a fished Ethernet configuration. Each of these configurations is described in detail below.
The GE-iControl Touchscreen can be used with either of an 802.11 connection or Ethernet connection with the iHub. Because the takeover involves a GE Concord panel (or Simon XT), the touchscreen is always an option. No extra wiring is required for the touchscreen as it can use the 4-wire set from the replaced keypad of the legacy system. This provides power, battery backup (through Concord), and data link (RS485 Superbus 2000) between Concord and touchscreen. The touchscreen receives its broadband connectivity through the dedicated 802.11 link to the iHub.
The takeover installation process is similar to the installation process described above, except the control panel of the legacy system is replaced; therefore, only the differences with the installation described above are provided here. The takeover approach of an embodiment uses the existing RS485 control interfaces that GE Security and iControl support with the iHub, touchscreen, and Concord panel. With these interfaces, the iHub is capable of automatically enrolling sensors in the panel. The exception is the leverage of an iControl RF card compatible with legacy systems to ‘takeover’ existing RF sensors. A description of the takeover installation process follows.
During the installation process, the iHub uses an RF Takeover Card to automatically extract all sensor IDs, zones, and names from the legacy panel. The installer removes connections at the legacy panel from hardwired wired sensors and labels each with the zone. The installer pulls the legacy panel and replaces it with the GE Concord panel. The installer also pulls the existing legacy keypad and replaces it with either a GE keypad or a GE-iControl touchscreen. The installer connects legacy hardwired sensors to appropriate wired zone (from labels) on the Concord. The installer connects the iHub to the local network and connects the iHub RS485 interface to the Concord panel. The iHub automatically ‘enrolls’ legacy RF sensors into the Concord panel as GE sensors (maps IDs), and pushes or otherwise propagates other information gathered from HW panel (zone, name, group). The installer performs a test of all sensors back to CMS. In operation, the iHub relays legacy sensor data to the Concord panel, emulating equivalent GE sensor behavior and protocols.
The areas of the installation process particular to the legacy takeover include how the iHub extracts sensor info from the legacy panel and how the iHub automatically enrolls legacy RF sensors and populates Concord with wired zone information. Each of these areas is described below.
In having the iHub extract sensor information from the legacy panel, the installer ‘enrolls’ iHub into the legacy panel as a wireless keypad (use install code and house ID—available from panel). The iHub legacy RF Takeover Card is a compatible legacy RF transceiver. The installer uses the web portal to place iHub into ‘Takeover Mode’, and the web portal the automatically instructs the iHub to begin extraction. The iHub queries the panel over the RF link (to get all zone information for all sensors, wired and RF). The iHub then stores the legacy sensor information received during the queries on the iConnect server.
The iHub also automatically enrolls legacy RF sensors and populates Concord with wired zone information. In so doing, the installer selects ‘Enroll legacy Sensors into Concord’ (next step in ‘Takeover’ process on web portal). The iHub automatically queries the iConnect server, and downloads legacy sensor information previously extracted. The downloaded information includes an ID mapping from legacy ID to ‘spoofed’ GE ID. This mapping is stored on the server as part of the sensor information (e.g., the iConnect server knows that the sensor is a legacy sensor acting in GE mode). The iHub instructs Concord to go into install mode, and sends appropriate Superbus 2000 commands for sensor learning to the panel. For each sensor, the ‘spoofed’ GE ID is loaded, and zone, name, and group are set based on information extracted from legacy panel. Upon completion, the iHub notifies the server, and the web portal is updated to reflect next phase of Takeover (e.g., ‘Test Sensors’).
Sensors are tested in the same manner as described above. When a HW sensor is triggered, the signal is captured by the iHub legacy RF Takeover Card, translated to the equivalent GE RF sensor signal, and pushed to the panel as a sensor event on the SuperBus 2000 wires.
In support of remote programming of the panel, CMS pushes new programming to Concord over a phone line, or to the iConnect CMS/Alarm Server API, which in turn pushes the programming to the iflub. The iHub uses the Concord Superbus 2000 RS485 link to push the programming to the Concord panel.
Components of the gateway of the integrated security system described herein control discovery, installation and configuration of both wired and wireless IP devices (e.g., cameras, etc.) coupled or connected to the system, as described herein with reference to
By way of reference, conventional video cameras have the ability to stream digital video in a variety of formats and over a variety of networks. Internet protocol (IP) video cameras, which include video cameras using an IP transport network (e.g., Ethernet, WiFi (IEEE 802.11 standards), etc.) are prevalent and increasingly being utilized in home monitoring and security system applications. With the proliferation of the internet, Ethernet and WiFi local area networks (LANs) and advanced wide area networks (WANs) that offer high bandwidth, low latency connections (broadband), as well as more advanced wireless WAN data networks (e.g. GPRS or CDMA 1×RTT), there increasingly exists the networking capability to extend traditional security systems to offer IP-based video. However, a fundamental reason for such IP video in a security system is to enable a user or security provider to monitor live or otherwise streamed video from outside the host premises (and the associated LAN).
The conventional solution to this problem has involved a technique known as ‘port forwarding’, whereby a ‘port’ on the LAN's router/firewall is assigned to the specific LAN IP address for an IP camera, or a proxy to that camera. Once a port has been ‘forwarded’ in this manner, a computer external to the LAN can address the LAN's router directly, and request access to that port. This access request is then forwarded by the router directly to the IP address specified, the IP camera or proxy. In this way an external device can directly access an IP camera within the LAN and view or control the streamed video.
The issues with this conventional approach include the following: port forwarding is highly technical and most users do not know how/why to do it; automatic port forwarding is difficult and problematic using emerging standards like UPnP; the camera IP address is often reset in response to a power outage/router reboot event; there are many different routers with different ways/capabilities for port forwarding. In short, although port forwarding can work, it is frequently less than adequate to support a broadly deployed security solution utilizing IP cameras.
Another approach to accessing streaming video externally to a LAN utilizes peer-to-peer networking technology. So-called peer-to-peer networks, which includes networks in which a device or client is connected directly to another device or client, typically over a Wide Area Network (WAN) and without a persistent server connection, are increasingly common. In addition to being used for the sharing of files between computers (e.g., Napster and KaZaa), peer-to-peer networks have also been more recently utilized to facilitate direct audio and media streaming in applications such as Skype. In these cases, the peer-to-peer communications have been utilized to enable telephony-style voice communications and video conferencing between two computers, each enabled with an IP-based microphone, speaker, and video camera. A fundamental reason for adopting such peer-to-peer technology is the ability to transparently ‘punch through’ LAN firewalls to enable external access to the streaming voice and video content, and to do so in a way that scales to tens of millions of users without creating an untenable server load.
A limitation of the conventional peer-to-peer video transport lies in the personal computer (PC)-centric nature of the solution. Each of the conventional solutions uses a highly capable PC connected to the video camera, with the PC providing the advanced software functionality required to initiate and manage the peer-to-peer connection with the remote client. A typical security or remote home monitoring system requires multiple cameras, each with its own unique IP address, and only a limited amount of processing capability in each camera such that the conventional PC-centric approach cannot easily solve the need. Instead of a typical PC-centric architecture with three components (a “3-way IP Video System”) that include a computer device with video camera, a mediating server, and a PC client with video display capability, the conventional security system adds a plurality of fourth components that are standalone IP video cameras (requiring a “4-way IP Video System”), another less-than-ideal solution.
In accordance with the embodiments described herein, IP camera management systems and methods are provided that enable a consumer or security provider to easily and automatically configure and manage IP cameras located at a customer premise. Using this system IP camera management may be extended to remote control and monitoring from outside the firewall and router of the customer premise.

Alternatively, with reference to
When a server relay is present 2330, the IP camera is instructed 2331 to stream to the server, and the connection is managed 2332 through the server. In response to the stream terminating 2351, operations return to gateway operation 2313, and waits to receive another request 2320 for a stream from one of the plurality of IP video cameras available on the LAN.
When a server relay is not present 2330, the requestor's WAN IP address/port is provided 2333 to the gateway or gateway relay. When a gateway relay is present 2340, the IP camera is instructed 2341 to stream to the gateway, and the gateway relays 2342 the connection to the requestor. In response to the stream terminating 2351, operations return to gateway operation 2313, and waits to receive another request 2320 for a stream from one of the plurality of IP video cameras available on the LAN. When a gateway relay is not present 2340, the IP camera is instructed 2343 to stream to an address, and a handoff 2344 is made resulting in direct communication between the camera and the requestor. In response to the stream terminating 2351, operations return to gateway operation 2313, and waits to receive another request 2320 from one of the plurality of IP video cameras available on the LAN.
The integrated security system of an embodiment supports numerous video stream formats or types of video streams. Supported video streams include, but are not limited to, Motion Picture Experts Group (MPEG)-4 (MPEG-4)/Real-Time Streaming Protocol (RTSP), MPEG-4 over Hypertext Transfer Protocol (HTTP), and Motion Joint Photographic Experts Group (JPEG) (MJPEG).
The integrated security system of an embodiment supports the MPEG-4/RTSP video streaming method (supported by video servers and clients) which uses RTSP for the control channel and Real-time Transport Protocol (RTP) for the data channel. Here the RTSP channel is over Transmission Control Protocol (TCP) while the data channel uses User Datagram Protocol (UDP). This method is widely supported by both streaming sources (e.g., cameras) and stream clients (e.g., remote client devices, Apple Quicktime, VideoLAN, IPTV mobile phones, etc).
Encryption can be added to the two channels under MPEG-4/RTSP. For example, the RTSP control channel can be encrypted using SSL/TLS. The data channel can also be encrypted.
If the camera or video stream source inside the home does not support encryption for either RTSP or RTP channels, the gateway located on the LAN can facilitate the encrypted RTSP method by maintaining separate TCP sessions with the video stream source device and with the encrypted RTSP client outside the LAN, and relay all communication between the two sessions. In this situation, any communication between the gateway and the video stream source that is not encrypted could be encrypted by the gateway before being relayed to the RTSP client outside the LAN. In many cases the gateway is an access point for the encrypted and private Wifi network on which the video stream source device is located. This means that communication between the gateway and the video stream source device is encrypted at the network level, and communication between the gateway and the RTSP client is encrypted at the transport level. In this fashion the gateway can compensate for a device that does not support encrypted RTSP.
The integrated security system of an embodiment also supports reverse RTSP. Reverse RTSP includes taking a TCP-based protocol like RTSP, and reversing the roles of client and server (references to “server” include the iControl server, also referred to as the iConnect server) when it comes to TCP session establishment. For example, in standard RTSP the RTSP client is the one that establishes the TCP connection with the stream source server (the server listens on a port for incoming connections). In Reverse RTSP, the RTSP client listens on a port for incoming connections from the stream source server. Once the TCP connection is established, the RTSP client begins sending commands to the server over the TCP connection just as it would in standard RTSP.
When using Reverse RTSP, the video stream source is generally on a LAN, protected by a firewall. Having a device on the LAN initiate the connection to the RTSP client outside the firewall enables easy network traversal.
If the camera or video stream source inside the LAN does not support Reverse RTSP, then the gateway facilitates the Reverse RTSP method by initiating separate TCP sessions with the video stream source device and with the Reverse RTSP client outside the LAN, and then relays all communication between the two sessions. In this fashion the gateway compensates for a stream source device that does not support Reverse RTSP.
As described in the encryption description above, the gateway can further compensate for missing functionalities on the device such as encryption. If the device does not support encryption for either RTSP or RTP channels, the gateway can communicate with the device using these un-encrypted streams, and then encrypt the streams before relaying them out of the LAN to the RTSP Reverse client.
Servers of the integrated security system can compensate for RTSP clients that do not support Reverse RTSP. In this situation, the server accepts TCP connections from both the RTSP client and the Reverse RTSP video stream source (which could be a gateway acting on behalf of a stream source device that does not support Reverse RTSP). The server then relays the control and video streams from the Reverse RTSP video stream source to the RTSP client. The server can further compensate for the encryption capabilities of the RTSP client; if the RTSP client does not support encryption then the server can provide an unencrypted stream to the RTSP client even though an encrypted stream was received from the Reverse RTSP streaming video source.
The integrated security system of an embodiment also supports Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators (NAT) (STUN)/Traversal Using Relay NAT (TURN) peer-to-peer routing. STUN and Turn are techniques for using a server to help establish a peer-to-peer UDP data stream (it does not apply to TCP streams). The bandwidth consumed by the data channel of a video stream is usually many thousands of times larger than that used by the control channel. Consequently, when a peer-to-peer connection for both the RTSP and RTP channels is not possible, there is still a great incentive to use STUN/TURN techniques in order to achieve a peer-to-peer connection for the RTP data channel.
Here, a method referred to herein as RTSP with STUN/TURN is used by the integrated security system. The RTSP with STUN/TURN is a method in which the video streaming device is instructed over the control channel to stream its UDP data channel to a different network address than that of the other end of the control TCP connection (usually the UDP data is simply streamed to the IP address of the RTSP client). The result is that the RTSP or Reverse RTSP TCP channel can be relayed using the gateway and/or the server, while the RTP UDP data channel can flow directly from the video stream source device to the video stream client.
If a video stream source device does not support RTSP with STUN/TURN, the gateway can compensate for the device by relaying the RTSP control channel via the server to the RTSP client, and receiving the RTP data channel and then forwarding it directly to the RTSP with STUN/TURN enabled client. Encryption can also be added here by the gateway.
The integrated security system of an embodiment supports MPEG-4 over HTTP. MPEG-4 over HTTP is similar to MPEG-4 over RTSP except that both the RTSP control channel and the RTP data channel are passed over an HTTP TCP session. Here a single TCP session can be used, splitting it into multiple channels using common HTTP techniques like chunked transfer encoding.
The MPEG-4 over HTTP is generally supported by many video stream clients and server devices, and encryption can easily be added to it using SSL/TLS. Because it uses TCP for both channels, STUN/TURN techniques may not apply in the event that a direct peer-to-peer TCP session between client and server cannot be established.
As described above, encryption can be provided using SSL/TLS taking the form of HTTPS. And as with MPEG-4 over RTSP, a gateway can compensate for a stream source device that does not support encryption by relaying the TCP streams and encrypting the TCP stream between the gateway and the stream client. In many cases the gateway is an access point for the encrypted and private Wifi network on which the video stream source device is located. This means that communication between the gateway and the video stream source device is encrypted at the network level, and communication between the gateway and the video stream client is encrypted at the transport level. In this fashion the gateway can compensate for a device that does not support HTTPS.
As with Reverse RTSP, the integrated security system of an embodiment supports Reverse HTTP. Reverse HTTP includes taking a TCP-based protocol like HTTP, and reversing the roles of client and server when it comes to TCP session establishment. For example, in conventional HTTP the HTTP client is the one that establishes the TCP connection with the server (the server listens on a port for incoming connections). In Reverse HTTP, the HTTP client listens on a port for incoming connections from the server. Once the TCP connection is established, the HTTP client begins sending commands to the server over the TCP connection just as it would in standard HTTP.
When using Reverse HTTP, the video stream source is generally on a LAN, protected by a firewall. Having a device on the LAN initiate the connection to the HTTP client outside the firewall enables easy network traversal.
If the camera or video stream source inside the LAN does not support Reverse HTTP, then the gateway can facilitate the Reverse HTTP method by initiating separate TCP sessions with the video stream source device and with the Reverse HTTP client outside the LAN, and then relay all communication between the two sessions. In this fashion the gateway can compensate for a stream source device that does not support Reverse HTTP.
As described in the encryption description above, the gateway can further compensate for missing functionalities on the device such as encryption. If the device does not support encrypted HTTP (e.g., HTTPS), then the gateway can communicate with the device using HTTP, and then encrypt the TCP stream(s) before relaying out of the LAN to the Reverse HTTP client.
The servers of an embodiment can compensate for HTTP clients that do not support Reverse HTTP. In this situation, the server accepts TCP connections from both the HTTP client and the Reverse HTTP video stream source (which could be a gateway acting on behalf of a stream source device that does not support Reverse HTTP). The server then relays the TCP streams from the Reverse HTTP video stream source to the HTTP client. The server can further compensate for the encryption capabilities of the HTTP client; if the HTTP client does not support encryption then the server can provide an unencrypted stream to the HTTP client even though an encrypted stream was received from the Reverse HTTP streaming video source.
The integrated security system of an embodiment supports MJPEG as described above. MJPEG is a streaming technique in which a series of JPG images are sent as the result of an HTTP request. Because MJPEG streams are transmitted over HTTP, HTTPS can be employed for encryption and most MJPEG clients support the resulting encrypted stream. And as with MPEG-4 over HTTP, a gateway can compensate for a stream source device that does not support encryption by relaying the TCP streams and encrypting the TCP stream between the gateway and the stream client. In many cases the gateway is an access point for the encrypted and private Wifi network on which the video stream source device is located. This means that communication between the gateway and the video stream source device is encrypted at the network level, and communication between the gateway and the video stream client is encrypted at the transport level. In this fashion the gateway can compensate for a device that does not support HTTPS.
The integrated system of an embodiment supports Reverse HTTP. Reverse HTTP includes taking a TCP-based protocol like HTTP, and reversal of the roles of client and server when it comes to TCP session establishment can be employed for MJPEG streams. For example, in standard HTTP the HTTP client is the one who establishes the TCP connection with the server (the server listens on a port for incoming connections). In Reverse HTTP, the HTTP client listens on a port for incoming connections from the server. Once the TCP connection is established, the HTTP client begins sending commands to the server over the TCP connection just as it would in standard HTTP.
When using Reverse HTTP, the video stream source is generally on a LAN, protected by a firewall. Having a device on the LAN initiate the connection to the HTTP client outside the firewall enables network traversal.
If the camera or video stream source inside the LAN does not support Reverse HTTP, then the gateway can facilitate the Reverse HTTP method by initiating separate TCP sessions with the video stream source device and with the Reverse HTTP client outside the LAN, and then relay all communication between the two sessions. In this fashion the gateway can compensate for a stream source device that does not support Reverse HTTP.
As described in the encryption description above, the gateway can further compensate for missing functionalities on the device such as encryption. If the device does not support encrypted HTTP (e.g., HTTPS), then the gateway can communicate with the device using HTTP, and then encrypt the TCP stream(s) before relaying out of the LAN to the Reverse HTTP client.
The servers can compensate for HTTP clients that do not support Reverse HTTP. In this situation, the server accepts TCP connections from both the HTTP client and the Reverse HTTP video stream source (which could be a gateway acting on behalf of a stream source device that does not support Reverse HTTP). The server then relays the TCP streams from the Reverse HTTP video stream source to the HTTP client. The server can further compensate for the encryption capabilities of the HTTP client; if the HTTP client does not support encryption then the server can provide an unencrypted stream to the HTTP client even though an encrypted stream was received from the Reverse HTTP streaming video source.
The integrated security system of an embodiment considers numerous parameters in determining or selecting one of the streaming formats described above for use in transferring video streams. The parameters considered in selecting a streaming format include, but are not limited to, security requirements, client capabilities, device capabilities, and network/system capabilities.
The security requirements for a video stream are considered in determining an applicable streaming format in an embodiment. Security requirements fall into two categories, authentication and privacy, each of which is described below.
Authentication as a security requirement means that stream clients must present credentials in order to obtain a stream. Furthermore, this presentation of credentials should be done in a way that is secure from network snooping and replays. An example of secure authentication is Basic Authentication over HTTPS. Here a username and password are presented over an encrypted HTTPS channel so snooping and replays are prevented. Basic Authentication alone, however, is generally not sufficient for secure authentication.
Because not all streaming clients support SSL/TLS, authentication methods that do not require it are desirable. Such methods include Digest Authentication and one-time requests. A one-time request is a request that can only be made by a client one time, and the server prevents a reuse of the same request. One-time requests are used to control access to a stream source device by stream clients that do not support SSL/TLS. An example here is providing video access to a mobile phone. Typical mobile phone MPEG-4 viewers do not support encryption. In this case, one of the MPEG-4 over RTSP methods described above can be employed to get the video stream relayed to an server. The server can then provide the mobile phone with a one-time request Universal Resource Locator (URL) for the relayed video stream source (via a Wireless Application Protocol (WAP) page). Once the stream ends, the mobile phone would need to obtain another one-time request URL from the server (via WAP, for example) in order to view the stream again.
Privacy as a security requirement means that the contents of the video stream must be encrypted. This is a requirement that may be impossible to satisfy on clients that do not support video stream encryption, for example many mobile phones. If a client supports encryption for some video stream format(s), then the “best” of those formats should be selected. Here “best” is determined by the stream type priority algorithm.
The client capabilities are considered in determining an applicable streaming format in an embodiment. In considering client capabilities, the selection depends upon the supported video stream formats that include encryption, and the supported video stream formats that do not support encryption.
The device capabilities are considered in determining an applicable streaming format in an embodiment. In considering device capabilities, the selection depends upon the supported video stream formats that include encryption, the supported video stream formats that do not support encryption, and whether the device is on an encrypted private Wifi network managed by the gateway (in which case encryption at the network level is not required).
The network/system capabilities are considered in determining an applicable streaming format in an embodiment. In considering network/system capabilities, the selection depends upon characteristics of the network or system across which the stream must travel. The characteristics considered include, for example, the following: whether there is a gateway and/or server on the network to facilitate some of the fancier video streaming types or security requirements; whether the client is on the same LAN as the gateway, meaning that network firewall traversal is not needed.
Streaming methods with the highest priority are peer-to-peer because they scale best with server resources. Universal Plug and Play (UPnP) can be used by the gateway to open ports on the video stream device's LAN router and direct traffic through those ports to the video stream device. This allows a video stream client to talk directly with the video stream device or talk directly with the gateway which can in turn facilitate communication with the video stream device.
Another factor in determining the best video stream format to use is the success of STUN and TURN methods for establishing direct peer-to-peer UDP communication between the stream source device and the stream client. Again, the gateway and the server can help with the setup of this communication.
Client bandwidth availability and processing power are other factors in determining the best streaming methods. For example, due to its bandwidth overhead an encrypted MJPEG stream should not be considered for most mobile phone data networks.
Device bandwidth availability can also be considered in choosing the best video stream format. For example, consideration can be given to whether the upstream bandwidth capabilities of the typical residential DSL support two or more simultaneous MJPEG streams.
Components of the integrated security system of an embodiment, while considering various parameters in selecting a video streaming format to transfer video streams from streaming source devices and requesting client devices, prioritize streaming formats according to these parameters. The parameters considered in selecting a streaming format include, as described above, security requirements, client capabilities, device capabilities, and network/system capabilities. Components of the integrated security system of an embodiment select a video streaming format according to the following priority, but alternative embodiments can use other priorities.
The selected format is UPnP or peer-to-peer MPEG-4 over RTSP with encryption when both requesting client device and streaming source device support this format.

Additional detailed description of camera tunnel implementation details follow.
An embodiment uses XMPP for communication with a remote video camera as a lightweight (bandwidth) method for maintaining real-time communication with the remote camera. More specifically, the remote camera is located on another NAT (e.g., NAT traversal).
An embodiment comprises a method for including a remotely located camera in a home automation system. For example, using XMPP via cloud XMPP server to couple or connect camera to home automation system. This can be used with in-car cameras, cell phone cameras, and re-locatable cameras (e.g., dropped in the office, the hotel room, the neighbor's house, etc.).
Components of an embodiment are distributed so that any one can be offline while system continues to function (e.g., panel can be down while camera still up, motion detection from camera, video clip upload etc. continue to work.
Embodiments extend the PSIA in one or more of the following areas: wifi roaming configuration; video relay commands; wifi connectivity test; media tunnel for live video streaming in the context of a security system; motion notification mechanism and configuration (motion heartbeat) (e.g., helps with scalable server); XMPP for lightweight communication (helps with scalable server, reduced bandwidth, for maintaining persistent connection with a gateway); ping request sent over XMPP as health check mechanism; shared secret authentication bootstrapping process; asynchronous error status delivery by the camera for commands invoked by the gateway if the camera is responsible for delivering errors to the gateway in an asynchronous fashion (e.g., gateway requests a firmware update or a video clip upload).
Embodiments extend the home automation system to devices located on separate networks, and make them useable as general-purpose communication devices. These cameras can be placed in the office, vacation home, neighbor house, software can be put onto a cell phone, into a car, navigation system, etc.
Embodiments use a global device registry for enabling a device/camera to locate the server and home to which it is assigned.
Embodiments include methods for bootstrapping and re-bootstrapping of authentication credentials. The methods include activation key entry by installer into the cloud web interface. Activation key generation is based upon mac address and a shared secret between manufacturer and the service provider. Embodiments of the system allow activation of a camera with valid activation key that is not already provisioned in the global registry server.
Embodiments include a web-based interface for use in activating, configuring, remote firmware update, and re-configuring of a camera.
Embodiments process or locate local wifi access points and provide these as options during camera configuring and re-configuring. Embodiments generate and provide recommendations around choosing a best wifi access point based upon characteristics of the network (e.g., signal strength, error rates, interference, etc.). Embodiments include methods for testing and diagnosing issues with wifi and network access.
Embodiments include cameras able to perform this wifi test using only one physical network interface, an approach that enables the camera to dynamically change this physical interface from wired to wifi. Embodiments are able to change the network settings (wifi etc) remotely using the same process.
Cameras of an embodiment can be configured with multiple network preferences with priority order so that the camera can move between different locations and the camera can automatically find the best network to join (e.g., can have multiple ssid+bssid+password sets configured and prioritized).
Regarding firmware download, embodiments include a mechanism to monitor the status of the firmware update, provide feedback to the end user and improve overall quality of the system.
Embodiments use RTSP over SSL to a cloud media relay server to allow live video NAT traversal to a remote client (e.g., PC, cell phone, etc.) in a secure manner where the camera provides media session authentication credentials to the server. The camera initiates the SSL connection to the cloud and then acts as a RTSP server over this connection.
Embodiments include methods for using NAT traversal for connecting to the cloud for remote management and live video access allows the integrated security components to avoid port forwarding on the local router(s) and as a result maintain a more secure local network and a more secure camera since no ports are required to be open.
Embodiments enable camera sensors (e.g., motion, audio, heat, etc.) to serve as triggers to other actions in the automation system. The capture of video clips or snapshots from the camera is one such action, but the embodiments are not so limited.
A camera of an embodiment can be used by multiple systems.

More particularly, details follow of a camera interface specification (LWG CAMERA INTERFACE SPECIFICATION) in an example embodiment of the integrated security system described herein.
This document describes the communication protocol used between an iControl OpenHome-compatible Camera (OpenHome Camera) and the iControl Gateway. The OpenHome camera is an IP camera that supports the iControl OpenHome Camera Interface Specification and its associated requirements. The iControl Gateway is composed of several logical components—Registry Gateway, Credential Gateway, Premise Gateway (optional), and the Session Gateway. The OpenHome camera communicates with the iControl Gateway over IP networks (could be LAN or Internet) using standard network protocols such as HTTP/HTTPS, and XMPP (RFC 6120). In one deployment scenario, one or more OpenHome cameras are deployed at the customer premise in conjunction with a Premise Gateway, communicating with iControl Registry, Credential, and Session Gateways over the Internet (see
Henceforth in this document, the OpenHome-compatible camera is referred to as Camera. The iControl Session Gateway, is simply referred to as the Session Gateway, the iControl Registry Gateway, is referred to as the Registry Gateway, the iControl Premise Gateway is referred to as the Premise Gateway, and the iControl Credential Gateway is referred to as the Credential Gateway. Finally, the collective name for all three gateway logical components is referred to as the iControl Gateway.
Under this deployment scenario, the Camera and the Premise Gateway are deployed within the customer premise. The Local Bootstrap Procedures interface is used to discover and configure the Camera for subsequent accesses. The HTTPS Command/Notification interface is a bi-directional interface used by the Gateway to send Commands to the Camera or for the Camera to send Notifications to the Gateway. The Secure Streaming Media Channels interface is used to tunnel live RTSP or MJPEG streams from Camera to Gateway. The Media Upload Channels interface is used to upload video and image from Camera to Gateway. The HTTPS Notification interface is just a subset of the Command/Notification interface and is used by the Camera to post Notifications to the Gateway. An OpenHome camera when deployed in the Premise Gateway deployment scenario must support all four interface types described above.
Under this deployment scenario, the use of Premise Gateway within the customer premise is not required (but could optionally be deployed). The Off-Premise Bootstrap Procedures interface is used to discover and configure the Camera with siteID, shared secret, Session Gateway address, and other run-time parameters. The XMPP Command/Notification interface is a persistent bi-directional interface used by the Gateway to send Commands to the Camera or for the Camera to send Notifications to the Gateway. The Secure Streaming Media Channels interface is used to tunnel live RTSP or MJPEG streams from Camera to Gateway. The Media Upload Channels interface is used to upload video and image from Camera to Gateway. An OpenHome camera when deployed without an associated Premise Gateway must support all four interfaces described above.
Camera should support all mandatory features described in the iControl OpenHome Camera Requirements Matrix document. Furthermore, depending on the deployment mode supported, this document assumes the following parameters are pre-configured for each Camera:
Camera Prerequisites for On-Premise Gateway Deployment Mode
Camera Prerequisites for Off-Premise Gateway Deployment Mode
For deployment scenarios where WiFi repeaters are utilized or multiple WiFI APs shared the same SSID, a Camera shall periodically compare received signal strengths of all candidate AP/repeaters, and under the right conditions, re-establish connection to the WiFi AP/repeater with the best signal quality. General guidelines for this feature include:
The iControl Gateway (including Premise Gateway, Session Gateway, Credential Gateway, Registry Gateway, etc.) should support all mandatory resources/services required by the Camera in order process Commands or Notifications. For example, if a Gateway sends a Command to a Camera that includes mandatory URL for upload, notification, etc., the Gateway must support the specified services when accessed via the URL. At the same time, if a Gateway did not configure a Camera with an upload resource URL, the Camera cannot assume the upload service is available at the Gateway. For example, if no event trigger notifications are enabled at the Camera, the Camera cannot assume the upload Gateway resource will be available.
Each of the interface types above is described in more detail in the following subsections. The Local Bootstrap Procedures and the Off-Premise Bootstrap Procedures are described in Appendices A and B, respectively.
The Command/Notification channel is a bi-directional, asynchronous communication interface that allows for Gateway to send commands to the Camera or for Camera to send Notification Events to the Gateway. There are 2 sub-types of Interface Type 1—XMPP or HTTPS based Command/Notification Channel. The XMPP type, type 1A, uses XMPP as the underlying transport protocol, whereas the HTTPS type, type 1B, relies on HTTPS as the transport protocol. For most applications, only one of the two interface sub-types is required. Each of the two sub-types is described in more detail below. Henceforth in this document, Commands refer to Gateway originated commands from Gateway to Camera, and Notifications refer to Camera originated notifications from Camera to Gateway. Interface Type 1B can only be used if the Premise Gateway is deployed at the same premise as the Camera, whereas Interface Type 1A can be utilized independent of where the Premise Gateway is deployed.
The XMPP Command/Notification channel is a bi-directional, asynchronous communication interface that allows for Gateway to send commands to the Camera or for Camera to send Notification Events to the Gateway. This persistent channel is implemented using the XMPP protocol as described in RFC 6120 (Extensible Messaging and Presence Protocol: Core) as the underlying transport, and utilizing messages compliant with iControl's XML stanzas syntax to convey commands and notifications. The iControl XML stanza is a XML wrapper around HTTP-like request/response messages. Detailed definitions of Command and Notifications messages along with their parameters are described in later sections.
A typical channel establishment/disconnect process is described below:
The iControl Command/Notification Channel conforms to the XMPP standard with the following further clarifications:
Command and Notification request and response messages are sent using the following XML stanza schema:
This XML stanza schema allows HTTP-type requests and responses to be tunneled across a XMPP channel. <CommandURL> and <NotificationURL> are defined in the Command/Notification Data Types Section. The “method” attribute reflects HTTP methods such as GET, POST, PUT, DELETE, etc. and are defined by the specific <CommandURI> or <NotificationURI> types. HTTP request headers can vary among different Commands and Notifications; these headers can be enumerated using one or more “header” elements in the stanza.
The example below illustrates a Command from Gateway to set wireless configurations for the Camera's network interface 1. See Section 5.4.4 for URI and XML definitions.
The HTTP/HTTPS Command/Notification channel is a bi-directional, asynchronous communication interface that allows for Premise Gateway to send commands to the Camera or for Camera to send Notification Events to the Premise Gateway. The purpose of this interface is similar to the XMPP Command/Notification Channel sub-type, except the underlying transport protocol is HTTP/HTTPS instead of XMPP. Multiple messages can be sent over each connection due to the use of HTTP 1.1 persistent connection (RFC 2616). However, Unlike XMPP, HTTP/HTTPS (even with the use of HTTP 1.1 persistent option) may terminate a connection after an extended idle period. It is the responsibility of the initiating entity (either Camera or Premise Gateway) to re-establish a new connection when a new message is to be delivered. Detailed definitions of Command and Notifications messages along with their parameters are described in Section 5. This section describes the HTTPS transport used to send/receive these messages.
Commands are always send from Gateway to Camera via inbound HTTP/HTTPS connections to the Camera.
Notifications can be delivered from Camera to Gateway via either 1) Camera outbound HTTPS connection or 2) Camera inbound polling via the “/OpenHome/System/Poll/notifications” retrieval Command.
A typical Command/response process is described below:
Pre-Requisites:
Gateway Originated Command Channel Setup Process:
Camera Originated Outbound Notification Channel Setup Process:
Camera Notification Via Inbound Polling Process:
In lieu of using Outbound Notification Channel, Notifications can be delivered to Gateway via Inbound Polling. The following is a typical delivery process:
To issue a Gateway originated command, Gateway initiates HTTP/HTTPS connection to Camera via method and URI <CommandURI> specified by the Command (see Section 5 Command/Notification Data Types). HTTP 1.1 persistent connection mode should be utilized in order to optimize connection usage. Only accounts with administration rights can issue Commands the Camera, with the only exception being that User accounts can access video streaming and picture snapshot.
For Interface Type 1B (HTTPS Command/Notification Channel), Notifications can be delivered from Camera to Gateway via either 1) Camera outbound HTTPS connection or 2) Camera inbound polling via the “/OpenHome/System/Poll/notifications” retrieval Command (Note, the third delivery method, using XMPP Camera-to-Gateway channel, is utilized only in the XMPP Command/Notification Channel). Depending on the configuration of the notification URL parameter, the Camera delivers Notifications using one of the three methods above. For example, the following Notification URL specifies using the Camera outbound HTTPS Notification method:
https://gateway.icontrol.com/<eventAlertURL>
whereas, the following Notification URL specifies using Camera inbound polling for Notification delivery.
poll://<eventAlertURL>
Each of the two Notification delivery types is described in more detail below.
To initiate a Camera originated outbound Notification, Camera starts HTTP/HTTPS connection to Gateway via method and URI <NotificationURI> specified by the Notification (see Section 5). HTTP 1.1 persistent connections should be utilized in order to optimize connection usage. The following request format is used:
If specified in the Notification URL (e.g., poll://<url>), Camera will queue Notifications for retrieval by the Gateway instead of sending Notifications via outbound HTTP/HTTPS connections. The “/OpenHome/System/Poll/notifications” Command is used to establish a connection from Gateway to Camera for polling Notifications. In this mode, Gateway will establish a semi-persistent HTTP/HTTPS connection to the Camera and wait (or linger) for Notification events. Upon receiving the /OpenHome/System/Poll/notifications Command from the Gateway, if the Camera has Notification events available, it will respond with 200 OK containing Notifications right away. However, if no Notification is pending, the Camera will wait for a Notification or until the <linger> duration has expired before responding with 200 OK. Upon receiving a 200 OK response, the Gateway will issue another /OpenHome/Sytem/Poll/notifications Command to poll for new Notifications. Due to the use of HTTP 1.1 persistent connection, more than one request-response sequences may be sent over a single underlying TCP connection.
Gateway Originated Command
The example below illustrates a Command from Gateway to retrieve wireless configurations for the Camera's network interface 1. See Section 5.4.4 for URI and XML definitions.
Camera Originated Outbound Notification
The following example illustrates a Notification from Camera indicating a motion event.
Camera Notification Via Inbound Polling
The following example illustrates a motion event Notification from Camera that is delivered to the Gateway via inbound polling.
After 120 Seconds Without Notification
As Soon as Gateway Received and Processed the 200 OK Message
Three types of Streaming Media Channels are utilized for secured upload or live streaming of media contents from the Camera to the Gateway.
Each of these three types is described in more detail in subsequent sections. In addition to the three tunneled Media Channel modes, a Camera must also support direct, non-tunneled RTSP, HLS, or MJPEG connections initiated from RTSP/MJPEG/HLS clients. This mode may be used for direct client to camera access over a LAN without the use of an intervening Gateway.
The RTSP Media Channel is used to tunnel RTSP video over a TLS connection between the Camera and the Gateway. Upon receiving a Gateway originated Command (which is sent over the Command-Notification Channel), the Camera establishes a RTSP Media Channel connection to the Gateway via the following procedures:
The state transition diagram for the above sequence is illustrated in
See
Format of HTTPS POST URI from Camera to Gateway is described in more detail below. This request is sent from Camera to Gateway while transitioning from the SOCKET_CONNECTED state to the TUNNEL_READY state.
Camera should support RTSP per RFC 2326 (Real-Time Streaming Protocol) and RTP/RTCP per RFC 3550 (A Transport Protocol for Real-Time Applications). Furthermore, the following usage clarifications are to be followed:
The MJPEG Media Channel is used to tunnel MJPEG streams over a TLS connection between the Camera and the Gateway. The MJPEG Media Channel is very similar to the RTSP Media Channel, with the exception that MJPEG streams are transported over the tunnel and RTSP protocol is not used to negotiate a session. Upon receiving the /Streaming/MediaTunnel/create Command (which was sent over the Command-Notification Channel), the Camera establishes a MJPEG Media Channel connection to the Gateway via the following sequence:
The state transition diagram for the above sequence is illustrated in
MJPEG HTTP POST Tunnel Creation Format
Format of HTTPS POST URI from Camera to Gateway is the same the HTTPS POST request format in Section 4.2.1.3.
Format of HTTP GET URI from Gateway to Camera is described below:
The HTTP Live Streaming (HLS) Media Channel is used to tunnel HLS streams over a TLS connection between the Camera and the Gateway. The HLS Media Channel is very similar to the RTSP Media Channel, with the exception that HLS streams are transported over the tunnel and HLS request/response protocols are used to transfer media segments. Upon receiving the /Streaming/MediaTunnel/create Command (which was sent over the Command-Notification Channel), the Camera establishes a HLS Media Channel connection to the Gateway via the following sequence:
The Media Upload Channel is used to transport video clips, still frame images, or event notifications from the Camera to the Session Gateway. The Camera utilizes standard HTTPS POST procedures to transfer media content. All media upload channels must utilize secure TLS and digest authentication to encrypt and secure its content. Furthermore, Camera must utilize TLS host name verification while establishing secure connections. Media Upload Channels can be triggered by either a Gateway originated Command (e.g., CaptureVideoClip) or a Camera Originated event (e.g., motion detected, capture video and upload). Three types of Media Upload Channels are defined—1) Video Clip Upload, 2) Image Upload, and 3) event notification. The following subsections describe their specific formats.
Format of Video Clip HTTPS POST from Camera to Gateway is described below:
Format of Image HTTPS POST is described below:
Format of Event Notification HTTPS POST is described below:
If error is encountered during a Video or Image Upload procedure, the Camera is responsible for re-initiating the upload procedure up to <retries> times. Upon initial failure, the Camera should wait for a random delay between <minWait> and <stepsizeWait>. Each subsequent retry attempt should backup increasingly (preferably exponentially) using industry standard practices such as “truncated binary exponential backoff”, or using a multiple of <stepsizeWait>), up to maximum delay of <maxWait>. If Camera is still unable to upload media after <maxMediaUploadRetries>, Camera should send a MediaUploadFailure Notification event to the Gateway via HTTPS or XMPP Command/Notification Channel.
First connection retry wait time=random(0−<stepsizeWait>)
Subsequent retry wait time=max(<maxWait>, #reRetryCount*<stepsizeWait>)
The following tables list Commands and Notifications request and responses that can be transmitted over either the XMPP Command/Notification Channel or the HTTPS Command/Notification Channel. All Commands and Notifications requests should be responded to as soon as possible and the receiving device should not block the channel from receiving additional requests.
XML Data Blocks described in this document contains annotations that describe the properties of the field. For a complete definition, see the XML schema definitions. The following information is inserted into the comments to describe the data carried in the field:
Note that XML structures that are optional may have required fields. This means that the entire XML block is optional, however if it is present the required fields are mandatory.
Many data types defined in this chapter may be similar or have the same characteristics as defined by the Physical Security Interoperability Alliance (PSIA, http://www.psialliance.org). In particular, the PSIA Service Model (Pysical Security Interoperability Alliance Service Model version 1.0, revision 1.2) and the PSIA IPMD (Pysical Security Interoperability Alliance IP Media Device API Specification version 1.1, revision 1) documents define common terminologies and data structures used in this Section. However, new service commands and modifications were necessary to PSIA's model in order to support iControl's interface. The following tables summarize similarities and differences between the PSIA and the iControl data models. Columns marked as “Same as PSIA” are Commands that have same XML elements as PSIA, except for XML namespace. Columns marked as “Modified PSIA” are Commands that have similar XML elements as PSIA, but with iControl specific modifications. Columns marked as “New” are Command or Notifications specific to iControl.
Syntax for data type URIs defined in this Section is intended only as a recommendation. A Camera can override specific URIs for resources or add new URIs, if needed. Service discovery of OpenHome Data Type resources and their URLs can be achieved by retrieving (GET) from the following URI:
This version of the interface specification does not yet standardize on the resources' names. Future version of this document may define standard resource names in order to facilitate auto-discovery.
A list of Commands/Notifications and corresponding URIs are is described in the following subsections. The Type field in the table describes whether the URI is a Command or Notification, where a Command is a Gateway originated request and a Notification is a Camera originated request.
The ResponseStatus XML block is used throughout this Section. It is defined as:
ResponseStatus XML Block
For Commands that return with an error response, Camera should include <statusString> indicating reason for the failure. This response is particularly important when only a sub-portion of a configuration block encounters error; in such situations, Camera should respond with <statusString> indicating the elements and reason for the error.
Camera should respond with 4-Invalid Operation and set <statusString> to indicate the error, if any portion of the Command is not supported. For example, for a configuration Command, if a Camera supports most of the configuration but not all, Camera should return 4-Invalid Operation with <statusString> indicating which portion of the configuration parameters the Camera deems as not supported.
Camera configurations can be read or modified via HTTP/HTTPS access to URIs described in this Section. Unless explicitly specified, all configuration changes (if successful) should take effect immediately within the device before sending <ResponseStatus>. Only the following list of URIs can postpone effective status until after a device reboot:
For reach URI request above, the Camera should respond with “Reboot Required” in the <ResponseStatus> “statusCode” element.

Camera should support both client SSL certificates (used for validating Gateway identity) as well as server SSL certificates (used for Gateway to validate a camera's identity). One or more client SSL certificates are pre-configured in the Camera, but can be updated via the /OpenHome/Security/updateSSLCertificate/client Command. Server SSL certificate is used only if Interface Type 1B—HTTP/HTTPS Command/Notification Channel is activated, and it is usually not pre-configured at the device. Procedures for updating Camera's client SSL certificate is as follows:

Configuration for Motion Detection Alert
The example below illustrates a Command from Gateway to configure the camera to send PIR motion event Notifications to Gateway.
The example below illustrates a Notification from Camera to Gateway when a motion event is detected.
OpenHome Content Management can be used to control a Camera's DVR (Digital Vidoe Recorder) features. Functionalities such as local recording (scheduled or manual), searching, and playback of stored video “tracks” from the Camera can be accomplished via data types described here. Data types in this Section follow closely the PSIA Recording and Content Management Device Specification Version 1.1a, or RaCM Specification Version 1.1a. This document enumerates and clarifies the subset of the RaCM Specification used in OpenHome.
Local storage on the Camera can be managed in accordance to resources below:
A Camera may record/store one or more recording sessions, or “tracks”, in its local storage. “Tracks” are virtual containers. They may, or may not, correspond to a file, or set of files, etc. Basically, a “track” is a handle to specific type of multimedia information (e.g. video or audio) from a specific source. A “track” may contain parameters such as track id, recording method, track size, recording source description, codec type/bitrate/resolution, content type, custom extensions, etc. Furthermore, a track may contain a “schedule” that instructs a Camera to record at predetermined intervals. “Tracks” are managed via resources below:
Instead of using scheduled recording, a “track” (recording session) can also be controlled explicitly via external stimulus via the following resources:
Recording schedules can either be embedded within each track's configuration or can be configured for a Camera device. Recording schedules for a Camera can be managed using resources below:
Recorded tracks can be “searched” using resources described below:
Archived recordings are organized into “tracks”, each with unique IDs. One or more “tracks” can be streamed to Gateway/end-user or be uploaded to the Gateway via accessing resources below. Please note these resources are not intended for live video viewing; for live video, refer to /OpenHome/Streaming/Channels/ . . . .
Appendix A—Local Bootstrap Procedures
Local Bootstrap Procedures consist of 1) Camera discovery and 2) Camera configuration. Each step is described in more detail below:
Step 1—Camera Discovery
Camera discovery is achieved using UPnP's SSDP (Simple Service Discovery Protocol) process, where the Premise Gateway searches for one or more Cameras using the Camera's pre-configured USN (Unique Service Name). Camera must be pre-configured with a USN specified by iControl. Please refer to the UPnP specification (www.upnp.org) for a definition of the UPnP discovery procedure.
Step 2—Camera Configuration
If a Camera is discoverable via Step 1, and end-user/installer confirms intention to activate a specific Camera, the Premise Gateway will issue the following Commands via the HTTP/HTTPS Command Channel (see Section 4.1.2.1) to configure the Camera:
<ipAddress> is the Camera IP address discovered in Step 1. All Commands above require administrative account priviledges, therefore, the pre-configured administration account should be used to issue the above Commands.
Appendix B—Off-Premise Bootstrap Procedures
The Off-Premise Bootstrap procedures are used by the Camera to retrieve its siteID, shared secret, and remote Gateway addresses.
Using Step 1, Camera connects to the Registry Gateway (via the pre-configured Registry Gateway URL) and retrieves its assigned siteID and the Credential Gateway URL. Next, via Step 2, Camera retrieves its shared secret from the Credential Gateway using its siteID and Activation Key. Lastly, via Step 3, Camera retrieves Session Gateway Information from the Credential Gateway. At the end of the Bootstrap phase, the Camera will have obtained its secret credentials and its Session Gateway address from the iControl Gateway. Each of the Steps is describe in more detail below.
Bootstrap Procedure Frequency
Camera should perform bootsrap procedures upon EVERY device reboot. Upon statup, If SharedSecret is not set (e.g., brand new Camera, post factory reset), Camera should perform bootstrap Steps 1-3. Upon startup, if SharedSecret is already established (see Step 2), Camera should perform bootstrap Steps 1 and 3 only, and skip Step 2.
Step 1—Retrieve Gateway URL and SiteID
This procedure step is used by the Camera to retrieve its SiteID and Credential Gateway URL.
Step 2—Retrieve Credential
This procedure step is used by the Camera to retrieve its Pending Key. If SharedSecret is already established from previous successful Retreieve Credital procedure, this step should be skipped.
Pending Key→SharedSecret Retrieval Process
While Camera activation is underway, the Gateway will respond to a Camera's request for Credential with 200 OK containing the PendingPaidKey XML body (with method=“server”) with a pending key field. The pending key field will become active once the Camera connects to the Gateway over the XMPP channel and is authenticated using the pending key as its password. Once authenticated (via a successful XMPP session with the Gateway), the key is no longer pending and instead becomes active, or otherwise known as the Camera's <SharedSecret>. The active key (a.k.a, <SharedSecret>) will not automatically expire; however, the Gateway may update a Camera's <SharedSecret> using the SetKey command over the XMPP interface. Once a pending key becomes active, subsequent requests for the PendingDeviceKey will receive method=“retry” responses unless a new activation process is initiated (this can be done by administrators and installers via the iControl admin and portal applications).
If the Camera does not connect to the server over the XMPP channel and be authenticated using the key by the “expires” time specified in the PendingPaidKey XML body, then the pending key will expire and no longer be valid.
While Camera activation is underway, each request for the PendingPaidKey will receive a different key in the response, causing the previous pending key to be replaced with the new one.
It is expected that upon a factory reset, the device will forget its key and return to the bootstrap process of polling for a PendingDeviceKey.
Step 3—Retrieve Session Gateway Info
This procedure step is used by the Camera to retrieve Session Gateway Info, which includes XMPP Gateway address.
Appendix C—Activation Key Derivation Procedures
A Camera's activation key is derived from its serial number and a master secret. An activation key is 20 hex characters (0-f) long.
The first 10 characters of the activation key will be the last 10 characters of the serial number. The first 2 characters of the serial number will be derived from server configuration and will default to “00”.
A manufacturer-specific global code is now introduced which can be customer-specific and must be configured on the server. An example value for this will is “lw2jd3Dq”. This portion will be referred to as “globalCode” below.
The next 8 characters will be the first 8 characters of the MD5 hash of the following concatenation: globalCode+serialNumber.
The last 2 characters will be a CRC checksum of the first 18 in hex. The CRC8 checksum algorithm used should be “CRC-8-Dallas/Maxim x8+x5+x4+1 (1-Wire bus)”.
Activation key for 006035010057 will be 6035 0100 57ef 8c2a a6ba
Activation key for 006035000000 will be 6035 0000 0014 B08F C388
