In general, there has been an increased use of surveillance cameras and related systems. Not only has the extent of surveillance systems increased in traditional venues such as banks, the use of surveillance cameras has become more widespread throughout society. Most commercial entities, and many homeowners, employ some form of surveillance system for both external and internal monitoring.
A system and corresponding method, according to an embodiment of the present invention, provide a surveillance system, more specifically, a surveillance system with intelligently interchangeable cameras. An embodiment of the present invention includes multiple bases each having a respective base identifier. The system further includes cameras configured to be interchangeably coupled to the multiple bases. Within the system, a given camera is configured to learn a respective base identifier while in proximity with a given base and is further configured to employ a camera configuration corresponding to the respective base identifier.
An embodiment of the present invention further includes a system controller which has access to camera configuration information associated with the respective base identifiers. According to an embodiment of the invention, the system controller is communicatively coupled to the cameras and provides camera configuration information to the cameras. In another embodiment, the cameras are configured to transmit the learned base identifier to the system controller and, in response, receive camera configuration information that corresponds to the transmitted base identifier. In yet another embodiment, the cameras are configured to modify their respective camera configuration information to comply with the received camera configuration information. According to another embodiment of the invention, the cameras are communicatively coupled to the system controller and each camera is configured to transmit a signal to the system controller when a camera is removed from a base. In an embodiment of the present invention, the system controller is configured to generate a flag when the system controller receives a signal indicating a camera has been removed from a base.
Further embodiments provide for intelligent bases. According to one such embodiment, the system controller is communicatively coupled to the bases, and the bases are, in turn, configured to transmit a signal to the system controller, which indicates that a camera has been removed from the base. In yet another embodiment, the system controller is configured to generate a flag when it receives a signal indicating a camera has been removed from a base. Another embodiment of the present invention employs a system controller that creates a log of camera/base pairings within the surveillance system.
In an alternative embodiment of the present invention, the system controller is configured to transmit camera configuration information periodically to the cameras within the system. In such an embodiment, the cameras are configured to employ the corresponding camera configuration while in proximity with a base.
An embodiment of the present invention utilizes cameras configured to learn a respective base identifier while the cameras are mechanically coupled to a base. Further embodiments of the invention provide a surveillance system with more bases than cameras or more cameras than bases and, alternatively, a system where each camera can be mechanically coupled to every base. Other example embodiments include cameras that utilize battery power, and communicate control and data wirelessly.
Further embodiments provide for bases which store the respective base identifiers on a Radio Frequency Identification (RFID) tag coupled to each base, and the cameras can read the RFIDs wirelessly.
The foregoing will be apparent from the following more particular description of example embodiments of the invention, as illustrated in the accompanying drawings in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating embodiments of the present invention.
A description of example embodiments of the invention follows.
The increased use of surveillance systems has brought with it increased surveillance system complexity. Many surveillance systems include numerous cameras, each with corresponding software that allows the camera to operate with a particular camera configuration. A camera's configuration typically varies depending upon the placement of the camera, the role of the camera in the system, and also the overall goals of the surveillance system. Surveillance system setup and maintenance has become increasingly expensive and complex because of the vast size of surveillance systems and because of the labor needed to employ various camera configurations.
System maintenance has become correspondingly burdensome as well. After system setup, should a camera need to be replaced, the replacement camera needs to be particularly configured based upon where it is being placed within the system. This requires intervention by a party with both network and system configuration skills and knowledge. The complexity involved in camera replacement also yields downtime in data collection, leaving the system open to possible vulnerabilities.
The respective base identifiers 115a-n are each associated with a camera configuration. It should be noted that while each base 115a-n has an associated base identifier 115a-n, it is not necessary that the base identifiers 115a-n be unique. While unique identifiers may be advantageous, for example, so that camera/base pairings may be fully tracked and logged, a more simplistic system may utilize fewer unique base identifiers than corresponding bases. Such a system functions such that base identifiers are shared by bases where the same camera configuration is appropriate.
In an embodiment of the present invention, the above-described elements are configured to provide a surveillance system with intelligently interchangeable cameras. For example, in an embodiment, the system 100 has multiple bases 106a-n. Each base 106a-n has an associated base identifier 115a-n. Within the system 100, a given camera, such as the camera 105a, is configured to learn a base identifier, such as the base identifier 115a, when in proximity with the base 106a. After the camera 105a has learned the base identifier 115a, the camera 105a employs a camera configuration corresponding to the respective base identifier 115a.
According to an embodiment of the invention, the system controller 101 has access to the camera configuration information and the respective base identifiers. The system controller 101 may have access to this information from a storage device, such as the storage device 130 shown. The storage device 130 may be remotely or locally located with respect to the system controller 101. The storage device 130 may alternatively be within the system controller 101 or simply coupled thereto. The system controller 101 may be communicatively coupled to the cameras 105a-n. In an embodiment in which the cameras 105a-n are communicatively coupled to the system controller 101, the system controller 101 may provide respective camera configuration information, such as the camera configuration information 110a-n to the cameras 105a-n.
In an alternative embodiment of the invention, upon learning a respective base identifier, such as the base identifier 115a, the camera 105a may transmit the learned base identifier 115a to the system controller 101. After the system controller 101 has received the base identifier 115a, the system controller 101 may transmit the base identifier 115a, to the storage device 130. This is depicted in
An alternative embodiment of the invention uses a system controller, such as the system controller 101, that is configured to transmit camera configuration information 110a-n periodically to the cameras 105a-n. In an embodiment, the system controller 101 periodically transmits camera configuration information 110a-n, based upon received base identifiers 115a-n. Another embodiment operates without the transfer of base identifiers 115a-n to the system controller 101. In such an embodiment, the cameras, such as the cameras 105a-n, learn the respective base identifiers 115a-n, when in proximity with the respective bases 106a-n. The system controller, such as the system controller 101, periodically transmits camera configuration information; however, in this embodiment, the system controller transmits all of the possible camera configurations in the system 100 to the cameras 105a-n. The cameras 105a-n then only employ the camera configuration that corresponds with the respective learned base identifier 115a-n.
An alternative embodiment of the invention provides a surveillance system without a system controller. In such an embodiment, the cameras, such as the cameras 105a-n, have access to the all of the possible camera configurations in the system. In the embodiment where the cameras, such as the cameras 105a-n, have access to all of the camera configuration information, the cameras simply employ the respective camera configuration upon learning the respective base identifier when in proximity with a respective base.
In another embodiment of the present invention without a system controller, the bases, such as the bases 106a-n, each knows the respective camera configuration that a camera, such as the cameras 105a-n, should employ when in proximity with the bases 106a-n. In this embodiment, when a given camera is in proximity with a base, such as the base 106a, the base 106a transmits the appropriate camera configuration information to the camera, such as the camera 105a, and the camera 105a modifies its camera configuration to comply with the received camera configuration information.
Embodiments of the present invention also provide for system configuration information logging and tracking. This is accomplished by one such embodiment wherein the system controller 101 is communicatively coupled to the bases 106a-n. The bases 106a-n are, in turn, configured to transmit a signal to the system controller 101 when a camera, such as one of the cameras 105a-n, is removed from the bases 106a-n. According to yet another embodiment that provides for system configuration information logging and tracking, the system controller 101 is communicatively coupled to the cameras 105a-n and the cameras 105a-n are configured to transmit a signal to the system controller 101 when a given camera, such as the camera 105a, is removed from a given base, such as the base 106a. In response to receiving a signal that a camera has been removed from a base, the system controller 101 generates a flag indicating that a camera has been removed from a base. In yet another embodiment of the invention, the system controller 101 generates a log of camera/base pairings.
As described above, according to an embodiment of the invention, the cameras 105a-n are each configured to learn the respective base identifiers 115a-n while in proximity with the bases 106a-n. In an alternative embodiment of the invention, the cameras 105a-n are configured to learn the respective base identifiers 115a-n while mechanically coupled to the respective bases 106a-n. Such a system ensures that the cameras 105a-n learn only the appropriate base identifiers 115a-n. This functionality is particularly advantageous where bases are in close proximity to one another.
Another embodiment of the invention is a surveillance system with more bases than cameras or alternatively, more cameras than bases. In such an embodiment, the cameras can be coupled to all of the bases because each camera is configured to learn a respective base identifier and employ a camera configuration associated with the base identifier. Such a system is particularly advantageous where the cameras need to be swapped or moved often, such as with wireless or battery powered cameras.
The system controller 201 also includes a network interface 235 for receiving data, such as camera configuration information, and sending data, such as base identifiers, to and from storage devices, such as the storage device 230 via the network 240. Additionally, the network interface 235 may allow for communications with other system controllers (not shown), servers (not shown), computers (not shown), and any other points in or able to be connected to the network 240. The network 240 may be any such network that is known in the art, including, for example, a Local Area Network (LAN) or a Wide Area Network (WAN).
Further coupled to the system controller 201 is a camera/base interface 255. According to an embodiment of the invention, the system controller 201 communicates with cameras, such as the cameras 105a-n, through the camera/base interface 255. The system controller 201 may receive base identifier information via the camera/base interface 255. Further, the system controller 201 may communicate camera configuration information to cameras, either in response to a received base identifier or simply periodically, through the camera/base interface 255.
The camera 305 also comprises a controller 311. The controller 311 allows the camera 305 to employ a particular camera configuration. Further coupled to the camera 305 is memory 313. The memory 313 serves as volatile storage for instructions, base identifier information, and/or camera configuration information. The camera 305 also includes non-volatile storage 327, which may store instructions, base identifier information, and/or camera configuration information.
Further included in the camera 305 is a base identifier reader 323 for determining a base identifier when the camera 305 is in proximity with a given base. The base identifier reader 323 may be configured to determine a respective base identifier through any means known in the art, including mechanical, electrical, radio frequency, and optical methods.
The camera 305 further comprises a system controller interface 321. The system controller interface 321 permits the transmission and reception of data between the camera 305 and a system controller, such as the system control 201. The transmitted and received data may include base identifiers and camera configuration information. This data exchange may occur as described hereinabove in relation to
Finally, the camera 305 has a base interface 329. The base interface 329 allows the camera 305 to be coupled to a base, such as the base 106a (
The base 406 is configured to have an interface 431 that allows a camera, such as the camera 305, to be coupled to the base 406. The camera interface 431 may be configured to provide for the mechanical coupling of the base 406 to a camera.
