1. Field of the Invention
The field of the invention relates to security systems generally, and more particularly to certain new and useful advances in guard communications of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same.
2. Description of Related Art
A mobile guard's awareness is often limited to what may be seen or heard while on a tour through an installation. For example, an emergency situation, such as a fire or an intruder on the other side of a wall, may not be discoverable while the guard is away from a central security console that has displays and sensor presentations. There is therefore a need for a way for a mobile guard to be made aware of visually and audibly blocked surroundings while on tour.
it is also desirable that there be a way to check that the guard did indeed visit appointed locations during certain time windows. There is therefore also a need for a way to verify that the mobile guard has properly completed appointed rounds.
Various embodiments of a method and system are disclosed that provide proximate environmental and security intelligence to a guard making a security tour or round in an installation. Also disclosed are various embodiments that include a provision for certifying that the guard has visited designated and known checkpoints on or about the times at which the guard is expected at those checkpoints and the provision of sensors and a channel from the guard back to a security station for reporting observed data.
Other features and advantages of the disclosure will become apparent by reference to the following description taken in connection with the accompanying drawings.
Reference is now made briefly to the accompanying drawings, in which:
FIG., 5 is a flowchart illustrating an embodiment of a method for communicating with the MSD;
Like reference characters designate identical or corresponding components and units throughout the several views, which are not to scale unless otherwise indicated.
In the exemplary embodiment, a security guard performing mobile rounds of an installation will carry a Mobile Security Device (“MSD”) that provides at least two functions: display of sensors about a guard's location together with data from those sensors, and certification, or evidence, that a guard visited one or more checkpoints.
The first function provides a display of sensors monitoring spaces proximate the guard's position as he or she progresses through a particular area. The sensors that are displayed on the guard's MSD may be fixed installation sensors that are linked with an installation's physical security system. The MSD may receive sensor data sent wirelessly from the central security console, or may query installation sensors directly when allowed by policy.
Features of the first function comprise, by way of example and not limitation:
(a) a visual display of one or more sensors in a proximate area (“spatial extent”) surrounding the guard's present position, and optionally—a visual and/or audible indication of sensor data for the one or more of the sensors;
(b) a visual display of one or more sensors in an area proximate the guard's scheduled route, and optionally—a visual and/or audible indication of sensor data for the one or more sensors; or
(c) a visual display of one or more sensors in an area proximate a path extrapolated from the guard's most recent direction of movement, and optionally—a visual and/or audible indication of sensor data for the one or more of the sensors.
The sensor data for which the MSD provides a visual and/or audible indication can comprise, but is not limited, to an alarm, such as a fire alarm, a smoke alarm, a door alarm, and so forth.
At least the sensor data for the display is sent to the MSD via a wireless transmission from a central security console that has access to the data from the one or more sensors that are proximate to the guard's present position, scheduled route, or the path extrapolated from the guard's most recent direction of movement. Map data for the display is also sent to the MSD via wireless transmission from the central security console or other network server. Alternatively, the map data for the display can be preloaded into a memory of the MSD.
In one embodiment, the map and/or sensor data is processed at the central security console and formatted so that its spatial extent is appropriate for the guard's position at the time of the guard's receiving the map and/or sensor data. The spatial extent may also be adjustable by either the guard or an operator of the central security console.
The spatial extent on the MSD display may be oriented with respect to the guard's most recent direction of motion or most recent orientation to provide a more natural and instantaneously unambiguous spatial reference to a mobile guard.
The second function provided by the MSD provides certification or evidence that the guard did indeed visit specified checkpoints, known to the guard, on or about time targets also known to the guard, during completion of the guard's appointed patrol.
in the exemplary embodiment, the evidence is provided by a scanning and recordation—or processed recordation—of an output of a fixed security device (“FSD”) at each checkpoint to be visited during a patrol. The FSD is anchored to structure near its location and is resistant to penetration and unauthorized opening. The FSD output comprises one or more informational elements, which comprise, but are not limited to:
a fixed security station identifier;
a time code; and
a certification informational element such as a symbol string.
The symbol string may change in a pseudorandom manner with a time code. An algorithm producing the value of the certification informational element may be a cryptographic process with a keying variable involving the security station identifier.
The FSD output may be electronic and communicated to the MSD by a near field communication (“NFC”) transmission. Other modes of communication between the FSD and the MSD may include acoustic, seismic (or vibration), optical (such as infrared, visible light, or ultra-violet), magnetic, and direct or capacitive electrical contact.
The central security console may determine the guard's present position, most recent direction of movement, and/or most recent orientation in at least two ways:
(a) the MSD contains onboard accelerometers, position sensors, and the like that output the MSD's location, most recent direction of movement, and/or most recent orientation for wireless transmission to the central security console; or
(b) alternatively, the MSD wirelessly transmits its present position, most recent direction of movement, and/or most recent orientation to the central security console. This may be accomplished using, by way of example and not limitation: accelerometers, radio or audio-based location techniques, and/or by calculation based on sensor imagery provided to the central security console whose processed outputs are formatted and/or overlaid with map data and/or sensor data, and then wirelessly sent from the central security console to the MSD for display.
Each of the high-level components comprises one or more sub-components. For example, the central security console comprises a user interface 107, a server 109, and an access controller 111. The user interface 107, which may be a keypad, a display and/or a computer mouse, is coupled with a server 109 and with one or more of the sensors 105. The one or more actuators 103 comprise a pan, tilt, and zoom actuator for a security camera and one or more door locks 115. The one or more sensors 105 comprise biometric identification device(s) 117, employee badge reader(s) 119, motion sensor(s) 121, security camera(s) 123, door contacts 125, and (optionally) one or more other sensors 127. The one or more other sensors 127 may include, without limitation: fire sensors, smoke detectors, microphones, keypads, and so forth.
The access controller 111 is coupled with the one or more actuators 103 and with the one or more sensors 105. In particular, the access controller 111 is coupled with the pan, tilt, and zoom motors 113 of a camera, and with one or more door locks 115. The access controller 111 is also coupled with, and configured to control, sensors 105 such as: motion sensor(s) 121, security camera(s) 123, and/or door contact(s) 125. Optionally, the access controller 111 may be coupled with, and configured to control, the biometric identification device(s) 117, the employee badge reader(s) 119, and/or the one or more other sensors 127.
Sensor data output from each of the sensors 105 is sent to the central security console 101 and stored in a database on the server 109 for later retrieval, processing, and/or transmission. Additionally or alternatively, each sensor stores sensor data in its memory, for later transmission to the database on the server 109 or for direct retrieval by the MSD 129. Examples of the sensor data output from each of the sensors 105 comprises, but is not limited to: when an event occurred, the type of event detected, and the sensor that made the detection. Simple sensors, such as the door contact(s) 125 or a fire/smoke detector may output limited data, such as that a door is open/closed or that fire/smoke has been detected. More complex sensors, such as the biometric identification device(s) 117 and/or the security camera(s) 123 may output more robust data that can be processed using known techniques to identify one or more persons (with a given probability) and/or to predict a probable individual and/or group behavior.
The processor 203 is coupled with a memory 205 and configured to process the map data, sensor location data and/or sensor data for display on the display 201. The processor 203 is further configured to operate the transceiver 207 to send and receive encrypted wireless messages to and from the server 109 (
Optionally, the processor 203 may be configured to operate and/or process data received from one or more onboard sensors 211, a locator 213, optics 215, a microphone 217 and/or a speaker 219. Examples of the one or more onboard sensors 211 comprise, without limitation: a temperature sensor, a gas sensor, a temperature gradient sensor, a humidity sensor, and so forth. For outdoor patrols of an installation, the locator 213 may be a global positioning system (“GPS”) receiver. For indoor patrols of an installation, the locator 213 is any device, or combination of devices, that outputs data, which the processor 203 and/or the server 109 (
The server 109 sends wireless messages 303 and/or 307 to the MSD 129, and receives wireless messages 305 and/or 309 from the MSD 129, over an encrypted wireless channel. In operation, the server 109 receives one or more first wireless messages 305 from the MSD 129, which comprise data indicative of, or which can be processed by the server 109 to calculate, the MSD's location, most recent direction of motion and/or most recent orientation. Thereafter, the server 109 transmits one or more second wireless messages 303 to the MSD 129, which comprise one or more of: map data, sensor location data, sensor data and/or orientation data. The sensor location data and/or sensor data is/are provided at least for the sensors 123 and 127 that are within, or overlapped by, the spatial extent 302. In order to transmit the one or more second wireless messages 303, the server 109 may compare at least the MSD location data and/or the MSD most recent direction of motion data with one or more previously stored lookup tables that contain sensor location data. The MSD processor 203 (
In an alternative embodiment, the server 109 calculates and transmits to the MSD 129, in one or more third wireless messages 307, one or more of MSD location data, MSD most recent direction of motion data, MSD most recent orientation data and sensor location data. Thereafter, the MSD processor 203 (
The view 460 depicts a sample front view of an exemplary MSD 129, which comprises, by way of example and not limitation, the display 201, input devices 209 (keypad and computer mouse), and optional camera 215, microphone 217 and speaker 219. On the display 201 is shown a map 480 of the area proximate the guard's/MSD's location, oriented to the MSD's most recent direction of motion and/or the MSD's most recent orientation, as represented by arrow 301. The map 480 depicts the MSD's location 470 relative to a location of the detected event 430. Optionally the display 201 depicts a location, and/or identification of an installation sensor 127
Proceeding from step 601, the method 600) may further comprise showing 607 on the MSD display 201 an indication of the location of the installation sensor 105, 127. Thereafter, the MSD 129 may receive 609 an input that selects the displayed installation sensor 105, 127. Upon receiving 609 this input, the MSD requests 611 sensor data for the selected installation sensor 105, 127 from the server 109 of the central security console 101. Thereafter, the MSD 129 receives 613 the requested sensor data, and may display 615 the received sensor data on the MSD display 201, together with a representation of the sensor's location—oriented with respect to the MSD's location, most recent direction of motion and/or most recent orientation.

Alternatively, the method 700 begins by a MSD 129 detecting 711 a presence of an installation sensor 105 proximate the MSD 129. From step 711, the method 700 comprises the MSD 129 receiving 713 a certification informational element from the detected installation sensor 105. From step 713, the method proceeds to previously described step 705.
