Abstract

Embodiments of intrusion detection systems are described and which include an intrusion detection panel that receives binary and metadata sensor data from which the presence of an alarm condition is detected. In addition sensor devices analyze sensor data received from other sensor devices that are in a peer to peer relationship with the corresponding sensor device to validate whether the indicated alarm condition is a valid alarm or a false alarm.

Claims

1. A system comprises:

a plurality of sensor devices including a first sensor device and a second sensor device, with each of the first sensor device and the second sensor device, comprising;

at least one event sensor element;

a processor device;

a memory in communication with the processor device; and

a storage device that stores a program of computing instructions to configure the processor device to;

receive sensor data from that sensor device'"'"'s at least one event sensor element;

analyze the received sensor data to detect the presence of an alarm condition;

the first sensor device further configured upon detecting the alarm condition, to;

broadcast by the first sensor device, the detected alarm condition to at least the second sensor device along with the sensor data received by the first sensor device, with the broadcast occurring over a peer to peer network;

receive by the processor device of the first sensor device from the second sensor device, results of an analysis by the second sensor device;

analyze by the processor device of the first sensor device, at least the detected alarm condition and the results from the second sensor device to validate whether the detected alarm condition is a valid alarm or a false alarm; and

raise an alarm when the results from the second sensor device confirm the presence of the detected alarm condition broadcasted from the first sensor device.

2. The system of claim 1, wherein the sensor data from the first sensor device is a binary signal.

3. The system of claim 1, wherein the sensor data from the first sensor device include metadata, with the metadata comprising information resulting from processing of inputs by the first sensor device with the information comprising data regarding a state of an environment within the range of the first sensor device.

4. The system of claim 1 wherein the system is an intrusion detection system and the instructions to analyze comprise instructions to:

determine whether there was an indication of a forced entry;

determine whether there was an indication of a perimeter presence using the metadata; and

determine whether there was an indication of a valid interior violation.

5. The system of claim 1, wherein the instructions further comprise instructions to:

maintain counts of and/or record details regarding false alarms asserted by the first and second sensor devices;

periodically send information including counts of asserted false alarms to a monitoring station.

6. The system of claim 1 wherein the second sensor device comprises:

the storage device that stores the program of computing instructions configured to cause the processor to;

receive the alarm condition and sensor data from the first sensor device that is in the peer to peer relationship with the second sensor device over the peer to peer network;

receive sensor data from the at least event sensor element of the second sensor device;

analyze the received sensor data from the at least one event sensor element of the second sensor device for the presence of the received alarm condition;

produce a composite filter declaration when the received alarm condition is validated by the analysis of the received sensor data from the second sensor device;

send the composite filter declaration.

7. The system of claim 6 wherein each sensor device further comprises:

a plurality of sensor elements, with the plurality of sensor elements producing the sensor data that are processed by the processor device; and

a network interface configured to communicate with other sensor devices in the peer to peer relationship with the sensor device.

8. The system of claim 7, wherein the sensor data includes metadata, with the metadata comprising information resulting from processing of inputs by the sensor device with the information comprising data regarding a state of an environment within the range of the sensor device.

9. The system of claim 6 wherein the instructions to analyze further comprises instructions to analyze the sensor data from the first sensor device and sensor data from the second sensor device according to order of arrival of the sensor data from the first sensor device and sensor data from the second sensor device.

10. The system of claim 6 wherein the second sensor device comprises plural sensor elements, and the instructions to analyze further comprise instructions to analyze the sensor data according to order of arrival of sensor data from the plural sensor elements.

11. The system of claim 10 wherein the sensor elements of the second sensor are contact switches and glass break sensors enhanced motion detectors, video cameras, microphones and/or other sound capturing devices.

12. The system of claim 6 wherein the first sensor device sends the composite filter declaration to a detection panel.

13. The system of claim 8, wherein the processor of the second sensor device is further configured to:

determine whether there was an indication of a forced entry;

determine whether there was an indication of a perimeter presence using the metadata; and

determine whether there was an indication of a valid interior violation.

14. The system of claim 7, wherein the sensor data is first sensor data, and the instructions to analyze comprise instructions to:

produce the composite filter declaration when analysis of the received second sensor data validates the presence of the indicated alarm condition.

15. The system of claim 13, further configured to:

process the metadata to assign a first one of a plural different levels of awareness, which is communicated to a monitoring station.
