Abstract

Disclosed is an intruder alarm system comprising: an infrared camera set up to monitor a predetermined area of interest; a video analysis module in communication with the infrared camera, the video analysis module for providing video analysis of at least one of a plurality of video frames received from the infrared camera; and an alarm signal module for generating an alarm signal in response to intruder activity indicated by the video analysis module.

Claims

1. An intruder alarm system comprising:

an infrared camera monitoring a predetermined area of interest and providing a video transmission signal including a plurality of video frames to a remote monitoring facility;

a video analysis module in communication with said infrared camera, said video analysis module for providing video analysis of at least one of a plurality of said video frames provided by said infrared camera; and

an alarm signal module for generating an alarm signal in response to intruder activity indicated in a predefined “

no go”

zone by said video analysis module, said alarm signal received at said remote monitoring facility at the same time as a corresponding video transmission signal.

2. The intruder alarm system according to claim 1 wherein said infrared camera is responsive to thermal emissions indicative of human body temperature.

3. The alarm system according to claim 1 wherein said infrared camera is responsive to remotely generated control signals.

4. The alarm system according to claim 3 wherein said alarm signal module functions to generate said alarm signal in response to detection by said video analysis module of at least one contrasting image or a newly-appearing pattern in said at least one of said plurality of video frames.

5. The alarm system according to claim 1 wherein said alarm signal is transmitted to said remote monitoring facility over at least one of a wired network, a wireless cellular network, a public switched telephone network, and a virtual private network.

6. The alarm system according to claim 5 wherein said alarm signal comprises dual-tone multi-frequency tones.

7. The alarm system according to claim 1 further comprising a control room format module for formatting said alarm signal.

8. The alarm system according to claim 7 wherein said control room format module functions in accordance with at least one of 3+1, 4+1 Standard and Extended, Acron Touchtone, ADEMCO Contact ID, ADEMCO Express, ADEMCO High Speed, BFSK, FBII 4+3+1, ITI CareTaker+, SecurityPro 4000, ITI Commander, ITI Commander 2000, LifeGard, ITI RF Commander, Harbor Gard, ITI SX-V, ITI UltraGard, Modem II, Modem IIe, SK 4+2, SK FSK, Radionics 3+1 Checksum, Sescoa 3+1/Franklin 3+1, SIA DCS, SK 3+1/3+1 Extended, SX-III, SX-IVA, SX-IVB, Varitech FSK 4/1, 4/2 Westec.

9. The alarm system according to claim 1 further comprising a video compression module for compressing said plurality of video frames into a compressed video signal stream.

10. The alarm system according to claim 9 further comprising an IP packetization module for converting said compressed video signal stream into a video IP signal stream.

11. The alarm system according to claim 10 wherein said video IP signal stream is transmitted to a remote monitoring facility over a 10/100/1000 Ethernet network.

12. The alarm system according to claim 10 wherein said IP packetization module operates in accordance with any of ANSI Standards RS-422, RS-485, or RS-232.

13. A method for infrared monitoring of a predetermined area of interest, said method comprising the steps of:

setting up an infrared camera having a field of view including the predetermined area of interest;

transmitting a video transmission signal including a plurality of video frames from said infrared camera to a video analysis module and to a remote monitoring facility;

analyzing video images in said plurality of video frames with said video analysis module;

if said video analysis module provides an indication of the presence of an intruder in a predefined “

no go”

zone, generating an alarm signal in response to said indication, said alarm signal received at said remote monitoring facility at the same time as a corresponding said video transmission signal.

14. The method according to claim 13 wherein said step of setting up comprises the step of remotely controlling said infrared camera via a communication network.

15. The method according to claim 13 wherein said step of analyzing said video images comprises the step of detecting the appearance of at least one contrasting image in said plurality of video frames.

16. The method according to claim 13 further comprising the step of transmitting said alarm signal to said remote monitoring facility.

17. The method according to claim 13 wherein said alarm signal comprises dual-tone multi-frequency tones.

18. The method according to claim 13 wherein said alarm signal comprises a signal formatted in accordance with at least one of:

3+1, 4+1 Standard and Extended, Acron Touchtone, ADEMCO Contact ID, ADEMCO Express, ADEMCO High Speed, BFSK, FBII 4+3+1, ITI CareTaker+, SecurityPro 4000, ITI Commander, ITI Commander 2000, LifeGard, ITI RF Commander, Harbor Gard, ITI SX-V, ITI UltraGard, Modem II, Modem IIe, SK 4+2, SK FSK, Radionics 3+1 Checksum, Sescoa 3+1/Franklin 3+1, SIA DCS, SK 3+1/3+1 Extended, SX-III, SX-IVA, SX-IVB, Varitech FSK 4/1, 4/2 Westec.

19. The method according to claim 13 further comprising the step of sending said plurality of video frames to a remote monitoring facility.

20. The method according to claim 19 further comprising the step of formatting said video frames in accordance with any of ANSI Standards RS-422, RS-485, or RS-232 for transmission over a 10/100/1000 Ethernet network.
