Abstract

An intrusion detection system with a distributed sensor system coupled with a plurality of secondary sensors is disclosed. The distributed sensor is deployed over a protected zone, and detects physical disturbances caused by intrusion into the zone. A plurality of physical disturbing devices is coupled to the distributed sensor to physically disturb the distributed sensor. A plurality of secondary sensors is employed as additional sensors to volumetrically extend the sensing zone, and is coupled with physically disturbing devices. A secondary sensor sends a signal to an associated physically disturbing device upon detecting an event to be monitored, and the signal operates the physically disturbing device to produce a physical disturbance that will be detected by the distributed sensor. Location of the event is identified by analyzing the disturbance and consequently by locating the physically disturbing device and the associated secondary sensor.

Claims

1. An intrusion detection system comprising:

a distributed sensor system to detect physical disturbances caused by an intrusion over a distributed sensor of said distributed sensor system, said distributed sensor being deployed over a detection zone and producing a disturbance over said distributed sensor upon an intrusion;

a plurality of physically disturbing means for producing physical disturbances, coupled to said distributed sensor in a manner that each of said physically disturbing means disturbs said distributed sensor to produce a disturbance;

a plurality of secondary sensors deployed over a detection zone, each secondary sensor of said plurality of secondary sensors producing a signal in response to changes in a parameter being monitored by said secondary sensor; and

a linking means for transmitting signals produced by said secondary sensor to said physically disturbing means, said secondary sensor connected to at least one physically disturbing means of said plurality of physically disturbing means via said linking means.

2. The intrusion detection system of claim 1, wherein said distributed sensor system is intrinsically able to locate physical disturbances caused by an intrusion over said distributed sensor of said distributed sensor system.

3. The intrusion detection system of claim 1, further comprising a control station for detecting a disturbance and further processing said disturbance to detect and locate the intrusion.

4. The intrusion detection system of claim 1, wherein each of said physically disturbing means produces a characteristic physical disturbance that is identified at said distributed sensor system.

5. The intrusion detection system of claim 1, wherein each of said plurality of secondary sensors produces a characteristic signal, said characteristic signal being identified at least one of said plurality of physically disturbing means.

6. The intrusion detection system of claim 1, wherein said linking means is formed as a wired link.

7. The intrusion detection system of claim 1, wherein said linking means is formed as a wireless link.
