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.
