Abstract
An intrusion detection system comprises a plurality of sensors and a corresponding plurality of receivers, each receiver coupled to receive via the associated sensor radio frequency signals having a multiplicity of transmissions at different frequencies within a predetermined frequency spectrum. The receiver detects the radio frequency signals and computes for each of a plurality of successive time intervals and for each of the transmission frequencies measurement of signal amplitude over the time interval; compares such signal amplitude measurement with at least one threshold and, if the amplitude exceeds the threshold for a predetermined time period, generates a potential alarm conidtion. A common processor monitors the potential alarm conditions for the plurality of receivers and provides an actual alarm signal when at least one of the receivers indicates potential alarm conditions for a predetermined number of the different transmission frequencies within the same time period. Preferably, the processor compares potential alarm signals from a plurality of sensors and determines that an intrusion has occurred if the potential alarm signal for a particular station does not coincide with a potential alarm signal for a neighbouring sensor. Each receiver may compare potential alarm signals for a plurality of the transmission frequencies and output an intruder alarm signal when potential alarm signals occur simultaneously for more than a preset number of the multiplicity of transmission frequencies.
