Patent ID: 7154391

Claim:
A sensor array forming part of an intrusion detection system and having a plurality of discrete volumetric sensors each having an associated volumetric intrusion detection field extending therefrom and constructed and arranged to generate a response to an intruder entering its detection field, the sensor array comprising: a deformable cable; a plurality of sensor nodes situated and spaced along the deformable cable, each sensor node having at least one discrete volumetric sensor having a detection field and at least one of the sensor nodes having at least two discrete volumetric sensors, each sensor node having a volumetric detection zone defined by the detection fields of its constituent sensors as constructed and arranged in each sensor node, the volumetric detection zone extending transversely to the longitudinal direction of the deformable cable at the sensor node; and a plurality of node processors, each corresponding to one of the plurality of sensor nodes and situated thereat, for generating information based on processing of the response generated from the detection zone of the constituent sensors.
