Abstract
An improved IR detector system is described which uses a plurality of IR detection modules coupled to a central computer to determine the location of an intrusion to the system. Each IR detection module has a plurality of optically isolated lens and detector pairs arranged in an arcuate array coupled to a local microprocessor chip which is unique to that module such that each lens and detector pair produces a response to a sensed intrusion along a particular radial of the array's arc to allow the local microprocessor to produce a coded signal to the central computer which corresponds to the direction of the sensed intrusion. Using a triangulation algorithm, the central computer combines the coded signals from whichever of the plurality of IR detection modules are active to compute the location of the intrusion.
