Abstract

An apparatus, system and method for electronic motion detection are disclosed. Passive infrared sensor clusters are mounted in spaced, forward facing positions within a housing and include a left binocular plurality of passive infrared sensors and a right binocular plurality of passive infrared sensors. These passive infrared sensor clusters define respective left and right overlapping fields of view having the same horizontal elevation with a horizontal spacing being adjustable therebetween. Detection circuitry processes respective detection signals relative to an intruder received from the left and right binocular plurality of passive infrared sensors to eliminate false positive signals and classify the intruder as one of moving left to right, right to left, and stationary.
