ABSTRACT:
A method and apparatus for improving the sensitivity, angular resolution and range of motion detectors, occupancy sensors and similar systems are described. Specifically, an improved infrared input and detection section is described which utilizes two dual-detectors configured to optimally operate equivalent to a single quad-detector.
