Paper Abstract

A passive intrusion detector has been developed which detects personnel, vehicles and other targets by means of the infrared radiation they emit. In its basic form, the in-strument monitors two side-by-side fields of view, and a target-to-background contrast of 0.1°C (or correspondingly more for targets smaller than the full field of view) actuates the system. Intrusion can be indicated by audio and visual alarm outputs. This paper will described several narrow field passive infrared intrusion detectors .
