Abstract
A study was conducted to assess the capabilities of an exterior passive infrared (PIR) intrusion detection sensor. The study involved a series of field tests and the development of a sensor performance model. This paper describes the model and presents examples of model output. System sensitivity to changes in target and background surface temperatures, target size, target range, and target speed are shown. The PIR model should prove useful as an aid in determining the proper configuration of such sensors within a fixed-facility or tactical surveillance application.
