Motion sensor evaluation using simulation

Thorough evaluation testing of interior motion sensors which requires repeated testing under a variety of environmental conditions is outlined. Although the sensors are intended primarily for interior installations, many of the buildings where protection may be required are warehouses or bunkers without environmental control. To evaluate sensors for such installations, it is important to collect data on coverage or sensitivity at room temperature and at environmental extremes. A system designed and built to provide repeatability in environmental testing is described. The system is dubbed sandia intruder motion simulator (SIMS). This system is used to acquire much of the data now collected on sensors in the laboratory and a duplicate system has been delivered to the Belvoir R and D center so that the laboratory can now run similar tests.
