Abstract

The article presents passive infrared detectors (PIR) used for protection of large objects (buildings, airports, border) or large areas have larger detection ranges and complex algorithms of signal analysis, on which significantly depends efficiency of detectors operation. The construction and principle of operation of passive IR detectors (PIR detectors) of a large detection range is presented. The paper presents design and principle of operation of a passive IR detector of large detection range. Significant virtue of the described PIR detector is highly efficient detection of very slowly moving or crawling people. Keywords: passive infrared detector, security systems, probability of detection.
