2009
Safety and Security Engineering III
unpublished
Preserved Fulltext
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
