The article presents passive infrared (PIR) detectors used for the protection of large objects (buildings, airports, and border) or large areas having larger detection ranges and complex algorithms of signal analysis, upon which the efficiency of detectors' operation is significantly dependent. The construction and principle of operation of PIR detectors of a large detection range is presented. The article also presents the design and principle of operation of a PIR detector of a large detection range. The significant virtue of the described PIR detector is a highly efficient dectecion of very slowly moving or crawling people.
