The detector is designed to protect open areas surrounded by metal (mesh) or reinforced concrete fence. Objects can be crane sites in the oil and gas industry, sites of television towers, etc.
The principle of operation is based on the creation between the receiver and transmitter invisible volumetric detection zone, the boundaries of which are determined by the size of the fenced area. When an intruder enters this zone, the detector registers its change and generates an alarm signal.
