Their small size and accurate detection make them suitable for the activation of video transmission systems and the positioning of pan and tilt and dome cameras.
They can also be used on manned CCTV system to alert an operator’s attention to movement in a specific area. The detectors are single ended devices and do not emit or transmit signals.
Detection is achieved by monitoring far infrared levels between an intruder and the background in the detector’s multiple fields of view. The detectors use twin dual element sensors and twin electronic processors to achieve detection while maintaining operation stability. A precision optical array, combining reflective and refractive lenses, provides the sensors with a precise coverage pattern that can be accurately aligned using the LRP 1020 Audio Walk Tester.
