Meiantech professional security system focus brand wireless alarm systems. DT-81R is PIR intrusion detector with pet immunity function. It adopts DMT and it is a digit micro processing control intrusion detector.
It adopt dual technology PIR and MW to avoide falase alarm. With fine cylindrical FRESNEL lens, it effectively improves energy saving
efficiency and high sensitivity and free of false alarm. By using advanced patented software,it can tell difference between the real intruder and other interference factor which may result in false alarm. It has super strong detection sensitivity and lower false alarm. Pulse counting can be adjustable.
Dual technology MW&PIR, dual-processor improves the ability of signal processing.
Selectable pulse count, Auto Temp. compensation and energy analysis.
Excellent white light prevention with white light protection lens and optics protection cover.
Advanced pet-immunity recognition can tell the difference between a intruder and a pet.
Excellent false alarm prevention with look-down window to avoid blind-corner.
Reliable performance with tamper supervised, low-voltage check and status report function.
