Infrared Beam Sensor, 1 Pair Single Photoelectric Detector Active IR Alarm Host for Security System Waterproof

ADVANCED TECHNOLOGY: Design with waterproof cover,all-weather integrated structure design of fully sealed waterproof (fog), dust proof (insect),etc.Enables it to work normally in harsh environment. UNIQUE DESIGH: High-power transmitter, 90% sensitivity margin, high-power infrared transmitter-receiver pair tube, low-power processing technology lightning protection circuit design.High level of anti RFI/EMI capability and unique digital filter circuit design. ACTIVE REGULATION: Resistant to strong light up to 50,000 LUX, built-in automatic adjustment of strong light filter system, to avoid the impact of strong light or car lights.Moreover, the detector will automatically enhance sensitivity when encountering heavy fog or bad weather.(AGC circuit) WIDE APPLICABILITY: Active infrared detector can replace the passive infrared intrusion detector installed in small supermarkets, convenience stores, visitors import and export, window entrance protection, but also applicable to schools, office buildings, dormitories, home courtyards and other security systems. INSTALLATION: The best installation height should be more than 2Ocm, installation distance should be not less than 1 m; infrared protection device should be vertically placed, and in the same horizontal line.First, please install the receiver, then the transmitter(when in a straight line, OFF light of receiver goes out), then fix,connect line and complete installatio.
