Overview:This product is a high stable infrared detector. It adopts advanced signal analysis processing technology, providing super-high detection and anti-fault alarm. When intruder passes through detection zone, the detector will detect the movemwnt of the intruder by itself, and emit wireless signal to alarm host. The product is suitable for housing estate, villa, factory, warehouse, office building, etc.Features:*Dependable technology: Our motion detector uses state-of-the-art passive-infrared (PIR) to detect any human movement within the detection zone. Overcome false alarm.*Multi-functional: LED ON/OFF optional, delayed adjustment, sensitivity adjustment, power saving mode/use mode optional, code skipping, under-voltage indication.*Reliable range: Communication range is up to 100m/328ft (the distance from the sensors to the receiver/alarm) and detection range of the infrared sensor is approximately 8-12m/26-39ft to keep you informed and safe.*SMT design, high RFI/EMI immunity. *Anti-burnt cover. Dynamic temperature compensation.Specifications:Working voltage: DC 9V Working current: 30mAStatic current: 20uA Detection distance: 12m (Wide angle)Detector angle: 110Emission distance: 100m (open area)Wireless frequency: 433MHzEncoded mode: 1527Installation Way: Wall HangingPIR Sensor battery: 1* 6F22 PP3 9V (not included) Item Size (Without Bracket): Approx. 11.2 * 6.2 * 4.5cm(L*W*H)Item Weight: Approx. 73g / 2.6ozPackage Information:Package Size: Approach. 14 * 8 * 5.5cm / 5.5 * 3.1 * 2.2in Package Weight: Approach. 115g / 4oz Package List:1 * Wireless PIR Motion Sensor1 * Bracket for PIR Sensor1 * Set of Mounting Screws1 * User Manual
