Overview: This product is a high stability infrared detector. Adopt advanced signal analysis and processing technology to provide ultra-high detection and anti-failure alarm. When an intruder passes through the detection area, the detector will detect the movement of the intruder by itself and send a wireless signal to the alarm host. The product is suitable for residential areas, villas, factories, warehouses, office buildings, etc. Features: Reliable Technology: Our motion detectors use state-of-the-art passive infrared (PIR) to detect any human motion within detection range. Overcome false positives. Multi-function: LED ON/OFF optional, delay adjustment, sensitivity adjustment, power saving mode/usage mode optional, code jumping, undervoltage indication. *Reliable Range: Communication range up to 100m/328ft (distance from sensor to receiver/alarm) and detection range of infrared sensor is about 8-12m/26-39ft, keep you informed and safe at all times. SMT design, high RFI/EMI immunity. Dynamic temperature compensation technical indicators: Working voltage: DC 9V Working current: 30mA Quiescent current: 20uA Detection distance: 12m (wide angle) Detection angle: 110 Launching distance: 100m (open area) Installation method: wall hanging PIR sensor battery: 1* 6F22 PP3 9V (not included) Item size (without stand): 11.2 * 6.2 * 4.5cm (L*W*H) Item Weight: Approx. 73g/2.6oz Packaging Information: Package Included: 1 * Wireless PIR Motion Sensor
