" Overview: This product is a high stable infrared detector. It adopts advanced signal analysis processing technology, providing ultra-high detection and anti-fault alarm. When an intruder passes through the detection zone, the detector detects the movement of the intruder by itself, and transmits the wireless signal to the alarm server. The product is suitable for subdivision, villa, factory, warehouse, office building, etc. features: * Dependable Technology: Our motion detector uses state-of-the-art-passive infrared (PIR) technology to detect any human movement in the detection area. Overcome false alarm. * Multi-functional: LED ON / OFF Optional setting, delayed, sensitivity setting, energy saving mode / optional operating mode, code to skip, power on indication. * Reliable range: Communication range is up to 100m / 328ft (the distance between the sensors to the receiver / alarm) and the detection range of the infrared sensor is about 8-12m / 26-39ft to keep you informed and safely. * SMT design, high RFI / EMI immunity. * Anti-burn blanket. dynamic temperature compensation. Characteristics: Operating voltage: DC 9V Operating current: ≤30mA Static current: ≤20uA Detection distance: 12m (wide angle) detector angle: 110 ° C the transmission distance: ≥100m (open area) Wireless frequency: 433MHz Coder mode: 1527 Installation way: Wall hanging PIR sensor battery: 1 * 6F22 PP3 9V (not included) Item size (without stand): approx. 11.2 * 6.2 * 4.5cm (L * W * H) Item weight: approx. 73g / 2.6oz Information package: Package size: approach. 14 * 8 * 5.5cm / 5.5 * 3.1 * 2.2in Package weight: approach. 115g / 4oz List of packages: 1 * PIR wireless motion detector 1 * Support for PIR sensor 1 * Set of mounting screws 1 * User Manual "
