Overview: This product is a digital PIR+MW detector, exquisite design, easy installation. It contains digital processing software, which uses the infrared sensor as the main detection unit. When the infrared sensor detects the motion signal, it is supplemented by microwave detection to determine whether the motion signal is real. It can avoid false alarms caused by external interference, stable and reliable. Features: Excellent anti-false alarm and capture capabilities. Built-in temperature compensation and microwave anti-interference function, suitable for use in a variety of hot and cold environments. K-band micro-detection technology can also suppress false alarms and improve the sensitivity of the detector. The ABS housing is durable and has excellent impact resistance. Easy and quick to install. Note: Do not mount the device in direct sunlight or heat sources. Specifications: Voltage: 7.5V-16V DC / 25mA Detection Method: PIR + Microwave Detector Detector Range: 7.6mx7.6m
