Overview: This product is a digital PIR+MW detector with an exquisite design and easy installation. It incorporates digital processing software that uses an infrared sensor as the main detection unit. When the infrared sensor detects a motion signal, it is supplemented by microwave detection to determine whether the motion signal is genuine. It can avoid false alarms caused by external interference and is stable and reliable. Features: Excellent anti-false alarm and detection capabilities. Built-in temperature compensation and microwave anti-interference function, suitable for use in a variety of hot and cold environments. The Micro K-Band 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 installation. Note: Do not mount the device in direct sunlight or away from heat sources. Features: Voltage: 7.5V-16V DC / 25mA Detection Method: PIR + Microwave Detector
