Wired Dual-tech Infrared Motion and Microwave Detector Wall Mounted PIR Motion Sensor Pet Immunity for Security Alarm System 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 movement signal, it is supplemented by microwave detection to determine whether the movement signal is real. It can avoid false alarm caused by outdoor 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 microwave detection technology can further suppress false alarms and improve detector sensitivity. The ABS housing is durable and has excellent shock resistance. Easy and quick to install. Note: Do not mount the unit in direct sunlight or near heat sources.
