Wireless Dual-Tech Detector is an indoor detector that detects human motion. Using passive IR and microware detection technologies, the device detects the movement of persons and senses when they have entered the detection area. Through these technologies, false detections caused by thermal interference are also greatly reduced. The device is easy to install and use, and can be directly configured on the app.

· Pet immunity function.

· Auto temperature compensation.

· 3-level sensitivity adjustment.

· Displays the temperature of the surrounding environment and supports the overheating alarm.

· Frequency hopping and two-way communication technology ensure that communication is stable.

· Supports cloud update and automatically restores when cloud update fails.

· PIR and microwave motion detection.

· Supports jamming detection and communication encryption.
