Wireless motion sensor alarm, a complete alarm system based on independent motion sensors, suitable for sheds, kitchens, rooms, boats, garages, etc. It provides additional security for your property and loved ones. * Precautions: 1. Try to avoid installing the sensor in a position directly facing the large air flow and close to the heat source. (Such as: cold air outlet, exhaust fan, electric furnace or nearby heating, etc.). Do not install the sensor directly in the sun and rain, or close to metal objects. 2. The sensor should be installed at a height of about 2 meters; the horizontal detection of the sensor is more sensitive than the detection of a straight line (the human body faces the sensor directly). Generally, it should be installed on the side or top of the entrance gate, and the sensor should be adjusted to a suitable position through the installation bracket, in order to achieve a good induction effect. 3. The interference between obstacles and other wireless signals should be minimized between the sensor and the receiver. Generally, under the obstruction of a wall, the distance between the sensor and the receiver should be controlled at about 20 meters. 4. If the doorbell has a short receiving distance or malfunctions, please check the detector battery or replace it. 5. If the ambient temperature is too high (over 30 ℃), the sensing distance of the detector will be shortened, which is a normal phenomenon.
