Installation Requirement:
1. Since the motion sensor alarm has much higher infrared detection sensitivity when human body moves laterally with respect to the lens, please pay attention to the angle and height of the detector horizontal plane during installation, which has a great influence on the zone.
2. During installation, please keep away from the hot and cold sources, such as hot and cold air outlet, air conditioning outlet, heater, air cooler, etc., to avoid direct door.
