Tihebeyan Wireless Home Security Alarm Motion Detector System Alarm Siren 105DB 105 Wide Angle PIR Motion Sensor Detectors Door Window Home Security System

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 protection 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. 3. The detection area can not have obstacles. 4. The angle between motion sensor alarm the wall should be10 to 30 degrees. At this point, the detection distance is farthest. Instructions: 1. The standby time is 20 seconds after power on and the motion sensor alarm will not detect signal within the 20 seconds, so you must leave the electronic leave detection area within 20s. 2. 20 seconds later, if a person enters the detection area, the motion sensor alarm will have a delay of 5 seconds. This will facilitate the identification of the owner. After 5 seconds, if no correct password is received, there will be a alarm sound of 30 seconds. The alarm volume is 105 DB. 5 seconds after the alarm sound is over, if another person comes into the detection area, it will alarm again and again. 3. During alarm, you can enter the correct password to end the alarm.
