Understand the Detecting Field of the PIR Motion Sensor
The PIR motion sensor is more sensitive to side-to-side movement than
movement heading straight toward the camera or away from the detection
area of the PIR motion sensor.
For example, when a person moves straight toward the camera, the PIR
motion sensor will be less sensitive to the movement.
Note: To get the best performance of the camera, please make sure the
camera is mounted well within the coverage of your wireless network.
Camera Placement Dos & Don'ts
For reducing False alarms, please note that :
● Do not install the camera facing any objects with bright lights, including
sunlight and bright lamp lights.
● Do not place the camera too close to a place where many vehicles move
frequently; 15 meters away from the vehicle is the recommended distance
based on our numerous tests.
● Stay away from the outlets, including the air conditioner vents, humidifier
outlets, the heat transfer vent of projectors, etc.
● Do not install the camera facing the mirror/glass.
● Keep the camera at least 1 meter away from any wireless devices, including
Wi-Fi routers and phones in order to avoid wireless interference.
