PIR (passive infrared) sensors utilize the detection of infrared that is radiated from all objects that emit heat This article offers you information about how to adjust the PIR angle of your camera.
Applies to: Reolink battery-powered cameras.
The detecting distance of PIR motion sensors is 9 meters, and the detecting angle is 120˚ horizontally. Motions out of this range can’t be detected. Here is a suggested camera positioning.
Our PIR motion sensor is more sensitive to side-to-side movement than movement heading straight toward the camera. For example, when a person moves straight toward the camera (shown below), the PIR motion sensor will be less sensitive to the movement. Please make sure that the PIR sensor or the camera is installed in the direction crossing the possible intruder instead of facing it so that it can detect the motion more accurately.
