"If the PIR is accidentally triggered, there may be objects in the motion detection area that can easily set off the alarm, such as an air conditioner running or a car. Solution: 1. it is recommended not to install the camera on the side of the road or in crowded scenes. 2. try not to point the camera at a heat source similar to the outdoor unit of the air conditioner to avoid accidental triggering. 3. adjust the sensitivity of the motion detection and reduce the motion detection range of the camera. 4. the alarm schedule can be adjusted and the time period of the camera alarm can be divided reasonably."
