How to hunt a camera?

Many people hear hunting cameras for the first time. Perhaps the first reaction is: How is it hunting?

In fact, hunting a camera does not launch bullets to hit the prey. Instead, it uses passive infrared radiation to capture the target photo or video for the hunter to track and monitor the prey. Currently, hunting cameras are widely used in outdoor hunting in Europe and America.

It is well known that animals and humans have infrared radiation. Infrared radiation is invisible to the naked eye, but infrared radiation can be detected by the PIR of the hunting camera. The passive infrared detector does not emit any energy. It only passively receives and detects infrared radiation from the environment. After the hunting camera enters the working mode, the PIR device works and the camera does not work only enters the standby state. Once the infrared radiation comes in, the PIR sensor generates a sudden electric signal through the optical system focusing, thereby starting the camera to take a photo or video.
