Infrared surveillance cameras are now widely used for field animal surveys and monitoring. What is the principle of infrared surveillance cameras?
The principle of the infrared monitoring camera is mainly to detect the heat change in the sensing range by the PIR sensor, and then send a signal to the master to take a picture to obtain a photo or video. If the heating body (animal, etc.) leaves the PIR sensing range, the infrared monitoring camera Will immediately enter the sleep standby state, such as when entering the infrared sensing range again, the infrared monitoring camera starts again to shoot.
