Introduction
1.2. Trail camera working principle
The trail camera is triggered by motion and variance in temperature.
The trail camera is able to do this by using a motion sensor. The PIR
sensor is aware that something is in front of them by changes in motion
and the temperature difference between the moving object and the
background environment.
The trail camera detects animals or people by sensing changes in
infrared light that occurs when the subject enters the camera's IR
detection zone: When the subject enters camera's IR detection zone, the
sensing module of the trail camera will start the camera to complete the
capture, thereby obtaining photos and videos. If the subject leaves the
detection zone, the trail camera is in a dormant standby state, for
example, the trail camera starts to capture again when it enters the
detection zone again.
Applications
■ Hunting: scouting an area for gaming
■ Wildlife observation at the backyard or garden: spying on the natural
world, indulging your interest in wildlife
■ Indoor/outdoor security surveillance
