What is a PIR detector? – PIR stands for passive infrared, and it’s also called PID for passive infrared detector. It’s an electronic sensor based on heat energy detection that is commonly used for PIR activated cameras, lights and alarms.
So a PIR sensor security camera is a camera packed with a PIR sensor, and based on it for motion detection. Sometimes, it’s also known as infrared motion sensor camera, PIR video camera, infrared motion detector camera or PIR sensor CCTV security camera.
To Know How PIR Security Cameras Work
How does a PIR sensor CCTV security camera work? – Unlike motion activated security cameras based on image comparison, passive infrared security cameras work by detecting changes in levels of infrared radiation.
PIR cameras will be triggered by the change in the infrared radiation, when humans or other warm-blooded creatures pass by.
