Passive Infrared (PIR)
Passive Infrared (PIR)
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 IP cameras, lights and alarms.
PIR Sensor
PIR sensor security camera is a camera packed with a PIR sensor, based on 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.
Accurate Detection
The PIR sensor surveillance camera working principle, to pick up motions that caused by people or animals, helps avoid false positives. Instead of moth flying videos, PIR video cameras will notify you of motion events that you should be alerted about.
