PIR vs. IR Motion Sensors: Understanding the Key Differences

A construction worker in a hardhat is seen holding a camera, prepared to document his surroundings.

PIR (Passive Infrared) and IR (Infrared) motion sensors both detect movement, but they do so using different technologies. A PIR sensor detects changes in heat signatures, while an IR sensor emits infrared light and detects disruptions in its beam. Understanding these differences is crucial for choosing the right sensor for your specific security needs. Let’s […]
