WebbA thermographic camera (also called an infrared camera or thermal imaging camera, thermal camera or thermal imager) is a device that creates an image using infrared (IR) radiation, similar to a normal … WebbPassive infrared sensors (PIR). These motion sensor alarms sit with a bird’s eye view of the room and detect changes in the IR signature of a room over time. Active infrared sensors. Also known as tripwires, these emit an IR beam from one side of the room to the other, that detects an intruder when it gets interrupted.
