WebPIRs are basically made of a pyroelectric sensor (which you can see below as the round metal can with a rectangular crystal in the center), which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted. WebApr 14, 2024 · A PIR camera is thermal sensing and looks for changes in ambient temperature, but that doesn’t mean it will “see” a heat source such as a fire or a light bulb. It will detect infrared radiation either emitted or reflected from objects, so when shopping for a PIR camera, be sure it is labeled “heat sensing.”.
