How Do Infrared Cameras Work?

An infrared camera detects the thermal energy or heat emitted by the scene being observed and converts it into an electronic signal. This signal is then processed to produce an image. The heat captured by an infrared camera can be measured with a high degree of precision.

Infrared Technology

An infrared camera also has infrared light-emitting diode (LED) lights positioned on the outside of the camera, around the lens. These act as a spotlight to help illuminate the images you want the camera to capture. The more LEDs the camera has built-in, the further away the camera can see.
