The Mitsubishi Thermal Imager, model IR-5210A II was a state-of-the-art infrared camera system when made in 1989. Providing pictures of heat radiation at infrared wavelengths, such equipment has today found many applications, from fire detection to locating people in smoke filled buildings. The system uses a solid-state infrared detector array with 512 x 512 elements, which are cooled to -196 º C. In addition to the camera, there is a larger controller unit and a monitor to view the output.
