Thermographic camera - Wikipedia
A thermographic camera (also called an infrared camera or thermal imaging camera or thermal imager) is a device that creates an image using infrared radiation, similar to a common camera that forms an image using visible light.Instead of the 400–700 nanometre range of the visible light camera, infrared cameras are sensitive to wavelengths from about 1,000 nm (1 μm) to about 14,000 nm (14 μm).
