Infrared radiation (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye.
Infrared radiation is used in industrial, commercial and inspection applications. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems and to detect overheating of electrical apparatus.
Infrared radiation is monitored to detect trends in the energy exchange (loss) between a home and its surroundings.
It also may be used to identify wet surfaces (which are typically colder) or leaks that are invisible behind wall surfaces (also colder or hotter).
