Of approximately 0.75–1.4 μm, which is just beyond visible light, is called near-infrared light (NIR). Infrared radiation light with wavelengths The infrared spectral region is divided into several subregions. Radiation is not visible to the human eye, however a different type of sensor technology allows theĬamera to visualize the thermal image in the visual spectrum. To detect radiation with greater wavelengths, that is called thermal or infrared radiation. Thermal cameras, on the other hand, are designed Range of visible light is approximately 0.38–0.78 μm. Traditional images are produced when visible light is reflected off different objects. See Section 5, Useful links, ‘Some like it hot – Thermal cameras in surveillance’, for more information on In public services such as firefighting and law enforcement. In such diverse industries as the aircraft and shipping industry, within security and surveillance, and also Thermal imaging is becoming increasingly more available as new sensors, new materials and improvedĬalibration make thermal cameras more affordable, reliable and versatile. Unlike ordinary temperature sensors that only measure at one specific point, Axis temperature alarmĬameras can be used for remotely monitored surveillance, giving visually conformation of events at the Axis temperature alarm cameras make it possible to monitor the temperature of an object or an industrial process so that it does not rise above or fall below a certain temperature limit, in order to prevent
