An IR thermal camera is a device that uses infrared radiation to capture thermal images and videos of objects and environments. It can detect the temperature of objects and display them as a color image or video. IR thermal cameras use a special lens to focus infrared radiation onto a sensor that produces an electronic signal based on the intensity of the radiation. The signal is then processed to create a thermal image or video. IR thermal cameras have various applications, including medical diagnosis, building inspection, firefighting, and surveillance. They are also used in the automotive industry to detect overheating components and in home energy audits to identify areas of heat loss. IR thermal cameras are highly sensitive and can detect temperature differences as small as 0.01C, making them a powerful tool for identifying potential problems before they become major issues. An IR thermal cameras provide a non-invasive and highly accurate method of measuring temperature and have numerous practical applications in a variety of industries.
