A thermal imaging camera is a device that is designed to capture and display heat radiation from objects and surfaces. There are several synonyms for thermal imaging camera, including thermal camera, infrared camera, and thermographic camera. These devices are commonly used in applications such as firefighting, industrial maintenance, and medical diagnosis. A thermal camera is an essential tool for firefighters to see through smoke and find people in a burning building. In industrial applications, thermographic cameras can identify hot spots in electrical systems, machinery, and building envelopes. In medical diagnosis, infrared cameras can detect abnormal temperature patterns in the body, which can indicate inflammation or disease.
