An infrared camera is a device that captures images using infrared radiation, which is not visible to the human eye. These cameras detect heat emitted by objects, allowing them to create images based on temperature differences. This technology is commonly used in various fields, including surveillance, building inspections, and medical diagnostics. Infrared cameras can reveal details that standard cameras cannot, such as identifying heat leaks in buildings or detecting fever in individuals. They are equipped with specialized sensors that convert infrared radiation into visible images, making them valuable tools for both professionals and hobbyists interested in thermal imaging.
