Thermal imaging cameras are devices that detect infrared radiation, which is emitted by all objects based on their temperature. These cameras convert the infrared signals into visible images, allowing users to see heat patterns. They are commonly used in various fields, including building inspections, firefighting, and medical diagnostics. The images produced by thermal cameras, known as thermograms, display different temperatures in various colors. Warmer areas appear brighter or in warmer colors, while cooler areas are shown in darker or cooler colors. This technology helps identify issues like heat loss in buildings or locating hotspots in electrical systems.
