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 technology behind thermal imaging relies on sensors that capture temperature differences. Warmer objects appear brighter in the images, while cooler areas are darker. This capability makes thermal cameras useful for identifying heat loss in buildings, locating people in low visibility situations, and diagnosing medical conditions related to temperature changes.
