A thermal camera is a device that detects infrared radiation, which is emitted by all objects based on their temperature. It converts this radiation into a visible image, allowing users to see heat patterns. This technology is commonly used in various fields, including building inspections, firefighting, and medical diagnostics. Thermal cameras can identify heat leaks in buildings, locate hotspots in electrical systems, and even assist in diagnosing medical conditions by visualizing blood flow. They are valuable tools for enhancing safety and efficiency in many applications, making them essential in both professional and industrial settings.
