Infrared cameras are special devices that can see heat instead of visible light. They detect infrared radiation, which is emitted by all objects based on their temperature. This allows them to create images that show temperature differences, making them useful for various applications like building inspections, wildlife monitoring, and even medical diagnostics. These cameras are often used by professionals such as firefighters to locate hotspots in a fire or by electricians to find overheating wires. They can also help in energy audits to identify areas where heat is escaping from buildings, leading to more efficient energy use.
