Thermal imaging is a technology that detects infrared radiation (heat) emitted by objects and converts it into an image. This allows you to see temperature differences and visualize heat patterns. It's widely used in various fields, including:

1. Surveillance and Security: Detects people or animals in low-light conditions or through obstacles like smoke or fog.
2. Building Inspections: Identifies heat loss, electrical issues, or moisture problems in buildings.
3. Medical Imaging: Assists in diagnosing conditions by detecting abnormal heat patterns in the body.
4. Firefighting: Helps firefighters see through smoke and locate hotspots.
5. Military and Law Enforcement: Used for navigation, targeting, and surveillance.
