Thermography makes pictures from heat, humidity, moisture, and water not visible light.  Thermal cameras detect anomalies in the building envelope and building components. This is a completely different technology that produces a scientific perspective that is not seen by the human eye. 

Thermal imaging works by detecting subtle, or vast changes in temperature caused by the presence of moisture, water, humidity, or heat. A thermal imaging camera can help you trace the water back to its origin. It gives Thermal readings that portray definitive signs of changes due to a building component being impacted.

In this Thermographic image to the right you can clearly see the water and moisture in the wall. The darker area in the far right window portrays an area that is saturated with water. Further to the left you see shades of water and moisture present.
