Infrared (thermal imaging) is an advanced, non-invasive technology that allows the inspector to show homeowners temperature variations within their homes that can’t be revealed using conventional inspection methods. 

 Thermal cameras make pictures from heat, not visible light. Heat (also called infrared, or thermal, energy) and light are both parts of the electromagnetic spectrum. Still, cameras that can detect visible light won’t see thermal energy and vice versa.

Thermal cameras detect more than just heat; they detect tiny differences in temperatures – as small as 0.01°C – and display them in different shades.
