Infrared Thermal Imaging Inspection cameras see temperature changes and differences in real time that are invisible to the naked eye. Thermal cameras cannot see inside walls or ceilings. This allows testing without requiring destruction or contact. Thermal cameras are used for mold inspections as no exterior or interior finishes need to be taken down, and large areas can be inspected in a short time. Thermal imaging cameras have become a common inspection tool.
A thermal imaging camera detects small temperature differences and displays a picture of these differences so that we can see them. They work indoors and outdoors, and on wood, concrete, drywall, electrical wiring etc.
