The infrared camera is based on the same principles as the infrared thermometer. However, the camera makes a scan of a specific image area, using a cooled semiconductor detector. The individual measurement pixels are electronically converted into a picture. The infrared shows things that are otherwise not visible to the naked eye. Infrared cameras produce images of the invisible infrared or heat radiation and make precise non-contact temperature measurement possible.

Thermography uses a camera to visualize the thermal energy radiated from an object. .

Temperature can be displayed in different shades of gray or different colors. The infrared camera gives an overview of all parts of the building and, e.g. thermal bridges can easily be recognized.
