Thermal Technology

Essess uses thermal camera technology to see if and where your home is losing energy. These cameras capture thermal energy to show where a home’s hot and cold spots are.

Thermal cameras work differently from regular cameras. They work best at night because solar radiation causes interference. And they work best in winter because the quality and accuracy of thermal images depends on the contrast between the outside temperature and a home’s interior temperature.

Our cameras are mounted on the roofs of cars that travel on public roadways, except when an organization (such as a university) asks us to participate in an energy efficiency study of its buildings.
