My customers are concerned about privacy. If they’re worried someone can use thermography cameras like the FLIR ONE to spy inside someone’s home or underneath their clothes, what can I tell them?

Thermography cameras don’t provide x-ray vision, they allows you to visualize and measure the surface temperature of most objects. In many cases, the surface temperature of an object can be affected by things behind or under the surface. For example, under certain conditions the surface temperature of awall can be subtly affected by the wooden studs behind the wall. This characteristic can allow you to easily see the location of the studs behind the wall, without actually looking through the wall. It may be helpful to have them watch the “Introduction to Thermal Imaging” video available at
