The more I use my infrared camera, the more problems I find and the bigger the benefit for everyone concerned. I have discovered it is not a perfect tool, but it is a great aid in detecting some problems. I currently use it mainly for moisture intrusion problems. Typically any home I suspect has a water problem, I will take my camera out of the car and use it. Between my infrared camera, moisture meter, and experience of inspecting thousands of homes, I get a little more comfortable with it and so should the buyers.
The digital picture on the left (top) looks normal as you view underneath the window banks. The infrared picture on the right (bottom) shows dark stains inside the wall as a result of moisture getting into the wall cavity and rearranging the insulation. Since the insulation has been moved, it created a difference in temperature, which is what we actually see.
