In simple terms, IR is the energy emitted by objects based on their temperature. The higher the temperature, the more energy emitted. Everything in the world emits this energy; however some things emit better than others. To make it more complex, there are also objects in the world that act as reflectors. This is where the limitations of the camera can come into play. First, the cameras are not able to “see through” objects but rather the detect surface temperature of objects. A good example is wall framing members that can be seen with the camera because they heat up or cool down differently than the insulation.
