Can thermal imaging night vision really penetrate walls?

Nowadays, thermal imaging night vision has been used more and more widely these years, but in fact, many people don’t know much about thermal imaging technology. Today, I will give you a little science about infrared thermal imaging ~

Can thermal imaging night vision penetrate walls? Generally speaking from the current technology, thermal imaging cannot penetrate the wall. In life, if the wall is thick enough, its insulation is sufficient to block the infrared radiation on the other side. If you point an infrared camera at a wall, it will detect the heat of the wall, and the heat behind it cannot be detected completely. But if something inside the wall can cause enough temperature difference, the camera can also sense it on the surface of the wall.

For example, some building maintenance professionals often use thermal imaging night vision to detect problems such as water leakage or insulation loss. These tests do not require dismantling the wall to evaluate the problem.
