1: Can thermal imaging see through walls?
No, thermal cameras cannot see through walls, at least not like in the movies. Walls are generally thick enough—and insulated enough—to block any infrared radiation from the other side. If you point a thermal camera at a wall, it will detect heat from the wall , not what’s behind it. However, if something inside the wall causes enough of a temperature difference, a thermal imager will be able to sense it on the surface of the wall. Building maintenance professionals often use thermal imagers to detect issues like water leaks or missing insulation without needing to tear down walls to assess the problem.
2: Can thermal imaging see through smoke?
Yes, thermal cameras can detect heat through smoke, and are widely used by firefighters for this purpose. Soot particles in smoke effectively block visible light, but allow infrared radiation to pass through, letting firefighters or other first responders navigate through smoke-filled environments.
3: Can thermal imaging see through fog?
Fog and rain have the potential to severely limit the range of a thermal camera due to the scattering of radiation off water droplets. However, in many circumstances, thermal cameras can penetrate fog much more successfully than visible light cameras or the human eye. This is one reason why car manufacturers are incorporating thermal imagers into the sensor suites of autonomous vehicles.
3: Can thermal imaging see through glass?
Fun fact: glass acts like a mirror for infrared radiation. If you point a thermal imager at a window, you won’t see anything on the other side of the glass, but you will get a nice reflection of yourself in thermal. This is because glass is a highly reflective material, meaning it shows the reflected temperatures of objects rather than letting infrared radiation be transmitted through. The same principle applies to other reflective materials, like polished metal.
Our factory have varies types of thermal imaging camera, for vehicle, for long range observation,for rifle and so on. Warmest welcome to contact me
