FAQ about Thermal Cameras (2024)

Thermal imaging ot thermographies works on capturing infrared light emitted from objects, they are unaffected by the visible light. So, yes you can use the thermal imaging camera in daylight.

No, Thermal imaging cameras do not see through surface but detect surface temperatures. If a wall is thick enough to trap the heat on one side without leaking it into the other side then thermal imaging will not detect it. However, if the condition results in a change in the surface temperature of the wall it will be picked up by the thermal imager.

No, the thermal imaging camera can only pick up the surface temperature of the object. If any object on the other side of the metal heats it up so that the surface temperature changes, the camera will be able to pick up the temperature variation, but will not provide a see-through experience.

Thermal imagers cannot pick up visible light. Therefore, Glass is not seen as transparent when viewed through a thermal imaging camera.

No, thermal imaging cameras can detect the temperature of the cloth but will not see through it. However, if a person is carrying something that is heating or cooling the cloth that covers it, the thermal camera will show the heat signature on the cloth.

No, the thermal imager does not emit any form of radiation. It’s a sensor which converts records infrared radiation and processes it for human use.

Thermal imagers can detect through a light amount of fog, rain, dust, smoke, and snow. However, as these conditions worsen, it lowers the visibility of the thermal camera.

The thermal imager cannot see through a significant depth of water. But an object that has a variance in temperature compared to the surrounding water can be picked up with relative ease, the water is shallow enough.

Cooled thermal cameras come with a cryocooler that lowers the detector temperature to cryogenic temperatures. They offer better image quality than uncooled thermal cameras but come at additional cost.

Yes, thermal imaging can produce pictures even if there is no presence of visible light. Night vision cameras work by boosting the ambient light. So if there is no ambient light, then night vision cameras will fail to register a usable image. Learn more about how a thermal camera works here.
