Thermal cameras detect temperature by recognizing and capturing different levels of infrared light. This light is invisible to the naked eye, but can be felt as heat if the intensity is high enough. All objects emit some kind of infrared radiation, and it’s one of the ways that heat is transferred. The hotter an object is, the more infrared radiation it produces. Thermal cameras can see this radiation and convert it to an image that we can then see with our eyes, much like how a night vision camera can capture invisible infrared light and convert it to an image that our eyes can see.

Can thermal imaging see through clothing?

Not really. Although, if, for example, a suspect had an unnatural foreign object under their shirt, its exterior area would appear “cooler” to the camera and indicate to management that someone may be carrying something concealed.

Can thermal cameras be used to detect a virus or an infection?

The quick answer to this question is no, but thermal imaging cameras can be used to detect elevated skin temperature.

How far can the camera detect?

Measurement distance: 0.8m-2.5m or 2m-7m depending on the option chosen.

How accurate is the temp detection?

Measurement accuracy ±0.5 °C or ±0.3 °C depending on the option chosen.
