What does a thermal infrared camera detect?

  1. The presence of moisture

  2. The presence of mold

  3. The presence of UV

  4. Temperature differentials

The correct answer is: Temperature differentials

A thermal infrared camera is designed to detect temperature differentials by capturing infrared radiation emitted from surfaces. This capability allows it to visualize variations in temperature across a given area, which can be indicative of various conditions such as heat loss, insulation issues, or air leaks. When surfaces are at different temperatures, the camera can produce images that highlight these differences, offering valuable insights for diagnosing problems in buildings, energy efficiency assessments, and identifying hidden moisture or electrical issues. In contrast, the other options do not fall within the primary function of a thermal infrared camera. While moisture and mold might affect temperature readings indirectly, the camera does not specifically detect these substances or UV radiation, as its focus is purely on heat emission.
