An infrared thermal imaging camera shows temperature differences, commonly referred to as an "anomaly", on the surface. These differences are revealed in different colors (red for warmer areas and blue for cooler surfaces with various shades in-between).

• Infrared thermal imaging is not x-ray vision. It will not reveal what is going on beneath the surface
  
  
• Infrared thermal imaging does not tell you if the temperature difference is from cold/warm air infiltration, moisture that is not visible to the naked eye, or a result of the flow of conditioned air in a room
  
  
• You cannot look at a thermal image and determine of mold is growing inside a wall
  
  
• Infrared thermal imaging will not tell you if a mechanical component with a warmer or cooler temperature is normal or a defect
