In the real world of a building inspection we look for things such as hidden moisture. As the moisture spreads out and evaporates after several days, it gets harder and hard to pick up those sub-surface temperatures on the surface materials. Moisture areas can be conducive to mold, decay and wood destroying insects. Many times the hidden moisture temperature is very close to the dry area and not much energy reaches the surface for your camera to see. This is when a good quality IR camera is needed.
The worst IR camera on the market can take a photo a hot heater or guitar. It is the hard to find issues that we are worried about, not the obvious. Hype does nothing to change the facts that even FLIR will not endorse these cell phone IR cameras as tool of measurement or should be used by professional building inspectors. I have two written statements from FLIR regional sales rep who have stated that these low resolution cameras are not to be used for professional use.
Just the facts please.
