John,
I just received my BCAM 4:30 p.m. yesterday! Totally unbelievable!
The weather was cool here last night and I had no temperature difference in my house to speak of and I found all kinds of stuff!
I saw a great big square above my attic storage door, went inside and found a piece of missing insulation.
I can now quickly and accurately test if the electric hot water heater is functioning with both elements properly.
I can even find my dog sleeping in the bushes in the dark! 
I did find two false anomalies right off the bat!
A metal threshold on the door into my attic space reflected my body heat making it look like hot air infiltration, but there was no hot air in the attic at the time.
I found a cool spot on an exterior wall after sundown which turned out to be radiational cooling from an adjacent window that was slightly open at the top.
This is an unbelievable tool, but you have to know what you’re looking at! My extensive background in thermodynamics is a great asset in visualizing what the camera is looking at. It’s also extremely important to understand what you should expect to see inside a finished wall or ceiling. Under the right conditions I could see the entire framing system of my cathedral ceiling as if the sheet rock and roof had been removed! I built this house so I know what’s in there.
As many have said, training is essential. Also many have said that this tool can be a liability, which is true. However, it is written all over the operation/training manual that you must not rely on one source of testing. This is crucial to know what is the difference between air infiltration, lack of insulation and water intrusion!
There is actually very little input on this site about thermography. I have gotten a few e-mails on people researching the subject. I think we could use a separate section on this subject where we can all share our investigative experiences and photographic results. Nick might even be able to get somebody from FLIR or other vendor to hang out there!
Would like to see what Will Decker has compiled. He seems to be the IR guru around here? 
Let’s get that building science course information posted here.
There you are Will, You slipped in there wile I was typing! Is this really free? I think $1 is a bit much seeing as I can by disks for less! :-0 LOL
Can’t seem to “help out” anyone these days without a disclaimer can you!?!
