Did he work for flir??!!I had a lend of of a thermal imaging camera from college a few years back. We were trying to use it to see where heat was escaping from an old badly insulated building (a former coat factory converted into a community centre) , so we could make recommendations to what part of the building needed work the quickest.
The camera cost something in the region of €7,000 and was pretty useless, the lecturer reckoned if you weren't spending 40k on a flir you were wasting your time.
We were taught how to use it as part of a maintenance engineering degree to see and monitor things like hot bearings, hot spots in gearboxes, and bad connections in industrial fuseboxes.

The decent ones I've used are not cheap(fluke and flir), but certainly not 40k worth. IIRC 3-4 k would get you a pretty handy one able to take Ir and camera pics for surveys.
They worked fine for what we used them for, (checking hotspots on thermal oxidisers and dryers, checking elec panels, bearings etc) and I was able to find out I had better insulation (or a colder house!) than my neighbours.
No he didn't work for flir, but the one we had was pretty hopeless and that cost over 5k. We did see flir cameras that had come from flir, when they were looking to sell the college one, they were streets ahead , no comparison.
