Infrared cameras?

[Shmoov69]

Hey guys, anyone of you know much about infrared cameras and such? I know nothing about them other than there are a lot of choices and price ranges. I would be interested in buying one for my work, but don't want something overpriced, over optioned for no more than I would use it. I am a commercial roofer (flat roofing) and want to use it for moisture scans and building heat loss etc..

Thanks in advance!

Fluke makes a hand held one that's very similar to their IR temp guns. I want to say it was like this http://www.bing.com/shopping/visual-ir-thermometer/p/35DAED887D32254B5020?q=fluke+ir+camera&lpq=fluke%20ir%20camera&FORM=HURE

It was used by my professor and his understudy to conduct energy audits on the buildings around campus. Pretty neat tool.
