thermal cameras are cheap relative to what they used to cost 15 or 20 years ago.

Does anyone have a recommendation for a thermal camera for non-commercial use? I’d like to use a thermal camera to diagnose my thermal envelope of my house and to see what progress I make with incremental improvements.

I’m a little opposed to getting one that would plug into a phone since I worry the app or phone connection will be obsolete/unsupported within the next 7-10 years or so. 

I know I can rent one or check one out of my local library, but that’s less attractive since I ‘d have to do more planning.

Any recommendations are appreciated.
