Hi na8.
It might be worth it to contact the West Seattle Tool Library:
http://wstoollibrary.org/
In entering “camera” on their website, they have an “inspection camera” available, which is apparently one of those cameras for looking into tight, hidden spaces. In glancing at the manufacturer’s site for the specific item, I didn’t see where it had any thermal capabilities.
BUT, WSTL may have some ideas, or connections to a thermal cam.
Good Luck!
Mike
