Exactly!
I have such a camera for some years, it became my most efficient troubleshooting tool as soon as my nose rings the bell... and even beyond that.
Recently I was checking an HP function generator that blew the fuse.
Fuse replaced, cautious ramp-up on the variac with the IR-cam in the other hand, one of the rectifiers quickly made its "streetlamp"...
