Right. These devices are not used just to look for hot spots, but for cool spots too. So if you live in the Arizona sun, the whole wall may light up on the display, but then the circuit box be a darker cool spot in the middle, with a slightly warmer (and suspicious) spot in the middle of the circuit box.
I guess this depends on the imager's capabilities
Yeah, the better models need a difference of just 2 or 3 degrees to "show" it on the display. And just 1.4F if you want to spend $2500 or more.
