It’s going to crash. Lived in similar conditions (desert), and no iPad or iPhone can handle streaming in ambient temps of 110+ F.

You will need to cool the device down, there’s no way to avoid that. Either put it inside a cool environment or attach a massive heat sink/cooler to it.

Insulation wouldn’t help since the iPad generates heat. Unless you mean something else by “insulation” than what I am thinking.

Active cooling would be the way to go, but beware of the noise fans will create in the mic.
