No luck restarting it. Maybe it will fix itself again.
Hopefully just overheated.
Main Cam started working again.
It really shouldn't overheat in these conditions. It's a security camera that's meant to work adjacent to asphalt parking lots in places like Texas and Arizona.
But it has always been a bit finicky, so maybe it did overheat.
Who knows. Maybe it was the control computer overheating. We had that happen once upon a time. Just glad it's back!
