Unifi protect setup for a neighborhood gate

The gate in our neighborhood needs new cameras and I was looking at using unifi protect since I have it at home and it works fantastic. The thing is, there is no buildings or air conditioned areas to put a cloud key in at. The cloud key would have to be mounted in a weather proof outdoor enclosure.

I’m worried about the cloudkey overheating since I know they do run pretty warm in AC already. Would it be possible to mount it in such an enclosure? Would just 120mm intake and exhaust fans be enough year round? Maybe a peltier cooler cooler (not sure how many watts of cooling)?
