Cloud access is typically if you’re managing equipment at multiple sites. For me everything is accessed and managed locally and the recordings are saved to a local HDD and not uploaded to the cloud.

I’ve got a Ubiquiti setup with cameras and a doorbell. It isn’t cheap but it’s local and I highly recommend them if you have the budget.

Seems like a perfect candidate. Astronauts are intelligent, determined, hard working and don’t freak out in pressure situations.
