I think it’s important to understand that if the whole Internet just shut off in an instant, life as we know it would cease to exist. I’m not talking about a cultural change. I mean millions of people starving and freezing to death because literally everything you take for granted today is ordered, scheduled, and delivered using the Internet. That means no food deliveries, no fuel deliveries, no imports or exports, no trains, trucks, or planes moving, no payments or money transfers. Nothing. Oh, and all the emergency services that you’re going to need will be unable to respond because no phones and no communication from dispatch centers. We don’t know how to do business without the Internet anymore, so if it goes away, there goes your way of life. Building that back to the “old way” will take way longer than you or your neighbors are likely survive competing for essentially nonexistent resources.

But for those who manage to survive, I would say party like it’s 1899!

Oof! Guess I should have looked at that.

Not sure if this meets your needs but you might check out DoorBird. They claim to work with several NAS solutions and have an API, as well as the usual phone- and tablet-notification and communication through their own service.

You are indeed, but it points to a fallacy in the original question. It’s not universal basic income if it is stipulated that you have to do something to receive it.
