Either carry it with them or enter a passphrase (for use with a key derivation function; I guess/hope that Ring requires some passphrase to view video via their website anyway). That's a rather common problem. As for "AI", depending on what you mean by that, it can be implemented in the device itself (unless it's something particularly fancy, requiring more resources than viable to dedicate there). It's indeed easier and slightly more convenient to not care about security, but that's also a general/common case.
