Ring does not have a local stream
Ring cameras do not speak to the LAN. Every local port is closed. Video goes to Amazon and comes back if the account — and every hub in the location — is happy. One lighting bridge knocked offline by a Powerwall install hung the whole Ring house. The MQTT bridge sat waiting for hubs. That is the product.
Decision: Reolink where the stream lives on the wire. Frigate as the NVR — person, car, recordings, into HA without Amazon. A delivery is a person at the driveway and the front door, not a cloud clip. If a stream wedges, the Reolink path still notifies. Remaining Ring stays in the Ring app until that box is a Reolink. Do not hang a cloud bridge off a local NVR.
What it bought: the cameras still work when Amazon, or one dead hub, does not.
