Great example +1; however in this example cops assumed Mr. Vargas to commit crime and hence setup cam to watch aka surveillance his property 24/7. Very difference from situation where average citizens records their front yard 24/7 not expecting or assuming a crime will occur, and then having that video being obtained when the crime happens.

In other words, this case is about active surveillance, versus Ring cams are more passive (record everything all the time for no specific reason)

Ring is marketed as a security camera, and one of it's primary use cases is providing video recording in the event of a crime.

Exactly! Not marketed as a tool to surveillance your neighbor 24/7.
