Sending footage to the cops because you saw a crime is just being a snitch, at worse. And being a snitch shouldn't be a bad thing when we are talking about property or violent crime happening in a neighborhood. No where related to being a vigilante. A vigilante would "fix the problem" then let someone else call the cops about the noise. Maybe also get it wrong and end up in jail.
Cops automatically pulling footage could be a concern. How the footage is used could also be a concern. Giving evidence to the cops about break-ins or package thief isn't.
