Street mailbox camera tied to doorbell

The Ring doorbell videos rarely capture license plates of package thief cars that stop.

For those homes with mailboxes in the parkway, consider a camera mounted on the mailbox post or tree to capture license plate info. This would also capture drive by mailbox theft. If too far from base station, have it communicate via Ring doorbell to base station. This would provide valuable information to the police. A speed sensor could help as well to help report cars speeding through neighborhoods.

How would one prevent someone from tampering with a mailbox camera? Seems pretty easy for someone to take it or just use spray paint to block it.
A speed sensor, though useful for information, would never stand up in court or be accurate enough for a speeding ticket. It could be useful to get you local government to provide speed bumps (or other methods) for chronic speeding locations.
