My house was broken into a couple years ago. Windows smashed and the place vandalized. I felt violated for months. I had no security footage then and the police said it was a waste of time to dust for fingerprints. I wish I had Ring then - I do now. I am happy now that thieves know when they approach my house now they are being filmed and shared with police.
I know the Hacker News crowd is very against this - in a very out of touch way - but I am extremely pro being able to share footage from my private residence with law enforcement and am happy local law enforcement may finally have some tools to solve repeat burglaries.
If that's indeed what they do I really don't see any issues, on the contrary that sounds like the way forward.
Currently police has to go door to door to ask neighbours if they have any CCTV and then get the SD cards or what not in order to recover footage.
Given Ring is a doorbell, the chance that it's going to help cops stop murders or serious crime seems a bit of a far-fetched marketing statement, and it's more likely to catch petty theft and porch pirates.
