I wouldn't be surprised if Ring overstated their impact.
That being said systems like Ring are pretty amazing. I can log on and people around the neighborhood (big city) are posting videos/images of people who broke into their house or were acting suspiciously late at night. I imagine even if just a slice of these lead to arrests in the short term it could lead to a very good impact in the future (both because the people who were stealing would have likely repeated if they weren't caught + if it becomes perceived as harder to rob a house less people will attempt it).
