Won't be home for a while, so I can't take a picture for you, Bill.
The doorbell is about 2" wide. It fit pretty flush on the frame and is well mounted. You could break it off with a crowbar if you wanted, but it would be recording you the whole time.
As it records, the video is being uploaded to the cloud. I pay something like $100/year for Ring to store the video, every video, that it takes, so even if it were destroyed, the video would be available.
Further, if it's stolen, Ring will replace it.
The security of the device is a minor concern for me, not a big one.
I like the unit a lot, even bought the Ring floodlight/camera for the backyard.
They're both a hair too sensitive, for example, a squirrel on my deck will trip the lights and video in the back yard. But in playing with the settings, I would rather not have any missed video, so, I've left them on the sensitive side.
