We purchased the Ring Peephole as privacy shrubs in our driveway would hinder view of a normal Ring Doorbell.
**My suggestion is to add a small screw in the back to prevent the back from being able to turn (perhaps at the bottom of where the battery goes).
I’ve tried tightening it as much as possible, but I don’t want to risk breaking our new device. However after tightening it is still very easy to turn from the back, even with the adapter in place. The front of the camera doesn’t have this issue.
