Rear view camera - changed angle

[ChrisMiller]

After a recent 'wash and brush up' (using a local 'hand wash' operation), I notice that the scene shown in my rear view camera has changed. It's now pointing lower down, so when I back up to my garage it only shows the bottom half of the door and a small part of the car bodywork is visible. I'm not complaining, it may be a slightly better view for my purposes, but I wonder how it was possibly done. Can you take off the protective cover and adjust the camera angle - has anyone tried this? There's nothing visibly changed externally that I can see.

My camera is actually moving if I push it hard enough, you can adjust it with a finger.
