The curved connecting piece between the wall mount and the camera mount screw is made of flexible plastic that acts like a spring. The camera will bounce back and forth every time the wall or anything else the mount is attached to vibrates, e.g. B. when closing a door. Also, unless the camera is parallel (or almost parallel) to the wall, the distance between the wall and the camera must be close enough to allow you to see the camera screen to check settings or correct alignment. Again completely useless.
