Wedge mount upside down

The heighth location of my doorbell is kind of low and doesn't get the upper part of the person. Would be useless if I can't see the head of the person. The wedge kit typically is used when it's on a higher location pointing downward. Can it be the mount be installed on the wall upside down so it angles the camera at an upward angle so I can capture the upper part better? Will the camera be mounted upside down if I do this and cause other issues? Or can the mount be install on the wall upside down and have the ring attached right side up?
