Good design but using an inductive sensor as a home switch is a bad idea. Too expensive and low precision. A simple IR LED with a photoresistor or a hall effect sensor with a magnet would be better and cheapper.
Also, consider using a planetary gearbox instead the giant gear. If your camera pointing up and you remove the power of the motor the camera will fall. Too risky. A planetary gearbox will lock the output gear and the motor doesn't need to stay powered, saving energy and preventing driver and motor overheat.
