The Camera Mount attaches to the Watch Box and holds your iPhone in place. IMPORTANT: the Camera Mount should not be attached to the center of your Watch Box bracket. Remember, the lens on an iPhone isn’t in the center of the iPhone, it’s at the top corner of the iPhone. So just put the iPhone lens at the center of your Watch Box setup. The Camera Mount will be mounted off-center by a couple inches, and the iPhone body might look off-center, but your camera lens itself should be perfectly centered.
