     <li><dfn>Tilt</dfn> is a numeric camera setting that controls the tilt of the camera. The setting represents tilt in arc seconds, which are 1/3600th of a degree. Values are in the range from -180\*3600 arc seconds to +180\*3600 arc seconds. Positive values tilt the camera upward when viewed from the front, and negative values tilt the camera downward as viewed from the front.
