Constraints on pan influence camera selection through <a>fitness distance</a> toward cameras with the ability to pan. To exert this influence without overwriting the current pan setting, pan may be constrained to true. Conversely, constraining it to false disfavors cameras with the ability to pan.

<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.
