Tracking Feature with Logitech Quickcam Sphere/Orbit

Motion supports controlling the pan and tilt feature of a Logitech Quickcam Sphere/Orbit.

Motion can move the camera to a fixed position given in degrees pan (left-right) and tilt (down-up). Movement can be set with absolute coordinates or relative to current position. There is also an auto tracking feature for the Logitech Quickcam Sphere/Orbit but it is not very mature. It is fun to play with but not very useful yet. See this topic of how KennethLavrsen controls his Sphere: LogitechSphereControl.

For a detailed description of http remote control see the section Remote Control with http.

• Value 4 is the generic track type. Currently it has no other function than enabling some of the internal Motion features related to tracking. Eventually more functionality will be implemented for this type.
