Remarks

The Value member of the KSPROPERTY_CAMERACONTROL_NODE_S structure specifies the relative tilt.

Note that a particular device might support only a certain speed range. To determine the range of speeds supported by the device, an application can issue a KSPROPERTY_TYPE_BASICSUPPORT request. You can specify KSPROPERTY_TYPE_BASICSUPPORT in the Flags member of the KSPROPERTY_ITEM structure.

Some devices support only a single tilt speed. In this case, the sign of the Value member indicates which direction to tilt.

When making a set request, the client should supply one of the values in the preceding table in the Value member of the KSPROPERTY_CAMERACONTROL_NODE_S structure.

When making a get request, the client receives one of the values in the preceding table in the Value member of the KSPROPERTY_CAMERACONTROL_NODE_S structure. The value indicates the current tilt status of the camera.
