VB.NET

Public Function ONVIFPTZStartMove(PTZType As String, OppositeDirection As Boolean, SpeedRatio As Double, DurationMs As Integer) As Boolean

C++/Qt

BOOL ONVIFPTZStartMove (wchar_t *PTZType, BOOL OppositeDirection, double SpeedRatio, int DurationMs);

Starts a continuous move of the specified PTZ.

PTZType can be "Pan", "Tilt" or "Zoom"

SpeedRatio is usually in the 0 .. 1.0 range

• if the camera supports a limited move duration and a DurationMs value > 0, the camera will automatically stop the move when this duration is elapsed.

• if the camera does not support a limited move duration, the camera moves until ONVIFPTZStopMove is invoked.
