Starts a continuous move
Declaration
function ONVIFPTZStartMove (PTZType: string; OppositeDirection: Boolean; SpeedRatio: Double; DurationMs: LongInt): Boolean;
BOOL _ONVIFPTZStartMove (void *TVGObject, const wchar_t * *PTZType, BOOL OppositeDirection, double SpeedRatio, int DurationMs);
Description
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.
