To use this widget, drag it directly from the videoDriver palette onto a Px page, then drag the widget boundaries to adjust the layout size and position the widget to fit directly over the video display.
After binding the widget to a camera component, you have a transparent control overlay with which to pan, tilt, and zoom the camera at three speeds: Slow(>), Medium (>>), and Fast (>>>) by dragging the mouse across the display.
NOTE: Camera controls do not operate unless they are
Enabled. Each of these controls must be enabled by selecting the option box for each control under the PTZ Support property on the
camera Property Sheet. The default setting for these controls is Disabled (or, not selected).
