PTZ Controls
If the video encoder has been appropriately configured, the Live View page displays the controls available for the installed Pan
Tilt Zoom (PTZ) device. The administrator can enable/disable the controls for specified users under System Options > Security
> Users > User List.
The controls shown depends on the PTZ device. The most common controls are:
• the Pan bar – moves the camera to the right and left
• the Tilt bar – tips the camera up and down
• the Zoom bar – zooms the view in and out. Note that this is only available if the camera is fitted with a
zoom lens
• the Iris bar – adjusts the brightness of the image
Clicking on the bars themselves or on the arrows at the end of the bars moves the camera to a new position. The type of
movement and the location of this new position depends on the type of PTZ driver.
When controlling the camera using a relative PTZ driver the new position
is relative (see right) to the previous position, for example, left of, below, or
above. Clicking the bar further from the center results in a larger
movement.
In contrast, when using an absolute driver, each position on the bar (see the bars in the illustration above) represents a
defined position in the device's range of movement, with the center of the bar representing the point midway between the
two extremes of movement.
Clicking a position directly on the bar moves the camera directly to the new position in one smooth movement. Clicking on
the arrows at the ends of a bar causes an incremental change.
