Axis Communications 2401 - Manual (Page 30)

Using the Video Server AXIS 2400/2401 Admin Manual 30
Positional Control of the Video Sources
Video cameras supporting Pan Tilt and Zoom (PTZ) are connected and controlled directly
from the unit’s serial ports. Depending on the type of PTZ device used, the AXIS
2400/2401 can control up to four external (stand-alone) PTZ devices for positioning
cameras on your system.
Clicking a specific Video button other than Video All, automatically displays
pan-tilt-configured video sources in a single-image format that features Pan, Tilt and
Zoom bars, as shown in the illustration below:
Notes: •Clicking anywhere on the toolbar’s gradient allows for a “smooth” PTZ adjustment; whereas
clicking on the left or right arrows causes a stepped incremental change.
•The AXIS 2400/2401 can control a range of relative and absolute PTZ devices via the Web inter-
face, or third-party TCP application. The positioning tools available from the main page depend
on the PTZ device chosen by the Administrator.
•Pan Tilt control can be disabled by the Administrator and may be unavailable in the user inter-
face.

zontal panning of the camera.

Select Preset Position
To enable quick and accu-
rate camera positioning,
the Administrator can
define within server mem-
ory, up to 20 preset camera
positions. Preset positions
are created and saved as
named entities by your
Administrator and can be
selected at any time from
the drop-down dialog.
Choosing a preset position
from the drop-down dialog
immediately causes the
selected camera to assume
the predefined orientation.
Focus
Allows smooth or stepped
camera focus between near
and far focus.
