Workstation monitors display the video from the cameras and
domes. Each monitor has an identification number assigned by the
system administrator.
To select a monitor,

2. Press the MON key. The monitor number will appear in the
MONITOR display window. This monitor has now been called to
the keyboard. Camera video can now be viewed on the called
monitor (To allow selecting monitor via keyboard, please
configure the 8-position DIP switch on the bottom of the
keyboard). Or set the proper combination of the DIP switch
according to Table 2-1, the monitor ID selected will be displayed
on the monitor LED display automatically.
3.2 Video Switch
A camera can be called to view on a selected monitor. Each system

display).
The selected video input now appears on the monitor screen. Any
other camera can also be called to the monitor by repeating the

3.3 Camera Control
3.3.1 Pan/Tilt Control
Pan refers to the horizontal movements of the cameras, while tilt
refers to the vertical movements of the cameras. Once an
appropriately equipped camera has been called to view on a monitor,
operators can manually control P/T by using V2110 joystick. After
the camera has been positioned appropriately, release the joystick.
3.3.2 Lens Control
Camera zoom control
Zoom refers to the apparent action of moving closer to or farther
away from an object, as seen through the camera lens.
By pressing the TELE key, the camera appears to move closer to the
object.
By pressing the WIDE key, the camera appears to move away from
the object.
Camera Focus Control
Focus refers to the action of adjusting the clarity of the camera
image displayed on the monitor.
To focus the camera on a distant object, press the FAR key.
To focus on a closer object, press the NEAR key.
Camera Iris Control
Sometimes, it may be necessary to manually control the brightness
of a picture, which is normally controlled by the camera's auto gain
and the auto/manual iris functions.
To brighten the picture, press the iris OPEN key.
To darken the picture, press the iris CLOSE key.
3.4 Calling Presets
A preset, also referred to as shots, is a memorized location or scene
that a pan/tilt camera can display on operator demand. Depending
on the matrix switching system used, the operator will have the
option of calling a certain number of presets, each with its own
unique identification number.
To call a preset,
1. After calling a pan/tilt camera to view, enter the preset
identification number on the numeric keypad.
2. Press the SHOT key to call the preset of the camera under control.
The selected video now appears on the monitor screen with
appropriate pan, tilt, zoom, and focus adjustments.
3.5 Running System Tours
A tour is a dynamic sequence of camera views, each of which has a
specified dwell time, pre-programmed preset status, auxiliary status,
and connect next designation. System tours, also referred to as
universal tours, are characterized by the particular switching system
they are designed for. System tours are programmed in the Menu
mode. In addition, there are monitor tours, which are temporary
tours programmed for the operator's currently selected monitor.
Monitor tours are set up in the Program mode.

pan/tilt/lens adjustment, and auxiliary on/off control, can be
performed on the held camera.
