Calling a Camera to View on a Monitor
After a monitor has been called to the control of the AD2079 (see page 3-1), a camera can be
called to view on the monitor. Each system camera has a unique identification number
documented by the system administrator.
To call a camera:
1. Enter the camera identification number on the numeric keypad (the number appears in the
ENTER display).
2. Press the CAMERA key (the number clears from the ENTER display, and appears in the
CAMERA display).
The selected video input now appears on the monitor screen. After calling a camera to the
selected monitor, any other camera can be called to the monitor by repeating the two step
procedure described above.
Controlling a Camera's Pan and Tilt
Once an appropriately equipped camera has been called to view on a monitor, the operator can
manually control the camera's movement. Pan is the side-to-side movement of the camera. Tilt is
the up and down movement of the camera.
The AD2079 joystick controls the panning and tilting of cameras connected to the switching
system. As the joystick is moved to the left or right, and is moved towards or away from the
operator, the camera will pan and/or tilt accordingly.
For cameras with variable speed pan/tilt capability, camera movement speed is proportional to
the positioning of the joystick. The further from the stationary center position the joystick travels,
the faster the camera will move. There are eight independent speed levels for the up, down, left,
and right directions.
Center the joystick when the camera has been positioned appropriately.
Locking and Unlocking a Camera
After calling a pan/tilt camera to view and control on a system monitor, an operator can prevent
other operators from controlling the movements of the called camera by pressing the LOCK key.
To unlock the camera press the LOCK key again.
Controlling Camera Zoom
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. Zoom
functions can also be controlled by twisting the control knob of the three-vector joystick. Twisting
to the right enables the camera to zoom in. Twisting to the left enables the camera to zoom out.
Controlling Camera Focus
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. To return to auto focus/auto iris capability when using the AD168 system equipped
with a Control Code Module, press the OPEN and CLOSE keys simultaneously. See Appendix E
for commands used with SpeedDome series domes used with the AD2083-02A code translator.
Controlling the Camera Iris
Normally, the brightness of a picture is controlled by the camera's auto gain and the auto/manual
iris functions. However, there may be times when you would like the picture on the monitor to
