Controlling Camera Movement
General
Camera positioning is controlled via an eight-way
joystick (four buttons on TC8551A and TC8554 type
keyboards) on the right hand side of the keyboard.
This joystick moves the camera pan/tilt, if equipped,
up, down, left, right or diagonally. To operate the
pan/tilt, use the following procedure:
1. Move it left to pan the camera left.
2. Move it right to pan the camera right.
3. Move it up to tilt the camera up.
4. Move it down to tilt the camera down.
EXAMPLE: Pressing up and right simultaneously
will move the camera diagonally up and to the
right.
Lens Control
On the left side of the keyboard are the lens control
rocker switches. The camera's zoom lens, if
equipped, can be controlled to zoom in or out, focus
near or far, and open or close the iris (if the lens has
manual iris override capability). Lens control is
carried out by pressing the lens rocker switches in
one of two possible directions as follows:
1. Press ZOOM to zoom in or out (rotate the
joystick knob on TC8553 and TC8555 type
keyboards).
2. Press FOCUS to focus far or near.
3. Press IRIS to open or close the iris.
EXAMPLE: Pressing ZOOM will cause the lens
to either zoom in or out. The direction is a
function of the lens type and wiring, but direction
can be reversed through a DIP switch change in
the receiver/driver if desired.
Recording Camera Pre-Position
A user can record and store a camera position for
later push-button recall. Please note that although
the capability exists in the receiver/drivers, the
pan/tilt and zoom lens must have the necessary
options for pre-position operation. If the
AutoDome
™
series of dome cameras is being used,
certain preposition commands are also used to
activate operational features and functions. A
summary list of the various AutoDome commands is
included in the Appendix section of this manual for
your reference. Refer to the AutoDome user manual
for complete information. To record a camera
position, use the following steps:
1. Move the appropriate camera to the desired
position.
2. Press the SET key and verify that the SET
indicator lights.
3. Press the desired position number using the
numeric keypad.
4. Press ENTER.
EXAMPLE: SET 2 ENTER
The above example will store the position of the
pan/tilt and zoom settings into memory for later
recall.
Recalling the Pre-Position
A prerecorded camera position can be recalled using
the following steps:
1. Press the SHOT key and verify the SHOT
indicator lights.
2. Key in the number of the scene to be recalled
using the numeric keypad.
3. Press ENTER.
EXAMPLE: SHOT 2 ENTER
The above example will recall the position stored in
location 2 and automatically move the pan/tilt/zoom
to return to the prerecorded scene. Note that if a
second pre-position is called prior to the completion
of the first, the camera will move directly to the
second shot. If the AutoDome
™
series of dome
cameras is being used, certain preposition
commands are also used to activate operational
features and functions. A summary list of the various
AutoDome commands is included in the Appendix
section of this manual for your reference. Refer to
the AutoDome user manual for complete information.
Clearing a Pre-Position
A stored pre-position may be cleared using the
following steps:

2. Press 9 followed by the pre-position number.
3. Press ENTER.

being viewed. Note that this capability can only be
used with newer TC8561A Series receiver/drivers
that are compatible with this feature. If the
AutoDome
™
series of dome cameras is being used,
certain preposition commands are also used to
activate operational features and functions. A
