8. Function Switches – This compartment houses
switches for camera operation. A switch is in the ON
position if it is positioned toward the front of the
camera. If the position is set toward the back of the
camera, the switch is OFF. The switches include:
•
AGC Switch – The auto gain control switch
allows the video signals to maintain a constant
level. This switch is useful when using the
camera at low-light levels and when lighting
levels change over time.
•
GAM Switch – The gamma correction switch
allows .45 correction for non-linearity gain
response in the monitor when set to ON. When
set to OFF, there is no gamma correction.
•
A/I Switch – The auto iris switch allows the user
to select the supplied auto-iris control signal for
the lens. Position the switch toward the front of
the camera to choose DC when the auto-iris
control lens requires dc control signal. Position
the switch toward the back of the camera to
choose Video when the auto-iris control lens
requires video signal.

Phase – Phase adjustment is used in multicamera systems when power is supplied from
different sources, thus causing the camera to be
out of phase. This in turn affects auto-switching
by causing rolling of the video during the switch
interval. The vertical phase adjustment allows
the camera’s line lock sync to be adjusted from 0
to 360 degrees with zero line crossing of the ac
power source. To effectively use the phase
adjustment, ensure that all cameras are
powered from the same electrical source and
are wired in a similar fashion. Then, adjust the
phase control on the top of the camera until
there is no rolling video on the monitor when
using the auto-switcher.
Iris – This control adjusts the level of the auto
iris when the A/I lens selection switch is set to
the dc position and a dc lens is mounted on the
camera. The switch should be in the VIDEO
position when an auto-iris video lens is used. If a
video auto-iris lens is used, this adjustment has
no function.

Apply power to the camera.
6.
Adjust the focus ring on the lens for an optimum
picture. If the picture is not visible, set the lens for
proper exposure by adjusting the ALC (automatic
level control) and Level on the lens. The ALC setting
can range between AVG (average) or PK (peak). An
AVG setting is appropriate for most applications.
For ALC adjustments:
AVG
To slow the reaction of the lens to
changing light, set the range on the AVG
setting to average the video level from the
camera. Use this when there are bright
spots in the picture, such as lights or glare
from the sun.
PK
To increase the speed of the lens reaction
to the changing light, set the lens
adjustment to PK so the lens will adjust to
the brightest or peak object in the video.
Use this setting if you want to see the
brightest object and not the background
objects.
For Level adjustments:
Adjust the Level control for the best picture during
the day. A night adjustment may not provide the
proper setting for controlling the light during the day.
