Adjusting The Camera AGC
The unit has a versatile camera-by-camera AGC Range adjustment. This allows you
to set the unit up via simple menus to compensate for camera inputs that have
excessive video levels outside of the normal AGC range. This is a set up function
which would normally be used by the installer.
Example
Cameras with auto-iris lenses can be adjusted during installation so that the video is
consistently at a much higher level (brighter) than the standard video signals. This is
often done to compensate for cable losses, or simply to improve the general video
appearance. This may take the video levels beyond the range of the unit’s AGC.
The multiplexer allows you to easily adjust the input AGC separately for each camera
from the front panel controls.
To adjust the input AGC for any camera, select the Camera AGC sub-menu from the
main menu.
The default AGC range setting is 5 for all inputs.
Adjusting The VCR Brightness And Contrast
The multiplexer provides a simple front panel adjustment to digitally adjust the
contrast and brightness of the playback signal from the VCR. This can also be used
to compensate for some VCRs which output a higher or lower video signal level than
the standard.
To adjust the VCR signal contrast and brightness, select PLAY mode
and then
select the playback camera image to be enhanced full-screen on Monitor-A. Use the
arrow keys
to adjust the signal.
VCR Playback Brightness
Use the up/down arrow keys
to adjust the brightness.
VCR Playback Contrast
Use the left/right arrow keys
to adjust the contrast.
Macro Functions
Macro Functions allow you to pre-program frequently-used key sequences, and
frequently-used menu setups. These can be quickly executed as a two-keystroke
function.
