The default is AUTO.
Use a short center press to save the video standard. The display blinks and the cursor exits to the menu.
Automatic (AGC)
When configuring a DC-drive auto iris lens or when focusing the camera, you may have to temporarily enable or disable automatic gain control
(AGC). The AGC feature automatically adjusts the image when the light level changes. AGC will be disabled for some procedures since it can
affect camera configuration (refer to Lens Setup and Focus Procedures).
To simplify camera setup, the Automatic (AGC) option appears in two menus: LENS/VIDEO SIGNAL and GAIN CONTROL. Changing the AGC
setting on one menu also changes the AGC setting on the other menu. (Refer to Gain Control for information on using AGC for camera operation.)
Select ON to enable AGC.
Select OFF to disable AGC.
The default is ON.
Lens Type
Select DC to use a DC-drive auto iris lens.
Select MANUAL to use a manual iris lens.
The default is DC.
LINE SYNCHRONIZATION
Use line synchronization to eliminate the vertical roll that occurs when multiple cameras are connected to
the same switching device. Line synchronization locks each camera to the same frame rate.
Line Sync
Select INTERNAL for installations with DC power or noisy AC power, or if you are using Pelco V-Sync.
Select LINE LOCK to manually set the vertical phase for this camera. You will also change the V-PHASE
ADJ setting. (Refer to Camera Synchronization for more information.)
The default is INTERNAL.
V-Phase Adj
To adjust the vertical phase line synchronization, move the V-PHASE ADJ slider from 0 to 624. The default is 519.
VIDEO LEVEL
Use this menu to adjust the video signal output level.
Video Level
Use this slider to set the video output voltage from 1.0 Vp-p to 1.2 Vp-p in increments of 0.02 Vp-p. Use it
to compensate for signal loss due to long cable runs. You can also use it to boost the video output.
The default is 1.0 Vp-p.
IRE Setup
Use IRE SETUP to set the minimum black level for this camera. Use this setting to either increase or
decrease the amount of contrast in an image. This feature is enabled with NTSC only.
Select 0.0 to lower the minimum black level for use with unevenly lit scenes. It produces greater contrast in the darker portions of an image.
Select 7.5 to raise the minimum black level for use with evenly lit scenes. It produces greater contrast in the evenly lit portions of the image.
The default depends on the selected profile (refer to Table K).
NOTE: The CCC5100H Series camera does not support video-drive auto iris lenses.
