Table 4-6 Auto Exposure Settings
Description
Electronic shutter control. Select ELC when using a manual iris lens.
Adjust the ELC level to the appropriate value so that the image is well
exposed (neither too bright nor too dark).
Select ALC when using a DC (auto iris) lens. Adjust the ALC level to
the appropriate value so that the image is well exposed (neither too
bright nor too dark).
Adjust the maximum value of AGC gain. AGC can be Off, or set to
20 dB, 30 dB, or 40 dB.
Note As AGC levels are reduced, the threshold ranges for
DayToNight and NightToDay are decreased.
Improves picture performance in low light by reducing video noise.
DNR will remove video noise, but will also soften the image.
Off - DNR is turned off.
Auto - DNR is automatically controlled by the firmware according to
changes in the lighting condition.
Fixed - DNR is manually set to the highest value regardless of
changes in the lighting condition. You will get the least video noise
(dots), but the softest image.
DNR is deactivated if AGC is turned Off.
Eliminates the "flicker" that can appear in an image under certain
lighting conditions (for example, fluorescent lighting). This setting is
not available if you have selected ELC.
Automatically provides a clear image under low-light conditions. DSS
improves the picture quality (brightness) in low-light scenes. DSS
might introduce motion blur; the higher the setting, the more likely
motion blur will occur.
Controls Day/Night (SDN) operation.
Sets the color mode as B/W (monochrome) or Color in Night Mode.
Day/Night must be set to Night.
