Table 4-5 Auto Exposure Settings
Setting Options Description
ELC (Electronic Light
Compensation) Level: 1-25 Electronic shutter control. Adjust the level until the image is neither too
bright nor too dark.
ALC (Automatic Light
Compensation) DC Iris Level: 1–25 For an automatic iris lens. Adjust the DC Iris Level until the image is
neither too bright nor too dark.
AGC (Automatic Gain
Control) Off, 10 dB–40 dB 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.
DNR (Digital Noise
Reduction) Off, On Improves picture performance in low light by reducing video noise. DNR
is deactivated if AGC is turned
Off .
Flickerless Off, On Eliminates the “flicker” that can appear in an image under certain
lighting conditions (for example, fluorescent lighting).
Digital Slow Shutter
(DSS) Off, Low, High Automatically provides a clear image under low-light conditions
(increasing magnification may cause noise/distortion).

DayToNight 1–7 Determines the low light detection level ( 1 – 7 ) when the camera
switches to Night mode. The lower the value, the darker the lighting
conditions must be before the camera switches.
Day/Night must be set to
Auto .
Note The DayToNight threshold level must be set at least 2 less than
the NightToDay threshold setting.
Note The DayToNight threshold range is decreased if the AGC level is
reduced.
NightToDay 3–9 Determines the low light detection level ( 3 – 9 ) when the camera
switches to Day mode. The higher the value, the brighter the lighting
conditions must be before the camera switches.
Day/Night must be set to
Auto .
Note The NightToDay threshold range is decreased if the AGC level is
reduced.
