Setting Options Description
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).
Day/Night Auto, Day, Night Set the moving mechanical IR filter within the camera to ensure true
24-hour surveillance.
Night Mode B/W or Color Sets the color mode as B/W (monochrome) or Color in Night Mode.
Day/Night must be set to Night.
Detect Time 5–60 seconds Sets the time (5–60 seconds) before the camera switches to Day or
Night mode after detecting a low-light condition.
Day/Night must be set to Auto.
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 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 before the camera switches.
Day/Night must be set to Auto.
Note The NightToDay threshold range is decreased if the AGC level is
reduced.
