Description
Electronic shutter control. Adjust the level until the image is neither too
bright nor too dark.
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
is deactivated if AGC is turned Off.
Eliminates the "flicker" that can appear in an image under certain
lighting conditions (for example, fluorescent lighting).
Automatically provides a clear image under low-light conditions
(increasing magnification may cause noise/distortion).
Set the moving mechanical IR filter within the camera to ensure true
24-hour surveillance.
Sets the color mode as B/W (monochrome) or Color in Night Mode.
Day/Night must be set to Night.
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.
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.
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.
