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).
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 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 True Day/Night (TDN) operation. When Auto is selected, the
IR-cut filter will be removed automatically in low-light scenes. When Day
is selected, the IR-cut filter is on at all times. When Night is selected, the
IR-cut filter is off (removed) at all times.
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 or a normal light
condition, respectively.
Day/Night must be set to Auto.
Wide dynamic range provides clear, balanced images in high-contrast
lighting conditions. Set the WDR to Off, Low, Medium, or High.
When On, LDC reduces picture distortion. The performance of Frame
Rate mode might be impacted by LDC.
