IMAGE ENHANCEMENT
(Applies only to 35X models.)
The image enhancement feature improves the definition of objects, lines, or text in high contrast areas, making them appear sharper.
There are two image enhancement settings:
DEFAULT: Image enhancement is not activated.
ENHANCED: Image enhancement is activated.
LOW LUX NOISE REDUCTION
(Applies only to 27X and 35X models.)
Low lux noise reduction helps to reduce video noise in low light scenes. When enabled, low lux noise reduction is directly affected by the AGC
settings for the dome system.
The following are the low lux noise reduction settings:
ON (default): Low lux noise reduction is enabled. As the scene darkens and AGC increases, the noise reduction effect automatically increases.
As noise reduction increases, you may also notice some afterimaging and a slight reduction in color saturation.
OFF: Low lux noise reduction is disabled.
WIDE DYNAMIC RANGE
(Applies only to 27X and 35X models.)
Wide dynamic range (WDR) balances the brightest and darkest sections of a scene to produce a picture that is better balanced in lighting and
provides more detail.
Available settings are OFF and ON; the default setting is OFF. When wide dynamic range is set to ON the frame rate is reduced from the standard
30 to 15 frames per second (fps). Also, when this setting is ON the iris will not close completely, even in manual mode.
Note: Wide dynamic range is disabled when electronic image stabilization is set to 5 Hz or 10 Hz.

Warning: When using this feature be aware that picture noise, although unnoticeable to the eye, will increase and may cause
compression rate changes in DVRs, NVRs, and network devices.
