Auto Iris Peak
Increasing the peak value will cause the auto iris circuit to react more to highlights or “peaks” in the picture. Decreasing this value will cause it
to use the average video level to adjust the iris.
AUTO SHARPNESS
Auto sharpness enhances picture detail by increasing the aperture gain of the camera and sharpening the edges in the picture.
There are two settings:
ON (default): The camera automatically maintains a normal sharpness mode.
OFF: The sharpness of the picture is set manually by configuring the sharpness level. Sharpness level settings range from 0 to 63.
AUTO WHITE BALANCE
This feature automatically processes the viewed image to retain color balance over a color temperature range. The default setting for auto white
balance is ON.
R GAIN: Adjusts the picture output in the red range. As you change the value, you will see the color change on your monitor.
B GAIN: Adjusts the picture output in the blue range. As you change the value, you will see the color change on your monitor.
BACKLIGHT COMPENSATION
If a bright backlight is present, the subjects in the picture may appear dark or as a silhouette. Backlight compensation (BLC) enhances objects in
the center of the picture. The dome uses the center of the picture to adjust the iris. If there is a bright light source outside of this area, it will
wash out to white. The camera will adjust the iris so that the object in the sensitive area is properly exposed.
There are two backlight compensation settings:
OFF (default): Backlight compensation is not activated.
ON: Backlight compensation is activated.
If backlight compensation is ON, decrease the auto iris level setting and adjust the auto IR level to a darker setting. Refer to Auto Iris Level on
page 26 and Auto IR Level section on page 25.
ELECTRONIC IMAGE STABILIZATION
(Applies to 35X models only.)
Electronic image stabilization is a feature of the camera that can compensate for some forms of external influences. In all cases, care should be
taken to make sure that any dome system is mounted to a rigid location.
In the event that vibration is introduced to the dome system, a user can select one of the electronic image stabilization settings in the menu. The
available settings are OFF, 5 Hz, and 10 Hz. Users should apply each of the settings to the camera to see which one best addresses the vibration
that is affecting the video quality.
Electronic image stabilization will not correct for all ranges of vibration. If either of the settings fails to eliminate the vibration seen in the video,
other measures should be taken to isolate the vibration or to seek a more rigid mounting location.
NOTES:
• When electronic image stabilization is applied, digital slow shutter and wide dynamic range are disabled. Zoom, image resolution, and
viewing angle are also limited when this feature is activated.
• Electronic image stabilization cannot be used while in a preset that has motion detection activated.
WIDE DYNAMIC RANGE
(Applies to 27X and 35X models only.)
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.
