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 25 and Auto IR Level section on page 24.
VIDEO LEVEL
Set the video output to one of the following options:
NORMAL: 1.0 Vp-p.
HIGH (default setting): 1.2 Vp-p. to compensate for losses in video cable.
