the general brightness of the video as a whole. The video color may become too strong if the value is
too high. For the gray part of the video, distortion may occur if the white balance is not accurate.
Also, video quality may be degraded if the value is too low. The recommended value ranges from 40
to 60.
Gain. Move the slider to set the gain value. Generally speaking, the smaller the value, the lower the
noise—although the contrast may be too low in dark environments. A higher setting can enhance the
video brightness, though this may increase video noise.
Color Mode. Move the slider to set several modes such as standard, color, bright and gentle. Then
when you select a color mode, the sharpness, brightness and contrast automatically switch to the
corresponding setups.
Digital Cameras
The following are settings for digital cameras:
Channel. Select a channel from the dropdown list.
Auto Iris. Enables or disables the auto iris feature, which automatically adjusts the iris opening to
respond to changes in light levels.
Mirror. This feature switches the video up and bottom limit. This is disabled by default.
Saturation. Move the slider to adjust the monitor window saturation. The value ranges from 0 to
100. The default value is 50. The larger the number, the strong the color. This value has no effect on
the general brightness of the video as a whole. The video color may become too strong if the value is
too high. For the gray part of the video, distortion may occur if the white balance is not accurate.
Also, video quality may be degraded if the value is too low. The recommended value ranges from 40
to 60.
