Image Settings

Click on this button to pop up another window to tune “Brightness”,

“Contrast”, “Hue” and “Saturation” for video compensation. Each field has eleven

(11) levels ranging from -5 to +5. In the “Brightness” and “Contrast” fields the value

“0” indicates auto-tuning. The user may press

to fine tune the image. When

the image is O.K., press to set the image settings. Click on to recall the

original settings without incorporating the changes.

Optimizing Image Quality

Best performance generally equates to the fastest image refresh rate with the best

video quality, at the lowest network bandwidth as possible. There are three factors for

the MPEG-4 mode (“Maximum frame rate”, “Constant bit rate”, and “Fix quality”) and

the “Maximum frame rate” and “Fix quality” for the JPEG mode. These setting may be

adjusted to provide the best image quality and/or frame rate for the specific network

environment.
