3.3.2 Video
Use the
Video
menu to set all the video parameters for the cameras con-
nected to the
VP-580. There is one video screen for each camera with
the following parameters:
• Standard
– sets the video signal format. Choose NTSC in the
US, or PAL in Europe and most Asian countries. If you are not
sure about this option, select Auto.
VP-580 will detect the video
standard automatically.
• Brightness
– adjusts the amount of light or brightness for the
selected camera according to your preference.
• Contrast
– adjusts the difference between light and dark areas or
contrast for the selected camera according to your preference.
• Saturation
– adjusts the amount of color for the selected camera.
• Hue
– adjusts the dominant color for the selected camera.
• Quality (All)
– adjusts the video quality for all cameras. The
default setting is 80. We recommend that you do not set this to
100 to avoid a slower rate of video transmission and using up a
significant amount of hard disk space.
• Compression
Boost
– enables you to compress the video signal
to save disk space and thus extend recording time. It is recom-
mended to keep this setting to None. The higher the compression
boost, the lower the video data rate.For a significantly lower data
rate, we recommend you use the H.263 algorithm (see
Algorithm
on page 35).
• Auto Gain Control
– enables automatic gain control to adjust
the video signal strength.
• Mirror Horizontal
– flips the video signal from the selected
camera along the horizontal axis.
• Mirror Vertical
– flips the video signal from the selected camera
along the vertical axis.(Live video only)
• Max Connection
– limits the maximum number of connections
allowed to access the VP- 580 over the Internet. Set to zero to
allow the maximum number of connections.
• Max Bandwidth
– sets the maximum bandwidth in bytes/second
that can be used by users connecting to the
VP-580 over the
internet.
