"Subnet Mask", "Default Router", "Primary DNS" and "Secondary DNS". After changing
network settings, be sure to leave "Reset network at next boot" blank to skip installation when
the system restarts. Otherwise the settings will be erased.
Video Server not only plays the role of server, it will also actively connect to servers outside to
send out messages or snapshots. When Video Server starts, it will send out a system log to
notify administrators. Even in modem application, Video Server will send out a connection log
whenever it dials out to an ISP or dialup server outside. If the administrator has setup some
applications in either event mode or sequential mode, Video Server will send out snapshots
once conditions are met. There are two methods to send files, including e-mail and FTP. To
ensure Video Server sends out files correctly, administrators should set valid "SMTP (mail)
server" and "Recipient email address" as well as "Primary FTP Server", "Primary FTP user
name" and "Primary FTP password". “Return email address” is whom the mail will return
when the SMTP server rejects upon any failure. Some ISP may reject the mail if the address is
invalid. "Primary FTP remote folder" is the relative sub-folder in the remote FTP server.
In both methods, a "Secondary" server can be provided for backup connection. However the
primary server information should be entered first. If the primary server is not set, the related
FTP or email will be deactivated. Note that it may take time to connect to the secondary server
after the first one fails and it may affect some applications when conditions happen too often.
For security or network integration, administrators also can hide the server from the general
HTTP port by changing "HTTP port" to other than default 80. “Local FTP server port” can also
be changed to other than default 21. These ports of “Control Channel Port”, “Audio Channel
Port” and “Video Channel Port” which are used in media transmission can also be changed.
Administrators should have enough acknowledge before changing the default port.
If the Video Server works in variation or low bandwidth (comparing with video bandwidth)
environment, the client side will receive the poor quality of media. For improving this situation,
you can check the “
Improve audio quality in low bandwidth environment” item. It can make the
audio quality better, but the media delay is longer and real-time issue is bad. If the network performance
is worst, please select the ”UDP protocol“ as the communication protocol in “client setting”
After everything is set, click on
. A warning message will pop up. Click on to confirm.
Video Server will automatically restart. If "Reset network at next boot" is kept checked, run the
installer procedure again. Otherwise Video Server will restart automatically.
