First access to Video Server
When connecting to Video Server for the first time, administrators should check security and
network settings on the configuration page. For complete protection from illegal usage, Video
Server provides two privileges and always needs user name and password before access. The
standard level is the USER mode that consists of twenty user profiles. Each user is able to access
Video Server except for system configuration. The twenty user profiles are also maintained by
the administrator. The highest level is ROOT mode that only opens to administrators for initial
setup, system configuration, user administration and software upgrade. The user name of the
administrator is internally assigned to “root”.

memorized since there is no way to retrieve or recover it. After changing the password, the browser will
display an authentication window again to ask for the new password.
The other important part is network settings. The software configuration above makes Video
Server easily accessed through local networks. However administrators should review the
network settings on the configuration page according to the existing service. The safe and easy
way is to compare the network settings with another PC or workstation in the same network.

mask as 255.255.255.0. Administrators should change the subnet mask if it differs from the one
provided by server. Administrators should also fill in the default gateway, primary and secondary
domain name servers if necessary.
By default Video Server will need administrator's installation every time it reboots. If the
