Software installation
At the end of the hardware installation, users can use Installation Wizard program
included in the product CDROM to find the location of the Video Server. There may be
many Video Servers in the local network. Users can differentiate the Video Servers with
the serial number. The serial number is printed on the labels on the carton and the back
of the Video Server body. Please refer to the user’s manual of Installation Wizard for
detail.
Once installation is complete, the Administrator should proceed to the next
section "Initial access to the Video Server" for necessary checks and
configurations.
- 12 -
www.vivotek.com
Initial Access to the Video Server
Check Network Settings
The Video Server can be connected either before or immediately after software
installation onto the Local Area Network. The Administrator should complete the
network settings on the configuration page, including the correct subnet mask and IP
address of gateway and DNS. Ask your network administrator or Internet service
provider for the detail information. By default the Video Server requires the
Administrator to run installation every time it reboots. If the network settings are to
remain unchanged, disable the Install option. Refer to “Network settings” on the
System Configuration page for details. If any setting is entered incorrectly and cannot
proceed to setting up the Video Server, restore the factory settings following the steps
in the “Troubleshooting” chapter of the Appendix.
Add Password to prevent Unauthorized Access
The default Administrator’s password is blank and the Video Server initially will not ask
for any password. The Administrator should immediately implement a new password
as a matter of prudent security practice. Once the Administrator’s password is saved,
the Video Server will ask for the user’s name and password before each access. The
Administrator can set up a maximum of twenty (20) user accounts. Each user can
access the Video Server except to perform system configuration. Some critical
functions are exclusive for the Administrator, such as system configuration, user
administration, and software upgrades. The user name for the Administrator is
permanently assigned as “root”. Once the password is changed, the browser will
display an authentication window to ask for the new password. Once the password
is set, there is no provision to recover the Administrator’s password. The
only option is to restore to the original factory default settings.

How to Use
Authentication
After opening the Web browser and typing in the URL of the Video Server, a dialogue
window pops up to request a username and password. Upon successful authentication,
the following figure is displayed.
The foreground is the login window and the background shows the message if
authentication fails. The user may check the option box to save the password for future
convenience. This option is not available to the Administrator for obvious reason.

Installing plug-in
For the initial access to the Video Server in Windows, the web browser may prompt for
permission to install a new plug-in for the Video Server. Permission request depends on
the Internet security settings of the user’s PC or notebook. If the highest security level
is set, the computer may prohibit any installation and execution attempt. This plug-in
has been registered for certificate and is used to display the video in the browser. Users
may click on
to proceed. If the web browser does not allow the user to
continue to install, check the Internet security option and lower the security levels or
contact your IT or networking supervisor for help.

Client settings
At the initial access to the “Connection type” page in Windows, the web browser will ask
for a new plug-in installation, the plug-in being the Video Server. This plug-in has been
registered for certification and can be used to change the parameters at the client’s site.
The user may click on
to install the plug-in. If the web browser does not allow
the user to complete the installation, check the Internet security to lower the security
level or contact your IT or networking supervisor.
There are two settings for the client side. One is “Media Option” for users to
determine if audio should be muted. The other is “Protocol Option” which allows
choices on connection protocol between client and server. There are three protocols
choices to optimize your usage - UDP, TCP and HTTP.
The UDP protocol allows for more real-time audio and video streams. However, some
packets may be lost due to network burst traffic and images may be obscured.
The TCP protocol allows for less packet loss and produces a more accurate video
display. The downside with this protocol is that the real-time effect is worse than that
with the UDP protocol.
- 18 -
www.vivotek.com
The HTTP protocol must be selected if the network is protected by a firewall and it only
allows HTTP Port (80) to be opened. In this mode, audio will not be sent and only video
is operational. If no special need is required, UDP protocol is recommended. Generally
speaking, the client’s choice will be in the order of UDP → TCP → HTTP. After the
Video Server is connected successfully, “Protocol Option” will indicate the selected
protocol. The selected protocol will be recorded in the user's PC and will be used for the
next connection. If the network environment is changed, or the user wants to let the
web browser to detect again, manually select the UDP protocol, save, and return HOME
to re-connect.

Administrator’s capability
Fine-tuning for Best Performance
Best performance generally equates to the fastest image refresh rate with the best
video quality, and at the lowest network bandwidth as possible. The three factors,
“Maximum frame rate”, “Fix bit rate”, and “Fix quality” on the Video Configuration page,
are correlative to allow for achieving the best performance possible.
For Best Real-time Video Images
To achieve good real-time visual effect, the network bandwidth should be large enough
to allow a transmission rate of greater than 20 image frames per second. If the
broadband network is over 1 Mbps, set the “Fix bit rate” to 1000Kbps or 1200Kbps, and
set “Fix quality” at the highest quality. The maximum frame rate is 25 in PAL system
and 30 in NTSC system. If your network bandwidth is more than 384Kbps, you can fix
- 20 -
www.vivotek.com
the bit rate according to your bandwidth and set the maximum frame rate to 25 fps or
30 fps. If the images vary dramatically in your environment, you may want to slow the
maximum frame rate down to 20 fps in order to lower the rate of data transmission.
This allows for better video quality and the human eyes cannot readily detect the
differences between those of 20, 25, or 30 frames per second. If your network
bandwidth is below 384 Kbps, set the “Fix bit rate” according to your bandwidth and try
to get the best performance by fine-tuning with the “Maximum frame rate”. In a slow
network, greater frame rate results in blur images. Another work-around is to choose
“Half” in the “Size” option for better images, or “Halfx2” for a larger image view. Video
quality performance will vary somewhat due to the number of users viewing on the
network; even when the parameters have initially been finely tuned. Performance will
also suffer due to poor connectivity because of the network’s burst constraint.
Only Quality Images Will Do
To have the best video quality, you should set “Fix quality” at “Detailed” or “Excellent”
and adjust the “Maximum frame rate” to match your network’s bandwidth. If your
network is slow and you receive “broken” pictures, go to the TCP protocol in
“Connection type” and choose a more appropriate mode of transmission. The images
may suffer a time delay due to a slower connection. The delay will also increase with
added number of users.
Somewhere Between Real-time and Clear Images
If you have a broadband network, set “Fix quality” at ”Normal” or better, rather than
setting “Fix bit rate”. You can also fix the bandwidth according to your actual network
speed and adjust the frame rate. Start from 30 fps down for best results but not below
15 fps. If the image qualities are not improved, select a lower bandwidth setting.

Opening accounts for new users
Protect Video Server by passwords
The Video Server is shipped without any password by default. That means everyone
can access the Video Server including the configuration as long as the IP address is
known. It is necessary to assign a password if the Video Server is intended to be
accessed by others. Type a new word twice in ○

to enable protection. This password is
used to identify the administrator. Then add an account with user name and password
for your friends in ○
2
. Video Server can provide twenty accounts for your valuable
customers or friends. Each account identifies the access right rather than the real
visitor. That allows multiple visitors share the same account of different level. An
option to access DI/DO is provided for each account. Some users may need to prohibit
from controlling your attached devices. You may delete some users from ○
