BNC video inputs “IN” & outputs “OUT”
Video Server allows up to four cameras attached at the same time. To ensure video
modulation type being detected correctly , cameras should be attached sequentially from
“VIDEO1” to “VIDEO4” and powered on before Video Server is powered on. There are
also four loop-through connectors of video outputs for conjunction with other capturing
devices like time-lapsed VCR. In such case, read the next paragraph for correct settings.
DIP switches “1” to “4”
There are four DIP switches numbered from “1” to “4” in the front panel regarding of
each video input. They are used to enable the 75-ohm resistan ce of video impedance.
They should be kept ON if there is only one camera connected to each video input. If
users want to connect another device such as VCR or multiplexer to the video output, the
switch should be turned up to disable the impedance.
Auxiliary buttons “CLEAR” & “RESET”
There are two buttons located at the center of the front panel, one is labeled “CLEAR”
and the other is labeled “RESET” . Refer to the Appendix Troubleshooting
for the detailed
usage of system recovery.

Rear Panel
Ethernet 10/100 socket
Connect to an Ethernet network with a UTP category 5 cable of length shorter than 100
meters according to the standard. Once the Ethernet cable is connected without error,
Video Server will utilize the Ethernet interface prior to the modem attached to COM2.
COM1 port
This RS232 serial port is dedicated to controlling the PTZ cameras attached to COM1
unless the administrator pre-configures COM1 as an RS485 interface that is accessed
through two pins in the general I/O terminal block.
COM2 port
This RS232 serial port can connect with a modem or the included null modem cable to
utilize dial-up network when Ethernet is not available. If Video Server operates with an
Ethernet interface, the administrator may use this port to control another PTZ cameras
attached to this serial port.
General I/O terminal block
Video Server provides a very flexible general I/O interface to combine with the use r’s
security devices such as sensors, alarms, lighting or door locks. Two green connectors
are included in the package to connect the external devices. The general I/O terminal
block has twenty pins for device control. These pins can be divided into three categories
based on their functions, including power source, RS485 and digital inputs and outputs.

Power source
Pair of pin 11, 12 of AC or DC input is a replacement with the power adapter in case the
range cannot meet the requirement. The voltage of the power source can be AC or DC
and should fall in the range between 12V and 15V. Polarity does not matter. The DC
output through Pin 1, 2 is fed from power adapter of Video Server or pin 11 and pin 12
if an external power source is attached. The current of external devices is limited to less
than 500mA.
The power adapter of Video Server and the external power supply are prohibited to
exist together. Only one source can feed power to Video Server. Improper usage will
result in serious damage.
RS485 interface
If the device connected to COM1 has an RS485 interface, wire two control lines to pin 9
and pin 10. After switching to RS485 on the configuration page, the PTZ control
commands will be directed through pin 9 and pin 10. If the distance from the controlled
- 10 -
device is too far to allow accurate function, an external power source may be used to
amplify the RS485 signal.
Digital I/O control
Video Server provides four pairs of digital inputs and two sets of relay switches. Pin 13 to
pin 20 can be connected to external sensors and the state o f voltage will b e mon itore d
according to the programmed conditions on the configuration page or the external script
file. Both relay switches can be used to tu rn on or off external devi ces. When the system
starts up, COMMON of both relay switches will be short with NC. A simple diagram of
example is shown below.
Power adapter
Plug the power jack of the included power adapter to Video Server . Connecting the power
adapter should be the last operation while physically installing Video Server.
Administrators may feed an external power source through pin 11 and pin 12 of the
general I/O terminal block to replace the power adapter.
The power adapter of Video Server and the external power supply are prohibited to
exist together. Only one source can feed power to Video Server. Improper usage will
result in serious damage.
If DI1 in configuration is set as rising to
drive DO1 to high that denotes COMMON o
f
DO1 short with NO, then the bulb will light
when DI1 signal changes from 0V to 12V.

Installation
To easily fit into various environments, the Video Server automatically detects the
attached interfaces and configures itself to the best condition. Therefore users need not
care whether the connected cameras are either NTSC or PAL, how to select the network
between Ethernet and modem, and whether the Ethernet speed is 10Mbps or 100 Mbps.
If the connected motorized camera is on the support list, users only ne ed to plug and
play without complicated configurations.
The Video Server supports Ethernet and modem interfaces according to the user's
existing network. Ethernet can provide higher bandwidth to achieve the best
performance while dial-up network with modem is more co mmon in current Internet
applications. Refer to the related installation section for your network environment. If
both interfaces are available, Ethernet is recommended and will be chosen as the first
priority if Ethernet cable and modem are concurrently attached. Managing to install in
the other interface will automatically clear the previous network setting s to start new
installation.
In the following content, "user" refers to those who can access the Video Server and
"Administrator" refers to the supervisor who has the root password to configure th e
Video Server in addition to general access. Administrator should carefully read this
manual, especially during installation.
- 12 -
Ethernet Environment
Hardware installation
Before installing multiple Video Server’s at the well-chosen locations, the administrator
should memorize the serial numbers on the packages respectively for future use.
Cable connection
Shut down all the peripheral devices prior to connection. The video BNC, Ethernet cable
and power adapter are essential for basic viewing function. If the attached cameras
belong to the same motorized model, they can be concatenated to single COM port and
will be differed by camera ID set on the cameras. Refer to the related configuration
section for detailed description.
Power on
Make sure all cables are correctly and firmly connected. Before turning on Video Server,
remember to run Installer program on PC or notebook in the same network first. As long
as the “Reset network at next boot” option in network Web page is enabled, the
Installer program is needed to install Video Server. Turn on cameras, sensors, alarm
devices, and then attach power adaptor of Video Server to the electric power socket.
After the POST (power-on self test) is complete and the result is successful, Video Server
is ready for software configuration as described in this manual. At this stage, network
speed and video modulation type are automatically detected.
- 13 -
Initial Access to the Video Server
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. For complete protection from illegal usage, the 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 the Video Server except for system configuration. Twenty users’ profiles
are also maintained by the administrator. The highest level is ROOT mode that only
opens to Administrator for initial setup, system configuration, user administration and
software upgrade. The user name of the Administrator is internally assigned to “root”.
When connecting to the Video Server, users will be requested for user name and
password by an authentication message window. A root password, identical to the Video
Server's serial number, is needed for the initial access to a newly installed Video Server .
The administrator must change the root password immediately after the initial
installation to ensure security. The new root password should be well 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
the Video Server easily accessed through local networks. However Administrator 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.
By default the Video Server will acquiring IP address automatically every time it reboots.
If the network settings are sure to work all the time, disable the “Reset network at
next boot” option if this IP address is already reserved for this the Video Server.
Clearing this option will fix IP address of the video server every time it boot s up. If the
option stays checked, the Video Server will pick up any available IP address
automatically every time the system boots up.
- 14 -
Modem Environment
Hardware installation
Though Video Server is designed to serve real-time images in Ethernet, it also supports
the dial-up network. To use a dial-up network, the Ethernet socket should be left
disconnected since Ethernet is the first priority among available interfaces. After
powering up, Video Server will detect if any external modem is connected to COM2. As
soon as a modem is detected, the heartbeat LED will flash periodically. If no modem
responds, Video Server will assume the included null modem cable is connected to
perform system configuration. Then both LED’s under the power LED will turn on until
the dial-up connection over null modem is established.
Installations of both null modem and modem are introduced as follows. The null modem
mode can be used for point-to-point connection in local environment; the modem mode
also applies to TA in ISDN network. Though the baud rate can be setup to 115200 bit per
second, the actual data rate depends on the network connection.
In the following content, dial-in connection denotes a passive Video Server waiting for a
phone call to establish a point-to-point connection. Dial-out connection denotes an
active Video Server to dial out to the other end of a dial-up server or any Internet service
provider, abbreviated as ISP, to request a point-to-point connection.
Cable connection
Null modem mode
- 15 -
Shut down the peripheral devices prior to connection and keep the power adaptor
unplugged until other cables are firmly connected. In the environment without Ethernet,
administrators can use the included null modem cable to connect to Video Server directly
and access point-to-point. After necessary information is entered and saved, turn off
Video Server and remove the null modem cable. Follow the installation of modem mode
in next paragraph to connect to Internet. Note Video Server will not really reset system
where it is used to in null modem mode.
Modem mode
If users have setup a rem ote dialup server or subscribed to an ISP service, Video Server
can be configured to dial to the server upon user-defined events. Otherwise it will wait
permanently for the user’s call to establish a network connection to provide services.
Before installation, make sure the necessary dialing information is correctly setup via
Ethernet or null modem connection.
Power on
Make sure all cables are correctly and firmly connected. T urn on cameras, sensors, alarm
devices, and then finally attach the power adaptor of Video Server to the electric power
outlet. Since most automatic detections of hardware perform when the system starts,
Video Server should be turned on after all peripherals are turned on and ready.

Server.
If an error message indicates a hardware error while connecting for the first time,
especially in Microsoft Windows 2000 environment, try again to recovery the possible
detection failure.
- 21 -
First access to Video Server in null modem mode
Through direct connection by null
modem cable, administrators can
connect to “http://200.1.1.1” in
the web browser. “200.1.1.1”
will be the default IP address of
Video Server in dial-in connection;
“200.1.1.100” will be the given
IP address for the user's PC by
Video Server. The user name and
password are the same as what
was entered during software
installation.
After successful authentication, administrators should see the motion pictures in the
main page. When using Microsoft Internet Explorer, administrators must allow installing
a plug-in provided by Video Server additionally prior to viewing motion pictures.
Change initial password of administrator
For best security, administrators must change the password on the security page of
configuration immediately. After changing the password, the browser will display the
authentication window again to confirm the new password.
Manage user privilege
Administrators can add up to twenty user profiles in the Security option. While Video
Server accepts dial-in connection and acts as a server , the user name and password used
in dialing are the same as what is stored in the user database managed for web access.
Any managed user can be authorized during PPP negotiation and access web pages.
However, only administrators can access the configuration page.
Complete network settings
Basically the null modem is used to setup the later attached modem where Eth ernet i s
not available. Refer to the modem setting in the COM2
section for details about ISP
information. After everything is set and saved, turn off Video Server and replace the null
modem cable with modem for dial-up network. Since the null modem connection is used
to configure Video Server in advance for modem connection, administrators cannot
connect again without restarting the system.
- 22 -
First access to Video Server in modem mode
If the dial-out is not prohibited and the attached modem is recognized, Video Server will
send out the system startup log and connection log by email or FTP according to user’s
settings as soon as the system is ready. That can be used to verify if the settings work.
Then Video Server will always wait for someone to dial in. To dial in Video Server, setup
a connection in dialup network on PC where the phone number is the phone line of Video
Server. After connecting successfully, start the Web browser and connect to
“http://200.1.1.1” . In this case, Video Server runs as a dial-up server and assigns the IP
address of “200.1.1.100” to the PC at the other en d. While seeing the authenticatio n
message window, type “root” as user name and the serial number of Video Server as the
initial password. The point-to-point connection allows users connecting Video Server for
surveillance at any time.
If the administrator has setup some conditions in the application Web page or the script
file, Video Server will automatically dial out based on the administrator's configuration.
Refer to the Application
section in the Chapter Definitions of Configuration for special
security applications.
- 23 -
How to Use
Open your familiar web browser and connect to Video Server just like a general web site
and the video will present on demand. Make sure the web address of th e target Video
Server is accurate.
Authentication
After opening the Web browser and typing in the URL of Video Server, a dialogue window
will pop out to request a username and password. For administrator’s initial usage of
Video Server, enter the username as “root” and the password as the serial number in
capital letters. The serial number can be found on the labels under the body of Video
Server and the top side of the carton. The primary users will be allowed to enter as soon
as the administrator finishes adding user profiles. Upon successful authentication, the
main page will be displayed.
For demonstration purpose, enter the Demo
Web page of configuration to activate the
demo account and choose permitted services. Once the demo account is setup, any one
may watch the video by using “demo” as user name while ignoring the password.
Different from primary users, the demo account has certain limitations that are
determined by administrators.
In the figure, the foreground is the
login window and the background
shows the message when
authentication fails. The user may
check the option to save the
password for future convenience.
- 24 -
Installing Plug-in
If it is initial access to Video Server via the Web browser supporting server push, the
motioned pictures will display directly. If the Web browser is Internet Explorer in
Windows, users will be asked to install a new plug-in that is provided by Video Server.
This plug-in has been registered for certificate and is used to display motioned pictures
in the Internet Explorer. Users may click on
to install the plug-in. If th e web
browser does not allow the user to instal l, check the security option to lower se curity
levels or contact network supervisors.
- 25 -
Main Page
Basic functions are displayed in main entrance page of Video Server. The first figure
below is graphic mode that has better visual effect and the second one is text mode that
will shorten download time. The main page may look differen t depending on the PTZ
driver or the privilege of the user.
Graphic mode
Text mode is
default if any
image button is not
available.
Text mode
- 26 -
Video input selection
Switch the video source among up to four ca meras connected to Video Server. When
clicking on the quad display button, a special quad display of all video inputs is available
for simultaneous monitoring. The picture refresh rate of quad display is slower than the
single input because it takes time to capture the valid image after changing the video
source. The actually appearing buttons depend on the system settings.
Video quality selection
It allows users to adjust the video quality for speed or smoothness. The performance is
also subject to the network bandwidth and the number of users. Five options are
available to be chosen from “Medium” to “Excellent”. “ Medium” quality means the
picture has the quickest refresh rate but the worst image quality and “Excellent” quality
means the picture has the slowest refresh rate but the best image quality.
Video size selection
It allows users to adjust the image size with consideration of bandwidth and image
resolution. Five options are available including “Half”, “Half×2”, “Standard”,
“Standard×2” and “Double”. “Half×2” consumes the same bandwidth as “Half” but
has the same size with “Standard”. Of course the visual effect is worse than “Standard”.
“Standard×2” compared to “Double” is similar to the case. “Half×2” is especially suits
in the low bandwidth environment like a dial-up network. T o fit into the small image area,
timestamp will be skipped in “Half” and “Half×2” modes.
While in the quad display mode, “Half” means the image is composed of half size image
of each channel. “Standard (fast)” will have higher frame rate and “Standard (clear)”
will have higher resolution image.
System configuration
There is a button or text link under video buttons for system configuration that only
appears in administrators’ main page.
External digital output control
There may be two remote control buttons for each digital ou tput on the main page. If
there are external devices attached to digital outputs, administrators or permitted users
