Law in your country may prohi bit surveillance devices. Though Video Server is not only a
high performance surveillance system but also a networked video server, ensure that the
operation of such devices are legal before installing this unit for surveillance.
It is important to carefully check the contents with the "Package Contents" section after
opening the package. Understanding the physical description can prevent damage caused
by abnormal usage and reduce mo st problems during installation.
Basically Video Server is a network device and should be easy to use for those who a lready
have basic network knowledge. If there is a system error and it does not recover easily d ue
to erroneous configuration, check the section "Auxiliary buttons" to restore factory default
settings and run installation again.
Video Server has been designed for various environments and can be used t o build var ious
applications for general security or demonstration p urpose s. For standard applications, read
"System configuration" to understand all functions. To make the best usage of Video Server,
review "Advanced functions" to get creative ideas. To those professional developers, "URL
Commands of Video Server" will be a very helpful reference.

Video Server provides a very flexible general I/O interface to combine with the user’s security
devices such as sensors, alarms, lighting or door locks. The general I/O terminal block has six
pins for device control. These pins can be divided into two categories based on their functions,
including RS485 and digital inputs and outputs.
If the device connected to COM has an RS485 interface, wire two control lines to pin 5 and pin 6.
After switching to RS485 on the configuration page, the PTZ control commands will be directed
through pin 5 and pin 6. If the distance from the controlled device is too far to allow accurate
function, an external power source may be used to pull high the RS485 signal.
Video Server provides one digital input and one relay switch. Pin 1 and pin 2 can be connected
to external sensor and the state of voltage will be monitored according to the programmed
scripts in configuration. The relay switch can be used to turn on or off external devices.
Status LEDs
Each time Video Server starts, it will perform a Power-On Self Test, abbreviated as POST
hereafter, to examine every hardware module. As soon as the administrator plugs in the power
adapter, both LEDs under the network LED will flash one by one until the POST is done. If any
module fails, both LEDs will indicate to the users the error according to the pattern listed in
Appendix A. If the result is good, both LEDs will turn off for a while and then follows the pattern
below. Network interface depends on the peripherals including Ethernet UTP cable, modem or
null modem cable. If the Ethernet cable between Video Server and Ethernet hub is good, Video
Server will choose the Ethernet network. If Ethernet is unavailable but a operational modem is
connected, the network interface will be PPP with modem. If either of the above is not the case,
Video Server will try the interface of PPP with null modem.

Restore button
There is a button hidden in the box for restoring the system factory default setting s. When the
system fails to install or operates abnormally, use the included assistant stick in the package
and follow the following procedures to reset the system back to its original status.
Poke the assistant stick into the hole to press down on the restore button. Restart the system by
unplugging and re-plugging the power jack. While keeping the button pressed, the system will
perform POST twice rather than the usual once, which can be observed from the flashing LEDs.
After the system flashes the LEDs for the second time, withdraw the stick to release the button.
The system will have restored factory default settings at that moment.
Power adapter
Connect the power jack of the included power adapter. Connecting the power adapter should
be the last operation while physically installing Video Server.

How to Install
To easily fit into various environments, 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 need to plug and play without complicated
configurations.
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 common 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 settings to
start new installation.
In the following content, "user" refers to those who can access Video Server and "administrator"
refers to the supervisor who has the root password to configure Video Server in addition to
general access. Administrators should carefully read this manual, especially during installation.

Power on
Make sure all cables are correctly and firmly connected before turning on Video Server. Turn on
cameras, sensors, alarm devices, and then attach the 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. If the detection of
video modulation fails, administrators may change the setting on the configuration page. Refer
to the configuration section for further information.
Connect the power jack of th e power adapter to Video Server prior to plugging the utility
end into the utility power socket. It will reduce accidental electric surge shock.

Software configuration
Easy way with installer program
In order to configure Video Servers remotely, administrators should keep the MAC address of
the new Video Servers for identification and initial passwords. After successfully mounting
Video Servers in the proper position, run the Installer program on the appropriate PC to locate
the newly installed Video Servers. Video Servers also support manual setup procedures to
non-Windows based environments. The manual procedure is described next.
After the POST is done, Video Server will try to configure itself by detecting the network
environment. If there is DHCP service over the network, the Installer program will c atch the
given information and display the serial number and given IP address for each Video Server as
following figure. If no DHCP service is available, a previous IP address will be displayed instead.
In that case, it may be 0.0.0.0 for a brand new unit. When multiple units are mounted, there may
be several entries shown in the window. Administrators may click on each entry with "Assigned"
field labeled "No" to install sequentially.
DVS-301 User Manual v1.00

The IP address shown in "Current IP Address" field is for the administrator's reference. If the
administrator wants to use another IP address, modify the IP text field below the list window.
If the administrator wants to fix the IP address of the unit, check the option "Use this IP
whenever system boots" to skip future installation procedures. Otherwise the unit will need
installation whenever it is restarted.
When IP and options are O.K., click on
. A message window will pop open to inform if
the IP address is valid.
DVS-301 User Manual v1.00

Building Networks for People
If the IP is not taken by another network device in the network, the Installer program will
continue with the setup. Otherwise another message window will warn that the assigned IP
conflicts. In this case, administrators should ask the network supervisor for a vacant IP address.

After successful notification, administrators may keep the address information for user’s
request.

, the "Assigned" field will be labeled "Yes". Administrators may click
to access the newly installed server in the default browser.
While checking “Use this IP whenever system boots”, a dialog window may pop out to ask for
“Server FTP Port” and “Root Password” because they are already changed to other than default
settings. If the settings are lost, restore default settings and use installer to install again.
DVS-301 User Manual v1.00

Once installation is complete, administrators should follow the actions in the "First access to
Video Server" section for necessary checks and configurations. Experienced administrators
may use the customized config.ini script file to perform a quick setup via FTP. Detailed
procedure can be found on the section “One-shot fast configuration via FTP”.
To allow users to connect to Video Server through an easily memorized name, the
administrators must first configure the name server in his network. Here is an example: When
the administrator wants to set up Video Server with a fixed IP address and let users connect to
Video Server by typing a name instead of IP address, the administrator may reserve the IP from
DHCP service and assign it with name in the domain name service. During Video Server
installation, assign the ready IP address. After successful installation, users may access the
Video Server by the given name.

Building Networks for People
Manual way with existing programs
In addition to the provided installer program, some common network tools including ARP and
PING can be used to install Video Server. Open a DOS command prompt window to perform
the manual installation.
First, type arp –s “assigned IP address” “Ethernet address”
name table. The Ethernet address is identical to the serial number of Video Server and should
be typed in the appropriate format, with every two characters separated by a hyphen like
“uu-vv-ww-xx-yy-zz”.
Once a name entity is added, type ping "assigned IP address”
it replies, that means Video Server has accepted the assigned IP address and is ready for
access. The first several ping requests may fail during the self-configuration period of Video
Server.

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”.
When connecting to 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 MAC address, is
needed for the initial access t o a newly installed Video Server. The administrator mu st change the root
password immediately after the initial in stallation to ensure securit y. 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 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.
The software installation in the previous section only set the host IP address and default subnet
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 network
settings are sure to work all the time, disable the install option if this IP address is already
reserved for this Video Server. Clearing this option will skip the installation procedure during the
next power-up and use the previous settings. If the install option stays checked, Video Server
will perform the installation procedure every time the system boots up.
Details about configurations are described in the "How to Use" section. Related figures are
attached for easy reference.

Modem Environment
Hardware installation
Before installing Video Server, the administrator should memorize the MAC address on the
packages respectively for the initial passwords.
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 the modem port. Once 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 lower LEDs will turn on
until null modem connection is established.
If users have setup a remote dialup server or subscribed to an ISP service, Video Server can be
configured to dial to the server upon special events. Otherwise it will wait permanently for the
user’s call to establish a network connection to provide services.
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
Shut down the peripheral devices prior to connection. Connect the supplied cables from Video Server to
the related devices according to following steps. Note that power adaptor must be kept unplugged until
other cables are firmly connected. For the first access to Video Server without Ethernet, administrators
may use the included null modem cable to connect to COM for direct connectio n. It is al so con venient for
administrators to access Video Se rver th rou gh the null modem cable directly without modem or Ethernet
card. After necessary information is entered, a modem can be used to dial into the Internet.
Power on
Make sure all cables are correctly and firmly connected. Turn on cameras, sensors, alarm
devices, and then finally attach 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.
Connect the power jack of th e power adapter to Video Server prior to plugging the utility
end into a utility power outlet. It will reduce accidental electric surge shock.
