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, the IT401 Video Server will utilize the Ethernet
interface prior to the modem attached to COM2.
COM port
This RS232 serial port can connect with a modem or included null
modem cable to utilize dial-up network when Ethernet is not available. If the
IT401 Video Server operates with Ethernet interface, administrators may use
this port to control PTZ camera attached to VIDEO.

6 ß RS485 A (non-inverting)
The IT401 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.
The IT401 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.
Restore button
There is a button hidden in the box for restoring the system factory
default settings. 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 the
IT401 Video Server.
The power adapter of the IT401 Video Server
and the external power supply are prohibited to
exist together. Only one source can feed power to the
IT401 Video Server. Improper usage will result in serious damage.
To easily fit into various
environments, the IT401 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.
The IT401 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 the IT401 Video Server and "administrator" means the supervisor who has the root password
to configure the IT401 Video Server in addition to general access.
Administrators should carefully read this manual, especially during
installation.
Hardware installation
Before installing multiple IT401 Video Servers 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 the IT401 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 the IT401 Video Server.
Turn on cameras, sensors, alarm devices, and then attach power adaptor of the
IT401 Video Server to the electric power socket. After the POST (power-on self
test) is complete and the result is successful, the IT401 Video Server is ready
for software configuration as described in this manual. At this stage, network
speed and video modulation type are automatically detected.
Software installation
Easy way with installer program
In order to configure the IT401 Video Server remotely,
administrators should keep the serial numbers of the new IT401 Video Server for
identification and initial passwords. After successfully mounting the IT401
Video Server in the proper position, run the Installer program on the PC in the same network to locate the
newly mounted IT401 Video Server. The IT401 Video Server also supports manual
setup procedures to non-Windows based environments. The manual procedure is
described next.
After the POST is done, the IT401 Video Server will try to configure
itself by detecting the network environment. If there is DHCP service over the
network, the Installer program
will catch the given information, then display the serial number and given IP
address for each IT401 Video Server as the figure above. To install the IP
address, follow the steps.
1Click on the entry with the serial number you want to install. If
the "Assigned" field of
the entry is labeled "Yes",
that means the IT401 Video Server has already been installed.
2Type the desired IP address if it is other than the IP address given
by the DHCP server.
3Check the box to fix the IP address of the IT401 Video Server.
Otherwise the IT401 Video Server will lose the network address at next system
boot and you have to run this installer again.
4Click 
to progress the installation.
5After successful notification, administrators may keep the address
information and click directly on 
to access the IT401 Video Server in the
default browser.
If the IP address is taken by another network device in the network,
the Installer program will pop out another message window to warn that the
assigned IP conflicts. In this case, administrators should ask the network
supervisor for a vacant IP address.
While ¡§Use this IP whenever
system boots", is checked, a dialog window may pop out to ask for ¡§Server FTP Port¡¨ and ¡§Root Password¡¨ because they are already
changed by administrators to other than default settings. If the original settings
are lost, restore default settings and run software installation again.
Once the installation is complete, administrators should follow the First
access to the IT401Video Server section for necessary checks and
configurations.
Manual way with existing programs
For those environments such as MAC, Linux, Unix or other operating
systems, whose installer is not yet available, some common network tools
including ARP and PING can be used to install the IT401 Video Server. Before
proceeding further, make sure ARP and PING
programs exist.
First, type arp ¡Vs ¡§assigned IP address¡¨ ¡§Ethernet address¡¨
to add an entity in the system¡¦s name table. The Ethernet address is identical
to the serial number of the IT401 Video Server and should be typed in the
appropriate format like ¡§uu-vv-ww-xx-yy-zz¡¨ or ¡§uu:vv:ww:xx:yy:zz¡¨, which
depends on the operating system.
Once the name entity is added, type ping "assigned IP
address¡¨ to invite the new IT401 Video Server. If it replies, that means the
IT401 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 the IT401 Video Server. Since the accurate grammar of ARP and PING
depends on the operating system, refer to its related help manual.
Example of DOS prompt in
Windows 2000
First access to the IT401 Video Server
Change initial password of administrator
Starting the Web browser to connect to the assigned IP address of the
IT401 Video Server, users will be asked for user name and password by an
authentication message window. A root password, identical to the IT401 Video
Server's serial number, is needed for the initial access to a newly installed IT401
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.
Manage user privilege
For complete protection from illegal usage, the IT401 Video Server
provides three privileges and always needs user name and password before
access. The lowest level is DEMO mode whose services are subject to
administrator's permission. The standard level is the USER mode that consists
of twenty user profiles. Each user is able to access the IT401 Video Server
under the given privilege, 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¡¨.
Complete the network settings
Although the IT401 Video Server already can be accessed after
software installation in local area network, administrators should complete the
network settings in the configuration page. The complete network configurations
including subnet mask as well as the IP address of default gateway and DNS are
provided by your network administrator or Internet service provider. Once the
wrong network settings make the IT401 Video Server fail to work, refer to
Appendix A to restore factory default settings.
By default the IT401 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 in network configuration Web page or
Installer program.
Details about configurations are described in the relative category
of the Chapter Definitions of Configuration.
Modem Environment
Though the IT401 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, the IT401 Video Server
will detect if any external modem is connected to the modem port . As soon as a
modem is detected, the heartbeat LED will flash periodically. If no modem
responds, the IT401 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 IT401
Video Server waiting for a phone call to establish a point-to-point connection.
Dial-out connection denotes an active IT401 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
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 the IT401 Video Server directly
and access point-to-point. After necessary information
is entered and
saved, turn off the IT401 Video Server and remove the null modem
cable. Follow the installation of modem mode in next paragraph to connect to Internet. Note the IT401 Video Server will not really reset
system where it is used to in null modem mode.
Modem mode
If users have
setup a remote dialup server or subscribed to an ISP service, the IT401 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.
Make sure all cables are
correctly and firmly connected. Turn on cameras, sensors, alarm
devices, and then finally
attach the power adaptor of the IT401 Video Server to the electric power
outlet. Since most automatic detections of hardware perform when the system
starts, the IT401 Video Server should be turned on after all peripherals are
turned on and ready.
Software installation
Via Ethernet

5. Right-click on the newly setup connection icon for entering properties.
6. In the first General page, clear "Use area code and Dialing Properties" option and click
on 
.
7. Select 115200 as the speed and click on .
8. On the second page, only check "Enable software compression" and "TCP/IP" while leaving others
blank. Keep other settings as default values and click on .
Now the connection is ready to use for null modem. Double click the
newly setup connection. A dialing information window will pop up. Enter ¡§root¡¨ as user name and the serial
number labeled on the bottom side of the box as the password and click on 
.
Notice that the letters in the serial number should be capital form. For
example, type 'A' instead of 'a'. After some negotiation prompts, a connection
status window will show the speed is 115200 bps.
After connection is established successfully, go to the next
section, First access to the IT401 Video 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.
First access to the IT401 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 the IT401 Video Server in dial-in connection; ¡§200.1.1.100¡¨ will be the given IP
address for the user's PC by the IT401 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 the IT401 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 the IT401 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 Ethernet is not available. Refer to the modem setting in the COM section
for details about ISP information. After everything is set and saved, turn off the
IT401 Video Server and replace the null modem cable with modem for dial-up
network. Since the null modem connection is used to configure the IT401 Video
Server in advance for modem connection, administrators cannot connect again
without restarting the system.
First access to the IT401 Video Server in modem mode
If the dial-out is not prohibited and the attached modem is
recognized, the IT401 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 the
IT401 Video Server will always wait for someone to dial in. To dial in the
IT401 Video Server, setup a connection in dialup network on PC where the phone
number is the phone line of the IT401 Video Server. After connecting successfully,
start the Web browser and connect to ¡§http://200.1.1.1¡¨.
In this case, the IT401 Video Server runs as a dial-up server and assigns the
IP address of ¡§200.1.1.100¡¨ to the
PC at the other end. While seeing the authentication message window, type ¡§root¡¨ as user name and the serial
number of the IT401 Video Server as the initial password. The point-to-point
connection allows users connecting the IT401 Video Server for surveillance at
any time.
If the administrator has setup some conditions in the application
Web page or the script file, the IT401 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.
Open your familiar web browser and
connect to the IT401 Video Server just like a general web site and the video
will present on demand. Make sure the web address of the IT401 Video Server¡¦s
target is accurate.
After opening the Web browser and typing in the URL of the IT401
Video Server, a dialogue window will pop out to request a username and
password. For administrator¡¦s initial usage of the IT401 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 the IT401 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 Security 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.
If it is initial access to the IT401 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 the IT401 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 the web
browser does not allow the user to install, check the security option to lower
security levels or contact network supervisors.
Basic
functions are displayed in main entrance page of the IT401 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 different
depending on the PTZ driver or the privilege of the user.
Graphic mode
Text mode
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¡Ñ2¡¨,
¡§Standard¡¨, ¡§Standard¡Ñ2¡¨ and ¡§Double¡¨. ¡§Half¡Ñ2¡¨
consumes the same bandwidth as ¡§Half¡¨ but has the same size with ¡§Standard¡¨.
Of course the visual effect is worse than ¡§Standard¡¨. ¡§Standard¡Ñ2¡¨
compared to ¡§Double¡¨ is similar to the case. ¡§Half¡Ñ2¡¨ is
especially suits in the low bandwidth environment like a dial-up network. To
fit into the small image area, timestamp will be skipped in ¡§Half¡¨ and ¡§Half¡Ñ2¡¨
modes.
System configuration
There is a button or text link in the
left side of the system configuration that only appears in administrators¡¦ main
page.
External digital output control
There may be two remote control buttons
for the each digital output on the main page. If there are external devices
attached to the digital output, administrators or permitted users can click on 
to short ¡§Common¡¨ and ¡§Normal Open¡¨ pins
of the digital output or click on 
to short ¡§Common¡¨ and ¡§Normal Close¡¨ pins
of the digital output. To know more about the digital output for external
devices, refer to the rear panel introduction of the Chapter Physical
Description.
Motorized camera control
If there is any serial device like
motorized camera attached and correctly setup to the COM port, the control panel will appear
on permitted users¡¦ main page. The effective buttons will change color when
users move the cursor over. Users can control the motorized camera in pan and
tilt direction as well as zoom and focus. The home button can return the camera
to the center position if the camera supports this command. Besides the near
and far control in focus, an ¡§AUTO¡¨ button is provided for setting auto focus
mode. To move the motorized camera more precisely, speed control of pan and
tilt allows users to fine tune the aiming position. Users also can directly
click on any point in the image to force the motorized camera to focus on it.
Users can pull down the list of preset locations to choose any one to move the
camera to the preset location that is pre-defined by administrators. The
detailed configurations are described in the related section in the Chapter Definitions
of Configuration.
Custom camera commands
There are at most five buttons of custom commands for users to
control the attached motorized cameras in addition to the default pan, tilt,
zoom and focus control. The custom commands mean that administrators can setup
some special commands like activating or deactivating the wiper of dome according
to the user¡¦s manual of the attached motorized device.
System Configuration
The system configuration can be easily done remotely on Internet
Explorer through the Web interface. There are two wizards in addition to
classified categories of system configurations. They can give friendly
instructions and facilitate the setup job. Alternately administrators may type directly
the URL of system configuration, ¡§http://<IP
address of of the IT401 Video Server>/setup/config.html¡¨, to directly
enter the configuration page. If administrators also want to set certain
options through the URL, read the relative section in the Chapter Advanced Usage
for reference. The IT401 Video Server also supports FTP to modify the system
configuration file, CONFIG.INI, for technical usage. The details are described
in the Chapter Advanced Usage.
Since it is a networking video server, administrators should run ¡§Setup wizard¡¨ or well configure ¡§Security¡¨, ¡§Network¡¨ and ¡§Video¡¨ at
least. To support external serial port devices, configure ¡§COM port¡¨ and then ¡§Camera
Setting¡¨ in ¡§Video¡¨. To utilize
the built-in features of security and web attraction, run ¡§Application wizard¡¨ or configure ¡§Application¡¨ and ¡§Demo¡¨.
Besides these features, administrators can adjust the system date and time in ¡§System¡¨, or have different homepage
layout by configuring ¡§Homepage layout¡¨.
The IT401 Video Server also provides some system maintenance like ¡§View log file¡¨, ¡§View parameters¡¨ and ¡§Factory
default¡¨.
The setup wizard will guide administrator to enter necessary
information including system name, current date and time, administrator¡¦s
password, video configuration and captions, and network settings.
Administrators can exit the procedures anytime to reserve the current configuration.
Finally the setup wizard will ask for reboot to validate the changes and
administrators can decide to reboot later.
There are two main applications including surveillance system and
web attraction by means of the IT401 Video Server. The former one will utilize
the built-in motion detection and external sensors to integrate with the
existing e-mail or FTP server or external alarms to constitute a security
system. It also possesses the weekly schedule for timed monitoring. The later
one will customize the main page to your personal style and setup accounts for
your possible visitors. The application is perfectly constructed and performed
on several clicks by your fingertip. Administrators can additionally configure
the application parameters in the Application page of configuration for
more advanced usage after using Application wizard.
System parameters
Change host name
The ¡§host name¡¨ is used
for the homepage title of main page and displays as the title over the video
window on the main page. The maximum string length is 40 characters or 20
characters in double-byte-character-systems like Chinese or Japanese.
Adjust date and time
There are three ways to adjust system date and time. The easiest is
to make the IT401 Video Server "Sync with computer time". The
second ¡§Manual¡¨ is to set the date and time manually by entering new
values. Notice the format in the related field while typing. The third ¡§Automatic¡¨
is to make the IT401 Video Server automatically synchronize with timeservers
over the Internet every month. It may fail if the assigned NTP server cannot be reached or the IT401 Video Server is within a
local network. Leaving the NTP server blank will let the IT401 Video Server
connect to default timeservers. Domain name or IP address format is acceptable
as long as DNS server is available. Do not forget setting the "Time
zone" offset for local settings. Refer to the Appendix G for the time
zone of your region. It only affects the hour in NTP method.
Once the settings are changed, click on 
to validate changes.
Security privilege
Change root password
To change the administrator¡¦s password, type the new password in
both text boxes identically. What is typed will be displayed as asterisks for security
purposes. The maximum password is 16 characters. After pressing 
, the
web browser will ask administrators for the new password for access.
Add new users
To add a new user, type the new user's name and password, check
respective privilege, and then press 
to insert the entry. There are a total of
twenty user accounts. Each user can have independent access right of the video
channel, external I/O access and camera control.
Edit user¡¦s privilege
If the permitted rights of some user has to be changed, pull down
the user list to find the user name and press 
. A
new window will pop out for administrators to change password and choose
different privilege.
Delete existing users
To delete a user, pull down the user list to find the user name to
be deleted and press 
. A
message window will pop up for confirmation.
Enable snapshot mode for more users
The maximum users that can view the IT401 Video Server at the same
time are twenty. Administrators can check ¡§Allow
more guests with snapshot mode¡¨ to enable the snapshot mode for more users.
Then the users over twenty will have the main page with snapshot mode instead
of normal motion picture. It is practical for web attraction. In such case,
configure the ¡§Snapshot interval¡¨ to
achieve better performance. The bigger interval between snapshots, the more
users can have snapshot mode work.
Demonstration account
To setup the IT401 Video Server for demonstration to the public,
administrators need to choose the service(s) to be permitted. After checking ¡§view¡¨ in Security page , users may use ¡§demo¡¨ as general user name and
password is not required. Administrator also can assign the ¡§Control Camera ¡¨
or ¡§ Control Do¡¨ option to demo
accout.To separate the demo account from primary users can prevent from interfering
with the normal operations.
Network settings
Fix the IP address
To eliminate incautious mistakes during installation, the IT401
Video Server will stay in installation mode whenever it starts unless "Reset
network at next boot" is disabled. This option can also be disabled
using the Installer program. Once the option is disabled, the IT401 Video
Server will skip installation at the next boot and the Installer program will
not find the installed units. That implies that the IT401 Video Server cannot
be accessed if no one remembers the IP address, except for restoring factory
default settings. However, with this option disabled the IT401 Video Server can
automatically operate normally after restarting in case of losing power. This
option is ignored in the PPP connection.
Basic network settings
Administrators may need to modify the network settings to fit into
existing networks. The subnet mask in some broadband service may differ from
the default value 255.255.255.0 and service providers may assign more specific
network settings. Administrators should change the configuration to what given
by the service provider. The configuration may include "IP address",
"Subnet mask", "Default router", "Primary
DNS server" and "Secondary DNS server". After
changing network settings, be sure to leave "Reset network at next boot"
blank to skip next installation when the system restarts. Otherwise those
network settings will be erased at the next start.
Bandwidth utilization limit
Each IT401 Video Server can be limited in bandwidth utilization by
administrators according to its priority and importance of location. "Bandwidth
limit" is most useful to balance network utilization when multiple
IT401 Video Servers are installed in the same network. It is more effective
than changing image quality only and achieves better performance with adequate
image size and quality.
Changing port number of servers
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. Administrators should have enough network knowledge to
change the default port.
E-mail settings
The IT401 Video Server not only plays the role of server, it will
also actively connect to servers outside to send out messages or snapshots.
When the IT401 Video Server starts, it will send out a system log via e-mail as
long as the settings are correct rather than upload it via FTP. Even in modem
application, the IT401 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, the IT401 Video
Server will send out snapshots once conditions are met. To activate e-mail
function, enter correct settings of "SMTP (mail) server" and
"Recipient email address". "Secondary SMTP (mail)
server" and "Secondary email address" are provided
for backup connection when the primary one fails. ¡§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.
FTP settings
To send the log files described in the above paragraph via FTP, the
SMTP server should be erased. Administrators must enter correct "Primary
FTP Server", "Primary FTP user name" and "Primary
FTP password". "Primary FTP remote folder" is the
relative sub-folder in the remote FTP server. If the port of the remote FTP
server is changed other than 21, set the real port to ¡§Primary FTP server
port¡¨. If the local network is protected by a firewall to prevent from
initiating FTP connection from the remote FTP server, you may be able to
connect to the FTP server but unable to put any file due to data channel connection
failure. Check ¡§Primary FTP passive mode¡¨ for passive
transfer solution. Another set of "Secondary" server settings
is also provided for backup connection.
In either e-mail or FTP, the primary server information should be
entered first. If the primary server is not set, the related FTP or email will
be cancelled. 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.
After everything is set, click on . A
warning message will pop out for confirmation. After clicking on 
, the
IT401 Video Server will automatically restart. If "Reset network at
next boot" is kept checked, perform software installation again.
Otherwise the IT401 Video Server will boot up according to the new
configuration automatically.
Any change made to this page will make the
system restart to validate. Make sure every field is correctly typed before
clicking on . If
the IT401 Video Server fails to response due to erratic settings, perform the
restore procedures and run software installation.
Administrators should notice that the basic network settings
including IP address, subnet mask, default router and DNS servers will be
cleared when the network interface is switched to the other between Ethernet
and modem.
Video and motion detection
Adjust image settings
"Time stamp" and "Text on image"
will be enclosed in image for reference. The timestamp is captured from date
and time of the IT401 Video Server that is maintained by an on-board real-time
clock. "Color" setting is independent of the connected camera
and ¡§B/W¡¨ option can speed up the
encoder a little. ¡§Default size¡¨
option here will be the default size of video window when users first connect
to the IT401 Video Server. ¡§Default quality¡¨ option here will be the default quality when users first connect
to the IT401 Video Server. And the "Modulation" type is
auto-detected during initialization, but administrators can still set it
manually. To adjust image settings for best visual quality, press 
and a motion picture window will pop up
for your reference. There are four fields including "Brightness",
"Contrast", "Hue"
and "Saturation" for video compensation. Each field has eleven
levels ranged from -5 to +5. While adjusting, administrators can click on 
to check prior to 
the setting in memory. If the adjustment
is not good, administrators can click on 
to restore the original settings without
change. After configuration done, click on 
to close this window. If parameters are
changed without saving, they will be used until the next system startup.
Configure motion detection
The channel can
have its own settings of motion detection independently. The settings including
¡§Object size¡¨ and ¡§Sensitivity¡¨ allow administrators fine
tune to fit into the environment. The ¡§Object
size¡¨ decides the space ratio of motioned objects over the monitored
screen. The ¡§Sensitivity¡¨ sets the
measurable difference between two
sequential images that
would indicate motion. The larger object size and lower sensitivity will make the
IT401 Video Server ignore small variations in images. While the motion
amplitude of some object in the monitored screen is over the settings, a white M in red background
will indicate at the upper-right corner of the window.
Motion detection is provided as reference
because it is very environment-dependent Especially working by the very
sensitive settings, some triggered events may be considered as false alarms though there is tiny
difference happening indeed. It can be affected by florescent light flashing,
shadow shifting, and so on.
COM port configuration
Choose serial interface
There are two types of serial interfaces supported by COM port but
only one interface can be used at one time. Administrators must set the correct
¡§Interface mode¡¨ between RS232 and
RS485 according to the attached device.
Choose device driver
If the attached device is PTZ driver, administrators should select
the appropriate PTZ model. Refer to our Web site for newly supported PTZ
drivers. If the attached PTZ camera is not in the support list, administrators
can select ¡§Custom Camera¡¨ to enter
the proprietary commands for pan, tilt, zoom and focus control. If it is not a
PTZ camera but another serial device like video multiplexer, administrators can
select the ¡§Generic CGI command¡¨ to
control the device via CGI commands. See the URL of External Device Control
section in the Chapter Advanced Function for details.
COM port configuration
After saving the driver type, the COM port configuration will show
up for entering the correct settings that depends on the camera type. Refer to
the Appendix Settings for Supported PTZ Cameras for default settings of
supported PTZ camera including baud rate, data bits, stop bit and parity bit.
Custom commands
The IT401 Video Server provides five more custom commands other than
general pan, tilt, zoom and preset functions. Administrators can click on 
and refer to the instruction manual of
the attached device to setup frequently used functions. The "Command"
should be entered in ASCII format; the IT401 Video Server will translate it
into binary code and send it out through the serial port. For instance, a text
string of "8101ABCDEF" will be translated into five bytes of
hexadecimal 81, 01, AB, CD and EF. The maximal length of a command string is 60
which is equivalent to 30 hexadecimal bytes. "Display string"
is for text on command buttons and should be less than 8 characters. If the ¡§Custom Camera¡¨ is selected, there will
be more commands for PTZF regarding to the custom camera.
ISP information setup
In PPP interface, a modem option will show instead of camera control
2. Configurations include modem initialization and outside dial-up server. If
the users will setup with external sensors and alarms for property security,
dial-out is needed to send some snapshot-attached e-mails when the preset
conditions are triggered. In such applications, also remember to choose Network
option to enter mail server address and recipient's e-mail address. If "Dialout
allowed" is not checked, the IT401 Video Server will not send out any
snapshots when events occur and the settings except for "Initial modem
command" in this page will have no effect. The system will preset the
attached modem to eliminate echo and mute line sound. To initialize the modem
with further commands, type into the edit box. The prefix "AT" should
be included.
Administrators should choose an appropriate "Dial Method"
according to the local POTS environment. An incorrect dialing prefix may cause the
IT401 Video Server to fail when dialing out. "Redial attempts"
means how many times the IT401 Video Server should try to connect to each ISP.
Setting the value in "Disconnect after minutes" will force the
IT401 Video Server to drop the connection when there is no activity on the
connection for the specific period. The range of this period is from 1 to 240
minutes, with 0 indicating a continuous connection. Administrators may let the
IT401 Video Server keep the connection for a while to allow connections from
outside. The IP address given by the ISP can be taken from the connection log
that is mailed or uploaded when dial-up connection is successful. Setting the
value to zero will make the IT401 Video Server always keep the connection.
Based on the settings of DI/DO in the application, the system will
send mails or upload via FTP with image attachment upon the event occurring. In
that case the IT401 Video Server will need a network connection and
automatically dial out to the pre-configured server outside. When a connection
is successfully established, the IT401 Video Server will send out a connection
log to notify given network settings. For those installations that may switch
the network interface between Ethernet and PPP, administrators should notice
that the settings of FTP or SMTP servers might be different from what are in an
Ethernet environment. If the network interface is changed, administrators may
need to configure them in advance.
The IT401 Video Server will try the second ISP as a backup when the
first ISP fails and exceeds the redial attempts. "ISP phone number"
should be the complete phone number including country code and area code if
necessary. "Login username" and "Login password"
are used to pass the PPP negotiation requested by the ISP server. Note that the
pair of login name and password is dependent on the ISP and is different from
what is used in the authentication process in web access.
Application constitution
Administrators can use combinations of options on the application
page to perform many useful security applications. The IT401 Video Server
provides two application modes; one is performed according to the settings on
the web page, the other is performed according to the external command script.
Though most settings will automatically be done by the Application Wizard,
administrators still can adjust the settings from this page.
Weekly schedule
A useful weekly schedule is provided for daily security application.
Administrators can select weekdays from Monday to Friday with the daily schedule
from 9:00 am to 6:00 pm that no one is at home to perform any event checking.
If the security system needs to be installed in office that no one is there
during the nights or weekend, administrators just set the time period as above,
then check ¡§All the time except for the
above schedule¡¨ for opposite operations.
External command script
Administrators can write a script named SCRIPT.TXT to perfectly match the additional software according to
the Command Script for Complex Applications section in the Chapter Advanced
Functions. After uploading this script to the IT401 Video Server via FTP,
check the option ¡§Enable the external
script file to exclude the following settings¡¨. Otherwise the IT401 Video
Server will operate according to the settings below.
Event operation
The IT401 Video Server provides general options for two basic
applications, event operation for
security and sequential operation
for web attraction. In event operation, administrators have to setup some
conditions to check and some actions to happen consequently. The conditions
include motion detection and the status of digital inputs. While checking ¡§Detect
motion¡¨ box, administrators should click
¡§Motion Detection¡¨ button on Video page or click ¡§Motion
Detection¡¨ link in Applicatoin page
to configure the appropriate parameters. In the newly opened window,
percentage of object size
over whole window and sensitivity
can be fine tuned to fit into the environment. If any
motion is over the settings, an ¡¥M¡¦ will appear on the upper-right
corner of image for indication. The ¡¥M¡¦ will appear in the image to indicate some motion
is detected as long as ¡§Show alert in
image¡¨ is checked. If there are any sensors attached to the digital inputs,
administrators can set the state to fire alarm. There are four states of ¡§Input
is High¡¨, ¡§Input is Low¡¨, ¡§Input is Rising¡¨ and ¡§Input is Falling¡¨. The edge trigger like ¡§Rising¡¨ or ¡§Falling¡¨
is generally used to detect the emerging signal from the external sensor. Once
any event happens, administrators can select ¡§Delay second(s) after event¡¨ option to drive some device attached
to the digital outputs several seconds after the event happens and/or send
snapshots that are taken right at the moment. . If administrators want to
receive some snapshots to check the event,
please check the ¡§Upload snapshot
while input condition match¡¨
box to get snapshots when inputting condition is matched the setting or
check the ¡§Upload
snapshots while motion detected¡¨ box to get snapshot when motion has been
detected. The IT401 Video Server will take three
snapshots of pre-event, the moment of event, and post-event for video channel.
Three snapshots of the channel can also be downloaded via FTP or HTTP URL.
Refer to the Download Event-triggered Snapshots section for details.
Sequential operation
With this feature, the IT401 Video Server can upload snapshots
periodically to external server as a live video source. The interval can be set
from tenth second to several hours. The external server must be setup correctly
in the Network configuration page.
Sending method
Either event mode or sequential mode can select one method between email and FTP. The companied external server must be setup correctly in
advance. If email is chosen, the snapshots of the video channel will be
attached in the emails. If FTP is chosen, administrators can choose to add date
and time in the file name of snapshots. If the snapshots are used as the live
video source, the date and time suffix can be eliminated to update the same
source file.
The option ¡§Show alert in image¡¨ may be set when running application
wizard or configuring motion detection. Administrators should manually uncheck
it if no indication of motion detection is needed in the image.
Homepage layout
There are two homepage display modes. One is "Image mode"
that uses graphics for links; the other is "Text mode" that
mostly uses text for links.
Administrators may easily give the IT401 Video Server a different
presence of homepage. The "logo graph" for the system logo at
the upper-left corner can be hidden; or the default image from the system
memory can be used; or an external resource can be used by assigning a URL. The
"Background graph" is similar. Default images of the system can
be customized but limited by memory size. Images from external resources can be
larger and more beautiful but will need more time to load. If the background is
skipped, the background color will fill the browser window. Administrators also
can give the system logo a "Logo link" to connect to another
web site while clicked. The "Font color" and "Background
color" can be chosen from sixteen colors as you like. See the Customize
graphics in homepage section in the Chapter Advanced Functions for
how to replace the default images of log, background and buttons of video
switch.
If any necessary image is lost while homepage layout is image mode, the
IT401 Video Server will switch to text mode automatically.
View log file
There is some useful information in the system log including current
system configuration and activity history with timestamp for tracking.
View parameters
The whole system parameters will be categorized listed for
administrators to check. The content is the same as CONFIG.INI.
Factory default
It is used to restore the factory default settings. This means any
changes made before will be lost and the system will be reset to the initial
status as shipping out of the factory. After confirmation, the system will
restart and require the software installation to setup the network.
Capture Up-to-date Still Images
Get snapshot via URL
Administrator and users can use the specific URL to capture the
current still image.
|

Get snapshot via FTP
Administrator and users can log-in the FTP daemon of the IT401 Video
Server to download the refreshed JPEG image named video.jpg. The user
name and password are as same as what in web access. The zero file size in file
directory means it is captured by request.

Download Event-triggered Snapshots
There are three video image files for the video channel of three
stages: pre-alarm, the moment when triggered and post-alarm. Only the snapshots
captured by the last event are preserved. Administrator and users can use FTP
or URL to get the saved snapshots. They can also be browsed from the application
page in system configuration.

Uploading Snapshots
Periodically
Upload snapshots to external FTP server
In sequential mode, the IT401 Video Server will send out snapshots
according to interval and period settings. If snapshot files are intended for
quick updates, it is better to skip date and time suffix. The file name will
then be video.jpg. If the snapshots are used for occasional monitoring, suffix
with date and time can help administrators classify them easily.
Send snapshots to external SMTP (email)
server
Comparing to the FTP method, email will induce more delay. But the
email can notify users for prompt action.
Customize Graphics in Homepage
While in text mode, there is a small icon named BTN_TEXT.GIF
preceding with each link that can be changed by administrators. While in image
mode, the default method will use the image stored in Flash memory. The
followings are the referenced file name and size limitation of each stored
images. Administrators may customize preferred image under the size limit and
put to the specific name via FTP. Administrators can download the original
images before upload for backup.

Command Script for Complex
Applications
Besides the application wizard, the IT401 Video Server provides a
more professional command script for advanced applications. The command script
will be executed exclusively with the settings in Application page of system
configuration except for the weekly schedule. To build the advanced
application, follow the steps below.
1. Use any text editor to edit the appropriate command script
according to the command format. The script size cannot exceed 500 bytes.
2. Save the script as a file named ¡§SCRIPT.TXT¡¨.
3. Use FTP with administrator¡¦s privilege to upload the script file.
4. Enter the
Application page in system configuration to define the
time period in weekly schedule. If it is supposed to run any time, keep the

/cgi-bin/recall.cgi?recall=<position>
<position>: the text
string of a location that is preset in system configuration.
Refer to Camera preset configuration URL for preset function.
Transparent Remote Serial Driver
The IT401 Video Server provides a highly customized control support
to third-party serial interface devices aside from PTZ cameras. That means in
addition to setting up a custom camera with PTZF commands, users may utilize
this mode and introduce a customized homepage to transmit arbitrary
user-defined commands from user-side to the IT401 Video Server. The third-party
device connected to the serial port of the IT401 Video Server will receive the
same command sent by the originator. The user only needs to attach the command
in ASCII format after the special URL. The IT401 Video Server will parse the
commands and translate into binary code to send out.
Send command to device attached to COM port
/cgi-bin/senddata.cgi?data=123456,ABCDEF&flush=yes&wait=1000&read=6
This hyperlink will inform the IT401 Video Server to send out binary
format commands to COM with ¡§0x12, 0x34, 0x56¡¨ followed by ¡§0xAB, 0xCD, 0xEF¡¨.
Each comma separates the commands by 200 milliseconds. ¡§flush=yes¡¨ means the receive
data buffer of COM port must be cleared before read. Then read 6 bytes after
waiting for 1000 milliseconds. The read data can be up to 128 bytes and will
return as ASCII coded hexadecimal value, e.g., 0x41, 0x42, 0x43 read from COM
port will show in returned homepage as 414243 instead of ABC.
Download System Log via FTP
Besides viewing the system log from the web page, administrators can
download the system log file, SYSTEM.LOG, via FTP. To log into the FTP daemon,
enter ¡§root¡¨ as the user name and the same administrator¡¦s password used in Web
access.
Restart System via URL
/cgi-bin/reset.cgi
Restart the IT401 Video Server without warning.
Restore Factory Default Settings via URL
/cgi-bin/restore.cgi
The IT401 Video Server will automatically restart after restoring
factory default configurations.
Administrators can use FTP to configure the IT401 Video Server much
quicker than Web page especially for multiple targets. To configure system via
FTP, first download the parameter file, CONFIG.INI, to customize each field
according to the environment and then upload back to validate the new settings.
To log into the FTP daemon, enter ¡§root¡¨ as the user name and the same password
used when connecting to the Web server. The serial number of the IT401 Video
Server is the password for the initial access.
The file is composed of eight categories: [SYSTEM], [LAYOUT], [NETWORK],
[VIDEO], [SERIAL1], [SERIAL2], [ALERT], and [DEMO]. The category name in brackets
should be in upper case. The item name in angle braces should be in lower case.
Some items related to disable/enable should use the keywords ¡§YES¡¨/¡§NO¡¨. The
number zero entry in <user name> and <user password> is for
administrators, i.e. ¡§root¡¨. Basically the IT401 Video Server will restart
automatically as soon as the file is accepted. If administrators want to cancel
the reboot procedure, set the first item, <reset system> to NO. It will
take effect once only and always show YES in the download file.
A sample CONFIG.INI is attached below. The italic text
following each line describes the characteristic of the field and the
bold italic characters are the options of the field.
