BNC video inputs “IN” & outputs “OUT”
The IT404 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 the IT404 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 resistance 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.
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 IT404 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 the IT404 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
The IT404 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. 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 the IT404 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 the IT404 Video Server and the external power supply are
prohibited to exist together. Only one source can feed power to the IT404 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 device is too far
to allow accurate function, an external power source may be used to amplify the RS485 signal.
Digital I/O control
The IT404 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 of voltage will be monitored
according to the programmed conditions on the configuration page or the external script
file. Both relay switches can be used to turn on or off
external devices. When the system starts up, COMMON of both relay switches will
be short with NC. A simple diagram of example is
shown below.
|
|
If DI1 in
configuration is set as rising to drive DO1 to high that
denotes COMMON of DO1 short with NO, then the bulb
will light when DI1 signal changes from 0V to 12V.
|
|
Power adapter
Plug the power jack of the included power
adapter to the IT404 Video Server. Connecting the power adapter should be the
last operation while physically installing the IT404 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 the IT404 Video Server and the external power supply are
prohibited to exist together. Only one source can feed power to the IT404 Video
Server. Improper usage will result in serious damage.
To
easily fit into various environments, the IT404 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
IT404 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 IT404 Video Server and "administrator" means the
supervisor who has the root password to configure the IT404 Video Server in
addition to general access. Administrators should carefully read this manual,
especially during installation.
Hardware installation
Before installing multiple IT404 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 IT404 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 IT404 Video Server. Turn on cameras,
sensors, alarm devices, and then attach power adaptor of the IT404 Video Server
to the electric power socket. After the POST (power-on self test) is complete
and the result is successful, the IT404 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 IT404 Video
Server remotely, administrators should keep the serial numbers of the new IT404
Video Server for identification and initial passwords. After successfully
mounting the IT404 Video Server in the proper position, run the Installer program on the PC in the same network to locate the newly mounted IT404 Video Server. The IT404 Video
Server also supports manual setup procedures to non-Windows based
environments. The manual procedure is described next.
After the POST is done, the IT404 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 IT404 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 IT404 Video Server has already been
installed.
Type
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
IT404 Video
Server. Otherwise the IT404 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 IT404 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 IT404 Video 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 IT404
Video Server. Before
proceeding further, make sure ARP and PING
programs exist.
First, type arp –s “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 IT404 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
IT404 Video Server. If it replies, that means the IT404 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 IT404 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 IT404 Video Server
Change initial password of administrator
Starting
the Web browser to connect to the assigned IP address of the IT404 Video Server, users will be asked
for user name and password by an authentication message window. A root password,
identical to the IT404 Video Server's serial number, is needed for the initial
access to a newly installed IT404 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 IT404 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 IT404 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 IT404 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 IT404 Video Server fail to work, refer to Appendix A to restore factory
default settings.
By default the IT404 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.
Though the IT404 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 IT404 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, the IT404 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 IT404 Video Server waiting for a phone call to
establish a point-to-point connection. Dial-out connection denotes an active
IT404 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 IT404 Video Server directly
and access point-to-point. After necessary information
is entered and
saved, turn off the IT404 Video Server and remove the null
modem cable. Follow the installation of modem mode in next paragraph to connect
to Internet. Note the
IT404 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 IT404 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. Turn on cameras, sensors,
alarm devices, and then finally attach the power adaptor of the IT404 Video Server to the electric power
outlet. Since most automatic detections of hardware perform when the system
starts, the IT404 Video Server should be turned on after all peripherals are
turned on and ready.
Software installation
Via Ethernet

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 IT404 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 IT404 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 IT404
Video Server in dial-in connection; “200.1.1.100”
will be the given IP address for the user's PC by the IT404 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 IT404 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 IT404 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 COM2 section for details about ISP information. After
everything is set and saved, turn off the IT404 Video Server and replace the
null modem cable with modem for dial-up network. Since the null modem
connection is used to configure the IT404 Video Server in advance for modem
connection, administrators cannot connect again without restarting the system.
First access to the IT404 Video Server in modem mode
If
the dial-out is not prohibited and the attached modem is recognized, the IT404 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
IT404 Video Server will always wait for someone to dial in. To dial in the IT404 Video Server, setup a connection in dialup network on PC where the
phone number is the phone line of the IT404 Video Server. After
connecting successfully, start the Web browser and connect to “http://200.1.1.1”. In this case, the IT404 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 IT404 Video Server as the initial password. The point-to-point connection
allows users connecting the IT404 Video Server for surveillance
at any time.
If the administrator has setup some
conditions in the application Web page or the script file, the IT404 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 IT404 Video Server just like a general web site and the video
will present on demand. Make sure the web address of the IT404 Video Server’s
target is accurate.
After opening the Web browser and typing in
the URL of the IT404 Video Server, a dialogue window will pop out
to request a username and password. For administrator’s initial usage of the
IT404 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 IT404 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.
If it is initial access to the IT404 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 IT404 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 IT404 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.

is not available.
Text mode
Video input selection
Switch the
video source among up to four cameras connected to the IT404 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. To
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 output on the main page. If there are external devices
attached to digital outputs, 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 outputs 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 either 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 the IT404 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 IT404 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 “COM1” and “COM2” 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 IT404 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 IT404 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 IT404 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 IT404 Video
Server automatically synchronize with timeservers over the Internet every month. It may fail if the assigned NTP
server cannot be reached or the IT404 Video Server
is within a local network. Leaving the NTP server blank will let the IT404
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 C 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 each 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 IT404 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.
Network settings
Fix the IP address
To eliminate incautious mistakes during
installation, the IT404 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 IT404 Video Server will skip installation at the next boot and
the Installer program will not find the installed units. That implies that the
IT404 Video Server cannot be accessed if no one remembers the IP address,
except for restoring factory default settings. However, with this option
disabled the IT404 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 IT404 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 IT404 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 IT404 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 IT404 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 IT404 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 IT404 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
IT404 Video Server will automatically restart. If "Reset network at
next boot" is kept checked, perform software installation again.
Otherwise the IT404 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 IT404 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, camera mapping and motion detection
Enable video channels
Only when the video source is "Enable",
the related link will be displayed in the main page. It is recommended to
disable the video inputs without camera to improve the refresh rate within quad
screen function.
There are three buttons for “Image setting”, “Camera setting” and “Motion
detection” regarding to each video channel. The details are described in later
paragraphs. The video “Modulation” can be automatically detected by the system
or manually selected by administrators. Administrators can choose any video
channel to be “Default video source” shown in the main page when users connect
at the first time.
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 IT404 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 quality” option here will
be the default quality when users first connect to the IT404 Video Server. “Default size” option here
will be the default size of video window when users first connect
to the IT404 Video Server. To customize for different camera, administrators can adjust "Brightness", "Contrast", "Hue" and
"Saturation" for video compensation of each channel. 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. To facilitate the settings of four video channels, administrators can
click on 
then every setting in this channel will
copy to other channels. Note that the “Text on image” may need to change for
each channel. 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 attached motorized camera
In
addition to configuring PTZ camera driver in COM1 or COM2 page, administrators
have to define the relationship between video channel and camera. If there is
any PTZ camera attached, administrators should select the “Camera type” as “PTZ camera”,
set the attached COM port and the ID of the PTZ camera. The ID is specific to
the camera and necessary for multiple camera control. Refer to the manual of
camera for ID settings. After clicking on , the preset function will
appear in the lower half of window. There are up to twenty positions can be
memorized. Administrators can move the camera and then enter the position name
and save. The old “Preset position”
can also be pulled down to delete.
The camera control will be
activated only when both the attached “COM” port and “Camera Setting” are
correctly configured. The camera ID may be relative to some DIP switch on the
PTZ camera. Administrators may need to read the manual of the PTZ camera for
specific information.
Configure motion detection
Each
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 IT404 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.
Set video
modulation
There
are basically two types of video modulation; one is NTSC and the other is PAL.
Administrators can select “AUTO” to make the IT404 Video Server automatically
detect the correct type.
Select default video source
Administrators
can choose video channel 1 to 4 or quad screen to be the default video source
on the homepage when users connect to the IT404 Video Server. If the
default video source is disabled in the user’s privilege, the prohibited screen
will display instead.
COM1 port configuration
Choose serial
interface
There
are two types of serial interfaces supported by COM1 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 IT404 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 IT404 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.
COM2 port configuration and modem
Choose device
driver
There
are three types of device drivers that can be attached to COM2. The modem is
supported by COM2 more than COM1 but only RS232 interface is supported.
Administrators should select the device driver and click on save, then the
related configuration will show in the lower half of the page. If the modem is
selected, ISP information is necessary.
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
will appear when administrators select
PTZ driver. The usage is similar to COM1. If administrators select “Modem”, refer to the next paragraph for
details.
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 IT404 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 IT404 Video Server to fail when dialing
out. "Redial attempts" means how many times the IT404 Video
Server should try to connect to each ISP. Setting the value in "Disconnect
after minutes" will force the IT404 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 IT404 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 IT404
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 IT404 Video Server will need a
network connection and automatically dial out to the pre-configured server
outside. When a connection is successfully established, the IT404 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 IT404 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
IT404 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 IT404 Video Server via FTP,
check the option “Enable the external
script file to exclude the following settings”. Otherwise the IT404 Video Server will operate according to the settings below.
Event operation
The IT404 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 on any video channel and the
status
of any digital inputs. While checking motion in video, administrators should
click on the monitored video channel 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 “High”, “Low”, “Rising” and “Falling”
plus “Disable”. 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 “DO action” and/or send snapshots that are taken right at the
moment. There is also a “Delay second(s)
after event” option to drive some device attached to the digital outputs
several seconds after the event happens. If administrators want to receive some
snapshots to check the event, select the snapshot channels and check “Send snapshot while trigger condition(s)
match”. The IT404 Video Server will take three snapshots
of pre-event, the moment of event, and post-event for selected video channels.
If the snapshots are not enough, more snapshots can be taken after the event by
configuring “Take snapshot(s)” and
the “interval after the event” in
unit of tenth second. Three snapshots of each 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 IT404 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 selected video channels 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.
Demonstration account
To setup the IT404 Video Server for
demonstration to the public, administrators need to choose the service(s) to be permitted. After checking “Enable demo
account”, users may use “demo” as
general user name and password is not required. To separate the demo account from
primary users can prevent from interfering with the
normal operations.
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.
Image mode
Administrators may easily give the IT404 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.
Text mode
The "video string" for video links can be modified with maximum 16 characters. That will
make
users more easily know where the cameras installed like “Main Entrance”, “Warehouse”
instead of “video1”, “video2”. The
camera control panel is also replaced by text buttons.
If any necessary image is lost while
homepage layout is image mode, the IT404 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.

Video Embedded in Customers’ Homepage
In additional to the URL, some scripts
should be added to download a plug-in for motion pictures. The following
example simply displays title text and a real-time video window in Internet
Explorer or Netscape. The user name and password should be configured in
advance. Those who are familiar with HTML can easily add more components or
rewrite a more vivid and useful homepage.

Download Event-triggered Snapshots
There are twelve video image files for four video channels 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.
