The IT50 Network Camera can be connected
either before or immediately after software installation onto the Local Area
Network. The Administrator should complete the network settings on the
configuration page, including the correct subnet mask and IP address of gateway
and DNS. Ask your network administrator or Internet service provider for the
detail information. By default the IT50 Network Camera requires the
Administrator to run installation every time it reboots. If the network
settings are to remain unchanged, disable the Install option. Refer to ¡§Network
settings¡¨ on the System Configuration page for details. If any setting is
entered incorrectly and cannot proceed to setting up the IT50 Network Camera,
restore the factory settings following the steps in the ¡§Troubleshooting¡¨
chapter of the Appendix.
The default Administrator¡¦s password is
blank and the IT50 Network Camera initially will not ask for any password. The Administrator
should immediately implement a new password as a matter of prudent security
practice. Once the Administrator¡¦s password is saved, the IT50 Network Camera
will ask for the user¡¦s name and password before each access. The Administrator
can set up a maximum of twenty (20) user accounts. Each user can access the
IT50 Network Camera except to perform system configuration. Some critical
functions are exclusive for the Administrator, such as system configuration,
user administration, and software upgrades. The user name for the Administrator
is permanently assigned as ¡§root¡¨. Once the password is changed, the browser
will display an authentication window to ask for the new password.
Once the password is set, there is no
provision to recover the Administrator¡¦s password. The only option is to restore to the
original factory default settings.
After opening the Web browser and typing in
the URL of the IT50 Network Camera, a dialogue window pops up to request a
username and password. Upon successful authentication, the following figure is
displayed.
The foreground is the login window and the
background shows the message if authentication fails. The user may check the
option box to save the password for future convenience. This option is not available to the
Administrator for obvious reason.
For the initial access to the IT50 Network
Camera in Windows, the web browser may prompt for permission to install a new
plug-in for the IT50 Network Camera. Permission request depends on the Internet
security settings of the user¡¦s PC or notebook. If the highest security level
is set, the computer may prohibit any installation and execution attempt. This
plug-in has been registered for certificate and is used to display the video in
the browser. Users may click on 
to proceed. If the web browser does not
allow the user to continue to install, check the Internet security option and
lower the security levels or contact your IT or networking supervisor for help.
The main page layout has two parts:
Configuration functions: The camera can be configured using these user interfaces.
Camera View:
What the camera sees.
Click on
the configuration link to the left of the image window to enter the
configuration page.
Click
on the magnifier icon under the camera view then the digital zoom control panel
will be shown. Uncheck ¡§Disable digital zoom¡¨ and use the slider control to
change the zoom factors.
Snapshot
Click
on ¡§Snapshot¡¨, web browser will pop up a new window to show the
snapshot. Users can point at the snapshot and click the right button of mouse
to save it.
At
the initial access to the ¡§Connection type¡¨ page in Windows, the web browser
will ask for a new plug-in installation, the plug-in being the IT50 Network
Camera. This plug-in has been registered for certification and can be used to
change the parameters at the client¡¦s site. The user may click on to install the plug-in. If the web
browser does not allow the user to complete the installation, check the
Internet security to lower the security level or contact your IT or networking
supervisor.
There
are two settings for the client side. One is ¡§Media Option¡¨ for users to
determine if audio should be muted. The other is ¡§Protocol Option¡¨ which
allows choices on connection protocol between client and server. There are
three protocols choices to optimize your usage - UDP, TCP and HTTP.
The
UDP protocol allows for more real-time audio and video streams. However,
some packets may be lost due to network burst traffic and images may be
obscured.
The
TCP protocol allows for less packet loss and produces a more accurate
video display. The downside with this protocol is that the real-time effect is
worse than that with the UDP protocol.
The
HTTP protocol must be selected if the network is protected by a firewall
and it only allows HTTP
Port (80) to be opened.
In this mode, audio will not be sent and only video is operational. If no special need is required, UDP
protocol is recommended. Generally speaking, the client¡¦s choice will be in the
order of UDP ¡÷ TCP ¡÷ HTTP. After the IT50 Network Camera is connected successfully,
¡§Protocol Option¡¨ will indicate the selected protocol. The selected protocol
will be recorded in the user's PC and will be used for the next connection. If
the network environment is changed, or the user wants to let the web browser to
detect again, manually select the UDP protocol, save, and return HOME to
re-connect.
<url> http://<IT50Network Camera>/protocol.html
<IT50
Network Camera> is the domain name or the original IP address of the IT50
Network Camera.
Best
performance generally equates to the fastest image refresh rate with the best
video quality, and at the lowest network bandwidth as possible. The three
factors, ¡§Maximum frame rate¡¨, ¡§Fix bit rate¡¨, and ¡§Fix quality¡¨ on the Video
Configuration page, are correlative to allow for achieving the best performance
possible.
For Best
Real-time Video Images
To
achieve good real-time visual effect, the network bandwidth should be large
enough to allow a transmission rate of greater than 20 image frames per second.
If the broadband network is over 1 Mbps, set the ¡§Fix bit rate¡¨ to 1000Kbps or
1200Kbps, and set ¡§Fix quality¡¨ at the highest quality. The maximum frame rate
is 30. If your network bandwidth is more than 384Kbps, you can fix the bit rate
according to your bandwidth and set the maximum frame rate to 30 fps. If the
images vary dramatically in your environment, you may want to slow the maximum
frame rate down to 20 fps in order to lower the rate of data transmission. This
allows for better video quality and the human eyes cannot readily detect the
differences between those of 20, 25, or 30 frames per second. If your network
bandwidth is below 384 Kbps, set the ¡§Fix bit rate¡¨ according to your bandwidth
and try to get the best performance by fine-tuning with the ¡§Maximum frame
rate¡¨. In a slow network, greater frame rate results in blur images. Another
work-around is to choose ¡§Half¡¨ in the ¡§Size¡¨ option for better images, or
¡§Halfx2¡¨ for a larger image view. Video quality performance will vary somewhat
due to the number of users viewing on the network; even when the parameters
have initially been finely tuned.
Performance will also suffer due to poor connectivity because of the
network¡¦s burst constraint.
Only Quality
Images Will Do
To
have the best video quality, you should set ¡§Fix quality¡¨ at ¡§Detailed¡¨ or
¡§Excellent¡¨ and adjust the ¡§Maximum frame rate¡¨ to match your network¡¦s
bandwidth. If your network is slow and you receive ¡§broken¡¨ pictures, go to the
TCP protocol in ¡§Connection type¡¨ and choose a more appropriate mode of
transmission. The images may suffer a time delay due to a slower connection. The delay will also increase with added
number of users.
Somewhere Between
Real-time and Clear Images
If
you have a broadband network, set ¡§Fix quality¡¨ at ¡¨Normal¡¨ or better, rather
than setting ¡§Fix bit rate¡¨. You can also fix the bandwidth according to your
actual network speed and adjust the frame rate. Start from 30 fps down for best results
but not below 15 fps. If the image
qualities are not improved, select a lower bandwidth setting.
Protect the IT50
Network Camera by passwords
The
IT50 Network Camera is shipped without any password by default. That means
everyone can access the IT50 Network Camera including the configuration as long
as the IP address is known. It is necessary to assign a password if the IT50 Network
Camera is intended to be accessed by others. Type a new password twice in (1)
to enable protection. This password is used to identify the administrator. Then
add an account with user name and password for your friends in (2). The IT50
Network Camera can provide twenty accounts for your valuable customers or
friends. Each account identifies the access right rather than the real visitor.
That allows multiple visitors share the same account of different level. An option to access DI/DO is provided
for each account. Some users may need to prohibit from controlling your
attached devices. You may delete some users from (3).
More flexible
options for viewers (4)
The
first option allows anyone uses ¡§demo¡¨ as the user name to view without
password. The Administrator can also decide if more viewers are allowed to
watch the video if the viewers exceed the limit. The overloaded viewers will
have snapshot mode instead.

Demo on multiple
sites ¡V mid-scale service
The
IT50 Network Camera can allow ten visitors on-line simultaneously. After
Installation, focus the IT50 Network Camera on any view you would like friends
to share and tell the visitors to type in the web browser address.
Caution: You may want to maintain
your visitor¡¦s list in the security configuration page to block out unexpected
visitors. No need to have the geeks¡¦ skill and equipments, no need to find
suitable software.
Product demo for
e-business ¡V large-scale service
If
the number of visitors has exceeded the limit, the IT50 Network Camera can
allow the "overload" viewers to see the snapshots in JPEG mode, on
the homepage. These are still
images and will be refreshed periodically and automatically. It needs a script function supported by
the web browser.
1.
Click on ¡§Configuration¡¨ on homepage,
2.
Click on ¡§Security¡¨ at the left column,
3.
Go to the page bottom and check ¡§Allow more viewers with snapshot mode¡¨,
4.
Set the snapshot interval to refresh the still image automatically. The longer
the snapshot interval is, the better the snapshot mode works for more viewers.
If
you want to expand to allow in more viewers, the host server should be able to
handle large network traffic, which must handle the picture refreshing from the
IT50 Network Camera.
If
the web space has FTP service,
Set
the IT50 Network Camera as an FTP client to upload the pictures. The access to
the IT50 Network Camera will be independent of the number of viewers and the
picture quality will remain constant.
1.
Click on ¡§Configuration¡¨ on homepage,
2.
Click on ¡§Network¡¨ at the left column,
3.
Fill the FTP related settings including server, user name and password, as well
as the upload path if specified by the web space,
4.
Click on save and wait for system restart,
5.
Click on ¡§Application¡¨ at the left column,
6.
Select ¡§Sequential operation¡¨ and set the interval,
7.
Select FTP without date time suffix as the upload method and click on save,
8.
The image file uploaded to the web space is named ¡§video.jpg¡¨. Check if the
file is successfully uploaded to the correct folder,
9.
Prepare a homepage with the embedded image reference to the image file uploaded
via FTP in advance.
If
the web space has no FTP service,
An
auto-refresh homepage can be used to periodically poll the newest image from
the IT50 Network Camera. It is most efficient if using a free web space
provider as the FTP service may be limiting.
1.
Prepare an auto-refresh homepage like the following example. The URL of image
is http://¡§IP address of the IT50 Network Camera¡¨/cgi-bin/video.jpg. Modify the
IP address according to your IT50 Network Camera. Define the refresh interval
according to your network bandwidth for best result. If the refresh rate is too
fast and there is a large number of visitors, this may overload the IT50
Network Camera and slows the response.
