Installation
In this manual, "User" refers to whoever has access to the Network Camera, and
"Administrator" refers to the person who can configure the Network Camera and grant
user access to the camera.
Hardware installation
Please verify that your product package contains all the
accessories listed in the foregoing Package Contents.
Depending on the user’s application, an Ethernet cable
may be needed. The Ethernet cable should meet the specs
of UTP Category 5 and not exceed 100 meters in length.
Connect the power adapter jack to the Network
Camera before plugging in to the power socket. This will
reduce the risk of accidental electric shock.
Upon powering up, the device runs through a self-test procedure and the front LEDs will
blink between green and red a few times. If self-test passes, the LED will be green and
the Network Camera will standby for getting IP address. After getting IP Address, the LED
will blink green every second. If self-test fails the red LED will blink several times. Refer
to Appendix A for troubleshooting.
Software installation
At the end of the hardware installation, users can use Installation Wizard program
included in the product CDROM to find the location of the Network Camera. There may be
many Network Cameras in the local network. Users can differentiate the Network
Cameras with the serial number. The serial number is printed on the labels on the carton
and the back of the Network Camera body. Please refer to the user’s manual of
Installation Wizard for detail.

Once installation is complete, the Administrator should proceed to the next
section "Initial access to the Network Camera" for necessary checks and
configurations.
Initial Access to the Network Camera
Check Network Settings
The 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 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 Network Camera, restore the factory settings following the
steps in the “Troubleshooting” chapter of the Appendix.
Add Password to prevent Unauthorized Access
The default Administrator’s password is blank and the 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 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 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.

How to Use
Authentication
After opening the Web browser and typing in the URL of the 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.

Installing plug-in
For the initial access to the Network Camera in Windows, the web browser may prompt
for permission to install a new plug-in for the 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.

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
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.

Administrator’s capability
Fine-tuning for Best Performance
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
- 14 -
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.
