Installation
Hardware installation
Before installing one or more DDK-3000 Video Encoders at their desired locations, the administrator
should record the serial numbers that can be found on both the unit and on the packing carton.
Cable connection
To install the DDK-3000 Video Encoder, the unit should first be connected to
a network switch via the RJ45 socket. The Ethernet cable should meet UTP
category 5 standards and not exceed 300 feet.
Power on
Make sure all cables are correctly and firmly connected before powering the DDK-3000 Video Encoder.
Turn on cameras, sensors, or any other alarm inputs and then plug in the 12VDC power adaptor of the
DDK-3000 Video Encoder to an AC power socket. When the power adapter is plugged into the utility
socket, the front LED will alternate between green and red for several cycles. After completing the self-
test, the LED will remain green, indicating that the Video Encoder is in standby mode for receiving an IP
address. After getting an IP Address, the LED should blink green every second. Otherwise refer to
Appendix A for troubleshooting.
Installation
In this manual, “User” refers to whoever has access to the DDK-3000 Video Encoder, and
“Administrator” refers to the person who can configure the encoder and grant user access to the device.
Following the hardware installation, users can utilize the Installation Wizard program included in the
product CD-ROM to locate the DDK-3000 Video Encoder on the network. If multiple encoders are
present on the local network, users can differentiate the devices by their serial numbers. The serial number
is printed on the packing carton and also on the DDK-3000 Video Encoder. Please refer to the user’s
manual of the Installation Wizard for detail.
Once installation is complete, the Administrator should proceed to the next section, “Initial Access to the
Video Encoder,” for necessary checks and configurations.
Connect the jack of the power adapter to DDK-3000 Video Encoder prior to plugging the utility end
into the utility power socket. This will reduce accidental electrical surge.
Consult with the dealer of the peripherals for correct installation.

Initial Access to the Video Encoder
Check Network Settings
Once the Installer program has been used to assign an IP address to the DDK-3000 Video Encoder, the
unit can be accessed immediately over the local network. The Administrator should complete the network
settings on the configuration page of the unit, including the correct subnet mask and IP address of
gateway and DNS. Ask your network administrator or Internet service provider for this information.
Unless programmed otherwise, the DDK-3000 Video Encoder requires that the Administrator run the
Installer program each time it reboots. If the network settings are to remain unchanged, this option should
be disabled. Refer to “Network settings” on the System Configuration page for details. If any setting is
entered incorrectly and the unit cannot proceed with system setup, the encoder should be reset to factory
default settings. Follow the steps in the “Troubleshooting” chapter of the Appendix.
Add Password for Authentication
The default Administrator’s password is blank and the DDK-3000 Video Encoder initially will not prompt
the user for a password. Following installation, the Administrator should immediately assign a new
password as a matter of prudent security practice. Once the Administrator’s password is saved, the DDK-
3000 Video Encoder will ask for the user’s name and password before granting access. The Administrator
can set up a maximum of twenty (20) user accounts. Each user can access the DDK-3000 Video Encoder
but only the Administrator’s password will provide access to the system configuration menus. Some
critical functions are exclusive to 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 root password is set, there is no provision for the Administrator to recover it. The only option is
to restore the unit to the factory default settings.

Installing Plug-in
During initial access to the DDK-3000 Video Encoder in Windows, the web browser will normally
prompt for permission to install a pop-up plug-in for the DDK-3000 Video Encoder. The permission
request depends on the Internet security settings of the user’s PC or notebook. If the highest security level
is selected, the computer may prohibit installation of the plug-in. This plug-in has been registered for
security and is required to display the video in the browser. Users should click on to proceed. If
the web browser does not allow the user to continue to install, check the Internet security options and
lower the security levels or contact your networking supervisor for help.

new plug-in installation to support the DDK-3000 Video Encoder. This plug-in has been registered for
certification and is required to change the PC parameters at the client’s site. The user should click
to install the plug-in. If the web browser does not allow the user to complete the installation, check the
Internet security settings to lower the security level or contact the IT or networking supervisor.

- 12 -
There are two options listed on the Client settings page:
• Media Option, which allows users to specify if audio should be muted
• Protocol Option, which lists the available communication protocols that can be established between the
client and the encoder
There are three protocols choices to optimize usage:
• UDP
• TCP
• HTTP
The UDP protocol enables real-time audio and video transmission. However, some packets may be lost
during heavy network traffic bursts, which can impact the video quality.
Selecting the TCP protocol will normally result in less packet loss, thereby producing better video quality.
Choosing this protocol may, however, increase latency resulting in a slight delay in the video transmission
depending upon the network infrastructure.
The HTTP protocol should be selected if the network is protected by a firewall and only allows HTTP
Port (80) to be opened. In this mode, only video is available and audio will not be sent. 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 DDK-
3000 Video Encoder is successfully connected, “Protocol Option” will indicate the selected protocol. The
selected protocol will be saved to the user’s PC and will automatically be established during the next
connection. If the network environment changes, or the user wants to manually change the transmission
protocol, simply open the Client settings page, select the desired option, save, and return HOME to re-
connect.
<url> http://<DDK-3000 Video Encoder>/protocol.html
<DDK-3000 Video Encoder> is the domain name or the original IP address of the DDK-3000 Video
Encoder.

Fine-tuning for Optimum Performance
Optimum performance of the DDK-3000 Video Encoder generally equates to having a high frame rate,
high-resolution video image at the lowest possible network bandwidth. The three factors, “Maximum
frame rate,” “Fix bit rate,” and “Fix quality,” on the Video Configuration page, should be adjusted to
achieve the best possible performance based on the available bandwidth.
For Best Real-time Video Images
To achieve optimum real-time video, the available network bandwidth should be capable of transmitting a
minimum of 20 image frames per second. If a broadband network is available, transmission rates will
normally exceed 1 Mbps. In this environment, set the “Fix bit rate” to 1000Kbps or 1200Kbps, and set
“Fix quality” at the highest quality. The maximum frame rate is 25 fps in a PAL system and 30 fps in an
NTSC system.
For instance, if network bandwidth is limited to 384 Kbps, you can fix the bit rate at a lower setting and
set the maximum frame rate to 25 fps or 30 fps. If the video images are inconsistent, you may want to
slow the maximum frame rate down to 20 fps in order to lower the rate of data transmission. This will
produce better video quality. 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 the “Maximum frame
rate.”
On a slow network, choosing a higher frame rate will decrease the video quality. It is therefore important
to test a combination of settings to achieve the best overall video quality. Another way to improve the
video image quality is to select “Half” in the “Size” option, which will reduce the screen size. Video
quality will also be impacted by the number of users simultaneously connected to the encoder, even when
the parameters have initially been finely tuned.

- 14 -
Optimum Quality Images
To achieve the best video quality, the “Fix quality” setting should be “Detailed” or “Excellent,” and the
“Maximum frame rate” should match your network’s bandwidth. If your network is slow and you
encounter distortion in the video images, go to the TCP protocol in “Connection type” and choose a
different mode of transmission. This may increase the amount of latency in the video, although the quality
should improve.
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. It is
recommended that you start at 30 fps and adjust downward for best results, but not below 15 fps. If the
image quality does not improve, select a lower bandwidth setting. Once again, it is important to test a
variety of settings in order to identify the combination that works best in your particular network
environment.
Establishing accounts for new users
Protecting DDK-3000 Video Encoder with passwords
By default, the DDK-3000 Video Encoder is shipped without a password. That means anyone can access
the DDK-3000 Video Encoder and its configuration settings, as long as the IP address is known. It is
necessary for the administrator to assign a password if others will have access to the DDK-3000 Video
Encoder. This will allow multiple users to view the video without having access to the configuration
menu. The administrator should enter a root password and confirm it in section 1 above. This password is
used to identify the administrator. Up to 20 additional users (without administrator rights) can then be
added in section 2. An option to access DI/DO (digital input/output) is also provided for each account,
allowing the administrator to prohibit certain users from controlling any devices attached to the encoder.
Users can be deleted from section 3.

- 15 -
More flexible options for viewers
As indicated in section 4 above, options are available to accommodate additional users. Selecting the first
option will allow anyone using “demo” as the user name to connect without a password. The
Administrator can also decide if additional users should be allowed to access the video when the number
of simultaneous users exceeds the limit. If this option is enabled, the users who are creating the overload
will have access only to snapshot images rather than motion video.

The DDK-3000 Video Encoder can support up to 10 users simultaneously. After installation, any camera
attached to the DDK-3000 Video Encoder can be viewed simply by entering the IP address of the encoder
in the web browser.
Product demo for e-business – large-scale service
If the number of users exceeds the limit, the DDK-3000 Video Encoder can allow the “overload” viewers
to see the snapshots in JPEG mode, on the homepage. These are still images and will be periodically
refreshed automatically. It needs a script function supported by the web browser.
1. Click “Configuration” on homepage.
2. Click “Security” in 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.
To increase substantially the number of simultaneous viewers, a host server, capable of handling a large
volume of network traffic, can be configured on the network to receive and refresh incoming images from
the DDK-3000 Video Encoder. The host should be set up as an FTP server with the DDK-3000 Video
