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. The
Ethernet cable should meet the specs of UTP Category 5 or
better and not exceed 100 meters in length.
The 9520 Network Camera can be powered with either the 12VDC power supply
(included) or with an 802.3af compliant Power Over Ethernet (PoE) source.
The Network camera can operate in two network modes, DHCP (default) or Fixed IP
address.
Upon powering up, the LED will light up and the device will go through the booting
process. The LED will be steady amber while booting up and acquiring an IP address.
After getting an IP Address and completing the boot process, the LED will blink green
every second to indicate proper operation (heartbeat).
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.

- 5 -
Network Installation
Make sure the network cable is firmly connected to both the camera and the network
switch. After attaching the Ethernet cable, plug in the power adapter. If the LED blinks
green, go to the next paragraph, “Software installation.”
Digital Input/Output
This Network Camera provides a general I/O terminal block with one digital input and one
digital output device control.
Software Installation
Before installing your Network Camera, install the DVTel Device Wizard program
included in the product CD-ROM. Refer to the Wizard manual for installation
requirements.
Use the device Wizard to locate the Network Camera. There may be many Network
Cameras in the local network. Users can differentiate the Network Cameras using the
serial numbers (same as mac address). The serial number is printed on the labels on the
carton and on the back of the Network Camera body. Please refer to the Wizard manual
for details.

- 6 -
Once installation is complete, the Administrator should proceed to the
"Initial Access to the Network Camera" section for necessary checks and
configurations.
Initial Access to the Network Camera
Configure IP address
The Network Camera can be connected either before or immediately after software
installation onto the Local Area Network. If DHCP is not used to assign an IP address,
use the DVTel Device Wizard to assign the fixed IP address and complete the network
settings, 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 by following the steps in the “Troubleshooting” chapter of the
Appendix.
Password Protection to prevent Unauthorized Access
The default Administrator’s password is blank and the Network Camera will not initially
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
A PC with a Windows operating system can use Internet Explorer (IE) to connect to the
Network Camera. A plug-in will be installed into IE when it is connected for the first
time. A PC with a Linux operating system can connect to the camera using a browser
like Firefox. QuickTime must first be installed to view streaming.
Authentication
After opening the Web browser and typing in the URL of the Network Camera, a
dialogue window pops up requesting 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 reasons.

- 8 -
Installing plug-in
For 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 when using Internet
Explorer. 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, which has a registered digital
certificate, 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.

Client settings
There are four settings for the client side in IE. The first option is “Stream Options”
for users to determine which stream is to e viewed. This product supports dual-streams.
The second one is “MPEG-4 Media Options” for users to determine which media is to
be streaming under MPEG-4 mode. The third one is “MPEG-4 Protocol Options”
which provides options on the connection protocol between client and server. There are
four protocol choices to optimize your usage – UDP unicast, UDP multicast, TCP and
HTTP:
The UDP unicast 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 UDP multicast protocol allows the saving of server bandwidth while serving
multiple clients at the same time.
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 allows the same quality as TCP protocol and the user doesn’t need

- 12 -
to open a specific port to stream under some network environments.
If there are no special network requirements, UDP unicast protocol is recommended.
Generally, the client’s choice will be in the order of UDP multicast →UDP unicast →
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 detect again, manually select the UDP protocol,
save, and return HOME to re-connect.
The fourth setting is “Save Options.” Users can specify the recording folder and file
name prefix and suffix here.
Digital output
Click “ON”; the digital output of the Network Camera is triggered. Or, clicking “OFF”
can let the digital output turn into normal state.

- 13 -
Administration
Only the Administrator can access the system configuration. Each category in the left
column will be explained in the following pages. The bold text represents the specific
phrases on the Option pages. The Administrator may type the URL below the figure to
directly enter the frame page of configuration. If the Administrator also wants to set
certain options through the URL, read the reference appendix for details.
<url> http://<Network Camera>/setup/system.html
<Network Camera> is the domain name or original IP address of the Network Camera.
