When the Internet Camera is used for the first time, it is highly
recommended that the Administrator set the
Administrator’s Password
to constrain user access to the Internet Camera since the Default
settings are Null String (no password). Once the Password is defined,
only the Administrator has access to the management of the
Internet
Camera. This procedure should be done as soon as possible since the
security features of the Internet Camera will not be enabled until the
Administrator Password
is defined.
To ensure the highest security and prevent unauthorized use of the Internet
Camera, the
Administrator
has the exclusive privilege to access the
System
Administration
settings to allow users entry and authorize privileges for all
users. The Internet Camera supports multi-level password protection/access
to the Internet Camera that can be restricted to defined users who have a
User
Name
and
User Password,
which is assigned by the Administrator.
The Administrator can release a public user name and password so that when
remote users access the Internet Camera they will have the right to view the
image transmitted by the Internet Camera.
At this point it is highly recommended that you click on the
Configuration
button
on the Home screen, and then the
Tools
tab to bring you to the
Admin
screen.
Enter a
password
for security purposes.

Using & Configuring the DCS-3220
with a NAT Router
D-Link’s
DCS-3220
is a versatile and cost effective Internet Camera offering
both video and audio monitoring. It can also serve as a powerful surveillance
system in security applications. The
DCS-3220
can be used with any wired or
wireless router. This section explains how to view the camera from either the
Internet or from inside your internal network.
Materials Needed:
1
DCS-3220
Internet Camera
1 Ethernet Cable
A Wired or Wireless router such as the D-Link DI-624 Wireless Router
Ethernet based PC for system configuration
SETTING UP THE DCS-3220 FOR USE BEHIND A ROUTER
Installing a
DCS-3220
Internet Camera on your network is an easy 4–step
procedure:
c
Assign a local IP Address to your Internet Camera
d
View the Internet Camera Using Your Internet Explorer Web browser
e
Access the Router with Your Web browser
f
Open Virtual Server Ports for Your Router (Enable Remote Viewing)
This section is designed to walk you through the setup process for installing
your camera behind a router and enable remote video viewing. For the basic
setup of the
DCS-3220
, follow the steps outlined in the
Quick Installation
Guide
.
After you have completed the setup of the
DCS-3220
outlined in the
Quick
Installation Guide
you will have an operating camera that has an assigned IP
Address. Because you are using a router to share the Internet with one or more
PCs, the IP Address assigned to the Internet Camera will be a local IP Address.
This allows viewing within your Local Area Network (LAN) until the router is
configured to allow remote viewing of the camera over the Internet.
Run the Installation Wizard program from the CD included with the
DCS-3220
.
Follow the steps in the
Quick Installation Guide
to configure the
DCS-3220
.
The camera will be assigned a local IP Address that allows it to be recognized
by the router. Write down this IP Address for future reference.

View the Internet Camera using your Internet Explorer Web
browser
Viewing the Video on the browser to test the connection
Click on the
Configuration
button on the left side of the display. The Network
Configuration page displays the ports used by HTTP and Streaming audio
and video.
This is the IP Address
assigned to your camera.
Write it down for later use.
192.168.0.146 is only an
example. You will probably
have a different IP Address.
Run your Internet Explorer Web browser. In the address bar, type in the IP
Address that was assigned to the Internet Camera by the
Installation Wizard
program. The
DCS-3220
Home Page appears with a window displaying live
video from the camera. You are able to view this screen from any PC running
Internet Explorer on your LAN.
Click on the
Configuration
button.

NAT Router (continued)
Router Set-Up and Installation
The following steps generally apply to any router that you have on your network.
The D-Link DI-624 is used as an example to clarify the configuration process.
Configure the initial settings of the DI-624 by following the steps outlined in the
DI-624
Quick Installation Guide
.
e
Access Your Router on Your Web Browser
If you have cable or DSL service, you will most likely have a dynamically
assigned WAN IP Address. ‘Dynamic’ means that your router’s WAN IP address
can change from time to time depending on your ISP. A dynamic WAN IP Address
identifies your router on the public network and allows it to access the Internet.
To find out what your router’s WAN IP Address is, go to the
Status
menu on
your router and locate the WAN information for your router. As shown on the
next page the WAN IP Address will be listed. This will be the address that you
will need to type in your Web browser to view your camera over the Internet.
Ports that are used by the DCS-3220
These are the port settings for
your camera. If necessary, these
ports can be changed if they are
already in use by other devices
(e.g. in a multiple camera environ-
ment).

Note:
Because a dynamic WAN IP can change from time to time depending on
your ISP, you may want to obtain a Static IP address from your ISP. A Static IP
address is a fixed IP address that will not change over time and will be more
convenient for you to use to access your camera from a remote location. The
Static IP Address will also allow you to access your camera attached to your
router over the Internet

Open Virtual Server Ports to Enable Remote Image Viewing
Using & Configuring the DCS-3220 with a
NAT Router (continued)
The firewall security features built into the DI-624 router prevent users from
accessing the video from the
DCS-3220
over the Internet. The router connects
to the Internet over a series of numbered ports. The ports normally used by the
DCS-3220
are blocked from access over the Internet. Therefore, these ports
need to be made accessible over the Internet. This is accomplished using the
Virtual Server
function on the DI-624 router. The Virtual Server ports used by
the camera must be opened through the router for remote access to your
camera. Virtual Server is accessed by clicking on the
Advanced
tab of the
router screen.
Determine Your Router’s IP Address (WAN)
Your WAN IP
Address will be
listed here.
