D-Link DCS-±1±0 User Manual
Section ³ - Security
To ensure the highest security and prevent unauthorized
use of the Network camera, the Administrator has the
exclusive privilege to access the System Administration
settings to allow users entry and authorize privileges
for all users. The Network camera supports multi-level
password protection/access to the Network 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 Network
camera they will have the right to view the image transmitted by the Network camera.
When the Network 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 Network 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
Network camera. This
procedure should be done as soon as possible since the security features of the Network camera will not be enabled
until the Administrator Password is defined.
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.

Run the DCC program from the CD included with the DCS-2120. Follow the steps in the Quick Installation Guide to
configure the DCS-2120. 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.
1
Assign a Local IP Address to Your Camera
After you have completed the setup of the DCS-2120 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 Network 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.
This is the IP Address assigned to your camera. Write it down for later use. 172.17.5.108 is only an example. You will
probably have a different IP Address.
