Section 1 - Product Overview
Introduction
The D-Link SECURICAM Network DCS-2120 Wireless Network camera is a powerful surveillance system that connects
wirelessly to your 802.11b/g network. The DCS-2120 features enhanced 802.11b/g and connects wirelessly at a rate
of up to 54Mbps1(Megabits per second). The DCS-2120 differs from a conventional PC Camera because it is a
standalone system with a built-in CPU and Web server, providing a low-cost solution capable of solving demanding
security and home/ofce monitoring needs. Snapshot enables you to save images directly from a Web browser to a
local hard drive without installing any additional software. With 0.5 lux light sensitivity, the DCS-2120 is capable of
capturing video in rooms with minimal lighting. You can also zoom in with the DCS-2120’s 4x digital zoom2feature.
The DCS-2120 gives you the ability to monitor video and audio in your home/ofce using an Internet browser from any
where in the world! Simple installation procedures, along with the built-in Web-based interface offers easy integration
to your network environments.
Customers also have the ability to view live video streams from a compatible 3G cell phone. The live camera feed of
the D-Link Wireless Network camera can be pulled from the 3G cellular network by using a compatible cell phone with
a 3G video player3. From anywhere within the 3G service area, both consumers and small businesses are offered a
exible and convenient way to remotely monitor a home or ofce in real time.
Note: Use of audio or video equipment for recording the image or voice of a person without their knowledge and consent
is prohibited in certain states or jurisdictions. Nothing herein represents a warranty or representation that the D-Link
product provided herein is suitable for the end-user’s intended use under the applicable laws of his or her state. D-Link
disclaims any liability whatsoever for any end-user use of the D-Link product, which fails to comply with applicable
state, local, or federal laws.
1 Maximum wireless signal rate derived from IEEE Standard 802.11g specications. Actual data throughput will vary. Network conditions and environmental factors
lower actual data throughput rate.
2 4x digital zoom enlarges an image by magnifying the pixels in a selected portion of the image by 4 times.
3 3G phone must be equipped with 3G video playback such as RealPlayer®or PacketVideo for Symbian or PocketPC.

to modify the Network camera settings from a remote site via the Intranet or the Internet. Administrators are
capable of monitoring live video feeds as well as recording video and taking snapshots.
• Broad Range of Applications: With today’s high-speed Internet, the Network camera provides the ideal solution
for live video images over the Intranet and Internet for remote monitoring. The DCS-2120 allows remote access
from an Internet Explorer Web browser for live image viewing with audio and allows the administrator to manage
and control the Network camera anywhere and any time. Apply the Network camera to monitor various objects
and places such as homes, ofces, banks, hospitals, child-care centers, amusement parks and other varieties of
industrial and public monitoring. The Network camera can also be used for intruder detection with its motion-detection
mode, capture still images and video images for archiving and many more applications. The wireless capability

Power LED
The power LED is positioned in the center of
the camera below the Network camera Lens.
As soon as the power adapter is connected
to the camera, the power LED will ash red
and blue several times, indicating that the
DCS-2120 is conducting a self-test. Upon
passing the self-test, the LED will turn blue,
indicating a good connection to an Ethernet
or wireless connection. A red LED indicates
that no connection has been made.

Wireless Installation Considerations
The D-Link wireless network camera lets you access your network using a wireless connection from virtually anywhere
within the operating range of your wireless network. Keep in mind, however, that the number, thickness and location of
walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary
depending on the types of materials and background RF (radio frequency) noise in your home or business. The key
to maximizing wireless range is to follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link adapter and other network devices to a
minimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position
your devices so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a
45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet
(14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead
of at an angle) for better reception.
3. Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on
range. Try to position access points, wireless routers, and computers so that the signal passes through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water
(sh tanks), mirrors, le cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that
generate RF noise.
5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and
home security systems), your wireless connection may degrade dramatically or drop completely. Make
sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits
a signal even if the phone in not in use.

*A DHCP server is a device that supplies IP Addresses to its
clients that are on the same network.
Configuration
Turn on the computer and Insert the D-Link DCS-2120 Driver CD in the CD-ROM drive. The step-by-step instructions
will help you to search and setup your IP camera smoothly and quickly.
If the CD Autorun function does not automatically start on your computer, click Windows®Start > Run. In the Run
command box type “D:\DCS5220.exe”, where D: represents the drive letter of your CD-ROM. If it does start, proceed

UPnP (Universal Plug and Play) is a networking architecture that provides
compatibility among networking equipment, software, and peripherals. The
DCS-2120 is an UPnP enabled Network camera. If your operating system is
UPnP enabled, the device will be easier to congure. If you do not want to use
the UPnP functionality, it can be disabled by unchecking the Enabled UPnP
checkbox in the Advanced > Network page (see page 32). Use the following
steps to enable UPnP settings only if you are running Windows®XP. If you are
running Windows®98/2000, UPnP is not available.
Go to Start > Settings. Click Control Panel.
