Section 1 - Product Overview
• 3G Compatibility: Offers customers the ability to view live video streams from a compatible 3G cell phone. The
live camera feed can be pulled from a 3G cellular network by using a compatible cell phone with a 3G video
player.
• Supports a Variety of Platforms: Supporting TCP/IP networking, SMTP e-mail, HTTP and other Internet related
protocols, the DCS-2120 Network camera can be integrated into other Internet/Intranet applications because
of its standards-based features.
• Remote Snapshot Images: You can save snapshots directly from the Web browser to a local hard drive
without installing any additional software, making it convenient to instantly capture any moment from a remote
location.
• Low Light Recording and 4x Digital Zoom: The DCS-2120’s 0.5 lux light sensitivity allows you to capture video
in rooms with minimal lighting, making it ideal for use at night time. The camera also features 4x digital zoom
for closer viewing.
• Web Configuration: Using the Internet Explorer Web browser, administrators can configure and manage the
Network camera directly from its own Web page via the Intranet or the Internet. Up to 20 user names and
passwords are permitted, with privilege settings controlled by the administrator.
• Powerful Surveillance and Remote Monitoring Utility: The powerful IP surveillance software allows an administrator
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, offices, 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

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 flash 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

Hardware Installation
Connect an Ethernet cable to the Ethernet connector located on the Network
camera’s bottom panel and attach it to the network.
Note:
It is required that an Ethernet cable is used during initial setup. Once your
wireless configuration is set, you may disconnect the Ethernet cable.
Attach the external power supply to the DC power input connector located on the
Network camera’s bottom panel (labeled 5VDC) and connect it to your wall outlet.
When you have a proper connection, the LED will light up.
The LED will flash red and blue when you first power on the unit. The LED will not
turn blue until the camera has received a network IP address.

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
(fish tanks), mirrors, file 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.
