Wireless Installation Considerations
The D-Link wireless internet 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.

rate. The frame rate is used with the
Video quality control setting (below)
to optimize bandwidth utilization and
video quality.
Key frame interval:
Determines how many repeated P frames will appear after one I frame. Large “Key frame interval” can reduce
the bit rate, but cause image to be corrupted longer if there is packet loss while transmitting. The video quality
may be poor due to the sending of maximum frame rate within the limited bandwidth when images are moving
rapidly. Consequently, to ensure detailed video quality (quantization rate) regardless of the network, it will utilize
more bandwidth to send the maximal frames when images change drastically.To fix the bandwidth utilization
regardless of the video quality, choose Fix bit rate and select the desired bandwidth. The video quality may be

reduced in order to send maximum frames with limited bandwidth, especially when images change drastically.
For higher video detail regardless of the bandwidth selection, select Fixed quality and select a video quality level.
This setting will utilize more bandwidth to send the maximum frames when images change drastically.
Video quality control: These settings are to optimize your camera performance with your available bandwidth.
Fix bit rate: Select a fixed bandwidth for your camera operation. This option allows the user to select a custom frame rate
suitable for the bandwidth and the storage space.
Fix quality : Selecting fixed quality will roughly select your image quality and will not be as accurate as setting by bit rate.
This setting is easier to use when image quality does not have to be precise. Below is a typical file size after 1
minute of recording at 30fps (frames per second). This is only an average measurement; your file size may differ

Flip: Vertically rotate the video.
Mirror: Horizontally rotate the video. Check both flip and mirror if the DCS-2120 is to be installed upside down.
White Balance: White Balance is related to the color temperature. Color temperature is a way of measuring the quality of a
light source. It is based on the ratio of the amount of blue light to the amount of red light, and the green light is
ignored. The unit for measuring this ratio is in degree Kelvin (K). A light with higher color temperature (i.e., larger
Kelvin value) has “more” blue lights than a light with lower color temperature. The default setting for the camera
is “Auto”.
Time stamp on video: Select this option to display the current date and time on the video image. All the snapshots and video data will

GSM-AMR: A standard adapted audio codec by the 3G video(3rd Generation Partnership Project). It is an Adaptive Multi
Rate-Narrow Band (AMR-NB) speech codec. Select higher bit rate number for better audio quality.

Section 3 - Configuration
Recommendations for Setting Video for the Best Performance:
“Best performance” means the image refresh rate should be the fastest possible and the video quality should be the
best possible at the lowest network bandwidth possible. Three factors, Maximum frame rate, Fix bit rate, and Fix quality
in the Video Configuration page, are related to performance.
Recording settings for real-time motion images
To achieve a real-time visual effect, the network bandwidth should be large enough to transmit 20 image frames
per second (fps) or more. If you are on a broadband network over 1 Mbps, you can set Fix bit Rate to 1000Kbps or
1200Kbps, or set Fix quality to achieve the maximum frames. The maximum frame rate is 25 in 50Hz system and 30 in
60Hz system. If your network bandwidth is more than 384Kbps, you can adjust Fix bit rate according to your bandwidth
and set the maximum frame rate of 25 to 30.
If the images vary dramatically in your environment, you may slow down the maximum frame rate to 20 to decrease the
transmitted data for better video quality. Since the human eye could not easily differentiate between 20 and 25 or 30
frames per second, the slower frame rate will not be noticed. If your network bandwidth is below 384 Kbps, you should
adjust the bit rate according to your bandwidth and experiment to allow for the best frame rate that can be achieved.
The faster frame rate in a slow network will blur the images. You may also try to choose 320x240 in size option for better
images or 640x480 for larger image size. Because the network has burst constraints and everyone’s environment is
not the same, any poor connection will impair normal performance.
Recording settings for clear identification for each image
To have the best video quality, you should set Fix quality to detailed or excellent and tune the Maximum frame rate to
suit your network bandwidth. If you get some broken pictures in a slow network, you can set TCP protocol in Connection
type for a more accurate transmission but the received images may have a lag. Note that any slow connection with
multiple users will impair performance.
Recording settings to compromise between real-time and clear images
If you have a broadband network, set Fix quality to Good image quality, or higher, instead of setting the Bit rate.
Otherwise, fix the bit rate according to your actual network speed and set the frame rate to 30. If the image quality is
low, select a lower frame rate above 15. If the image quality is still not improved, select a lower bit rate.

Video Channel Selection Area: The video channel selection area provides the IP addresses and location information of the connected
video channels for the user’s reference. You can select a video channel in this area and create a schedule
for it.
Primary Schedule: The Primary schedule consists of the day time-line, week time-line, begin time selector, end time selector,
and event mode settings.
Secondary Schedule: The Secondary schedule consists of event mode settings.
Operation Buttons: The operation buttons allow the user to manipulate the edited schedule of the selected video channel.
The scheduler can be closed from here.
The Functionalities of Configuration Components
The four main parts of the scheduler have been briefly described above. The four parts will be described in detail in
the following section.
Video Channel Selection Area
In this area you will select the video channel that you want to set a schedule for. Each video channel will display a name,
an IP address, and the location. Please note that when you switch between video channels in this area, the changes
in the schedule of the previous video channel will be saved automatically.

Primary Schedule
Schedule with Time Lines
There are two different time-lines: hour unit time-line and week unit time-line. You can make your own schedule by
plotting markers in all time-lines. These two time lines are associated with each other. That is, if you make changes in
one time-line, the corresponding changes will be applied with scale to the other three time-lines in the same schedule.
Before you begin, make sure that you select “Once” (page 83) if you want to choose the days to record on.
Week Time-Line
In the figure below, Week time-line is displayed. It includes the time-line, schedule information, and the selected day
in the week.
Marking/Unmarking the Recording Time on the Week Time-Line
The corresponding changes for the markers on the week time-line will be automatically added to the hour time-lines,
which is shown above. You can also mark and unmark the plotted bar by clicking and dragging with the left and the
right mouse button.

Using the Monitor Program
This section depicts, in detail, how to manipulate the monitor tool.
Connection of the DCS-2120
Once you have the privilege to connect to the DCS-2120, the cameras will automatically appear in the video area in
the order they are connected. Once you have set up the camera in the video channel, the color of the channel number
will turn green, indicating that the camera has been added to IP surveillance. If you do not set up the camera for the
video channel, the color of the channel number will be gray.
There is a unique light signal associated with each channel number. It indicates the status of the dedicated video
channel, which is depicted as follows:
Off: The video channel is not connected with any DCS-2120 yet.
Green: The green light means the DCS-2120 associated with this channel number is connected, and the video is monitored
in the video area.
Red: The red light indicates the video from this channel is recording into the video database. In this mode, you don’t have
to drag and drop the channel to the video area. This means that this application software supports real-time recording
with and without real-time monitoring for the dedicated video channel.
Blink: With the motion detection mechanism set in the DCS-2120, the light of the corresponding channel
will blink once the motion event is triggered.
If you do not want to monitor one video, you can drag and drop the video (in the video area) to the
trashcan in the common control area of the monitor program. The following section will demonstrate
the procedures for “drag and drop” step-by-step.

Show the video of a specified channel
This section depicts the method of how to show the video of a specific channel in a display window.
Step 1: Move the mouse cursor to the camera you would like display in the window.
Step 2: Press and hold the left mouse button, and then drag it
to a display window in the video area on the right side of the
screen. Note that the cursor will change according to the area
in order to indicate whether the area is droppable or not.
Step 3: Release the left mouse button while on top of a display
window. The video will appear in the display window as shown
below. In each display layout, only one window can be assigned
to a camera. Also, each camera must have its own separate
window when displayed. Once the video is in a display window,
it can be dragged and dropped to other windows. If you drag
one camera’s video to a window that already has its own
camera’s video, the two cameras will trade display windows.
Dragging and dropping is a very convenient way to manipulate
the video channels in the IP surveillance Software.

of the DO (Digital Output). With these features, you can monitor the remote sensor input from DI and also trigger the
camera by DO switch.
When the color of a DI/DO channel number is gray, that means the video channel has not yet
been connected to a camera.
Alert Message
If you have checked the box “Enable Motion Detect” or “Enable Digital Input” on the Camera
Configurations > Alert Settings screen, the alert message will show in the window shown
above. Once the alert, caused by motion detection or a digital input level change is triggered,
the alert message will be shown in this window. If there are more events than this window
can display, a scroll bar will appear.
The message format is described as follows:
“time”=>”alert type” #”channel number”(“win1”,”win2”,”win3”)
For example, the message “PM 02:41:00=>MO #1(0,1,1)” means that this is a motion
detection alert occurring at 02:41:00 PM in Motion Window 2 and Motion Window 3, for camera #1. If the message “PM
02:41:56=>DI #1” is listed, that means there is an alert triggered by the DI, for camera #1, at 02:41:56 PM .

The items in the settings windows are:
Database Location: The most important item in the settings dialog is the database location setting. You must
set it to the directory that contains the surveillance database to make the program work
properly.
AVI File Location: This sets the directory where exported AVI files will be stored. Exported AVI files will be
stored in the sub-directory (camera name) under the directory you set here.
Snapshot File Location: This sets the directory where bitmap files will be stored when you use the snapshot to
export them. Exporting bitmap files will be stored in the sub-directory (camera name)
under the directory you set here.
Modulation Mode: The modulation mode cannot be changed. This depends on how you recorded the video
sequence in the monitor program. If you select the wrong mode, the video shown in the
display area will become distorted. If you have chosen the wrong modulation mode, you
may open the settings dialog again, change to the correct mode, and restart the playback
program. The display will now be normal.
Normal (Single Frame) Mode
While in the normal (single frame) display mode, you can change the video currently displayed by:
1) Changing the database path for retrieving another one in the settings dialog of “System Control” tool.
2) Changing the location selector to another location in control area.
3) Changing the playback method selector to “Full Range.”
4) Changing the playback method selector to “Time Period.”

Histogram Area
The histogram area in the normal display (single frame) mode only shows the events’ occurred time and the percentage
of motion detection with red bars. If you want to access the histogram area, you must change the area selection indicator
to the histogram area. You can mark one time interval you want to see with a color-inverted region by dragging your
mouse with the left button pressed (as shown below). When you release the left button, the color-inverted region will be
enlarged to the whole histogram area. This color-inverted region will be the new period the program is going to display.
If you change your mind and don’t want to see that period, you can cancel it by just pressing the right button of your
mouse with the left button still pressed. If you click on the left button without dragging it, the action will be the same as
clicking on the pull bar in the same x-axis position. That means the playback system will shift to the pointed time and
show video on the displaying frame. Besides, the dark regions in the histogram area mean there is no existing video
data in that interval. If you click on those regions, nothing will happen except a warning message will pop up.
Using Tools
In this section, the method of how to use the tools in the control panel (shown in the main playback window) will be
discussed.
Selector Tools

Section 3 - Configuration
Location Selector
The location selector is a control that lets you select the camera you want to see (refer to the figure above). The location
name is the same as the camera name (text on video) unless you have specified otherwise.
Period Selector
Period selector provides you a precise way to choose the start time and the end time of a new period. The end time
must be later than the start time. After you provide the correct start and end time, clicking on the “Play” button in the
jog dial will play the new period in the display area with changing the period start and end time label. Besides, the pull
bar and histogram area will change, too. If the selected period is not present in the database, the data in the period
selector will change to the previous correct start and end time, and a warning message will be displayed.
Playback Method Selector
Since the program will record the previous start and end time in “Time Period” and “Events Preview” mode, whenever
you want to change the period selector to see the other periods, you must change the playback method selector to
the mode you want to use first. Otherwise, the period selector will revert back to the previous period set the last time
you changed the playback method selector.
Full Range: If you select this method, the database will be displayed from the beginning to the end of this location.
Any change in the period selector will have no effect except when you change this selector to “Time
Period.”
Time Period: If you change the playback method to “Time Period”, you can modify the start and end time in the period
selector. When you click on the “Play” button in the jog dial, the period you selected will be displayed.
Alert Area Selector
In the preview mode, the playback program can show the information of total events of only one alert window each time.

Section 4 - Security
Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The DCS-2120
offers the following types of security:
• WPA-PSK (Pre-Shared Key)
• WEP (Wired Equivalent Privacy)
What is WEP?
WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption
algorithm. WEP provides security by encrypting data over your wireless network so that it is protected as it is transmitted
from one wireless device to another.
To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using
WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption
requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using
characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange – alphanumeric characters) format.
ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX
for use over the network. Four keys can be defined so that you can change keys easily.
D-Link DCS-2120 User Manual
114
Section 4 - Security
What is WPA?
WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired
Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys
using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t been
tampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard instead of TKIP.
• User authentication, which is generally missing in WEP, through the extensible authentication protocol
(EAP). WEP regulates access to a wireless network based on a computer’s hardware-specific MAC
address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key
encryption system to ensure that only authorized network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric
password between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must
be the exact same key entered on your wireless router or access point.

Section 4 - Security
Setting Security
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.
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.
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.

D-Link DCS-2120 User Manual
117
Section 4 - Security
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 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.
1
Assign a Local IP Address to Your Camera
Run the Installation Wizard 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.
This is the IP Address assigned to your camera. Write it down for later use. 192.168.0.120 is only an example. You will
probably have a different IP Address.

Access the Router with Your Web Browser
If you have cable or DSL Internet 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.
Your WAN IP Address will be listed on the router’s
Status > Device Info page.
D-Link DCS-2120 User Manual
121
Section 4 - Security
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.
4
Open Virtual Server Ports to Enable Remote Image Viewing
The firewall security features built into the DI-624 router prevent users from accessing the video from the DCS-2120
over the Internet. The router connects to the Internet over a series of numbered ports. The ports normally used by the
DCS-2120 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.
Follow these steps to configure your router’s Virtual Server settings:
1 Click Enabled.
2 Enter a different name for each entry.
3 Enter your camera’s local IP Address (e.g., 192.168.0.120 in the example in step 2 on page 120) in the
Private IP field.
4 Select TCP for HTTP port and both (TCP and UDP) for RTSP port.
5 If you are using the default camera port settings, enter 80 into the Public and Private Port section, click Apply.
6 Scheduling should be set to Always so that the camera images can be accessed at any time.

Section 4 - Security
Repeat the above steps adding the port 554 to both the Public and Private Port sections. A check mark appearing
before the entry name will indicate that the ports are enabled.
Important: Some ISPs block access to port 80 and other commonly used Internet ports to conserve bandwidth. Check
with your ISP so that you can open the appropriate ports accordingly. If your ISP does not pass traffic on port 80, you
will need to change the port the camera uses from 80 to something else, such as 800. Not all routers are the same, so
refer to your user manual for specific instructions on how to open ports.
Enter valid ports in the Virtual Server section of your router. Please make sure to check the box next to the camera

from a conventional PC Camera, the Internet Camera is an all-in-one system with built-in CPU and Web-based
solutions providing a low cost solution that can transmit high quality video images for monitoring. The Internet
Camera can be managed remotely, accessed and controlled from any PC/Notebook over an Intranet or the Internet
from a Web browser.
2. What is the maximum number of users that can be allowed to access DCS-2120 simultaneously?
The maximum number of users that can log onto the Internet Camera at the same time is 10. Please keep in mind
the overall performance of the transmission speed will slow down when many users are logged on.
3. What algorithm is used to compress the digital image?
The Internet Camera utilizes MPEG-4 Short Header Mode image compression technology to provide high quality
images.
4. Can I capture still images from the Internet Camera?
Yes you are able to capture still images with the snapshot function from the software application CD supplied with
the Internet Camera or with the snapshot function on the Home page using an Internet browser.
5. Can the Internet Camera be used outdoors?
The Internet Camera is not weatherproof, and needs to be equipped with a weatherproof case in order to be used
outdoors (recommended).
6. When physically connecting the Internet Camera to a network what network cabling is required?
The Internet Camera uses Category 5 UTP cable allowing 10 Base-T and 100 Base-T networking.
7. Can the Internet Camera be setup as a PC-cam on a computer?
No, the DCS-2120 Internet Camera is used only on a wireless 802.11b/g, Ethernet, or Fast Ethernet network.
D-Link DCS-2120 User Manual
133
Section 5 - Troubleshooting
8. Can the DCS-2120 be connected to the network if it consists of only private IP addresses?
Yes, the Internet Camera can be connected to a LAN with private IP addresses.
9. Can the DCS-2120 be installed and work if a firewall exists on the network?
If a firewall exists on the network, port 80 needs to be opened for ordinary data communication. The DCS-2120
uses HTTP port and RTSP port to stream video data. These ports (or the ports you specify from the Advanced Tab
in the Configuration screen if you change the default ports) need to be opened in the firewall device. Please refer to
page 122 for more information.
10. Why am I unable to access the DCS-2120 from a Web browser?
If a router or firewall is used on the network, the correct ports for the DCS-2120 may not be configured on the router
or firewall. To correct the problem, you need to determine if the DCS-2120 is behind a router or firewall and if the
router or firewall is properly configured for the ports the DCS-2120 is using. Refer to page 122 for help in opening
the correct ports on a router or firewall for use with the DCS-2120.
Other possible problems might be due to the network cable. Try replacing your network cable. Test the network
interface of the product by connecting a local computer to the unit, utilizing a Ethernet crossover cable. If the
problem is not solved the Internet Camera might be faulty.
11. Why does the Internet Camera work locally but not externally?
This might be caused by network firewall protection. The firewall may need to have some settings changed in order
for the Internet Camera to be accessible outside your local LAN. Check with the Network Administrator for your
network.
Make sure that the Internet Camera isn’t conflicting with any Web server you may have running on your network.
The default router setting might be a possible reason. Check that the configuration of the router settings allow the
Internet Camera to be accessed outside your local LAN. Please refer to page 122 for more information.

12. I connected the Internet Camera directly to a computer with a cross-over cable Ethernet cable and
received the following Windows error upon running the Installation Wizard:
This Windows error will occur if the Internet Camera is connected to a computer that is not
properly configured with a valid IP address. Turn off DHCP from the Network Settings in Windows®
and configure the computer with a valid IP address, or connect the camera to a router with DHCP
enabled (see page 142).
13. Why does a series of broad vertical white lines appear throughout the image?
It could be that the CMOS sensor has become overloaded when it has been exposed to bright lights such as direct
exposure to sunlight or halogen lights. Reposition the Internet Camera into a more shaded area immediately as
prolonged exposure to bright lights will damage the CMOS sensor.
14. Noisy images occur. How can I solve the problem?
The video images might be noisy if the Internet Camera is used in a very low light environment. To solve this issue
you need more lighting.
15. The images appear to be of poor quality, how can I improve the image quality?
Make sure that your computer’s display properties are set above 256 colors. Using 16 or 256 colors on your
computer will produce dithering artifacts in the image, making the image appear to be of poor quality.
The configuration on the Internet Camera image display is incorrect. Through the Advanced > Image Setting
section of the Web management you need to adjust the image related parameters such as brightness, contrast,
hue and power line frequency for fluorescent light. Please refer to the Advanced > Image Setting section on Page
43 for detailed information.

D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless
connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard,
the D-Link wireless family of products will allow you to securely access the data you want, when and where you want
it. You will be able to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals
instead of wires. Wireless LANs are used increasingly in both home and office environments, and public areas such
as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and
communicate more efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven
to be beneficial for many users.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in
order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Router is a device
used to provide this link.

What is Wireless?
Wireless or WiFi technology is another way of connecting your computer to the network without using wires. WiFi uses
radio frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or office
network.
Why D-Link Wireless?
D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products.
D-Link delivers the performance you need at a price you can afford. D-Link has all the products you need to build your
network.
How does wireless work?
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point
B. But wireless technology has restrictions as to how you can access the network. You must be within the wireless
network range area to be able to connect your computer. There are two different types of wireless networks Wireless
Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).
Wireless Local Area Network (WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access
point has a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an
indoor access point as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal
can reach out up to 30 miles to serve places like manufacturing plants, industrial locations, college and high school
campuses, airports, golf courses, and many other outdoor venues.

Wireless network is easy to setup, but if you’re installing it for the first time it could be quite a task not knowing where to
start. That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless
network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your router or Access Point
Make sure you place the router/access point in a centralized location within your network for the best performance. Try
to place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home.
If you have a two-story home, you may need a repeater to boost the signal to extend the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as away as possible from the router/
access point. This would significantly reduce any interfere that the appliances might cause since they operate on same
frequency.
Security
Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning
on the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.

Warranty
Subject to the terms and conditions set forth herein, D-Link Systems, Inc. (“D-Link”) provides this Limited Warranty:
• Only to the person or entity that originally purchased the product from D-Link or its authorized reseller or distributor, and
• Only for products purchased and delivered within the fifty states of the United States, the District of Columbia, U.S. Possessions or Protectorates, U.S. Military Installations, or addresses with an APO or FPO.
Limited Warranty:
D-Link warrants that the hardware portion of the D-Link product described below (“Hardware”) will be free from material defects in
workmanship and materials under normal use from the date of original retail purchase of the product, for the period set forth below
(“Warranty Period”), except as otherwise stated herein.
• Hardware (excluding power supplies and fans): One (1) year
• Power supplies and fans: One (1) year
• Spare parts and spare kits: Ninety (90) days
The customer’s sole and exclusive remedy and the entire liability of D-Link and its suppliers under this Limited Warranty will be, at D-Link’s
option, to repair or replace the defective Hardware during the Warranty Period at no charge to the original owner or to refund the actual
purchase price paid. Any repair or replacement will be rendered by D-Link at an Authorized D-Link Service Office. The replacement
hardware need not be new or have an identical make, model or part. D-Link may, at its option, replace the defective Hardware or any part
thereof with any reconditioned product that D-Link reasonably determines is substantially equivalent (or superior) in all material respects
to the defective Hardware. Repaired or replacement hardware will be warranted for the remainder of the original Warranty Period or ninety
(90) days, whichever is longer, and is subject to the same limitations and exclusions. If a material defect is incapable of correction, or if
D-Link determines that it is not practical to repair or replace the defective Hardware, the actual price paid by the original purchaser for the
defective Hardware will be refunded by D-Link upon return to D-Link of the defective Hardware. All Hardware or part thereof that is replaced
by D-Link, or for which the purchase price is refunded, shall become the property of D-Link upon replacement or refund.

Appendix E - Warranty
Limited Software Warranty:
D-Link warrants that the software portion of the product (“Software”) will substantially conform to D-Link’s then current functional specifications
for the Software, as set forth in the applicable documentation, from the date of original retail purchase of the Software for a period of ninety
(90) days (“Software Warranty Period”), provided that the Software is properly installed on approved hardware and operated as contemplated
in its documentation. D-Link further warrants that, during the Software Warranty Period, the magnetic media on which D-Link delivers the
Software will be free of physical defects. The customer’s sole and exclusive remedy and the entire liability of D-Link and its suppliers under
this Limited Warranty will be, at D-Link’s option, to replace the non-conforming Software (or defective media) with software that substantially
conforms to D-Link’s functional specifications for the Software or to refund the portion of the actual purchase price paid that is attributable
to the Software. Except as otherwise agreed by DLink in writing, the replacement Software is provided only to the original licensee, and
is subject to the terms and conditions of the license granted by D-Link for the Software. Replacement Software will be warranted for the
remainder of the original Warranty Period and is subject to the same limitations and exclusions. If a material non-conformance is incapable
of correction, or if D-Link determines in its sole discretion that it is not practical to replace the non-conforming Software, the price paid by
the original licensee for the non-conforming Software will be refunded by D-Link; provided that the non-conforming Software (and all copies
thereof) is first returned to D-Link. The license granted respecting any Software for which a refund is given automatically terminates.
Non-Applicability of Warranty:
The Limited Warranty provided hereunder for Hardware and Software portions of D-Link’s products will not be applied to and does not cover
any refurbished product and any product purchased through the inventory clearance or liquidation sale or other sales in which D-Link, the

“As-Is” without any warranty whatsoever including, without limitation, the Limited Warranty as described herein, notwithstanding anything
stated herein to the contrary.

the customer in resolving any suspected defects with the product. If the product is considered defective, the customer must
