Wireless Installation Considerations
The D-Link Wireless Network Camera lets you access your network using a wireless connection from anywhere within the operating range of your
wireless network. However, 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. Minimize the number of walls and ceilings between your adapter and other network devices (such as your Network Camera) - each
wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters).
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 your 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 dierence. A solid metal door or aluminum studs may weaken the wireless signal. Try to position your
access points, wireless routers, and other networking devices where 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 at least 3-6 feet or 1-2 meters away from electrical devices or appliances that generate RF noise.
5. If you are using 2.4GHz cordless phones or other radio frequency sources (such as microwave ovens), 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.

Section 5 - Security
Wireless Security
This section will show you the dierent levels of security you can use to protect your data from intruders.
The DCS-940L oers 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 dened 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 dened so that you can change keys easily.
37D-Link DCS-940L User Manual
Section 5 - 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-specic MAC address, which is relatively simple to be snied 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.

4. Open virtual server ports to enable remote image viewing.
Note: These are manual steps; however, if you decide to use the wizard, it will perform every step automatically.
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-940L, follow the steps outlined in the Quick Installation Guide.
After you have completed the setup of the DCS-940L 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 congured to allow remote viewing of the camera
over the Internet.

Router Set-Up and Installation
The following steps generally apply to any router that you have on your network. The D-Link DIR-655 is used as an example to clarify the conguration
process. Congure the initial settings of the DIR-655 by following the steps outlined in the DIR-655 Quick Installation Guide.
3. 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 identies your router
on the public network and allows it to access the Internet. To nd 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.
42D-Link DCS-940L User Manual
Section 5 - 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 xed 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 rewall security features built into the DIR-655 router prevent users from accessing the video from the DCS-940L over the Internet. The router
connects to the Internet over a series of numbered ports. The ports normally used by the DCS-940L 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 DIR-655 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 congure your router’s Virtual Server settings:
1. Click Enabled.
2. Enter a dierent name for each entry.
3. Enter your camera’s local IP Address (e.g., 192.168.0.120) in the Private IP eld.
4. Select TCP for HTTP port, both (TCP and UDP) for RTSP and both (TCP and UDP) for 5556 - 5559 ports.
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.
43D-Link DCS-940L User Manual
Section 5 - 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 trac 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 specic 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 name on the Virtual Server List
to enable your settings.

Section 6 - Troubleshooting
3. In addition to using mydlink.com, is there another way to access my camera remotely over the Internet?
Yes, you can access your camera over the Internet through the following URL after successfully installing your camera through the Camera Installation
Wizard:
http://[mydlink No.].mydlink.com
For example, if your camera’s mydlink No. was 12345678, you would be able to access your camera remotely by opening your web browser and
going to http://12345678.mydlink.com
This URL will open a webpage where you will be asked to log in by entering your camera’s password. After entering your password, your camera’s
Live View window will open, and you will be able to congure your camera as well.
4. Why does the LED not light up?
The power supply might be faulty. Conrm that you are using the provided DC 5V power supply for this network camera. Verify that the power
supply is correctly connected.
5. Why is the camera’s network connection unreliable?
There might be a problem with the network cable. To conrm that the cables are working, PING the address of a known device on the network. If
the cabling is OK and your network is reachable, you should receive a reply similar to the following (…bytes = 32 time = 2 ms).
Another possible problem may be that the network device such as a hub or switch utilized by the Network Camera is not functioning properly.
Please conrm the power for the devices are well connected and functioning properly.
6. Why does the Network Camera work locally but not remotely?
This might be caused by the rewall protection. Check the Internet rewall with your system administrator. The rewall may need to have some
settings changed in order for the Network Camera to be accessible outside your local LAN. For more information, please refer to the section about
installing your camera behind a router.
Make sure that the Network Camera isn’t conicting with any Web server you may have running on your network.
The default router setting might be a possible reason. Check that the conguration of the router settings allow the Network Camera to be accessed
outside your local LAN.
46D-Link DCS-940L User Manual
Section 6 - Troubleshooting
7. Why does a series of broad vertical white lines appear through out the image?
It could be that the CMOS sensor (a square panel situated behind the lens that measures the light signals and changes it into a digital format so
your computer can present it into an image that you are familiar with) has become overloaded when it has been exposed to bright lights such
as direct exposure to sunlight or halogen lights. Reposition the Network Camera into a more shaded area immediately as prolonged exposure to
bright lights will damage the CMOS sensor.
8. The camera is producing noisy images. How can I solve the problem?
The video images might be noisy if the Network Camera is used in a very low light environment.
9. The images are poor quality, how can I improve the image quality?
Make sure that your computer’s display properties are set to at least 6-bit color. Using 16 or 256 colors on your computer will produce dithering
artifacts in the image, making the image look as if it is of poor quality.
The conguration on the Network Camera image display is incorrect. The Web Conguration Video section of the Web management allows you to
adjust the related-parameters for improved images such as: brightness, contrast, hue and light frequency. Please refer to the Web Conguration
section for detailed information.
10. Why are no images available through the Web browser?
ActiveX might be disabled. If you are viewing the images from Internet Explorer make sure ActiveX has been enabled in the Internet Options menu.
You may also need to change the security settings on your browser to allow the ActiveX plug-in to be installed.
If you are using Internet Explorer with a version number lower than 6, then you will need to upgrade your Web browser software in order to view
the streaming video transmitted by the Network Camera.

Appendix A - Wireless Basics
Wireless Basics
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 oce environments, and public areas such as airports, coee shops and universities. Innovative ways
to utilize WLAN technology are helping people to work and communicate more eciently. Increased mobility and the absence of cabling and other
xed infrastructure have proven to be benecial 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.
48D-Link DCS-940L User Manual
Appendix A - Wireless Basics
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 oce 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 aord. 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 dierent 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
49D-Link DCS-940L User Manual
Appendix A - Wireless Basics
manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and many other outdoor venues.
Who uses wireless?
Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, oce, business, D-Link has a
wireless solution for it.
Home
• Gives everyone at home broadband access
• Surf the Web, check email, instant message, and etc
• Gets rid of the cables around the house
• Simple and easy to use
Small Oce and Home Oce

Appendix A - Wireless Basics
Where is wireless used?
Wireless technology is expanding everywhere not just at home or oce. People like the freedom of mobility and it’s becoming so popular that more
and more public facilities now provide wireless access to attract people. The wireless connection in public places is usually called “hotspots”.
Using a D-Link Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote locations like: Airports, Hotels,
Coee Shops, Libraries, Restaurants, and Convention Centers.
Wireless network is easy to setup, but if you’re installing it for the rst 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
signicantly 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.
51D-Link DCS-940L User Manual
Appendix A - Wireless Basics
Wireless Modes
There are basically two modes of networking:
• Infrastructure – All wireless clients will connect to an access point or wireless router.
• Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each computer, such as two
or more DCS-940L wireless network Cardbus adapters.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect to the wireless router or access point.
An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters. All the adapters must be in Ad-Hoc mode to communicate.

Appendix B - Networking Basics
Networking Basics
Check your IP address
After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless
router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click OK.
At the prompt, type ipcong and press Enter.
This will display the IP address, subnet mask, and the default
gateway of your adapter.
If the address is 0.0.0.0, check your adapter installation, security
settings, and the settings on your router. Some rewall software
programs may block a DHCP request on newly installed
adapters.
If you are connecting to a wireless network at a hotspot (e.g.
hotel, coee shop, airport), please contact an employee or administrator to verify their wireless network settings.
