Section 3 - Configuration
After you have completed the setup of the DCS-932 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.
1. Assign a Local IP Address to Your Camera
Run the Setup Wizard program from the CD included with the DCS-932. Follow the steps in the Quick Installation Guide to configure the
DCS-932. 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 (192.168.0.120 is only an example). You will probably have a different IP Address.

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-932 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 64bit 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-932 User Manual

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.

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
configuration process. Configure 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
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-932 User Manual
45
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 DIR-655 router prevent users from accessing the video from the DCS-932 over the Internet. The
router connects to the Internet over a series of numbered ports. The ports normally used by the DCS-932 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 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 Private IP field.
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.

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 name on the Virtual
Server List to enable your settings.

Troubleshooting
1. Why does the LED not light up?
The power supply might be faulty. Confirm that you are using the provided DC 5V power supply for this network camera. Verify that the
power supply is correctly connected. If the camera is functioning normally, the LED may have been disabled. See page 30 for information
about how to enable the LED.
2. Why is the camera’s network connection unreliable?
There might be a problem with the network cable. To confirm 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 confirm the power for the devices are well connected and functioning properly.
3. Why does the Network Camera work locally but not remotely?
This might be caused by the firewall protection. Check the Internet firewall with your system administrator. The firewall 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 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 Network Camera to be
accessed outside your local LAN.
4. 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.

5. 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.
6. 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 configuration on the Network Camera image display is incorrect. The Web Configuration 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
Configuration section for detailed information.
7. 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

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 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.

Where is wireless used?
Wireless technology is expanding everywhere not just at home or office. 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, Coffee Shops, Libraries, Restaurants, and Convention Centers.
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.

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-932 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.

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 ipconfig 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
firewall 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, coffee shop, airport), please contact an employee or administrator to verify their wireless network settings.

Statically Assign an IP address
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below:
Step 1
Windows® Vista - Click on Start > Control Panel > Network and Internet > Network and Sharing Center > Manage Network Connections.
Windows XP - Click on Start > Control Panel > Network Connections.
Step 2
Right-click on the Local Area Connection which represents your D-Link network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click Properties.
Step 4
Click Use the following IP address and enter an IP address that is on the same subnet as your
network or the LAN IP address on your router.
Example: If the router´s LAN IP address is 192.168.0.1, make your IP address 192.168.0.X where X
is a number between 2 and 99. Make sure that the number you choose is not in use on the network.
Set Default Gateway the same as the LAN IP address of your router (192.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The Secondary DNS
is not needed or you may enter a DNS server from your ISP.
Step 5
Click OK twice to save your settings.
