Wireless Security
This section will show you the dierent levels of security you can use to protect your data from intruders.
The DCS-942L 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.

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.

Conguring the DCS-942L with a Router
D-Link’s DCS-942L is a versatile and cost eective Network Camera oering both video and audio monitoring. It can also serve as a powerful
surveillance system in security applications. The DCS-942L can be used with any wired or 802.11n/g wireless router. This section explains how to
view the camera from either the Internet or from inside your internal network.
Components Needed:
• 1 DCS-942L Network Camera
• 1 Ethernet Cable
• A Wired or Wireless router such as the D-Link DIR-655 Wireless Router
• Ethernet based PC for system conguration
Setting up the DCS-942L for Use Behind a Router
Installing a DCS-942L Network Camera on your network is an easy 4–step procedure:
1. Assign a local IP address to your network camera.
2. View the network camera using your Internet Explorer web browser.
3. Access the router with your web browser.
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-942L, follow the steps outlined in the Quick Install Guide.
After you have completed the setup of the DCS-942L 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.

1. Assign a Local IP Address to Your Camera
Run the setup wizard from the CD included with the DCS-942L. Follow the steps in the Quick Install Guide to congure the DCS-942L. 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.
2. View the Network Camera Using Your Internet Explorer Web Browser
Run your Internet Explorer Web browser. In the address bar, type in the IP Address that was assigned to the Network Camera by the DCC program.
The DCS-942L Live Video Page appears with a window displaying live video from the camera. You are able to view this screen from any PC running
Internet Explorer on your LAN.
Click on the Setup button on the left side of the display. Scroll to the bottom of the Network Setup page to display the ports used by HTTP and
Streaming audio and video.

Section 5 - Security
The Setup > Network page displays the port settings for your camera. If necessary, these ports can be changed if they are already in use by other
devices (e.g. in a multiple camera environment).
Note: Both the HTTP port and RTSP port are required to be opened for the DCS-942L.

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.
49D-Link DCS-942L 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-942L over the Internet. The router
connects to the Internet over a series of numbered ports. The ports normally used by the DCS-942L 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.
