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 wal s and ceilings between your adapter and other network devices (such as your Network Camera) - each
wall or ceiling can reduce your adapterās 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 difference. 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 drywal or open doorways. Materials
and objects such as glass, steel, metal, wal s with insulation, water (fish tanks), mirrors, file cabinets, brick, and concrete wil 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. D-Link DCS-942L User Manual 12 Section 2 - Installation Camera Installation Wizard

This section will show you the different levels of security you can use to protect your data from intruders.
The DCS-942L offers the following types of security:
ā¢ WPA-PSK (Pre-Shared Key) ā¢ 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
ā 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-942L User Manual 44 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 havenāt 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 computerās 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. D-Link DCS-942L User Manual 45 Section 5 - Security Configuring the DCS-942L with a Router
D-Linkās DCS-942L is a versatile and cost effective Network Camera offering 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.
ā¢ 1 DCS-942L Network Camera ā¢ 1 Ethernet Cable ā¢ A Wired or Wireless router such as the D-Link DIR-655 Wireless Router ā¢ Ethernet based PC for system configuration Setting up the DCS-942L for Use Behind a Router
Installing a DCS-942L Network Camera on your network is an easy 4āstep 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 Installation Guide.
After you have completed the setup of the DCS-942L outlined in the Quick Instal ation Guide you wil 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. D-Link DCS-942L User Manual 46 Section 5 - Security 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 Installation Guide to configure 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. D-Link DCS-942L User Manual 47 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. D-Link DCS-942L User Manual 48 Section 5 - Security Router Set-Up and Installation
The fol owing steps general y 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
dynamical y assigned WAN IP Address. āDynamicā means that your routerās
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 routerās 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 routerās Status > Device Info page. D-Link DCS-942L User Manual 49 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 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-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 configure your routerās Virtual Server settings:
1. Click Enabled. 2. Enter a different name for each entry. 3. Enter your cameraās 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. D-Link DCS-942L User Manual 50 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 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. D-Link DCS-942L User Manual 51 Section 6 - Troubleshooting Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DCS-942L. Read the following descriptions if you are having problems. (The examples below are illustrated in Windows VistaĀ® and XP. If you have a different
operating system, the screenshots on your computer will look similar to the following examples.) 1. What is Remote Access? How do I enable it? Remote Access allows you to access your camera from any PC connected to the Internet through a web browser. This lets you view your camera
feed and manage your cameraās settings when youāre away from home. To enable Remote Access, simply go through the Camera Installation Wizard included on the Installation CD that came in your package. You can
also download the wizard from the following websites: DCS-942L: http://DCS-942L.mydlink.com After going through the wizard, you should see Remote Status: Enabled on the summary page. If you see Remote Status: Disabled, make sure that: ...the front LED on your camera is lit solid green ...your Internet connection is working ...your routerās LAN & WAN connections are working properly ...your router has UPnP enabled (if your router does not support UPnP, please refer to Appendix A) ...your router can get a public IP ...your router is upgraded to the latest firmware ...you have tried rebooting your router by unplugging it, then plugging it back in After checking the above items, you can click the Retry button to refresh the summary screen to see if Remote Access has been enabled. 2. What can I do if I forget my password? If you forget your password, you will need to perform a hard reset of your camera. This process will change all your settings back to the factory
defaults. To reset your camera, please use an unfolded paperclip to press and hold the RESET button for at least 3 seconds while your camera is plugged in. 3. In addition to using mydlink.com, is there another way to access my camera remotely over the Internet? D-Link DCS-942L User Manual 52 Section 6 - Troubleshooting
Yes, you can access your camera over the Internet through the fol owing URL after successful y instal ing your camera through the Camera Instal ation
Wizard: http://[mydlink No.].mydlink.com For example, if your cameraās 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 cameraās password. After entering your password, your cameraās
Live View window will open, and you will be able to configure your camera as well. 4. 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 36 for information about how to
enable the LED. 5. Why is the cameraās 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 (ā¦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. 6. 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 isnāt 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. D-Link DCS-942L User Manual 53 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 computerās 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. 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. 11. The PIR is no operation well, how can I improve the PIR quality?
- For the Passive Infrared Sensor (PIR) to function properly it is required to have direct line of site to the object. When the room has many
obstacles or the line of site is obstructed by glass, the PIR will not function properly.
- When the environment temperature is too high, the PIR detection will slow down and should not be mistaken for a faulty PIR. - This Network Camera can only be installed indoors. Do not install this camera in a place where IR interference can be a problem. IR
interference can be found close to glass doors or windows, where direct sunlight can cause interference or in the path of car headlights. D-Link DCS-942L User Manual 54 Section 6 - Troubleshooting
- Do not install this camera next to or in front of an air conditioner outlet or vent. - Do not install this camera close to wireless devices with high frequencies as the PIR is easily affected by RF radiation. - The PIR functions at best when detecting lateral movements. Radial movements cannot be detected as well as lateral movements. - Do not install this camera directly under an extreme bright light. The PIR cannot fully suppress a bright white light. - Any movements from an object with a normal body temperature, like humans or animals, can be detected. To avoid any malfunctions, install
this camera at the proper height.
- To avoid any malfunctions, install this camera in an environment with an average temperature of 25Ā°C. Only within a distance of 2.5 meters
can smaller movements of an object, with the average adult humanās height, be detected. Between a distance of 2.5 and 5 meters, a larger
movement of an object is required for detection.
- Install this camera on a firm, static, anti-shock surface. D-Link DCS-942L User Manual 55 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 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. D-Link DCS-942L User Manual 56 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 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. Who uses wireless? Wireless technology as become so popular in recent years that almost everyone is using it, whether itās for home, office, business, D-Link has a D-Link DCS-942L User Manual 57 Appendix A - Wireless Basics

Wireless technology is expanding everywhere not just at home or office. People like the freedom of mobility and itās 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 āhotspotsā. 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 youāre installing it for the first time it could be quite a task not knowing where to start. Thatās why weāve 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 Donāt 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. D-Link DCS-942L User Manual 59 Appendix A - Wireless Basics Wireless Modes
There are basically two modes of networking:
ā¢ Infrastructure ā All wireless clients will connect to an access point or wireless router.
ā¢ Ad-Hoc ā Directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each computer, such as two
or more DCS-942L 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. D-Link DCS-942L User Manual 60 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 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 firewal software
programs may block a DHCP request on newly instal ed 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. D-Link DCS-942L User Manual 61 Appendix B - Networking Basics 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 WindowsĀ® 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 routerĀ“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. D-Link DCS-942L User Manual 62 Appendix C - Technical Specifications Technical Specifications SYSTEM REQUIREMENTS SDRAM
