8. Can the DCS-5220 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-5220 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-5220

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 124 for more information.

10. Why am I unable to access the DCS-5220 from a Web browser?

If a router or ﬁrewall is used on the network, the correct ports for the DCS-5220 may not be conﬁgured on the

router or ﬁrewall. To correct the problem, you

need to determine if the DCS-5220 is behind a router or ﬁrewall and

if the router or ﬁrewall is properly conﬁgured for the ports the DCS-5220 is using. Refer to page 124 for help in

opening the correct ports on a router or ﬁrewall for use with the DCS-5220.

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 124 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 144).

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.

Appendix A - 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.
