5. 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.

6. The images are poor quality, how can I improve the image quality?

Make sure that your computers 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 Internet Camera image display is incorrect. Through the Web Configuration Video section

of the Web management you need to adjust the image 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?

The 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 of lower than 5, then you will need to upgrade your Web browser

software in order to view the streaming video transmitted by the Internet Camera.

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.

* Wireless is available only for the DCS-920

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.
