Hardware Overview

Antenna Connector

One antenna is included with the DCS-5220. It is fastened onto the antenna connector located on the back panel, which is used to provide a connection with a wireless network.

Microphone

The DCS-5220 Internet Camera has a built-in internal microphone.

Power LED

As soon as the power adapter is connected to the camera, the red LED and the green LED light will both appear steady on. As the camera is booting, a flashing red LED and steady green LED light will appear next.

The red LED will be turned off during self-test. Upon passing the self-test, a steady red LED and flashing green LED light will appear, indicating a good connection to the Ethernet port.

Wireless Installation Considerations

The D-Link Wireless PT Internet Camera lets you access your network using a wireless connection from virtually anywhere within the operating range of your wireless network. Keep in mind, however, that 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. Keep the number of walls and ceilings between the D-Link adapter and other network devices to a minimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized.

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 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 have a negative effect on range. Try to position access points, wireless routers, and computers so that the signal passes through drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water

(fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.

4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.

5.If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems), 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.

Enabling UPnP for Windows® XP

UPnP (Universal Plug and Play) is a networking architecture that provides compatibility among networking equipment, software, and peripherals. The DCS-5220 is an UPnP enabled Internet camera. If your operating system is UPnP enabled, the device will be easier to configure. If you do not want to use the UPnP functionality, it can be disabled by unchecking the Enabled UPnP checkbox in the Advanced > Network page (see page 32). Use the following steps to enable UPnP settings only if you are running Windows® XP. If you are running Windows® 98/2000, UPnP is not available.

Viewing Your DCS-5220

After all the router settings have been entered correctly, a PC user inside or outside your network will have access to the camera through the Internet Explorer Web browser. To access the camera from the Internet, type the IP Address of the router given to you by your ISP, followed by a colon, and the port number that you gave your camera (e.g., http://70.42.15.9:83). It is not necessary to enter the colon and port number if you are using the default Web server port 80. To access from a computer on your local (home) network, simply enter the local IP Address of the Camera followed by a colon and the port number (e.g., 192.168.0.120:83).

If you are following this manual in the order it is presented, you should now have an operating DCS-5220 Internet Camera configured with the Installer program. This section of the manual will cover how to use the Internet Camera in two methods:

•Using the DCS-5220 with an Internet browser and accessing the screens to control and monitor the camera.

•Using IP surveillance software with the DCS-5220.

Media Options: You can disable audio when viewing video, disable video while keeping audio, or have both video and audio present.

Protocol Options:

Most users should use the UDP protocol.

Generally, the client computer will automatically try these protocols in the following order, UDP -> TCP. After the client connects to the DCS-5220 successfully, the working protocol will be displayed in Protocol Options. The chosen protocol will be saved in your PC and used for the next connection. If the network environment is changed or users want to let the Web browser automatically detect the protocol, select UDP manually and click Save to change the setting and return Home to reconnect with the new setting.

Options:

UDP Protocol - Offers the highest image and video

quality. However, packet losses will diminish image quality when bandwidth becomes restricted. TCP Protocol - Packet loss is less likely to occur compared to UDP when bandwidth is restricted.

Consequently, to ensure detailed video quality (quantization rate) regardless of the network, it will utilize more bandwidth to send the maximal frames

Video quality control: Used when images change drastically.To fix the bandwidth utilization regardless of the video quality, choose
