DCS-2100G User's Manual Connection Type Using the DCS-2100G with an Internet Browser Media Option: Protocol Option: D-Link Systems, Inc. Allows a user to disable audio when viewing video. The UDP Protocol should be chosen for the most users. Generally, the client computer will automatically try these protocols in the following order, UDP -> TCP -> HTTP. After the client connects to the DCS-2100G successfully, the working protocol will be displayed in Protocol Option. The chosen protocol will be recorded in the user's 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. HTTP Protocol - If the network is protected by a firewall and it opens HTTP port (80) only, HTTP protocol must be selected. In this mode, audio is disabled and only video can be viewed. TCP and UDP connections will not be available to remote users if all four ports have not been forwarded (as shown on page 41). Only the HTTP port must be forwarded for remote users to make an HTTP connection (video only). 45
