D-Link DVS-301 User Manual

Building Networks for PeopleDVS-301 User Manual v1.00 33There are two settings for the client side. One is “Media Option”. You can mute the audio bychecking this option. The other is “Protocol Option”. You can choose the connection protocolbetween client and server by this option. There are three protocols - UDP, TCP and HTTP.When you choose UDP protocol, audio and video streams can be more real-time. But somepackets may be lost and decoding error will happen. If you select TCP protocol, packet loss isn’toccurred and decoder will run normally. But the real-time issue is worse than UDP protocol. Ifyour environment is behind the firewall and it opens HTTP port (80) only, you can select HTTPprotocol only. In this mode, audio will not be sent and you just can see the video only. If youdon’t know which protocol you should choose, select the UDP protocol and the client will trythese protocols in this order, UDP TCP HTTP. After the client connects to the VideoServer successfully, “Protocol Option” will be set as the working protocol automatically.
