MPEG-4 Protocol Options

Depending on your network environment, there are four transmission modes for MPEG-4 streaming:

UDP unicast: This protocol allows for better real-time audio and video streams� However, network

packets may be lost due to network burst trafc and images may be broken. Activate the UDP connection

when occasions require time-sensitive responses and the video quality is less important. Note that each

unicast client connecting to the server takes up additional bandwidth and the Network Camera allows up

to ten simultaneous accesses�

UDP multicast: This protocol allows multicast-enabled routers to forward network packets to all clients

requesting streaming media. This helps to reduce the network transmission load of the Network Camera

while serving multiple clients at the same time. Note that to utilize this feature, the Network Camera must

be configured to enable multicast streaming at the same time� For more information, please refer to

RTSP Streaming on page 36�

TCP: This protocol guarantees the complete delivery of streaming data and thus provides better video

quality. However, the real-time effect is not as good as that of the UDP protocol.

HTTP: This protocol allows for the same transmission quality as the TCP protocol without needing to

open specic ports for streaming under some network environments. Users inside a rewall can utilize

this protocol to allow streaming data through�
