H.264 / MPEG-4 Protocol Options

Depending on your network environment, there are four transmission modes of H.264 or MPEG-4

streaming:

UDP unicast: This protocol allows for more real-time video streams. However, network packets may be

lost due to network burst trafc and images may be broken. Activate 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 45.

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

quality. The downside of this protocol is that its real-time effect is not as good as that of the UDP protocol.

HTTP: This protocol allows the same quality as TCP protocol without needing to open specic ports for

streaming under some network environments. Users inside a firewall can utilize this protocol to allow

streaming data through.
