This chapter explains how to select the stream transmission mode and saving options at local
computer. When completed with the settings on this page, click Save on the page bottom to
take effect.
MPEG-4 Media Options
Select to stream video or audio data. This works only when the video mode is set to MPEG-4.
MPEG-4 Protocol Options
Depending on your network environment, there are four transmission modes of MPEG-4 streaming:
UDP unicast: This protocol allows for more real-time audio and video streams. However, network
packets may be lost due to network burst traffic 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, see RTSP
Streaming on page 34.
TCP: This protocol guarantees the complete delivery of streaming data and thus provides better video
quality. Nevertheless, the downside with 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 and you don’t need to open specific port
for streaming under some network environments. Users inside a firewall can utilize this protocol to allow
streaming data to come through.
