This chapter explains how to select the stream transmission mode and saving options on the
local computer. When completed with the settings on this page, click Save on the page bottom
to enable the settings.
H.264 / MPEG-4 Media Options
Select to stream video or audio data or both. This is enabled only when the video mode is set to H.264 or
MPEG-4.
H.264 / MPEG-4 Protocol Options
Depending on your network environment, there are four options with the transmission protocols with
H.264 or 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 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 87.
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 using 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 behind a rewall can utilize this protocol to allow
camera’s streaming data to pass through.
