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 transmission modes of 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 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, please refer to
RTSP Streaming on page 69�
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 specific ports for
streaming under some network environments� Users inside a firewall can utilize this protocol to allow
streaming data through�
