H.265/H.264 Protocol Options
Depending on your network environment, there are four transmission modes of H.264 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 106.
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.
