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 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 66�

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�
