MPEG-4 Media Options

Select to stream video or audio data or both� This is enabled 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, please refer to RTSP Streaming on page 46�

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�
