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. 

Select to stream video or audio data or both. This is enabled only when the video mode is set to H.264.

Depending on your network environment, there are four transmission modes of H.264:

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 video server 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 video server 

while serving multiple clients at the same time. Note that to utilize this feature, the video server must be 

configured to enable multicast streaming at the same time. For more information, please refer to  RTSP 

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.
