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 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  

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�
