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 or 

MPEG-4.

Depending on your network environment, there are four options with the transmission protocols with 

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 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 67.

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 using 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 behind a firewall can utilize this protocol to allow 

camera’s streaming data to pass through.
