Client Settings

This chapter explains how to select the stream transmission mode and saving options on the local computer. When finished with the settings on this page, click Save on the page bottom to enable the settings.

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 for MPEG-4 streaming:

UDP unicast: This protocol allows for better real-time audio and video streams. However, network packets may be lost due to network burst traffic and images may be broken. Activate the 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, see RTSP Streaming on page 34.

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 for the same transmission quality as the 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.
