on this page, click Save on the page bottom to take effect�

Stream Options

The Network Camera supports MPEG-4 and MJPEG dual streams� For more information,

please refer to Video settings on page 39�

MPEG-4 Media Options

Select to stream video or audio data� This works 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 trafc 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 congured to enable multicast streaming at the same time. For more information, see RTSP

Streaming on page 34�
