Stream Options

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

please refer to Video settings on page 35�

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

RTSP Streaming on page 30
