Video Stream

The Maximum video stream time can be set as Unlimited, or set a maximum stream time per session in seconds, minutes or hours. When the set time has expired, a new stream on the Live View page can be started by refreshing the page in the web browser. Note that the maximum video stream time does not apply to clients connecting via multicast.

To avoid bandwidth problems on the network, the frame rate allowed to each viewer can also be limited. Select either Unlimited or define a maximum frame rate per viewer.

MPEG-4 settings

You can adjust the MPEG-4 settings and control the video bit rate on this page.

The MPEG-4 standard provides many different coding tools for various applications in different situations. As most MPEG-4 clients do not support all these tools, it is usual to instead define and use subsets for different clients or groups of clients. These settings allow you to define the type of viewing client to use.

Adjusting the maximum bit rate and setting it to a variable or constant is a good way of controlling the bandwidth used by the MPEG-4 video stream.
