If you have a large number of cameras streaming in multicast, you can improve your system performance by assigning a different multicast port number to each camera on your system.

What you should know

There is a known issue that causes Windows to use a lot of CPU to process multicast packets when they are on the same port. This issue effectively limits the maximum throughput on a single port at around 100 Mbps. By default, the system only increments the multicast address assigned to every video encoder it discovers, not the port numbers. If you frequently use multicast, you should also change the port number. For example, if you use Auxiliary Archiver roles or if everything is recorded in multicast.

Procedure

To change the multicast port on all video encoders:

  1. Open the Video task, and select the Archiver role to configure.
  2. Select the Media Router and click the Properties tab.
  3. In the Multicast section, turn on the Increment ports option.
  4. Click Apply.

To change the multicast port on a specific video encoder:

  1. Open the Video task, and select the Archiver role to configure.
  2. Select the camera to configure, and click the Video tab.
  3. In the Network settings section, beside Multicast address, set the port number you want to use.
  4. Click Apply.
  5. To restart the video unit, select the unit in the roles and units view, and click Reboot () in the toolbar.
    NOTE: If the new port is being used by another stream, your change is automatically reverted.
