By default setting, all devices are assigned to the default recording group� You can manually
remove a device from the default recording group� However, only those devices which belong to
a recording group can produce recorded media data�
Another purpose of setting recording group is that you can distribute the recording loads
to a number of hard-disks on the server side� The live media data will be stored in the rst
assigned hard-disk initially, and when the available free space of the rst hard-disk approaches
to the preset reserved space, the media data will be stored in the second disk, and so on� If
the available spaces of that last disk approaches to the reserved spaces, the recorded data
in the rst disk will be erased for recording new media data� This procedure is called "Cyclic
Recording"�
