Motion Detection Mode
When recording upon Motion Detection, assign no more than 10 channels to each hard
disk to ensure stability. The table below shows the number of days you can record in 20
2TB hard disks when using Motion Detection mode.
In this example, since the 20 hard disks cannot be evenly distributed among 13 storage
groups, some storage groups will be assigned 1 hard disk while other storage groups will be
assigned 2 hard disks. The number of hard disks assigned for a storage group may
depend on the actual environments. You may assign more hard disks to the group that
would have more motion events.
