Internal RAID (Redundant Array of Independent Disks) activates a redundant storage
mechanism (RAID 4) that ensures a higher reliability of recorded content. To activate the
RAID function, four harddisks must be installed and a RAID license activated. While
RAID 4 is active, the storage available for video recording is equal to three times the size
of the smallest disk in the set. The fourth disk is used for parity information.
If a single disk fails, no data is lost. Recording continues on three disks without RAID 4
protection. Once the defective disk has been replaced, the data on the new disk is rebuilt
(this process typically takes about 24 hours) while normal operation continues.
Overwrite after - The oldest video is automatically overwritten when the disk set is full.
Overwriting can be forced to a shorter time period if required, for example, for legal
purposes.
The total disk set capacity is shown in gigabytes.
