In this mode, no video data is
written onto the data storage
device. This setting is useful if
you want to stop data from being
overwritten after an event.
In this mode, video data will be
redundantly stored on all data
storage devices with the
"Redundancy" setting. For this
purpose, the “Redundancy”
button in the “Recording
Parameter More Settings”
menu must be pressed.
Allocate the data storage device
to an HDD group.
Important:
If only one hard disk drive is installed and this is
set to "Read-only", the device cannot be used for
recording.
