Useful Features
•
The capacity of the hard disk will be reduced by
approximately half when mirroring is set up. It is therefore
necessary to take care when setting recording times.
•
Mirroring can only be set up for the built-in hard disk, and is
not possible on the external hard disk.
•
Setting the system for mirroring is not a guarantee that
data will not be damaged.
•
All events logged on the built-in hard disk and the external
hard disk will be deleted when mirroring is set up. It is
therefore necessary to take back-ups of all important
events beforehand.
•
Depending on the recording settings and the operational
status, there is a possibility that playback speed will be
reduced and that the sound will not be synchronized with
the images when setting up the system for mirroring. This
is not a malfunction.
•
If a power failure occurs which the mirroring settings
enabled, the re-creation process will be carried out once
again in the background. The safety of the recorded data
cannot be guaranteed while the recreation process is being
performed.
•
Depending on the condition of the hard disk, there is a
possibility that the mirroring settings will fail. In this event,
cancel the mirroring settings, and then begin the setup
process once again.
•
Recording and playback is not possible when the mirroring
settings are being processed.
•
As the hard disk capacity displayed on the screen is
calculated as 1GB = (1024)
3
bytes, a lower capacity than
actually exists will be displayed.
•
If a defect occurs on one of the hard disks, the function for
exporting data onto DVDs will not operate.
•
The objective of mirroring is to protect recorded data in the
event that the VR-509 hard disk malfunctions. Note that
there are cases where operations cannot be continued
even when mirroring has been set up depending on the
case of hard disk malfunction.
It is possible to delete only the alarm lists without disturbing the
alarm recorded images.
