Format Hard Disks
Any newly- installed hard disk has to be formatted into ENR file system format. Click “ Format ”
to start formatting a new disk. After formatting, this disk will become ready for recording.
During normal operation, DO NOT REMOVE ANY DISK FROM THIS UNIT , or it might cause
damage to the disks. You can only remove or install a disk when the device is shut down.
Please note that the system will stop recording during the disk formation.
Storage Settings - Set Recording Deletion Rule
In ENR system, there are two file-deletion mechanisms:
1. User defined - Maximum Recording Days
ENR can keep recording files for a certain number of days defined by you . Set this rule if you
have more concern about how long the recordings are kept, especially when you do not want
the old recordings to stay longer in the system than a certain period. By default, this rule is
not activated, to modify it, check the box to input a number between 1~999 and click “ Apply ”.
2. Default - Automatic Disk Deletion
This is the default file deletion rule. When the total recordable disk space is full, an amount of
disk space for approximate ten-minute long recording will be cleared to save new recordings.
If you activate the “ Maximum Recording Days ” rule, either of the thresholds reached earlier
will execute the deletion first. Given that you set the Maximum Recording Days as 5 days,
the recording files that stay on the disks longer than this period will be deleted, despite that
there is still plenty of available disk space; on the other hand, if your disk space is not enough
to keep all the recordings for 5 days, ENR will still delete the oldest files whenever the space
is full.
Before setting up the rules, you can make use of a handy storage calculator provided by ACTi
to find out the estimated storage your system requires: http://www.acti.com/project_planner
Also, be careful when you apply the Maximum Recording Days setting, for ENR will execute
the deletion rule immediately whenever you click “ Apply ”, meaning that the all the recording
files kept longer than the last applied number of maximum days are just deleted in no time.
