6.6.6 Hard Disk
Figure 6.24 System - Hard disk
The Hard Disk menu gives access to settings that affect video retention as well as a means to
format the hard disk.
– Overwrite allows the unit to continuously record, overwriting the oldest unprotected
video on the hard disk with newer video.
– The Disk full warning sets the threshold as which point the unit triggers an alarm
indicating the drive is nearly full. This setting has no effect when Overwrite is in use.
– By default, the disk has only one partition where Continous and Event recordings are
stored. This is the case when Event Partition is set to 0%.
– The disk can be segmented into two partitions by setting the Event Partition to a value
greater than 0%. The first partition then stores video from Continuous Recording; the
second partition the events recording. The Event Partition specifies the percentage of
the hard disk dedicated to preserving video from Inputs and Motion.
– Auto delete sets a time window outside of which all video will be deleted from the unit.
This function is primarily reserved to meet legal requirement in some jurisdictions.
– Format erases all data from the selected partition.
