Storage Device
Once a formatted SD card has been inserted in the SD memory card slot, it is automatically mounted and information such as
the available space and the size of the storage device is shown. The disk is full when there is less than 1000KB of space left on
the memory card.
Disks are normally preformatted when purchased, if a SD Card needs to be formatted click the Format button to format the
disk. Any previous data stored on the disk will be lost. Mounting is done automatically when a new memory card is inserted, or
when the system boots. The only time you need to do a manual mount, is when you have executed an unmount command and
the memory card has not been ejected and reinserted.
Status shows as follows:
OK - The storage device is mounted and working correctly
•
connected - The storage device is present but not mounted
•
disconnected - The storage device is not present.
•
failed - A problem has been discovered.
•
If the status shows as failed, click Check disk to see if the problem can be found and then try Repair. As a final measure the
storage device might need to be reformatted. If there is important data on the storage device, see Troubleshooting, on page 49.
Read only shows the status of write-protect tab on the memory card. The status no means the tab is in the write-enabled
mode and recordings can be saved to the memory card. The status yes means the memory card's tab is in the
write-protected/read-only position, or there is a system error and recordings cannot be saved to the memory card.
Important!
To prevent loss of data, click Unmount before removing a storage device.
Storage Device Settings
Storage Device Settings is used to configure removal of recorded video.
Automatic disk cleanup
To avoid filling up local storage, Automatic disk cleanup can be set to continually remove older recordings to create more
space.
Once enabled, automatic disk cleanup can be set to remove recordings that are older than a set number of days or weeks and
when a percentage of the disk is full. For longer or continuous recordings, the oldest part of the recording is removed, it is
recommended to have a time and date overlay in the video for proper tracking of recordings. See Overlay Settings, on page 17.
Note:
For continuous recording to work properly, do not set the limit to more than 80% full.
Interrupted recordings with an Unknown status, partial recordings and any other recording that has not been removed by disk
cleanup can be removed manually from the Recording List using the Remove button.
Check Lock disk to stop writing to the disk and protect recordings from being removed. A locked disk cannot be formatted.
