Set Maximum Recording Days

NVR 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”.

For more deletion rules explanation, please refer to Storage Settings - Set Recording

Deletion Rule on page 58.

Check Disk Status

Hard disk failure often comes after detectable signs and thus can be predicable, thus it is

important to detect these signs long before they really cause disk failures.

NVR performs S.M.A.R.T. Disk check on 24-hour basis since last check. This technology

enables a system to monitor the disk status and anticipate disk failures, helping the system

administrator to prevent from unexpected outage and data loss.

You may manually perform an instant S.M.A.R.T check by clicking “Refresh”.

Once the S.M.A.R.T status of disk appears “WARNING”, “FAILED”, or “UNKNOWN” instead

of “PASSED”, it is not reliable for recording, and may fail when the number of bad sectors on

the disk has grown high enough. Please

1. Click “Disable” next to Recordable status to stop the system from saving recording into

it.

2. Immediately export important video and system log, and then replace the disk following

the instructions Manage Abnormal Disks on page 60.
