Threshold Level
When case 1 or 2 below is satisfied, the Storage Server begins deleting video files, starting
with the earliest ones. The Storage Server keeps recording video. At the same time, the
Storage Server generates event notification.
1) When the Storage Server disk space used exceeds the following value:
a. If [Setting value of Maximum disk space used] is 128MB or more,
[Setting value of Maximum disk space used] - 32MB
b. If [Setting value of Maximum disk space used] is 128MB or less,
[Setting value of Maximum disk space used] * 3/4
2) When free disk space falls below the following value:
a. If [Setting value of Maximum disk space used] is 128MB or more,
(Number of camera + 2) * 32MB
b. If [Setting value of Maximum disk space used] is 128MB or less,
(Number of camera + 1) * 32MB + ([Setting value of Maximum disk space used] * 1/4)
Limit Level
When case 1 or 2 below is satisfied, the Storage Server stops recording video. At the
same time it generates event notification. Even though the Storage Server has started
deleting video files when the 'Threshold Level' is reached, recording will stop at the time
when the 'Limit Level' is achieved.
Storage Server resumes recording when the free disk space rises above the 'Limit Level'.
1) When the Storage Server disk space used exceeds the following value:
a. [Setting value of Maximum disk space used]
2) When free disk space falls below the following value:
b. (Number of camera + 1) * 32MB
The following is a table of values for each level calculated based on the above examples.
Disk Drive Low Disk Warning Level
1) 40GB * (100-10) / 100=36GB
C Drive
2) 100GB * 10 / 100=10GB
1) 200GB * (100-10) / 100=180GB
D Drive
2) 200GB * 10 / 100=20GB
Calculations referenced by 1) refer to disk space used by the Storage Server.
Calculations referenced by 2) refer to disk space remaining.
'Threshold Level' can be used as a protective level so that the 'Limit
Level' is not achieved. It is recommended that you take measures when
Note
'Low disk warning level' event notification is generated, such as
deleting unnecessary video files.
You will receive email notifications when events are generated at
respective levels, if configured to do so (
