Important: Disk Space Management
In case of Threshold Level
The Storage Server continues recording video; however, it starts deleting the video files from the oldest one,
and generates an event.

Threshold Level
Tip
Old video files may be deleted even if these are within the [Maximum retained history] period.
However if the oldest file is currently used in the Viewer (for example for playback of recorded video), it
would not be deleted and the next oldest file will be deleted instead. Deletion will continue until the free
space rises above this threshold again.
See Chapter 7 for saving files.
In case of Limit Level
The Storage Server stops recording video when the free disk space goes down to this level, and generates an
event.
When the free disk space increases above this level by deleting old video files, the Storage Server resume
recording video and generates an event.
