NVR 3.0 will keep recording file of specific device for the number of
days you set here. The default value is 30, if you want to modify it,
please check the box to start configuring it. Available value is among
1~999 days.
How to make proper storage arrangement
In NVR 3.0 system, there are two file-deleting mechanisms you can use based on different
needs. If both rules are set, the threshold reached earlier will execute the deletion first.
1. “Keep Recording Files for (1-999 days)” – Set this rule if you have more concern in
how long the recordings are kept, especially when you don’t want the old recordings to
stay longer in the system than a certain period.
2. “Reserve space” in the Disk Drive List on Setup page Storage tab - If the disk
space is more critical in your system, please give an approximate value here, the system
will always reserve this amount of space to store the newer recordings.
Given that you set the Reserve space as 30G, while Keeping Recording Files setting is 5
days, certain recording file will be deleted when it has been kept on disk for 5 days, despite
that there is still plenty of available disk space.
Before setting up the rules, you can make use of a handy storage calculator provided by
ACTi to find out the estimated storage your system requires on ACTi corporate website:
