DETEXI NVR Server & Configuration
11.
When I search my archives, I do not have video for as many days as I have told the NVR to save data for, even though I have been recording for longer.
If archived video is not kept for as long as is defined in the NVR configuration, the storage directory does not have enough space available to hold as many days of video as desired. If the archive
Free Space Minimum setting defined on the
Global Settings Tab of the NVR Setup application is ever reached, archives will be overwritten as needed to keep that minimum of free space available, regardless of how many days worth of video are saved.
It is highly recommended that either the retention time in days (
Keep Information for [ ] Days setting) is adjusted, or more storage is made available to the system to remedy this problem. Constant overwriting (rather than cleaning up old data once a day as in normal operation) is very hard on the hard drive, and much more processor intensive. The
DETEXI Storage Calculator, found on the installation disk, should be used to estimate how much storage is required based on the desired recording specifications.
