Use of filters in Zoneminder

The filters in ZoneMinder have a very important role, they allow you to classify, archive and delete almost everything in Zoneminder, whether events, videos or images.

By default there are two functional filters:

• PurgeWhenFull*
• Updatediskspace*

First, the asterisk at the end of the title indicates to the user that the filter is linked to a cron job in order to operate repeatedly in the background, simply select the >>> run filters in the background.

PurgeWhenFull: Official Doc, allows you to empty the hard disk

Actions to select:

• Archive: archive events
• FilterUnarchiveEvents: Unarchive events
• Update used disk space: Update used disk space
• Make a video
• Execute a command
• Delete: Delete events
• FilterCopyEvents: Copy all events
• Move all Matches: move all events

Options to select

• launch filters in the background
• Run filter concurrently: Run filter concurrently
• Filter lock rows: lock rows

test

Then we click on execute and list matches in order to see the events concerned.

Conclusion

Well this tutorial is not complete, and I apologize, I waited so long to write this article that now I no longer use Zoneminder, why! This software is complete but the management of events, the configuration of the cameras is complex and frankly cannot be optimized.

Furthermore I have decided to stop using ZM. Why this changeover: since zm decided to stop the evolution of the ZMevenvnotification program in November 2021, suddenly it no longer has any real interest, especially since there has been a free NVR for Homeassistant for a while, it is is from Frigate, this project is young but already very promising.
