I compared to my working filter. I have mine set to 51%, sorting by Date/Time (instead of Id as you have) and limit to 5 events at a time. Other that I see no difference. But you are right that it seems strange that events get deleted even though the disk is just 2% full. What if you change from 8% ...

What that rule says is:

If disk is occupied more than 8%, delete the last 100 events.

So, if you have less than 100 events, everything will be deleted.

Set the number of event to 5 or something like that, then zm will delete 5 events at a time until it reaches below 8% full.

I assumed zoneminder did log login failures, but it seems to only log successful logins. That was a disappointment to me.

I think fail2ban can be used, it can be used to prevent brute force attacks for anything that posts log messages at failed login (the log does however need to contain the IP address, not sure if zoneminder writes it to the log).

When using a network camera it does not matter whether it is "linux compatible" or not. As long as the camera can provide a network video or image source it can work with zoneminder.

It's different when using USB cameras.

There are some security settings in Apache that I think makes sure that the files need to be owned by the user the web server is run as. But if the /zm alias works it doesn't really make sense...

There is a package called Backup Ninja that I find easy to set up. It's a daemon and then there are different "recepies" for different kind och backups. It can't do all tricks, but for most uses I find it useful. For example I use one "recepie" to put mysql backups in a specified...

No event occurred the last hour?

More seriously, maybe it could be some time zone setting making zoneminder misinterpret the time of the events, but that seems unlikely because zoneminder should store and read events using the same time zone...

It seems that perhaps there have been some Apache security updates/changes since last time that I did this and I just cannot get it to work. What error messages did you get? (You DID look in the logs to see why it didn't work, didn't you?) And you did a full graceful reload of Apache to make it rea...

Without motion detection there's not problem with that setup, what takes computing power is the motion detection.

Is there a specific reason you have several zones? Have you activated statistics? (It's a good way to see what triggers your events.) It's also possible to get zm to highlight the triggering pixels (but maybe just in blob mode?). You should set a "max alarmed area" to filter out ambient li...

It's the image analysis that takes power. For each camera, ZM will have to keep at least two images in memory (that's where shared memory is used) and compare those images pixel by pixel. With more complex analysis additional computations have to be done. I can compare with my very old MythTV backen...

I just noticed a typing error

If the data is stored on the same disk, partitioning should not affect performance.

If the data is stored on the same disk, partitioning should affect performance. What affects performance is probably the use of another file system (reiserfs instead of ext3/ext4). On my machine the disk speed is not an issue, on my machine CPU and shared RAM for image analysis are the bottleneck. B...

Zoneminder stores everything in one specific location, if you want to avoind Zoneminder filling your disk you could put that location on a separate partition (or LVM logical volume, for scalability).

I think everything else would be covered by any linux partitioning guidelines.
