Just in the frames as far as I know.

In the monitor config under Storage change Save JPEGs to Frames + Analysis images (if available) When you view the frames it will have lines.
Note that will use more CPU and disk space.

I suspected there was not a "good" size, but asking is better than guessing.

I am about to rebuild my RAID group. Is there a stripe size that would be better?
Does ZM write events in any particular chunks?
For instance, MS SQL reads and writes in 64k blocks, so aligning the file system and stripe size to 64k makes a difference.

There is a thread about it.

I am running 22.04 and I am in no hurry to upgrade. There are no features in 24 that I need. I may not upgrade the OS until version 28. I have been doing this too long to rush into upgrades. As long as I am getting security patches I am good. What is your driving reason to upgrade? I am curious if I ...

You should also consider a reduced frame rate. Security video is frequently 10FPS and lower. TV shows are 24FPS. An 8MP camera @ 8FPS doing modect takes ~50% of one of my Xeon threads. That may help you. Another thing that will help later, increase your key frame rate. My key frames are once a ...

Camera FPS is important. You are not making a movie so set the FPS to around 5-10 on the cameras. Also, I set the keyframe to 1 per second. Not a hard rule, but 1 thread per motion detection works best in my experience. Camera passthrough is important. This reduces CPU work. CPU clock rate is ...

Be sure you tune WG. Packet size is very important. I ended up with an MTU of 1420 to get to 750Mb/s.
The VPN header takes some of the packet space.

free is showing a large cache. You have plenty of RAM. Each zone sensitivity can be set. There are several threads on adjusting zones. It can take a long time to get the first one right, after that the others will be easier. You will have learned a lot. One tip is to use pixels instead of percentage ...

It is not a bad question.
top reports only the "free" number. free reports all of the numbers.

How many monitors? What is reporting 300 MB of RAM free? I have 16GB of RAM and 14 monitors. 364MB free and 11,896MB available. So, I am not close to being out of RAM. free -m total used free shared buff/cache available Mem: 15896 3273 364 389 12259 11896 Swap: 4095 1367 2728

The hint on where to start helped. From the syslog: Sep 20 11:00:09 watcher fwupd[458986]: 16:00:09:0672 FuContext Failed to load SMBIOS: invalid DMI data size, got 3895 bytes, expected 7767 Sep 21 00:18:00 watcher systemd[1]: zoneminder.service: Failed with result 'oom-kill'. Sep 21 02:45:08 ...

Would that log as "Cannot write to event folder /zm/store1" in my case? I cannot find that in the log. Right now my log is full of cannot write errors because I changed the permissions to default. Should I delete default? I know is a past install I deleted default, but it did not go away. Thank you ...

For many years all events have been written to Store1 which is /zm/store1. Now ZM is trying to write events to /var/cache/zoneminder/events. I found out because it filled the boot drive and crashed ZM. What would make it not write to the configured location? The disk is no more full than it has been ...
