I'm not sure what it depends on, but it depends.

I upgraded to 57, and have -- so far -- been having no problems with anything, including ZM and montage -- where everything's faster, and the datestamps in the scroller are a readable size now (where before they were in Flyspeck 3).

Indeed. To expand: if your camera is sending a stream in MPEG, not MJPEG, then ZM has to pick that apart into frames, so that it can do things like motion detection -- and if the encoding is dense, then that takes a lot of CPU, or it takes an FFMPEG that knows how to talk to hardware that does the d...

Turn your DHCP lease time down to 15 minutes, and then query the router by name?

That'll require some scraping on the router, probably, unless it's high-end enough to do SNMP.

D'oh. Yep, was thinking nocord, obviously.

Thanks much for the positive report; we always like to hear those. A 5 minute load average below 1 *per CPU core* is widely considered best. My experience of current Linuces is that you can get away with 2 per core pretty decently; at 3 per core you should start to worry. I have a Dell SC1430 that's...

I think I'm also going to do the Maria swap-in.

Ok, well, sure, bbunge, but MySQL says it's good up over 2GB, IIRC, and I'm peaking it at 500-something MB. Or did I misread the report? I don't particularly mind the exercise, but the bigger the hill it is to climb, the more justification I like to assemble for doing it, and I don't know that I'm t...

5 is the recommended rate; I can't imagine that's too fast for 2 cameras.

What happens if you have 2 cameras on one chip, and nothing on the other 3?

I'm using about 60MB of swap atop 6GB of physical RAM; free says 1.8GB or so available. And the other machine, alas, is having disk controller problems, and I haven't been able to get it to boot. That said, I would expect *less* trouble with the 32-bit install, since the binaries are half the size. ...

Here's a month's worth of tuning on this machine, which is still 12 720p Cams at 6fps modect; I upgraded the ffmpeg to: ffmpeg version 3.3.4-2~16.04.york0 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.4) 20160609 configuration: --prefix=/usr --extra-...

Ah, capture cards. I remember capture cards.

Could your frame rate be too high? It takes a finite amount of time for the video switch in front of the A/D converter to settle. You generally need an entire frame for each switch.

What frame rate are you recording at?

Check the filesystem permissions all the way along the path to

/usr/lib/zoneminder/cgi-bin/nph-zms

and make sure *the webserver owner user* has permission to search to there and execute. It sounds like your filesystem permissions have gotten ganked somewhere.

Jannnfe: "/zoneminder/" is an unusual thing to see in that pathname; it's customarily /zm/.

Did you pick /zoneminder/ in your install on purpose?

bbunge: this comes up *a lot*: do we have a poorly chosen default somewhere?

Optical focus?

No, I believe you'll have to do that with external code.
