Re: Firefox Extended Support Release

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).

Re: 3 * HikVision 4MP cameras taking too much CPU

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...

Re: HOWTO:Zoneminder recording if your 'iPhone' is out of home

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.

Re: Wansview IP Cams working nicely

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...

Re: Performance tuning time

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...

Re: lines on screen when second cam is added on channel

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?

Re: Performance tuning time

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-...

Re: lines on screen when second cam is added on channel

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?

Re: Camera shows no picture. Socket does not exist

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.

Re: Camera shows no picture. Socket does not exist

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

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

Re: Change focus on local (USB) camera

Optical focus?

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