ZM dropping cameras

Post by empty01 » Wed Apr 10, 2019 5:25 pm

Hi
I installed zm1.32 on a Sunfire x2250 with a 8Tb new HDD, running Ubuntu 18.04.1 LTS.

I have 16 IP cameras connected and am able to view their RTSP streams using FFMPEG and TCP.

However, ZM consistently drops certain cameras and I can't get them back by restarting ZM (or indeed by restarting the Sunfire x2250).

The only way I can get them back is by restarting the cameras themselves.

So on all my cameras I have setup a daily reboot. On some cameras they will last for a few hours, up to 12 hours, but I will always lose their streams in ZM by 16 hours (most after 4 hours).

However, I can still view the camera streams via the cameras' web interfaces, and view the RTSP streams via VLC.

Can't make sense of this:
If it was a problem with the cameras then why can I still view the camera streams via the cameras' web interfaces, and view the RTSP streams via VLC?
If it was a problem with ZM, why doesn't restarting ZM, or indeed by restarting the Sunfire x2250, solve my problems?

Any help gratefully received.

All best

Mark

When I first started to get serious about using ZM I encountered a similar problem to yourself. In my setup I have a NVR which has the cameras attached via BMC cables. The NVR provides two streams for each camera, Hi-Res and Low-Res. My first installation of ZM was on a single server which had all of the streams (16 in total) configured. I would get a few hours from this setup before having to reboot my server, which as you've experienced is great as you could easily miss something from the cameras during the reboot.

I now have a 4 VM's running ZM in Multi Server mode. Three of the servers are dedicated to the Hi-Res streams and the forth server handles all of the Low-Res streams. So far so good, I've not had any issues with this setup and have been running this way for about 12 months now. The servers get a reboot every now and then when doing an update via yum.

So it maybe worth installing VMWare and splitting your server into a similar configuration as mine.

Regards,

Garry

Thanks Garry
Interesting idea - i'll look into it, although as I pointed out: "I can't get them back by restarting ZM (or indeed by restarting the Sunfire x2250)"

I have read quite a lot of forum posts related to this issue and one suggestion that comes up is tuning mysql. Now bizarrely, I have built some mysql databases by writing direct mysql code as part of my day job, but I can't make sense of any of the 'tuning' instructions.

In my experience, cameras dropping out appear to be brand dependent.

What brand of cameras do you have?

All the ones that drop out have 'Robox' written on them. But also, some Robox cameras never drop out

Without logs we can do nothing.

Your url to the camera doesn't have any username/password included. So it's probably a camera auth problem.

Re: ZM dropping cameras

Post by empty01 » Fri Sep 06, 2019 12:20 pm

Just an update to this thread. Zoneminder is still dropping cameras - as described above. The only (rather imperfect) solution I have found is to install python-onvif, see:
https://github.com/quatanium/python-onvif

The act of Initializing an ONVIFCamera instance seems to nudge my lost cameras back into action. Weirdly, I don't have to use python-onvif to restart the camera, or send any other onvif commands, just Initialize the instance.

Does this make any sense to any Zoneminder experts? Makes no sense to me.

Anyway, I will now try to write a python script to monitor if cameras are 'not running' or 'not capturing'. Not sure the best way to do this, other that use curl and the API. Any hints gratefully received.

All best

Mark
