Re: Crazy intermittent streaking issue on SV3C cameras

For me, this has resolved itself. I noticed that Centos updates recently included ffmpeg updates so I disabled my cron job to restart the Zoneminder service every hour and for the last month or so this issue has not returned. Fingers crossed it is now not going to happen again. My version of ffmpeg ...

Re: Crazy intermittent streaking issue on SV3C cameras

As reported previously I have this issue. It is on this model of camera: SV-B01-1080P-POE. I have upgraded on Centos (7) to Zoneminder 1.32.2 and still experience the issue. I currently have the system set to force a restart of Zoneminder every hour to limit the length of time it causes an issue. On...

Re: Only one camera will run

This is on Centos 7. The two directories were clearly there before I upgraded - they both contain files from Sep 8 and Oct 24 (I think Oct 24 is probably the date I upgraded Zoneminder). But they are all small files. I stand to be corrected, but I don't believe I caused these directories to appear h...

Re: Only one camera will run

Thanks - it is. 100% used. I've never had this before, so not sure how I should resolve it. Also, has something changed with the new release to cause this? This is the contents of /dev/shm: -rw------- 1 apache apache 311046160 Oct 25 20:00 zm.mmap.2 -rw------- 1 apache apache 311046160 Oct 25 20:46 ...

Only one camera will run

I've upgraded from 1.30 to 1.32 on Centos 7. Upgraded the database. Now only one of the two cameras will run at a time. When I restarted ZM, the first camera was capturing and the second was "not running". Everything looked OK and it was enabled. When I stop the first camera (un tick enabled against...

Re: Crazy intermittent streaking issue on SV3C cameras

Since setting up a cron job to restart Zoneminder once per day I've not (yet) seen any evidence of the problem - at most I'll get one day before the issue occurs. I am wondering whether it actually won't occur in that duration so will never see it again. It's not ideal in that it shouldn't need to b...

Re: Crazy intermittent streaking issue on SV3C cameras

I had a look at the log within Zoneminder and after the streaking starts there are lots of warnings like this: Buffer overrun at index 8, image 281408, slow down capture, speed up analysis or increase ring buffer size. Then I looked directly at the logging on the machine. Prior to the issue there ar...

Re: Crazy intermittent streaking issue on SV3C cameras

I had thought about adding a cron job to restart Zoneminder.

Yesterday I tried changing the source type to Libvlc - today it is already streaking so that didn't cure it.

Re: Crazy intermittent streaking issue on SV3C cameras

I have the same on Centos with a SV3C HD camera. I changed to 32 bit colour but that didn't solve it. In Centos 7, this is my ffmpeg: ffmpeg version 2.8.13 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-16) The main settings are below. If I try chang...

How to avoid recording snow and rain?

I've been tweaking my filtering and size settings and have managed to reduce many false triggers. But Zoneminder is still recording rain and snow. Typically these only have one or two alarm frames in a recording while a genuine recording of someone moving through the trigger zone has at least ten. U...

Lots of events with blue images when camera turned off

I have installed ZM 1.30.4 and added one wired camera. It works fine when the camera is powered, correctly capturing events when motion is present. When I turned the camera off before the PC (it's not yet permanently installed - just testing it prior to that) I found that lots of events are recorded...

Setting up disks

I am thinking of setting up CCTV and would intend to use Zoneminder. I also want to setup a back server (solely to backup files from my main server and laptops). Given that the load on the backup server would be low (probably timed overnight backups from my main file server and occasional backups fr...
