Re: How to create image of ZM computer?

@bbunge I knew I could count on someone to sneer :) Note that the OP was asking to back up the whole system, OS and all, not just the ZM database. It's no good having the full ZM database and blank hard drive. There could be a lot of configuring and installing to do before you get to restore the ZM ...

Re: How to create image of ZM computer?

This is one of the better cases for using partitions. Some people will sneer that it's "old school", and everything should just go in one big partition :) My ZM-running system is split between 3 partitions. 1) Tiny non-encrypted "boot" partition, 2) encrypted system partition, 3) encrypted data part...

Re: ZoneMinder and CIFS

There is no guarantee the writer of the SMB server has correctly implemented the boring bits. "It reads, it writes, something about permissions, yeah, ship it. No one uses symlinks." You can test it outside of zoneminder. Create yourself a directory on the external drive, where you have permission t...

Re: Image interference causes continuous recordings

Search the forum for "ffmpeg" and "streaking" and see what comes up, this happens on some systems.

Re: Continuous Recording - Double recordings

It's not duplicate data, if you look closely they are symbolic links. "Patio" and "Yard" are user-friendly names (links), where 1 and 10 are the camera IDs (the real directories) Don't worry about it :) /home/zonemind/events# ls -la drwxr-xr-x 3 apache apache 4096 Jan 8 2018 4/ drwxr-xr-x 3 apache a...

Re: can't use webcam with apps while zoneminder is running

I would expect not: If ZM is holding /dev/video0 open, it is using it. How do you think your webcam would cope with being told to use one resolution/frame rate by ZM, but another by Skype etc? It wouldn't work out well. This used to be the case with /dev/audio and /dev/dsp on the old days of OSS, un...

Re: Is it possible to blank a part?

I don't think such a facility exists in ZM -- you could write and add one, or possibly do something clever with FFMPEG Check out using FFMPEG video filters, option -vf and possibly the section in the manual on "overlay", and overlay your "black shape" from a .PNG file onto the video stream when you ...

Yet another one -- they are coming thick and fast lately :) "Can't symlink .... Operation not supported." The error message should have said "Your file system for events seems to suck. Please use a fully featured file system, written with real users in mind, not some poor quality Windows junk." Seri...

Re: ZM writes empty events folders to SMB share

Agreed. :(

Either there should be a massive warning on ZoneMinder's documentation: "Do not use half-baked file systems", or ZM should pro-actively test what kind of filesystem you are using and send you a clear message, saying "This is never going to work" :)

Re: ZM and Ubuntu 18.04: External Hard Drive Folder can't be accessed after time

"ls: reading directory '.': Input/output error" Never mind the usual caution to avoid NTFS/DOS/FAT partitions (as they don't work for ZoneMinder -- they don't support symbolic links), I worry about the hardware you are using given the error you quote. The upgrade to Ubuntu may be a coincidence. Plea...

Re: ZM writes empty events folders to SMB share

@bbunge it's not necessarily an actual NAS -- note the OP says "running in a virtual machine" and "save on a drive on the server ..." which could be the same machine, just outside the VM's little 20GB play-pen :)

Re: ZM writes empty events folders to SMB share

What is the file system type on this "SMB Share" -- if it's FAT (DOS-Windows) based then it will not work, as it does not understand symbolic links as used by ZoneMinder -- you need a proper file system (ext2/3/4) that has all the Unixy features. Also permission can be a pain on some SMB/FAT style s...

Re: How to delete many events quickly?

ZM Audit has never (as far as I know) left behind a load of entries when the files are gone. More likely it enthusiastically wipes database entries at the first sign the files are missing! Maybe others could suggest how to give ZM audit a kick to do the right thing, if the files have gone -- I'm not...
