Zoneminder Build Notes

Required for Building

  • MySQL www.lamphowto.com Notes on compiling MySQL from source
  • OpenSSL
  • PHP
  • Apache
  • Perl/Libperl

./configure will complain if anything is missing.

Installing from Source

./configure --with-mysql=/usr/local/mysql
--with-ffmpeg=/home/src/ffmpeg-0.4.9-pre1
--with-lame=/home/src/lame-3.96.1/libmp3lame
--with-webdir=/home/sites/Security.658Ridgecrest.com/web
--with-cgidir=/home/sites/Security.658Ridgecrest.com/web
--with-webuser=httpd
--with-webgroup=httpd
--with-libarch=lib
--enable-debug=yes

OR

./configure --with-webdir=/var/www/htdocs/ZM
--with-cgidir=/var/www/cgi-bin --sysconfdir=/etc
--with-webuser=httpd
--with-webgroup=httpd

OR

./configure --with-webdir=/var/www/html/zm
--with-cgidir=/var/www/cgi-bin ZM_DB_PASS=<password>

Create and Populate the Database

mysql mysql < db/zm_create.sql
mysql mysql
> grant select,insert,update,delete on <database name>.* to '<database user>'@localhost identified by '<database password>';
> quit
mysqladmin reload

Misc Notes (Anyone care to categorize?)

Check zone.conf or zm.conf. Check that there are no bogus vesions of this file lying around.
"nobody" doesn't have shell access, choose a different Apache alias like "httpd".
zmdc.log or /var/log/messages log any errors.
zm.sock file must be able to be created.

Apache

Permissions Problems

sudo -u apache /etc/rc.d/rc.zoneminder start

    • now.. zmc and zma is running on user apache

su Issue

Allowing CGI Execution (REQUIRED for ZM)

http://www.zoneminder.com/forums/viewtopic.php?t=5853

  • /usr/local/etc/zm.conf must exist and what process owns it.

webuser and webgroup must be correct for apache to have ownership over zm.conf

BIOS Issues

Turning off ACPI power management in the BIOS may help alleviate some issues with ZoneMinder and capture hardware.


Brightness control

Contribs Forum

The contribs forum contains contributions from ZoneMinder users like yourself!

Cambozola

Cambozola is a Java plugin that decodes multipart JPEG streams. Mozilla-based browser have native support, so this plugin is for browsers like Internet Explorer that lack that support.

To install Cambozola for use in zm, Download the cambozola.jar file from the Downloads page or directly from the charliemouse website. If you download from charliemouse you will need to extract the one file (cambozola.jar) from the archive. Place cambozola.jar in the ZM root web directory (so if your web pages for ZM is installed at /var/www/html/zm the file should go there as well). Now all thats left to be done is to enable it in ZM goto options and under the web tab check that cambozola is enabled. Thats it, you'r done.

Backup a Database

In Ubuntu and other modern distributions you can install MySQL administrator GUI.

the default login is :-

In here, there is backup and restore functions. The backup can also be scheduled.

ffmpeg

  • Install ffmpeg for Fedora with

yum -i ffmpeg
yum -i ffmpeg-devel

rpm -ivh http://rpm.livna.org/livna-release4.rpm yum install ffmpeg ffmpeg-devel Place the devel stuff in /usr/include/ffmpeg Now configure, make, make install

./configure , make, make install, make installibs

Increase Image size

If you increase the image size on a camera, it's always best to close down any streams and restart ZM to make sure that all memory is released. http://www.zoneminder.com/forums/viewtopic.php?t=7049

Image display problems

Also remember you may need to increase your 'shared memory'. See the FAQ for details

Kodicom Capture Cards

Edit your /etc/modprobe.conf file and add this line:
options bttv card=77

All screens must be the same resolution.

note that under ubuntu that the file to edit is /etc/modprobe.d/aliases.

Logitech USB QuickCam

  • I'm using FC4 and had a similiar problem with a quickcam 4000.

I guess you are using the default module supplied with CentOS. I think, not sure about this though, that it is missing some capabilities. So I installed the pwc module (http://www.saillard.org/linux/pwc/INSTALL.en) and these crashes stopped. http://www.zoneminder.com/forums/viewtopic.php?t=5906

Vehicle Detection Links

  • All things are possible and the example someone posted a while back of detecting trucks and buses, but not cars, passing over a distant intersection is probably appropriate for you. What I would suggest you need are quite high pixel differences (indicating difference from the background) and pretty small counts of changed pixels or blob sizes. You might find it useful to turn on diagnostic images initially (and only for a while as they slow everything down a lot) which will output what ZM thinks the differences etc are are in the images.

Zone Configurations and Fine Tunings

  • This section needs alot of work. Please contribute as much as you can!

Once you have Zoneminder up and running and all your cameras recording events, it then becomes important to fine tune your zones so that you record all of the events that are important to you, and just as important, NOT record events that are not important.

There are many parameters to be adjusted. So many, in fact, that it is easy to change just a few parameters, and create a config that does not do what you want at all. It is all so confusing. Here, we will attempt to document some basic configs, and explain in some detail the effects that each parameter will have and how each parameter relates to the other parameters.

The Documentation page offers some help in understanding how these parameters are related and important. You can view the online documentation here:
