Zoneminder Installation on Debian Wheezy with Logitech QuickCam Pro 5000

Turning a £7 worth webcam into a simple home surveilance system.

Install Zoneminder

We’ll be using a 32bit Debian Wheezy VM:

$ uname -rv
3.2.0-4-686-pae #1 SMP Debian 3.2.51-1

Update the system and install Zoneminder:

# apt-get update && apt-get upgrade -uV
# apt-get install zoneminder

Install Apache web server:

# apt-get install apache2

Add Apache User to the Video Group

This is needed for the webserver to be able to access the webcam:

# ls -l /dev/video0
crw-rw---T 1 root video 81, 0 Dec 19 20:36 /dev/video0

Add user to supplementary group:

# usermod -aG video www-data

Link Apache to Zoneminder


# vim /etc/zm/apache.conf

Check the file to look as below:

Alias /zm /usr/share/zoneminder
ScriptAlias /cgi-bin /usr/share/zoneminder/cgi-bin
<Directory /usr/share/zoneminder>
php_flag register_globals off
Options FollowSymLinks
<IfModule mod_dir.c>
DirectoryIndex index.php

Link Apache file:

# ln -s /etc/zm/apache.conf /etc/apache2/conf.d/zoneminder.conf

Optional: Install Cambozola Java Plugin

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

# cd /usr/src
# wget
# tar xzvf cambozola-latest.tar.gz
# cp ./cambozola-0.935/dist/cambozola.jar /usr/share/zoneminder

Set Shared Memory Configuration

We’ve only got 1 GB or RAM installed on our machine:

# cat /proc/meminfo | grep -i memtotal
MemTotal: 1022744 kB

Therefore we’ll set the SHMMAX to not exceed a half or our physical memory, 512MB. SHMMAX is the maximum size of a single shared memory segment set in bytes. To change the value on a running system:

# echo 536870912 > /proc/sys/kernel/shmmax

To make a change permanent:

# echo "kernel.shmmax = 536870912" >> /etc/sysctl.conf

SHMALL is not causing any problems, therefore won’t be changed:

# cat /proc/sys/kernel/shmall

Restart Daemons

# service apache2 restart
# service zoneminder restart

Add WebCam to Zoneminder WebUI

Navigate a web browser to http://localhost/zm.

Click “Add New Monitor”. Settings for Logitech QuickCam Pro 5000 are shown below.



Under “System” tab, tick the box for “Authenticate user logins to ZoneMinder” to enable creation of user accounts with varying sets of permissions.

Under “Images” tab, check “Is the (optional) cambozola java streaming client installed” if chose to install earlier. Path to cambozola java streaming client should be “cambozola.jar”.

Under “Images” tab, add /usr/bin/ffmpeg to “Path to (optional) ffmpeg mpeg encoder (?)”.


# tail /var/log/messages
# tail /var/log/syslog

Also check Log section on Zoneminder WebUI.

Some Fixes

I’ve noticed that syslog is being spammed with the following:

ERR [Shared data size conflict in shared_data for monitor L5000, expected 328, got 316]

Easy fix is available here. Open /usr/share/perl5/ZoneMinder/ and change the following:

#our $arch = int(3.2*length(~0));
our $arch = 32;

Another one:

ERR [Can't make events/1: Permission denied]

And the fix:

# chown -R www-data:www-data /var/cache/zoneminder/events
# chown -R www-data:www-data /var/cache/zoneminder/images

  1. I enjoyed reading you research above. If you elaborate on this at some point would you consider developing for Mint?


    • Hi Paul. I’m glad you found it enjoyable to read.

      However, I’m not sure I understand your meaning regards further elaboration and development for Mint. You may want to be a bit more specific.

  2. I guess he meant you could do something (tutorial or even a porting) focused on Linux Mint Distro.

    • I don’t use Linux Mint myself, but as far as I’m aware, Linux Mint is based on Debian and Ubuntu. Therefore I don’t see why this article would not fit for any Debian based distribution, including Linux Mint.

    • Yep agreed… as I don´t use either I really dont know… anyway, nice tutorial tho.. Thanks for it.
