+Raspberry Pi + Webcam + Zoneminder
+Submitted by bshea on Wed, 02/11/2015 - 12:07
+===0. Parts & Software===
+  * 1 - Raspberry Pi (RPi) with 512 MB + 32GB SD card. (Model = 0x0e / 2B) (SSH console only.)
+  * 1 - Microsoft LifeCam HD-3000
+  * Raspbian Linux (free)
+  * Zoneminder Security Camera Software (free)
+Approximate Total Price: ~$50
+Notes and Quirks with webcams:
+This webcam does not need a self-powered USB hub. Some models do.
+This model is not found using "zmu -d /dev/video0 -vqV2" (etc) - it does not enumerate. I used v2l utils to identify capabilities.
+You may want to consider running Zoneminder on a desktop/server machine and use Pi as capture only. I ran it all from Pi to show it can be done.
+===1. Install===
+Installing Zoneminder should also install (among others) php/mysql/ffmpeg and apache2 - I like to do Apache separately.
+   sudo apt-get update && sudo apt-get upgrade
+   sudo apt-get install apache2
+   sudo apt-get install zoneminder
+   sudo apt-get install v4l-utils
+Unfortunately the package for Zoneminder needs some work. Please follow this carefully!
+===2. Configure Apache/Web and Permissions===
+# Allow www-data to access webcam:
+   sudo usermod -aG video www-data
+# Add CGI ScriptAlias if not present after installing:
+   sudo nano /etc/zm/apache.conf
+   Alias /zm /usr/share/zoneminder
+   ScriptAlias /cgi-bin /usr/share/zoneminder/cgi-bin
+   <Directory /usr/share/zoneminder>
+    php_flag register_globals off
+    Options Indexes FollowSymLinks
+    <IfModule mod_dir.c>
+      DirectoryIndex index.php
+    </IfModule>
+   </Directory>
+# Correct ownership/give write+read+execute dir access to www-data group under /var/cache/zoneminder/*
+   sudo chown -R root:www-data /var/cache/zoneminder/*
+   sudo find /var/cache/zoneminder/ -type d -exec chmod 775 {} +
+# Correct Perl memory bug in zoneminder code if present:
+# REF : http://www.freshports.org/multimedia/zoneminder/files/extra-patch-scripts_ZoneMinder_lib_ZoneMinder_Memory.pm.in
+   sudo nano /usr/share/perl5/ZoneMinder/Memory.pm
+# line 130 - Change from:
+   '-our $arch = int(3.2*length(~0));
+# To:
+   '+our $arch = 32;
+# SymLink Apache file to conf.d:
+   sudo ln -s /etc/zm/apache.conf /etc/apache2/conf.d/zoneminder.conf
+# Install Cambozola Java Plugin
+   mkdir ~/tmp && cd ~/tmp
+   wget http://www.andywilcock.com/code/cambozola/cambozola-latest.tar.gz
+   tar xvf cambozola-latest.tar.gz
+   sudo cp ./cambozola-*/dist/cambozola.jar /usr/share/zoneminder
+   cd ~ && rm -rf ~/tmp
+===3. Find your webcam formats for zoneminder===
+# Find formats of webcam for zoneminder config:
+   zmu -d /dev/video0 -vqV2
+# If that does not work or fails to enumerate, try:
+   v4l2-ctl --list-formats
+===4. Kernel shared memory settings:===
+# Set shared memory for 512MB RPi board:
+# 128MB shhmax shared:
+   sudo su -
+   echo "kernel.shmmax = 134217728" >> /etc/sysctl.conf
+   exit
+# 2MB shmall pages:
+   sudo su -
+   echo "kernel.shmall = 2097152" >> /etc/sysctl.conf
+   exit
+===5. ZM Setup and Testing===
+REBOOT RPi & open a web browser pointing to local RPi IP
+From Pi desktop:
+   http://localhost/zm
+or
+   http://LAN.IP.FOR.RPI/zm
+if on separate pc on local network (Recommended)
+Note: Remeber that running a desktop manager under the RPi will use more memory and resources - not advised.
+Setup a bandwidth profile:
+Click Options on far right. Click "High B/W".
+Change "WEB_H_REFRESH_IMAGE" to "5" (seconds).
+Make sure "jpeg" is set as method for stream.
+SAVE.
+On main console page pick "Low" Bandwidth link and change to "High" Bandwidth.
+Misc Options to check or set (Optional)
+Click Options on far Right and Pick "Images"
+Look for OPT_CAMBOZOLA and check it.
+Look for PATH_CAMBOZOLA and you should see or set to: "cambozola.jar" (only)
+Look for PATH_FFMPEG and set to: "/usr/bin/ffmpeg"
+Note: For Cambozola to work, you may need to set an exception on it's Java jar. (Self-Signed as of this writing)
+SAVE.
+Video
+-> Select "/dev/video0 (0)" Link (or your default device)
+GENERAL TAB:
+Source: Local
+Function: Monitor (later you can change this if everything works to MoDetect)
+Set frame rate at 5. Set 10 as max.
+SOURCE TAB:
+(Setup web/security camera using settings found above in STEP 3).
+(Many cheaper webcams use NTSC or PAL + YUYV or MPEG1 compression)
+Channel = 0
+x240 -> (Set capture width @ 320 or less. Set capture height @ 240 or less.)
+SAVE.
+Test the Web Streaming
+Click 'Monitor-1" (default monitor) from main console page.
+You should see: a stream if using Cambozola, or a new JPG every 5 secs if not using it.
+Note on Cambozola: You may need to edit security for your Java client and add an exception for your IP address/site to avoid Java execution errors or warnings. (The Jar file is self-signed.)
+You should now have a basic working Zoneminder install on your Pi!
