surveillance cam : zoneminder and rasperry pi model b+

got a pi b+ model from straubson and installed: raspian jessy on it.

- add a file "ssh" in the /boot/ directory so you can access the pi without using a monitor, change the password afterwards.
Based on  https://bkjaya.wordpress.com/2016/11/23/how-to-install-zoneminder-1-29-0-on-raspberry-pi-3-with-raspbian-8-1-jessy-64-bit/  adapted it to work following these steps
-add zhe Jessie backports

sudo gedit  /etc/apt/sources.list

-add following line to the bottom of the file and save

deb http://http.debian.net/debian jessie-backports main

You will encounter signature errors, to
-fix those errors run following on the terminal

gpg --keyserver pgpkeys.mit.edu --recv-key  8B48AD6246925553
gpg -a --export 8B48AD6246925553 | sudo apt-key add -
gpg --keyserver pgpkeys.mit.edu --recv-key  7638D0442B90D010
gpg -a --export 7638D0442B90D010 | sudo apt-key add -

-Then run on the terminal

sudo apt-get update

-Install PHP, and MySQL server. You will be prompted to set a MySQL password

sudo apt-get install php5 mysql-server php-pear php5-mysql php5-gd

- Then install zoneminder using the software center of Raspbian

sudo apt-get install zoneminder

Create Zoneminder database in MySQL
There is a line missing from zm_create.sql that is packed with this version.
-If you search /usr/share/zoneminder/db/zm_create.sql (On Debian Wheezy, Your location may differ) for line:

CREATE TABLE `Logs` (

Simply add a line above this which reads:

DROP TABLE IF EXISTS `Logs`;

-Run following on the terminal

mysql -uroot -p < /usr/share/zoneminder/db/zm_create.sql
mysql -uroot -p -e "grant all on zm.*
to 'zmuser'@localhost identified by 'zmpass';"
mysqladmin -uroot -p reload
sudo chmod 740 /etc/zm/zm.conf
sudo chown root:www-data /etc/zm/zm.conf
sudo systemctl enable zoneminder.service
sudo adduser www-data video
sudo ln -s /etc/zm/apache.conf /etc/apache2/conf-enabled/zoneminder.conf
sudo a2enmod cgi
sudo a2enconf zoneminder
sudo a2enmod rewrite
sudo chown -R www-data:www-data /usr/share/zoneminder/
sudo systemctl enable zoneminder
sudo service zoneminder start

-Adding  timezone to PHP

sudo nano /etc/php5/apache2/php.ini

Edit 894 line to enter your time zone  and save the php.ini file
-then

sudo service apache2 reload

Open Zoneminder http://localhost/zm/

As USB Camera I used a 046d:08da Logitech, Inc. QuickCam Messanger (sic) according to lsusb

the resolution is bad, but, heck lets also account for annonymity

I set it up the following way

Monitor

If the USB camera on your pi tends to crash /stop working: set the resolution to 320 and 240

Zone Setting

Challenge: I want to count people using the biodegradbale bin . ( yep, nerdy...)

"The bin"

False events I get from

a) big cars/semis covering the bin

b) lights of cars passing by at night

Task

Set up zones

Zone 1 setting

zone 2 setting

zone 3

zone 4

and then I added as well a zone to overcome moving shadow induced by the trees/wind

  

Create a event video  every day

Since ffmpeg avconv etc and rasperry is not a love story, due to missing hardware accelerated video encoding of those packages use gstreamer - with that you use the very powerfull GPU, and it is actually converting the thousands of images to a vid faster than my WIN10 machine. Inspired , I managed to get the it run following this steps

sudo apt-get install gstreamer1.0-tools

sudo sh -c 'echo deb http://vontaene.de/raspbian-updates/ . main >> /etc/apt/sources.list'

add the missing key for this repo

gpg --recv-keys 0C667A3E
gpg -a --export 0C667A3E | sudo apt-key add -

 update your machine

sudo apt-get update
sudo apt-get -y upgrade

Install all necessary OPENMAX plugins for gstreamer

sudo apt-get install libgstreamer1.0-0 liborc-0.4-0 gir1.2-gst-plugins-base-1.0 gir1.2-gstreamer-1.0 gstreamer1.0-alsa gstreamer1.0-omx gstreamer1.0-plugins-bad gstreamer1.0-plugins-base gstreamer1.0-plugins-base-apps gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly gstreamer1.0-pulseaudio gstreamer1.0-tools gstreamer1.0-x libgstreamer-plugins-bad1.0-0 libgstreamer-plugins-base1.0-0

Create a bash script to create a movie out of daily images
and upload it to youtube based

install sudo apt-get python-pip 

based on on http://stackoverflow.com/questions/36962260/batch-upload-videos-to-youtube-via-command-line-python

#!/bin/bash
# Ugly script to generate AVI files for youtube  from zoneminder events

#cd $events_dir
# If you don't want the ENTIRE server's events and just want the latest week's worth
# then just add something like -mtime -7 before the "-print" part.  That's what I did later so I could have a weekly cron job.

exit

run the script as cron every nite

Mail events to Googledrive spreadsheet

install mail agent: http://www.sbprojects.com/projects/raspberrypi/exim4.php I prefer  exim4 with my gmail account, set gmail account to accept unsecure (sic) apps
since zoneminder EMAIL send is PITA
use https://ifttt.com/channels/google_drive/actions/81-add-row-to-spreadsheet

install

apt-get install html-xml-utils 

and add run with cron or a script for daily entries with a date and number events of the last 24


wget http://192.168.1.100/zm/index.php?view=events&page=1&filter[terms][0][attr]=DateTime&filter[terms][0][op]=%3E%3D&filter[terms][0][val]=-1+day&filter[terms][1][cnj]=and&filter[terms][1][attr]=MonitorId&filter[terms][1][op]=%3D&filter[terms][1][val]=1

and in case: the USB cam does suddenly stops working: unplug cam reboot device use a different port, etc see
https://www.raspberrypi.org/forums/viewtopic.php?t=17212

I have script which checks if the conenction zoneminder usb cam is broken, and reboots the pi, which usually brings the cam back on

#/bin/bash
echo Checking if USB Cam is still running.....
cd /home/pi/temp/

#extracting last 10min of syslog
sed -n "/^$(date --date='10 minutes ago' '+%b %_d %H:%M')/,\$p" /var/log/syslog
> last10min.txt

#if usb cam is not working..simply reboot.
if grep -q "Failed to start capture stream: Broken pipe" last10min.txt ; ##note
the space after the string you are searching for
then
echo "Cam not working" ; echo "restarted zoneminder due to broken pipe of USBCAM
" | mail -s "zm restarted" david.oesch@gmail.com ; sleep 10m ; rm last10min.txt
; /sbin/reboot
else
echo "Cam working"
fi

#if usb cam is not working..simply reboot.
if grep -q "Failed to set video format: Device or resource busy" last10min.txt ;
 ##note the space after the string you are searching for
then
echo "Cam not working" ; echo "restarted zoneminder due to Device busy" | mail -
s "zm restarted" david.oesch@gmail.com ; sleep 10m ; rm last10min.txt ; /sbin/re
boot
else
echo "Cam working"; rm last10min.txt
fi


exit

To omit zoneminder running at night I halt via sunwait command on bootup:

install

wget http://www.risacher.org/sunwait/sunwait-20041208.tar.gz

tar xvzf sunwait-20041208.tar.gz

cd sunwait-20041208/

ls

make

sudo cp sunwait /usr/local/bin

then launch it on boot



i) Create a script called mystartup.sh in /etc/init.d/ directory(login as root)

# vi /etc/init.d/mystartup.sh

ii) Add commands to this script one by one:

#!/bin/bash

/usr/local/bin/sunwait civ down -1:00:00 46.90860N 7.41549E; /usr/sbin/service zoneminder stop

iii) Setup executable permission on script:

# chmod +x /etc/init.d/mystartup.sh

iv)Make sure this script get executed every time Debian Linux system boot up/comes up:

# update-rc.d mystartup.sh defaults 100

Where,

mystartup.sh: Your startup script name

defaults : The argument ‘defaults’ refers to the default runlevels, which are 2 through 5.

100 : Number 100 means script will get executed before any script containing number 101. Just run the command ls –l /etc/rc3.d/ and you will see all script soft linked to /etc/init.d with numbers.

Next time you reboot the system, you custom command or script will get executed via mystartup.sh. You can add more commands to this file or even call other shell/perl scripts from this file too.

And of course I have at sixish in the morning a cron which starts up zoneminder

Upload Event Images

Download gdrive-linux-rpi and install it according to this guide 

Analogue above, create a script called zm_alatm which scans messages for alarmstates and add it to run update-rc.d


#!/bin/bash
tail -f /var/log/messages | grep --line-buffered 'Gone into alarm state' | while read line; do cp -p "`find /var/cache/zoneminder/events/1/$(date +"%y/%m/%d/") -name "*aptur*" -printf "%p\n" | sort -rn | head -n 1`" /home/pi/eventimages/$(date +"%Y%m%d%H%M").jpg;  done

the Result? Here


UPDATE: 2018

with "stretch" if followed this https://wiki.zoneminder.com/Raspbian
- just install php (not php5)
- for raspberry pi camera modul follow http://marcel.duketown.com/?p=651
