#KERBEROS.IO
As burgalary is very common, we believe that video surveillance is a trivial tool in our daily lifes which helps us to feel a little bit more secure. Responding to this need, a lot of companies have started developing their own video surveillance software in the past few years.
Nowadays we have a myriad of expensive camera's, recorders and software solutions which are mainly outdated and difficult to install and use. Kerberos.io's goal is to solve these problems and to provide every human being in this world to have its own ecological, affordable, easy-to-use and innovative surveillance solution.
Kerberos.io is a low-budget video surveillance solution, that uses computer vision algorithms to detect changes, and that can trigger other devices. Kerberos.io is open source so everyone can customize the source code to its needs and share it with the community. When deployed on the Raspberry Pi, it has a green footprint and it's easy to install; you only need to transfer the Kerberos.io OS (KIOS) to your SD card and that's it.
Use your mobile phone, tablet or PC to keep an eye on your property. View the images taken by Kerberos.io with our responsive and user-friendly web interface. Look at the dashboard to get a graphical overview of the past days. Multiple Kerberos.io instances can be installed and can be viewed with only 1 web interface.
The web is responsible for the visualization. It's a GUI which helps the user to find activity at a specific period, configure the machinery, view a live stream, see system information and much more. It's important to note that the machinery can work without the web, however we don't recommend this.
The web is written in PHP using the extremely popular PHP Framework Laravel, and Javascript using the client-side framework BackboneJS; to create the dynamic behaviour. We will discuss the different pages and functionality briefly. Please check out the demo environment if you want to see a real life example.
The reason why you're reading this paragraph is because you want to know how to install the web on your Raspberry Pi, local working station, server or whatever machine you prefer. The good news is that we have different approaches from basic to advanced; it depends on how you want to install it.
###KiOS (for Raspberry Pi)
KiOS is a custom linux OS (created by buildroot) which runs Kerberos.io out-of-the- (it contains both the machinery and the web). KiOS is installed like every other OS for the Raspberry Pi, you need to flash the OS (.img) to a SD card, update your network configration and you're up and running; no manual compilation or horrible configurations. This is the most simple and basic installation procedure.
###Raspbian (for Raspberry Pi)
If you already have a Raspberry Pi running with Raspbian, you probably don't want to reflash your SD-card. Therefore you can install the different parts of Kerberos.io (the machinery and the web) manual.
###Advanced
If you want to install the web, you'll need to have a webserver (e.g. nginx) and PHP running with some extensions. You also need nodejs and npm installed to install bower. Below you can find the installation procedure to install the web on the Ubuntu OS; the process is similar for another Linux OS.
Update the packages and kernel.
sudo apt-get update && sudo apt-get upgrade
Install git, nginx, php (+extension) and nodejs.
curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install git nginx php5-cli php5-fpm php5-gd php5-mcrypt php5-curl nodejs
Creating a nginx config.
sudo rm -f /etc/nginx/sites-enabled/default
sudo nano /etc/nginx/sites-enabled/default
Copy and paste following config file; this file tells nginx where the web will be installed and that it requires PHP.
server
{
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/web/public;
index index.html index.htm index.nginx-debian.html;
server_name kerberos.rpi kerberos.rpi;
index index.php index.html index.htm;
location /
{
autoindex on;
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$
{
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
Create a www location.
mkdir -p /var/www
Get the source code from Github.
cd /var/www && sudo git clone https://github.com/kerberos-io/web && cd web
Install PHP packages by using composer.
curl -sS https://getcomposer.org/installer | sudo php
sudo mv composer.phar /usr/bin/composer
sudo composer install
Change write permission on the storage directory.
sudo chmod -R 777 app/storage
Install bower globally by using node package manager, this is installed when installing nodejs.
sudo apt-get install npm
sudo ln -s /usr/bin/nodejs /usr/bin/node
sudo npm -g install bower
Install Front-end dependencies with bower
cd public
sudo bower --allow-root install
Restart nginx
sudo service nginx restart
You can access the web by entering the IP-address in your favorite browser. You'll see a login page showing up, on which you will need to enter your credentials. The default username and password is root. You are able to change this password by editing the app/config/app.php file.
