DIY Home Security System using Raspberry Pi<\/p>\n

The Raspberry Pi computer is being used in many projects around the world. Inexpensive, small and powerful, this credit card size computer enables you to implement cool products.<\/p>\n

If you also bring your kids into this equation, the project will have a childish sparkle. Doing projects with my son is fun and allows him to learn about software, electronics, prototyping and building a product that solves a real need.<\/p>\n

This tutorial will guide you step by step to build a Home Security System using Raspberry Pi. The security device will be connected to the main entrance with a magnetic door sensor. When the door opens, the sensor triggers an event on the Raspberry Pi. The device takes pictures and sends you an email alert.<\/p>\n

DIY Home Security System\u00a0– Parts list<\/h2>\n

In this step, we will look at the parts needed for the security device. I have created a list \u00a0with all the parts. This is just a guideline, you can find all these products on other websites. Also if you have extra time you can probably find better deals or faster shipping times.<\/p>\n

DIY Home Security System – Hardware assembling<\/h2>\n

In this step we will prepare the hardware at the prototype level. A few wire cutting and soldering is required. \u00a0At the end when we have validated the working prototype we will assemble the final product.<\/p>\n

Prepare the wires, solder the resistor on one wire (be sure you add the shrink tube\u00a0before soldering. The long wire connected to the door should be measured to cover the distance from door to the device.<\/p>\n

<\/p>\n

DIY Home Security System – Software Configuration<\/h2>\n

In this step we will install the OS (Operating System) on the SD card.<\/p>\n

Download latest Raspbian OS from Raspberry Pi Download Page<\/a><\/p>\n

Install Raspian OS on the SD card following the instruction at \u00a0INSTALLING OPERATING SYSTEM IMAGES<\/a><\/p>\n

After installing the OS on the SD card, you are ready to start your Raspberry Pi.<\/p>\n

Connect the Raspberry Pi to the network router using a network cable. <\/strong><\/p>\n

For the next step you have two options: 1. connect the raspberry pi to a monitor and keyboard or 2. connect to raspberry pi using ssh from another computer (in case 2 \u00a0you don’t need monitor and keyboard)<\/p>\n

Scenario 1 – Connect Raspberry Pi using a TV\/Monitor and keyboard<\/h2>\n

Use a HDMI cable to connect the Raspberry Pi to a TV or to a monitor that supports HDMI. Connect the keyboard to one of the USB ports.<\/p>\n

Plug the power cable on the Raspberry Pi (the micro usb connector).<\/p>\n

Login with user pi, password raspberry<\/p>\n

Continue with “Install Wifi configuration tools”<\/p>\n

Scenario 2 – Connect to Raspberry Pi using SSH from another computer<\/h2>\n

If you don’t have a TV or Monitor that supports HDMI, you can\u00a0connect directly from another computer using SSH.<\/p>\n

First step is to detect what IP was assigned to your Raspberry Pi.<\/p>\n

Using a browser connect to your Router [e.g. http:\/\/192.168.1.1<\/a>]. After you login with your router credentials, browse the list of connected devices (each router has a different page for this feature). Because your device is currently connected with a network cable, you should look at that section.<\/p>\n

You can also consult he detailed documentation how to detect your Raspberry Pi IP<\/a><\/p>\n

After you have the Raspberry Pi computer IP, from your machine run ssh to connect remotely. [Note: if you are on a Mac or Linux, the ssh is already installed, on Windows you have to manually install ssh, see documentation how to install ssh on windows<\/a>]<\/p>\n

Run the SSH tool [putty.exe for windows or ssh command in a terminal for Mac] and login with username pi, password raspberry.<\/p>\n

Install Wifi configuration tools<\/h2>\n

run the update for the OS:<\/p>\n

sudo apt-get update<\/code><\/pre>\n
install a command line tool to configure the WIFI:<\/p>\n
sudo apt-get install wicd-curses<\/code><\/pre>\n
run the wifi tool<\/p>\n
sudo wicd-curses<\/code><\/pre>\n
\"Home<\/a>
Home Security Device – wifi config tool<\/p><\/div>\n
Using arrows keys, select your Wifi Network and press right arrow key to edit its properties. Type your wifi password in the Key section. Also check the “Automatically connect to this network” checkbox. Press F10 to save.<\/p>\n
\"Home<\/a>
Home Security Device – wifi config<\/p><\/div>\n
In the first screen (the list of networks) if you connect to the wifi (capital C) then you will be disconnected from the wired connection and the current ssh session. What I suggest is to exit (capital Q) and reboot the Raspberry Pi: “sudo reboot” and disconnect the network cable.<\/p>\n
After 2-3 minutes, check again your router to find the new IP of you Raspberry Pi (now a wifi) and connect using SSH to the new ip.<\/p>\n

<\/p>\n
DIY Home Security System – Install and configure the door sensors application<\/h2>\n
In this step we look at the door-sensor <\/a>software.<\/p>\n
All the commands on this page are executed on the raspberry pi box. See previous page for tips to connect remotely using ssh.<\/p>\n
In order to run java programs install the JDK<\/p>\n
First, check if you have java pre-installed<\/p>\n
java -version<\/pre>\n
my current output is<\/p>\n
java version \"1.8.0\"\r\nJava(TM) SE Runtime Environment (build 1.8.0-b132)\r\nJava HotSpot(TM) Client VM (build 25.0-b70, mixed mode)<\/span><\/pre>\n
If you get an error or you have an older version of java, install the java 8 JDK:<\/p>\n
sudo apt-get install oracle-java8-jdk<\/span><\/pre>\n
Re-run the java -version command to verify the installation.<\/p>\n
Download the doorsensors build<\/p>\n
cd ~\r\nwget http:\/\/teakdata.com\/doorsensor\/doorsensor-1.0.0-SNAPSHOT-bin.zip<\/span><\/pre>\n
Unzip the package<\/p>\n
unzip doorsensor-1.0.0-SNAPSHOT-bin.zip<\/span><\/pre>\n
At this point you should see the folder doorsensor-1.0.0-SNAPSHOT<\/p>\n
ls doorsensor-1.0.0-SNAPSHOT<\/pre>\n
The above command should list all the files in the new folder:<\/p>\n
door.properties\u00a0 <\/span><\/span>door.sh<\/b><\/span>\u00a0 <\/span><\/span>lib<\/b><\/span><\/em><\/pre>\n
Edit the configuration file door.properties, I am using the nano editor. After finished your changes, to save press CTRL-o and press enter to save to existing file. To exit press CTRL-x<\/p>\n
cd ~\/doorsensor-1.0.0-SNAPSHOT\r\nnano door.properties<\/pre>\n
The main changes you should do in the door.properties file are related to your email configuration.<\/p>\n
IMPORTANT: it is a good idea to not use your main email, you can create a test gmail account to use it with the device. As “email.to” you can use your real email to receive notifications.<\/p>\n
The sample has preconfigured values for GMAIL accounts (smtp host, port).<\/p>\n
#destination email to send the pictures\r\nemail.to=your_real_email@gmail.com\r\n#sender email\r\nemail.from=your_test_email@gmail.com\r\n#smtp server configuration\r\nemail.smtp.host=smtp.gmail.com\r\nemail.smtp.port=587\r\nemail.smtp.user=your_test_email\r\nemail.smtp.passwd=yourpassword<\/pre>\n
We are now ready to start the application.<\/p>\n
cd ~\/doorsensor-1.0.0-SNAPSHOT\r\nsudo .\/door.sh<\/pre>\n
The application is running and the logs are now displayed on the console. To close the application use CTRL-C<\/p>\n

DIY Home Security System – Final Assembly<\/h2>\n
At this stage we have all the parts assembled and the software running.<\/p>\n
Now we need to wrap everything nicely and place the device in a spot where it can view the monitored entrance.<\/p>\n
