Monitor Camera and Relay Control Over Internet

Many of us have smartphones, iPads or netbooks that we take with us and it would be great to check in on the place, in a coffee shop or while traveling. Now we use the raspberry pi 2 for monitoring camera and control relay over internet. Everything is explain for the 11 step.

In addition to basic relay control you have many configuration options. For example, you can configure the units to close the contacts for a preset time and then open again, or toggle the relays whenever a voltage is applied or you can even write a custom script to close the relay five times in a certain sequence.

Step 1: Basic Equiment

1. Raspberry Pi 2 + Case

2. Micro Usb Charger 5V

3. Mouse and Keyboard

4. Cable and Screwdriver

5. Relay Module

6. 2 pcs Usb Camera

7. Micro SD card 8Gb

8. LCD monitor, Driver, HDMI cable and Power Supply 12v

Step 2: SD Card Setup With Windows XP

Download your preferred Operating System (OS) you wish to run from the Raspberry Pi website: https://www.raspberrypi.org/downloads/raspbian/
You will need to use a program such as Win32DiskImager (search from google). This program will write the image structure required for the Raspberry Pi to boot from the SD card.
Open Win32DiskImager, Load image file “Raspbian” OS to your SD card device, then click write
Eject SD card, insert to your Raspberry Pi 2

Step 3: Resize Partitions

Insert SD card to your Raspberry Pi 2, power up and wait until display the raspberry pi software configuration tool (raspi-config)
Choose number 1 ( Expand Filesystem ), press enter, then choose finish, raspberry will reboot

Step 4: First Boot

Login your raspberry pi 2
- Raspberrypi login : pi
- Password : raspberry
Write “startx” and press enter

Step 5: Remove Border on Your Display Lcd ( If Not Full Screen )

Find and open LXTerminal write “sudo nano /boot/config.txt”
Uncomment ( Remove # ) disable_overscan=1
Uncomment ( Remove # ) the following to adjust overscan, change to zero
Press Ctrl-X, write “Y” and press enter to change the config.txt
Write “sudo reboot”
Wait and the border will remove

Step 6: Solving Error “GDBus.Error.org.freedesktop.PolicyKit1.Error.Failed . . . “

Open LXTerminal, type lxsession-edit to open Desktop Session Setting
Uncheck LXPolKit
Reboot your Raspberry Pi 2

Step 7: Install Motion on Raspberry Pi 2

Open LXTerminal and write
- sudo apt-get update
- sudo apt-get upgrade
- sudo apt-get install motion
Enable motion daemon
- sudo nano /etc/default/motion
  - change line to start_motion_daemon=yes
  - Ctrl-X, save modified buffer Y, and press enter
Motion configuration
- sudo nano /etc/motion/motion.conf
  - daemon = OFF to ON
  - webcam_localhost = ON to OFF
Check usb camera
- Plug your 2 usb camera to your raspberry pi 2
- Check on LXTerminal
  - ls /dev/vid*
Start / Stop Motion
- sudo service motion start
- sudo service motion stop
Test your usb camera
- Make new folder “camera” on home/pi/camera
- Go to LXTerminal write “cd camera”
  - write “sudo nano cam1.conf”
    - videodevice /dev/video0
    - webcam_port 8081
  - write “sudo nano cam2.conf”
    - videodevice /dev/video1
    - webcam_port 8082
- add following line to /etc/motion/motion.conf
  - thread /home/pi/camera/cam1.conf
  - thread /home/pi/camera/cam2.conf
- Check your Dynamic IP using LXTerminal
  - Write “ifconf”, use the inet addr
  - Remember to restart motion “sudo service motion restart”
  - Test on your browser http://192.168.1.122:8081/ and http://192.168.1.122:8081/

Step 8: Download and Install Last Release Webiopi

Download file webiopi on http://webiopi.trouch.com/DOWNLOADS.html and adapt x.y.z with the version you download. Put the file to /home/pi
Open LXTerminal and write the step
- $tar xvzf WebIOPi-x.y.z.tar.gz
- $cd WebIOPi-x.y.z
For only Raspberry pi 2, must change the following step
- Python/native/cpuinfo.c change 'BCM2708' to 'BCM2709'
- Python/native/gpio.c '#define BCM2708_PERI_BASE 0x20000000' to '#define BCM2708_PERI_BASE 0x3f000000'
Then install webiopi
- $sudo ./setup.sh
- Setup may take a moment
Run your webiopi
- $sudo webiopi -d-c /etc/webiopi/config
- You are done, and ready to enjoy WebIOPi! But the server and GPIO state will be lost when you'll stop the script (CTRL-C) or close the terminal
Start/Stop WebIOPi
- $sudo /etc/init.d/webiopi start
- $sudo /etc/init.d/webiopi stop
Access WebIOPi over local nettwork
- If your Raspberry Pi is connected to your network, you can open a browser to http://raspberrypi:8000/ with any device of your network. Replace raspberrypi by its IP
- Default user is 'webiopi' and password is 'raspberry'
Begin the script
- Create a folder somewhere on your P, for instance /home/pi/myproject. This is main folder
- Create another python folder in the previously created. I will store Python script file here
- Create another html folder next to python. We will store HTML and other resources here
Configuration
- Edit /etc/webiopi/config
  - Script
    - myproject =/home/pi/myproject/python/script.py
  - Http
    - doc-root=/home/pi/myproject/html
- Remember to start your WebIOPi
  - $sudo /etc/init.d/webiopi start

Step 9: Python Script, Html File and Connection Raspberry Pi and Relay Module

Inside script.py file
- http://sourceforge.net/projects/script-py-file/files/script.py/download
inside html file
- http://sourceforge.net/projects/script-py-file/files/index.html/download
Connection Raspberry Pi and relay module
- Raspberry pi PIN 02 (DC 5v) to relay module (VCC)
- Raspberry pi PIN 06 (Ground) to relay module (GND)
- Raspberry pi PIN 03 (GPIO 02) to relay module (IN1)
- Raspberry pi PIN 05 (GPIO 03) to relay module (IN2)

Step 10: Test Connection Over 192.168.1.122:8000

There are two camera online at 192.168.1.122:8000, two relay that can be energize by press the button. User name is 'webiopi' password 'raspberry'
