Raspberry Pi: Vocal Intruder Warning System Project @Raspberry_PI #piday #raspberrypi

Raspberry pi red

This raspberry Pi warning system tutorial shows you how to take snapshots of intruders using a raspberry pi camera board, from Vincent Willcox at class think.

I have recently purchased one of the fantastic Raspberry Pi Camera modules. The camera costs around £20 and plugs into one of the special sockets on the Raspberry Pi. This socket connects straight into the Graphics Card (GPU) so it has excellent response times.

To take advantage of the Raspberry Pi camera I have added some code to my original Vocal Intruder Warning System Project that will take a still image each time somebody moves past the PIR sensor…

For this project I will assume you have already followed the original vocal intruder project, so will only cover the extra setup required to get the camera working in the project.

What you will require:

  • Raspberry Pi Camera Module
  • Raspberry Pi
  • A Speaker
  • A PIR Module
  • Three connecting wires (female to female – like this bundle from ModMyPi)
  • An internet connection (Wireless or wired is fine – if you can’t provide internet access to Google then you will need to use an offline Text To Speech module).

Getting Started

For this project I will assume you have already followed the original vocal intruder project, so will only cover the extra setup required to get the camera working in the project.

First ensure your camera is connected as per the official instructions and video.

Adding the new Python librarys

On the Raspberry Pi, either via SSH or directly connected, enter the following commands:

sudo apt-get install python-picamera
When the module has finished installing then make a copy of your original code:

  1. It’s nice to see my posts getting some attention!
    Thanks Adafruit for posting 🙂

    Just thought I would let you know I have two more features going that will be added to this project tonight.

    1) SMTP Email of the photo and video
    2) Notify my Android support
