A Python Zone Sentry Program

Introduction

This post presents ZoneSentry.py. As the name implies it is a sentry application that uses a Passive Infrared (PIR) sensor in the same manner as the PIRLEDeMail.py program does. ZoneSentry.py is a total rewrite and renders PIRLEDeMail.py obsolete.

Attaching a Samba Share at Startup / fstab

Working through the efforts to install my Raspberry Pi (RPi) with camera and  pi-timolo, I ran across a problem getting attached to the SAMBA share on the PiNAS, before the application starts up and then tries to send pictures to the share.  Remember that the base instructions show how to set the program to start on boot (  init.d & update-rc.d setup ), but I was finding I had a failure to write due to the fact that the NAS share was not in my mounted devices list.

PIR Based Raspberry Pi Camera and Programming

One of our group is a very experienced programmer, (we have all programmed to an extent) and has come to love the Raspberry Pi (RPi) along with the rest of us.  Although his first taste of python was not well received, he has become somewhat of a fan (well that might be stretching it).  In his endeavor to reach new levels of programming proficiency as well as become more familiar with the hardware aspects of the RPi, he chose to write from scratch a program to automate the use of a PiCamera, along with accessing the GPIO ports of the RPi.  While he was at it he chose to add an LED indicator to show when movement was detected.

Pi, Cameras, Security, and NAS

We have been busy with many projects in our group, but have not posted or documented much.  This blog entry will attempt to be a recap of the e-mail discussions and the final setups we chose, your mileage may vary!

We have taken several approaches to utilization of cameras within our environment.

pi-timolo

The first approach used was one from Claude Pageau who documented his environment so well that it is simple to say – “just do it” based on his GitHub.com readme!  See the references page for the link.

A Python sensor program for Raspberry Pi

Introduction

This page presents a Python program that is designed to be a proximity sensor operating on a local network using WIFI. This sensor employs a Passive Infrared sensor (PIR), an LED to give a visual indication that movement has been detected by the PIR, a Picamera and the program presented here.

When the program, PIRLEDeMail.py detects movement, it will turn on the green LED, take a photo using the camera and then send an email with the jpg file attached to the intended recipient.
