I used a Pi Model A with a Raspberry Pi camera modified to remove the IR filter for this project, and a wifi usb dongle. I was not able to find an example on the net that gave me exactly what I wanted, so I decided I would post my work in case it would help someone else who wants to build a very simple motion detection system. I have been using a modified version of the ‘motion’ program that was customized for the pi, but I did not like how it worked, so why not try something else? The best performance is accomplished using c, however I ran into the picamera python library and decided that I wanted to give it a try since I needed to get more proficient at python code for work. Motion detection on the Pi is a very common task that many people have done on the net.
