Raspberry Pi as low-cost HD surveillance camera
A tutorial by Christoph Bünger, Director of Scavix Software Ltd. & Co. KG
Introduction
This article describes how to build a surveillance cam based on a Raspberry Pi micro-computer which records HD video when something moves in the
monitored area. Live picture can be viewed from any web browser, even from your mobile while you're on the road.
What you will get:
See live stream in any web browser from anywhere
Record any motion into video file
Usually, such a cam will cost you around US$1.000, but with the result from this article, you will get such a cam for only about US$120.
Hardware components
We need some hardware for this project. This is a list of the major things we need:
Raspberry Pi Model B: This is the larger model of the Raspberry computer system with 700MHz and 512MB Ram. It supports HD video. You can
easily order it from i.e. here. Cost: about US$40
You could also use the Raspberry Pi Model A which is slightly cheaper and consumes less energy. Stefan Knight has written an excellent article on
how to run this whole project on a model A. If you plan to use a model A, please read that article.
Raspberry Pi Camera Module: This module was specially build for the Raspberry micro-computer. It has a connector to be plugged directly into the
Raspberry board and supports HD video up to 1080p. The website http://www.rs-components.com/raspberrypi will show you where you could order it
from your country. I.e. http://www.alliedelec.com/lp/130513rasocameramodule/ ships this camera in the US for only US$29.
There will be an infrared camera module for the Raspberry Pi soon as well (http://www.raspberrypi.org/archives/5089). We've not yet had the chance
to test it, but it should work for this surveillance camera as well.
A housing for the camera: you don't need to buy a high-price-housing for your Raspberry. There are loads of very cheap fake security cameras
available which perfectly fit our needs here. Search the web for "surveillance camera dummy" and you will find loads of housings for your new camera
for only a few dollars. I.e. this one will do the job: http://amzn.to/15XLaAj for only US$9. We have ordered this camera housing for about 20€ in
Germany that had enough space for all the components: http://amzn.to/19CTEaN. You can use any camera housing, but only be careful about the size
of the housing so that the Rasperry board will fit in there. The dimensions of the Raspberry board are 85.6 x 53.98 x 17 mm (approx 3.37 x 2.13 x
0.67 in).
Power supply: The Raspberry computer does not come with any power supply, you have to get one on our own. Any power supply with a micro-USB
