The Concept

I have quite a large home built CCTV network at home recording to a very under-powered PC. This is mainly due to my passion for CCTV as a tech more than any real security concerns. I do have a rather large blind spot to the side of my house that I would really like to cover though. The system currently consists of a few dlink internal wifi cameras fitted externally (and surviving wonderfully!) and a dedicated external Foscam camera.

The Problem

CCTV cameras are relatively expensive and the blind spot really isn’t THAT much of an issue. Perhaps there is another solution.

The 3D printing work opened my eyes to the wonderful world of the Pi (raspberry!) as there is a rather excellent application called Octoprint that sits on a Pi and runs my printer remotely for me. It has a very nifty 3D printed case. I also have another Pi in the house that belongs to my daughter and runs the amazing RetroPie, this runs classic console games and is connected directly to my TV. It also sits in a 3D printed NES looking case. Can you guess where we are going here?

The solution

I intend to build a 3D printed security camera for as little outlay as possible and slave it to my network recorder.

The first steps here are to determine criteria.

1) Siting: The upstairs bedroom has a perfect view of my target. This is great because it means that I dont need to waterproof my system or run a cable externally.

2) Communications: I need to access the camera on my network so wifi or ethernet is a must. As it will be upstairs away from my router the only real option is wifi.

3) Size: small is desirable, we want to be discrete and I dont want it being in the way. it also needs to be tall enough to “peep” over the window frame.

So with that in mind my starting points are the Raspberry Pi Zero W and ZeroCam Fisheye module. Both purchased from PiHut in the UK.

Its now a case of waiting for them. My next steps will be

1) Testing of the software I intend to use in a barebones scenario.

2) Measuring the hardware

3) Designing the case.

Cost so far? about £25

Stay tuned for part 2.
