Reverse engineering a home security system

Ken from OverEngineered writes us about his recent efforts in reverse engineering,

I recently reverse-engineered the security system installed in my house and re-implemented the control board for it using a JeeNode (arduino-compatible with on-board RFM12 radio).

I created a post about the reverse-engineering here.

And another post about a demo of the wireless Security Node with host interface UI. The code and schematics are posted on my GitHub page.

  1. I have a feeling this was a much older generation alarm system to the ones that are currently available on the market. Most commercial home alarm systems these days are properly obfuscated to avoid people hacking them and ultimately bypassing them. Many even have encryption and proprietory chips that you really can’t copy with something like Arduino.

    For example, check out some of the digital home security systems offered by the likes of Yale at the moment… some of the more comprehensive systems are more than just a digital interface for the traditional analogue signals; they actually rely on the the central controller to designate and control zones.

    I really like what Ken managed to achieve here, but what I’m saying is that I don’t think it undermines the state of home security these days.
