Open Source Burglar Alarm Software

The LS30 project is open source software to control an LS-30 Burglar Alarm system. The LS-30 is a hardware designed for self-installation in a home or business. It communicates wirelessly with its devices, which include:

  • PIR (Passive Infra-Red) burglar sensors
  • Remote control key fobs
  • Solar powered outdoors siren
  • Magnetic reed switch door sensors
  • Smoke detectors
  • And more.

It is very configurable, and according to the vendor has “more features than any other system available”. Except perhaps for very expensive commercial systems. What appealed to me though, was the ethernet interface – I can plug it into my network and (hopefully) configure it remotely.

I have begun to reverse-engineer the LS-30 communications protocol. Furthermore, I have released my code under the GNU General Public License (Version 3) so others in the community can benefit from this effort (and help me finish the job).
