If you have ever been robbed or had your property broken into, you know it is not a good feeling. It took not one, but two break-ins to my workshop before I knew something had to be done to stop intruders. And every good defensive driver knows: the best defense is a good offense. So that it what I set out to do.
First I needed a secure detection system. To accomplish this I installed two hard-wired motion detectors and a magnetic door sensor. The main controller, an x86 based computer system, has a redundant backup battery power supply in case an intruder attempts to kill the power. To alert the neighborhood of an intrusion, there are two loud sirens inside the workshop and a loud bell on the roof. In addition, there are strobe lights and red siren lights inside the room. To expel the intruders promptly after a break-in is detected, the following occurs:
1) The sirens, alarms, and lights turn on
2) An intimidating voice says, "Intrusion detected! Initiating auto-lockdown sequence!"
3) A 2,500 lb thrust motor slowly closes the seemingly manual lift workshop door
4) The voice then says, "Releasing toxin into atmosphere."
5) An explosively charged toxin (which I would prefer not to mention by name) is spread from the corner of the room into the air
6) The assailant flees the scene.
