Smoke Alarm   (+2)  [vote for, against]
Fills home with smoke as a defence against break-in's

When the home's motion detectors, laser grid or other measures detect an intruder in the home, artificial smoke machines in strategic places in the home (perhaps concealed in the ventalation system) activate filling the home completely with smoke, so the culprit finds stealing possessions or harming the occupant as difficult as escaping. Upon activation of the system the authorities are also notified and an alarm sounds, to further incite more panic in the trespasser.

Similar technology can be incorporated into a car alarm.

a good use for all those stockpiled chemical weapons. Can you make a car-alarm version?

Baked to a crisp. There are quite a few companies that will install this for you.

could it play snap and pop sounds to make 'em think there was a fire?

Yes, this is Baked. The systems sometimes use pyrotechnic smoke and sometimes oil mist smoke (like a conventional theatrical smoke machine) but they're becoming quite commmon in the UK. Cheap, non-lethal and effective.

Flashfog security in Canada does exactly this and they even put a strobe light with it . They don't use smoke though, but fog. see www.flashfogsecurity.com

Theatrical smoke makes it particularly hard to breathe.
