Many cars have a siren mounted so as to announce to the World somebody is Stealing or Messing About with your
car. Most people Ignore them, as False alarms are the
main thing these devices announce.
So... My idea is this: Mount the Siren (120db or louder)
INSIDE the car. The firewall under
the dash is good, so is
the package shelf [perhaps as part of the 3rd brake light].
How it Works: The Goblin forces entry into the car,
tripping the System. It waits maybe 20-30 seconds, then
sounds a warning "burp". At the end of the wait, it Locks
the car doors and lets the Siren go for about 20 seconds.
It then un-locks the doors and gives the now sonically ten-
derized thief have a chance to get out. Then, it re-locks,
gives another 20 second blast, and starts blinking the car's
lights to announce it has a trapped Goblin onboard, and would the Police please pick up whatever is left.

[goibneu] this siren will be ignored in exactly the same way that a normal alarm is - you've not solved that problem. |
|
| |
Secondly, why would a thief enter a car and shut the doors? |
|
| |
Thirdly, do thieves use the door anyhow? Don't they break windows and just grab whatever they can? |

I remember reading recently of an alarm with specific audio characteristics that induce unpleasant physiological effects. I can't find a link to that, so I linked to a similar technology. |
