Found this on the net,
AutoTaser ($160 after rebate). It's powered by three 9-volt batteries and 8-10 hour daily usage will last about 6 weeks.
If the AUTO TASER’s ultra sensitive vibration detectors sense an intruder, a screeching 120 to 130 decibel alarm is sounded as a warning before aggressive countermeasures are initiated. Five seconds later, a field of electrons completely surrounds the unit. Any attempt to touch the AUTO TASER zaps the thief with an unforgettable, yet non-lethal 5,900 milliwatt (50,000 volt) electron pulse. "
