Instead of yet another source of noise pollution, if there is an electronic device, I'd recommend a GPS transponder that is installed in the frame with some way to work as an antenna... a LoJack-like device pretty much.

The first rule about alarms is that one, someone must hear it, second, someone must care about it to do something other than look in that direction, either because its their own property, or the person is paid to care about it. House/business alarms call central monitoring stations which send out security or the PD. Anti-shoplifting alarms have clerks to monitor and intercept people trying to yank electronics and such off tethers.

This is why vehicle alarms are next to useless these days.
