a_integra_97...every alarm that i have installed has a shock sensor that can be adjusted to diff sensitivity levels.

alarms that we carry all have back-up power sources that enable the alarm to go off for up to 48 hours if the battery were to be disconnected. all have ignition cut offs also. want to silence the alarm speaker? cut the speaker wires, common sense.

but either way, a smart thief will get past an alarm with no problem, there are many strategies. if they were a little bit smarter they would have high paying jobs and would be making big dollars legally.
