alarm sensitivity

[eclique]

Ok I posted a message in technical but no reply. So here goes again.
Any experience with adjusting the alarm sensitivity if any. The people here in Castle Rock Colorado are real a** Holes. I have aquired several door dents some with the offending cars paint. I would like to set the alarm to go off when the damage my car if for no other reason than to point a finger at them when caught in the act. Selfless inconsiderate boobs. Help
