As I understand it ... the most advanced security even on the 802a trucks is interior only.
If someone throws a rock that smashes glass, it's not the glass smash (shock) that sets off the alarm but it's the rock setting off the interior motion sensor.
I'd like the extra chirp if someone is rocking the rig or thinking about doing something dumb.
Gotcha, think you're right on the money with that description! thx!
