I installed a remote start pager alarm on my e34. Its got a shock sensor mounted in the center console so my sensitivity is nearly equal all the way around the car.
I've also got my windows to roll up whenever I arm the car, the sunroof too.
This is an easy and cheap mod to do to your alarm.
I connected my aux output on my alarm to have a timed output of 30 seconds to cover the amount of time required for all 4 windows to roll up and the sunroof to close.
When you connect your lock wire up, connect either the timed aux output or just install a timer relay on your lock output on your alarm. This will provide a 30 second latched output on the lock circuit.
I would suggest using a relay if you plan on using the aux output.
Ive also got pin switches on the hood and trunk.
