how sensitive is our alarm?(factory)
i am just wondering..because i was testing my cars' alarm systems...
when i tested my bmw i put th ewindow down a little bit and locked the doors(set the alarm)...the second i put my hand through the window teh alarm went off...i tried it with the g and i unlocked my door and even sat down and nothing went off..
so i am wanting to know under what circumstances do our alarms go off?
thx for feedback!

Most OEM systems have to compromise between overall security and false alarms. No one wants to own a car with an alarm that goes off all the time.
Everytime you add a sensor you greatly increase the chance of a false alarm. Motion sensors are notoriously bad for this, and I've never actually seen a car that had a motion sensor installed on the assembly line. Was the motion sensor a dealer add on?

ive had it for bout a month or 2 now...never had a false alarm..only when i was testing it...i think its great that it goes off when anything goes through the window when its open....

I installed an aftermarket shock sensor myself and it works like a charm. Depending on the sensitivity level, a knock on the window will set the alarm off.

has anyone thought of adding this

I'm assuming you would need to wire it up to a power source so that it only had power when the ignition was off. Otherwise it would be unable to reset the current vertical / horizontal of the angle of the car when you turn off the ignition.
