i was looking at a car alarm with immobilizer here:
http://www.aboutsound.co.nz/Dynatron.html
and the first model of car alarm(which is the cheapest) says:
the system is armed passively by the driver every time he/she wants to start the car
then it says:
opportunity for starting is allowed within 40 seconds before the system will automatically immobilize
so does this mean if a thief broke into my car they can do whatever they want to hotwire it as long as they do it before 40 seconds?
and how do alarms with glass break protection work? do they put a sensor on the window and if the window is smashed will the alarm go off? and will i need to get a new alarm sensor if this happened?
