i don't get it. like alpine's proxy sensor, it detects all movement within some range around your car and it works like this. if it chirps 3 times or 4 times within 15 min or something i forget, the alarm will go off. if someone keys your car, the alarm will go off cuz there's movement. how can you possibly cheat proxy sensor, since it picks up all movements around ur car? even though he could pass the first layer of security, either the inner zone proxy or shock sensor is gonna pick up the movement. there's no way that someone can pass all the security without causing the car to sound and not to wake up my neightbors. some of my neighbors are super sensitive about noises. they can get pissed off about me cranking up my music while i washed my car at noon. so it is sometimes a good thing that ur neighbors are a weirdo or freak
