I have seen few systems today that match the quality and features of an older Alpine unit I purchased back around 1989. It handles everything with excellent reliability so far. The one extra thing I did was use a battery of relays to isolate the unit from any existing relays and voltage feedback. It is an alarm with window actuators, door locks, door open sensor, glass break sensor, light sensor, a louver sensor has been added, it operates the lights and airhorns with a siren, has an ignition lock-out, key-in-ignition sensor and can be set for passive or active engagement. I just recently obtained the gear to install a door launcher that the key fob will activate and I still have room for a trunk release. It is so integrated into the car now that I have been keeping an eye on e-bay for another unit in case I need spare parts. So far so good though. It is an Alpine 8126. Harold McElraft - 3354
