what is the difference between two way and one way security systems in car alarms?
One-Way are your run of the mill alarms. Remote has a few buttons, when someone brakes into your car the horn will sound. Two-ways work the same but notifiy the user of an security breach. The remotes usually come with a LCD display of a car and when you car doors are broken into and opened, the car horn will sound and also the remote will sound notifiying the user of someone breaking into there car.
