Connection to the CANBUS eliminates the need for many of the analog necessary in traditional, hard-wired, security systems cutting the installation time, in many cases, down by as much as 50%. CANBUS communicates with most of the electronic security and convenience systems throughout the vehicle, so the alarm remains in-sync with the vehicle at all times. When the vehicle is equipped with a factory security system, it works in sync with Directed CANBUS security system and all factory functionality is retained.
