Anyone get the factory Honda Security system?

How well has it worked for you?

Is the glass breakage sensor prone to false alarms? I.e. from thunder storms or by a car with loud exhaust passing by?

Anyone add additional aftermarket sensors to the alarm i.e. Motion/shock sensor and proximity sensor?


Thanks!
