This might be a rare question, but wondering if anybody has put an after market alarm system on their Model S. My car got broken into this afternoon and the car's alarm didnt even go off. I was under the impression that the car has an alarm system. Apparently, if somebody breaks your window and doesn't open the door, the alarm doesn't go off and you don't get any notifications. So, with that being said I am now looking for putting an after market alarm system in my car. Does anybody have any recommendations in NOVA area for somebody who has done that on a Model S or of a good system? I had front and rear camera installed, so I at least know what this individual looks like and will be giving that to the detective tomorrow. Thanks for any input!
