My vehicle has been compromised yet again in the parking garage I park in at home. Looking to possibly deter possible vandalism or theft in the future. Any fancy car alarms that include or accept proximity sensors? I figure if I can cover most of the windows, it may help. Since the garage has attendants in it at all hours, so it may draw attention. If possible, I'd love the alarm to be a constant buzzing or something, not a "beep beep beep". Something that buzzes until they leave the field.
