If you are talkinga bout Anti-Theft, then it's use to prevents you car to be stolen, it's not an alarm.
Many stock car alarm only sounds when the doors are open, but no shock impact protections.
In my case, I am using my stock alarm + Clifford alarm additional shock and zone sensor. It would also page me within a mile. It kinds of give me the peace of mind when I park outside or going to the mall while the car parked outside. I also like the fact that I would be page in case of hit and run or maybe someone open their doors to wide and hit my car...! |
