Review: Best Car Alarm Systems
When it comes to protecting both your car and your valuable possessions inside, there is no substitute for a good car alarm. A good car alarm should serve as both a deterrent and a response system. The better ones include a 2-way pager system that alerts you when your car is being broken in to, which can give you those critical few moments to take action to stop a burglary from taking place. Otherwise, the sound of the alarm should draw enough attention and radar to the car thief that the burglary attempt either is aborted or foiled by law enforcement officials. Take a look at our list of the best car alarm systems in 2021.
