Car Alarm Sensors Explained: Which Ones Do You Need?

Not sure which car alarm sensors to buy? This guide runs through all the main types of car alarm sensors and explains which are best for your vehicle and your needs. Using a Viper alarm on the bench, I demonstrate door and bonnet switches, shock and impact sensors, dual zone field disturbance (microwave) sensors for convertibles and soft tops, glass break (audio) sensors, ultrasonic sensors for tinted windows and vans, digital tilt sensors to stop wheel theft and towing, PIR sensors for canopies, and magnetic reed switches. Learn how dual zone warn-away and full alarm triggers work, and which sensors suit different vehicles.
