The Audiovox system takes blind spot detection to a whole new level thanks to its flash memory feature. This feature allows the system to identify and memorize accessories such as bike racks and spare tires that are often mistaken as moving cars. These accessories can result in false alarms, but the Audiovox sensors are programmed to detect cars and other obstacles that are six feet away from the bumper. The sensors are accompanied by a buzzer with an adjustable volume as well as LED indicators and can be programmed more than once. They can also be mounted in the back or the front using waterproof connectors. Unlike the Crimestopper system, the Audiovox kit has two sensors instead of four but car owners can purchase additional sensors in order to make the most out of this after market product.
