Title: 506T Audio Sensor
Review: This sensor senses high frequency sounds such as, glass breaking, brake squeaks, etc... which sends a signal to the alarm to go off. If its too sensitive it will go off by sounds brake squeaks or trucks letting pressure release next to your car. Adding this layer of security is a plus. Works well and its adjustable, recommended to any car security system.
