For customers who wish to detect ONLY vehicles entering or leaving their property, magnetic vehicle probe driveway sensors are the way to go. They will only detect larger moving metal objects like cars and trucks. People and animals will not trigger the sensor.
The larger the metal object is and the faster it is moving the easier it is for the sensor to detect it. Many of our magnetic vehicle probe alarm systems have adjustable sensitivities allowing customers to use them in a variety of applications and settings.
