Types of Driveway Security Systems

Magnetic Detectors

• According to Driveway Motion Sensors, a magnetic-detection driveway device is buried underground beside the driveway. It detects moving metal as it approaches the driveway. It will not, however, alert owners to people or animals.

  Absolute Automation notes that magnetic-detection driveway devices tend to be more expensive than their infrared beam counterparts.

Infrared Beams

• Infrared beams are wireless motion sensors that detect vehicles and people (with the occasional false alarm for animals), according to Driveway Motion Sensors.

  When a car or person passes through an infrared beam, the owner can be alerted by a telephone call, chimes or bells, lights, or strobe lights on the property, according to vendor Chime City. This is similar to other types of driveway security devices.

Hose Sensors

• Hose sensors are as simple as they sound. In terms of driveway security, a hose sensor detects when a vehicle has run over it, alerting the owner to a visitor, according to Driveway Motion Sensors. Hose sensors are noticeable and seem better suited for businesses that need to be alerted when deliveries and other visitors arrive.
