Extends Vehicle Detection Range

Designed for use with the STI Wireless Driveway Monitor, this sensor detects when a vehicle enters or leaves a monitored driveway. Movement of any large metallic (iron or steel) object close to the driveway sensor will transmit a signal to an STI receiver.

  • Detects vehicles coming up your driveway
  • No difficult underground wiring
  • Will not be triggered by animals, people or shadows
  • Sensitivity options: low, medium, high

How It Works

The driveway sensor uses a patented magnetometer sensor system. Movement of any large metallic (iron or steel) object with a magnetic field causes the sensor to transmit to the receiver.
