I’m in need of a “driveway” monitor. My customer wants to know when a car enters their driveway, its about 150′ long and there is no power at the entrance. What can I offer?



Optex and STI have driveway alert solutions for this. It’s a battery or solar powered transmitter that senses the presence of a vehicle and transmits a signal to the receiver located in the home. The magnetometer senses any large metallic (iron or steel) object having a magnetic field and causes the sensor to transmit to the receiver. Generally, it’s a 500′ line of sight from receiver to transmitter. The list price ranges from $200.00 – $250.00.
