Ultrasonic Rear Collision Warning System (S.ZD.397.HDF)Return to Collision Warning Systems


The Zone Defense Ultrasonic system is our automotive-grade collision warning system. Most over-the-road fleets don’t need the cost associated with an industrial-grade sensor system. They need a warning system that works, can handle their daily environment, and is within the constraints of their budgets. This system is ideal for automotive/SUV, Box/Delivery trucks and utility vehicles.

  • Benefits
    • Small sensors don’t require a lot of space on the back of the vehicle for installation
    • Detection zone is preset at 5 meters, which is optimal for over-the-road maneuvers
    • Audio alerts include both beeping and distance notification:
      • Driver receives an audible notification of distance from sensor to detected object along with an urgent STOP when they are too close
      • An audible beeping alert increases in frequency when your vehicle is getting close to detected objects
    • When combined with a Zone Defense monitor and camera, the detection zone and distance to detected object is overlaid on the monitor, providing the driver both a visual and audible alert
  • What’s in the Box
    • Four sensors
    • Four sensor cables (3 Meters)
    • Control Box
    • Camera cable (3 Meters)
  • Available options:
    • Add Monitors (link to monitor section)
      • When a monitor is added, the sensor information is overlaid onto the monitor showing the operator the distance between the sensor and the detected object.
    • Add Cameras (link to camera section)
    • Change monitor visual alert measurements from Feet to Meters
    • Need longer cables? Then chose S.ZD.397.HDF.V2. You get the same benefits mentioned, with longer 5-meter sensor cables.
