Guardian Alert® rear sensing device offers drivers Doppler radar technology

    The problem of vehicle blind spots is a concern for vehicle owners, and ironically, drivers who often have the most child-friendly vehicles – vans, SUV’s, high profile pick-up trucks and certain cars – are often the ones with the largest blind spots and worst rear visibility.  In response to the need for a dependable, easily installed and affordable rear-sensing safety device, Sense Technologies, Inc., www.sensetech.com, has developed the Guardian Alert® Doppler Awareness System, which uses sophisticated Doppler microwave technology to warn drivers of impending hazards when backing up.  Able to easily detect objects, Guardian Alert® is compatible with any vehicle, is easily installed in minutes, and it alerts drivers using a highly accurate, maintenance-free system that is impervious to weather conditions and dirt.

     Guardian Alert® provides drivers with a three-stage audio-visual warning system that not only detects obstacles in the path of a car traveling in reverse, it measures diminishing distance, and eliminates false warnings for those objects that pose no threat of collision.  Drivers are alerted to danger by a warning indicator inside the vehicle.  An exterior sensor affixed invisibly behind the rear bumper or inside a trailer hitch (like any hitch-plug installs), transmits data and alerts the driver of potential hazards – such as pets, small children, pedestrians or bicyclists – when backing up.  Guardian Alert®’s Doppler technology is impervious to weather-related performance restrictions and needs no ongoing maintenance to perform properly.  Lighting conditions, precipitation, dust and grime or severe road conditions will not affect Guardian Alert®’s ability to deliver accurate information to the driver.

     In tests against other warning technologies, including optical, infrared and ultrasonic, Guardian  Alert®’s Doppler microwave sensing offered drivers the most overall reliable means for avoiding potential rear hazards.  There were fewer incidences of “nuisance” notifications, and Guardian Alert®’s “awareness zone” was the most comprehensive on the market, extending from the rear of the vehicle outward nine feet for the width of the vehicle.  Vertically, the coverage area begins at ground level and rises five feet. 

     Sense Technologies National Sales Director Tim Goldsbury states, “Some reverse warning systems leave unsuspecting drivers with blind ‘holes’ large enough for an adult to pass unnoticed, defeating the very purpose for which these systems were created.  The Guardian Alert® system can detect objects posing an impending danger behind a backing vehicle in all weather and lighting conditions.  The product can be fitted on any type vehicle in minutes, and there is no visible indication of the product once installed to detract from the exterior styling of the car.”
