In one the most unusual technology offerings at the 2013 Border Security Expo in Phoenix, AZ, Sentry Visions LLC, of Siloam Springs, AR, introduced its patent-pending concept of applying a fluorescent, non-toxic earth mineral-based material on road surfaces on the U.S.-Mexican border in areas where there is a history of illegal border crossings.
According to Ron Hutcheson, president of Sentry Visions, the company’s fluorescent material, which draws radiation from the sun and glows during the night, clearly shows footprints and other traffic when disturbed and leaves a clear trail which could be used by Border Patrol agents in the states of Texas, Arizona and New Mexico to stem illegal border crossings.
In a conversation with Government Security News, Hutcheson showed photos of the fluorescent earth mineral and indicated that once it is applied on a “base road,” it will reflect clear footprints or other evidence of persons crossing the portion of the road where the material has been applied. He adds that the material experiences only a five percent loss of brightness during a 10-year period.
