Preferred Security Components, Inc (DBA Cartell)

All Cartell systems are powered by magnetometer technology. That means they are only triggered by moving steel, NOT by light, motion, heat, or pressure. Because of this, if it’s activated, you can be sure there’s a vehicle in your driveway. Our inventor, Dr. William Flook, was introduced to this technology after WWII when it was used to detect and detonate shallow water mines. He was a pioneer in applying it to home security in the 1960’s and Cartell was the first to introduce it to the industry in 1975. “People don’t buy what you do; they buy why you do it. The goal is not to do business with everybody who needs what you have; the goal is to do business with people who believe what you believe.” Simon Sinek
