Cartell, located in Salunga PA, introduces a new way to detect vehicles.

Salunga, PA (PRWEB) June 26, 2014

Cartell makes a driveway alarm system that makes homeowners aware every time a vehicle enters their driveway. There are a lot of systems that do that, but not exactly the way Cartell does. It is the technology Cartell uses that gives it an edge in the market and the right to claim it is virtually false-alarm proof.

The car detection component of the Cartell system is based on magnetometer technology. That is, it uses the earths magnetic field to detect vehicles. When the sensor probe is buried beside the driveway, it detects fluctuations in the earths magnetic field caused by moving steel. The detector is neither a motion detector nor a presence detector. It is a moving steel detector.

Magnetometer technology is not new. In fact, patents for it date back to the 1930s. Its greatest development occurred during World War II. It was used to detect and detonate shallow water mines in the south Pacific. It was during that time Dr. William Flook, Jr. was exposed to the technology and a couple decades later, created a vehicle detection system for the driveway. He called it Cartell. In 1975, Dr. Flook sold the rights to the Cartell name and product to Preferred Technologies Group.

The fact that Cartell is based on magnetometer technology means there are no false alarms caused by animals, people, blowing leaves, wind and weather, says Jonathan Bohannon, President/CEO of Preferred Technologies Group. Since the probe only senses moving steel, we do not fear putting an audible device on our system because we know the homeowner will not be awakened in the middle of the night by false alarms.

Cartell, founded in 1975, is a division of Preferred Technologies Group, located in Lancaster County, Pennsylvania. Starting with its groundbreaking use of magnetometer technology for vehicle detection, Cartell has led the industry with innovation, functionality, quality and value. The dependability of Cartells products far exceeds the industry standard and is backed by a five-year warranty. Every Cartell product is quality-made in the U.S.A. and sold by a national network of fine distributors.
