North Andover, MA – July 13, 2010 -- Portman Security Systems Ltd, http://www.portmansecurity.com a leading manufacturer of GPS tracking devices, announces a new line of self-contained, zero-power-consumption tracking devices for mobile assets. The new devices are the solar-powered TLU, patented wind-powered WP100 and the solar/wind-powered WP 300.
According to Ed Nevins, Portman Security Systems’ Senior Director, “Our new line of green devices is designed to sit unobtrusively atop a trailer. Totally weatherproof, these independently powered devices deliver reliable GPS tracking and monitoring, accurately reporting location, temperature changes, tire pressure and door access. The sun and wind do all the work,” he said.
The Portman TLU is a solar-powered logistics device combining all the functionality of a GPS tracking unit, eliminating the need to connect to truck’s power supply. It houses its own motion sensors and GPS & GSM antenna, capable of operating up to a month without sunlight. The STLU variant can automatically switch over to the Iridium Satellite Network to continue reporting data in remote locations where there is no GSM coverage.
Portman’s WP100 is a patented, wind-powered GPS tracking device, operating via an independent wind-powered turbine generator. Perfect for vehicles constantly on the move, this self-contained unit installs easily, charges its own batteries while in motion, and provides the necessary telemetry to track all mobile assets.
“The best of both worlds,” continued Mr. Nevins, “is our new WP300, containing both the
patented turbine charger and solar panel in one compact, weatherproof package. The unit’s indefinite battery life and wide range of sensors provide time-stamped, reliable reports on the status of trailer contents and real-time GPS tracking data.”
