Developed specifically to monitor non-powered, detached equipment such as trailers, Teletouch's asset tracking device gives companies the ability to pinpoint the location of these assets. The battery-powered, self-contained, satellite-based mobile asset-tracking device provides location information on trailers, allowing remote monitoring and tracking of their movement. Assets equipped with Teletouch's solution, which customers can interface with the unit via PDA or laptop computer, report back to the monitoring station on customer-defined intervals and upon the occurrence of user-defined events.
