Electronic Offender-Tracking Solution

The number of accused and convicted criminal offenders who are monitored with ankle bracelets and other electronic tracking devices rose sharply in recent years.

The GPS Offender-Tracking bracelets are not just devices worn around ankles. They're part of a complex system for monitoring the movements and activities of pretrial defendants or convicted offenders on probation or parole. The system offers a robust integration of tracking, communication and mapping technologies that enable operators to efficiently track offenders, indoors and out, at varying levels of intensity.
