RemoteMDx’s TrackerPAL keeps an eye on sex offenders on parole from a state-of-the-art monitoring system. Once the ankle system is set up, the TrackerPAL tracks the parolee’s every movement, and even limits where he or she can go. When the sex offenders move into areas they are not allowed to be in, an alarm will notify the monitoring center, which, in turn, notifies authorities. The TrackerPAL has two-way communication, and it is tamper-resistant.
