The Challenge ProTech has to track released criminal offenders under community supervision. The offender is fitted with an ankle bracelet and given a PTD that monitors the proximity of the ankle bracelet. Corrections personnel can declare any area off-limits and establish a daily schedule for the offender. Off-limit areas and daily schedules are programmed to the offender s PTD using cellular communications. Victims at risk also receive advance warning that the offender is in the hot zone, giving the victim the necessary time to move away from the offender.
Victim notification can occur via fax, pager or cellular telephone.
