Electronic monitoring provides a low-cost means of safe, community supervision for lower-risk inmates. Contrary to popular belief the tracking devices cannot be removed without sending an alert to a base station monitored by the tracking agency. Each unit emits a frequency a couple of minutes which allows supervisors to pinpoint an offender’s location at all times, according to their pre-planned schedules.
There are also alcohol monitoring systems in place to randomly check an offenders drinking habits. An in-home breathalyzer records, via telephone, the amount of alcohol consumed by the offender. On-board cameras make no mistake about who’s submitting the breath sample.
Real-time maps show the offender’s path of travel. Forbidden zones are marked in red, alerting authorities whenever the suspect strays into unauthorizes areas.l
