Electronic Monitoring Center Overview
The DOC Electronic Monitoring Center provides electronic monitoring services to the Division of Community Corrections, Division of Juvenile Corrections, local law enforcement, and county human services agencies.
The monitoring center provides 24/7/365 monitoring services for offenders on electronic monitoring.

sends information to a receiver installed in the offender’s home. If the offender is away from their home outside their curfew or the device is tampered with, the Electronic Monitoring
Center is alerted.

The monitoring center functions as the point of contact for national law enforcement agencies confirming the wanted status of offenders on DOC supervision and Wisconsin law enforcement queries regarding individuals on DOC supervision outside business hours.
