The Corrections Division is comprised of jail operations, courthouse security and electronic home monitoring.





The current DeKalb County Jail opened in June 1980. The jail capacity at that time was 64 inmates. In the late 1980's the jail became overcrowded. With the approval of the State of Illinois Detention Standards, beds were added which increased the capacity to 89, which remains the current capacity. In 2012 the mail averaged 136 inmates per day. This is the highest annual average population for our jail.





The presence of Sheriff's personnel at the courthouse provides the criminal justice system, its employees and the public a safer and more secure environment. The deputies working at the security station scan items brought in through an x-ray machine, insure all those entering pass through a metal detector, assist citizens and make arrests as needed.





Electronic Home Monitoring (EHM) offers an alternative to incarceration by monitoring the degree of compliance to house confinement. Under EHM a client must wear a Global Positioning Satellite Transmitter, which sends an encoded signal to the monitoring center. This allows the Sheriff's Office to continually monitor the client's location and also alerts us if they leave their home at an unauthorized time.
