911 Communications

911 dispatcher


The McHenry County Sheriff’s Office Communications Center receives 911 calls from all unincorporated areas of McHenry County, as well as from the jurisdictions of 10 outside police agencies and 4 fire/rescue departments. A total of 15 organizations rely on the professionalism and skill of our 911 dispatchers.

All dispatchers are Illinois Law Enforcement Agencies Data System (LEADS) certified and also certified through the International Academy of Emergency Dispatch as Emergency Medical Dispatchers. With this certification, our dispatchers are able to issue medical instructions while injured or ill persons are awaiting the arrival of paramedics.

The Sheriff’s Office utilizes the STARCOM 21 800MHz radio platform. This system allows for clear communications and correspondence with nearly all agencies statewide.

Court security officers open and close the court and are responsible for the safety and security of the judge, court officers, and the courtroom. Whenever a jury is sequestered for overnight deliberations, Court Security Officers remain with the jury to provide security and ensure that no outside contact is made with jurors.
