Program Information

For more intensive monitoring, in conjunction with Pretrial Supervision, a defendant may be court ordered to an electronic monitoring device. Electronic monitoring allows for close supervision of a defendant while in the community. Schedules are set for defendants who are allowed to work, attend school, counseling and other appointments required by the court. Restricted areas can be established in cases where victims are involved. Progress and compliance with conditions of release are continually evaluated and reported to the court.

The following are types of electronic monitoring devices utilized by Oakland County Community Corrections Division:

  • Global Positioning System (GPS)
  • Transdermal Alcohol Monitoring
  • Breathalyzer Monitor
  • Ignition Interlock
Transdermal Alcohol Tether

These devices use transdermal (through the skin) analysis to determine the offender’s Blood Alcohol Content (BAC).  It also monitors body temperature and distance between the leg and bracelet to detect attempts to tamper with or obstruct the unit.  

Requirements include:

  • defendant must follow all rules and regulations of the Pretrial Supervision Tether Unit
Global Positioning System (GPS) The defendant's movements are tracked via satellites and reported at regular intervals, in the event of a violation, the defendant's movement is reported in as close to real time as possible. Exclusion zones for areas such as a victim's home, work, school or church, are programmed into a map with a predetermined radius. If the defendant enters one of these exclusion zones, the victim and Pretrial Supervision Tether Unit are notified immediately, allowing the victim to enact a safety plan. Conversely, if the defendant is required to remain in a specified area, such as home, work or school, for a period of time, an Inclusion Zone is programmed into a map. Appropriate candidates for GPS include defendants charged with Domestic Violence, Assault and Battery, Criminal Sexual Conduct, or any crime with a victim. Requirements include:

  • defendant must have a stable address
  • defendant must have a standard power source
  • defendant will be given a schedule to assure GPS device is fully charged
  • for offenses with a victim, the defendant should be held in custody until installed on GPS tether to insure the victim has been contacted and exclusion zones are established
  • defendant must follow all rules and regulations  of the Pretrial Supervision Tether Unit
Transdermal Alcohol Monitoring Using transdermal technology this type of equipment detects the presence of alcohol through the defendant's skin. It also monitors body temperature and distance between the leg and bracelet to detect attempts to tamper with or obstruct the unit. If the unit detects alcohol it will test at least every 30 minutes until alcohol is no longer present. Requirements include:

  • defendant will be required to have (or have access to) a digital or analog landline
  • defendant must follow all rules and regulations  of the Pretrial Supervision Tether Unit
Breathalyzer Monitor This system does not require the defendant to wear any type of ankle bracelet. Rather it randomly monitors and screens the defendant for alcohol while he/she is at home. The defendant must submit to a Preliminary Breath Test (PBT) when the unit "calls" their home. The unit is also equipped with a camera and may ask the defendant questions in order to verify identity. Results of the PBT's are reported to the monitoring center and forwarded to Pretrial Supervision Tether Unit for follow-up.  Requirements include:

  • defendant must have a stable address
  • defendant must follow all rules and regulations  of the Pretrial Supervision Tether Unit
Ignition Interlock An Ignition Interlock device is a breath analyzer installed into a vehicle to prevent a person from starting the engine if alcohol is detected in their system. The driver must blow in the device and pass a breath alcohol test before the vehicle will start.
