Pretrial - Felony - Misdemeanor

For more intensive monitoring, in conjunction with Pretrial Supervision, a defendant may be court ordered to an electronic monitoring (EM) device. EM may be used to restrict or supervise a defendant's movements or to monitor a defendant's abstinence from alcohol.

The following are types of EM devices utilized by Oakland County Community Corrections Division when ordered by the court:

• Transdermal Alcohol Monitoring
• Global Positioning System (GPS)
• Portable Alcohol

Rules and regulations of the Pretrial Supervision Tether Unit.

All EM options are provided by third party vendors. The costs of these systems are the responsibility of the defendant per MCR 6.106. Costs will vary based on the type of EM required.

Transdermal Alcohol Tether

These devices use transdermal (through the skin) analysis to determine the defendant's Blood Alcohol Content (BAC). They also monitor body temperature and proximity between the leg and device which are features designed to detect attempts to tamper with or obstruct the unit.

Requirement for Transdermal:

• All rules and regulations of the Pretrial Supervision Tether Unit are followed

Electronic Monitoring - Alcohol Rules and Regulations

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 tracked 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 GPS staff are notified, allowing the victim to enact a safety plan. GPS may be used in, but not limited to, cases involving a victim such as Domestic Violence or Criminal Sexual Conduct.

Requirements for GPS include:

• A stable address
• A standard power source
• All rules and regulations of the Pretrial Supervision Tether Unit are followed

EM devices are provided through third party vendors. Devices may be installed at the vendors location or prior to the defendant's release from custody.
