Generation III Bracelet
Alcohol & Marijuana Sensing

The new redesigned Generation III alcohol and marijuana sensing house arrest ankle bracelet is worn around the ankle and is fitted close to the surface of the skin and has multiple features to provide complete monitoring of offenders. If alcohol is consumed, it is metabolized and diffuses throughout the body. This alcohol is present in various bodily substances such as breath, blood, urine and perspiration. Some percentage of consumed alcohol is metabolized through the skin.

The primary sensor measures the specific characteristics that are chemically emitted transdermally from the body and measured against a pre-test baseline trip level for each offender.


Additional sensors are used to detect tamper events and battery voltage levels. The bracelet and handheld GPS tracking device are electronically tethered together so that the bracelet and tracking device cannot be separated.

The offender cannot simply hand-off the tracking device to another person. Any attempt to remove the bracelet will cause sudden changes to be detected in the sensors which will send an alarm notice.

The bracelet casing is made from a high grade ABS plastic and the straps are made of Santoprene (a high grade plastic/rubber compound). It weighs approximately 6.5 ounces. Power is supplied by an internal rechargeable battery system. The bracelet is light, compact and can be worn without much discomfort.

Cellular Network

A cellular wireless network is used so the alcohol and marijuana house arrest bracelet is not hindered by the drawbacks of landline telephones (some offenders do not have landline telephone service anymore due to the prolific use of cellular telephones).

Geo-Fence and GPS

A judge, when setting the conditions of probation/house arrest, may stipulate that an offender not use alcohol or marijuana and that the same offender must stay out of certain geographic areas. In matters involving domestic violence offenders or sex offenders, the active GPS technology offers the option to create a “Geo-Fence” whereby a specific location or geographical area may be identified as a restricted area to the offender.

The GPS tracking feature archives and stores the location tracking information in a date/time fashion. This feature provides a chronological listing of the offender's whereabouts and shows when the offender arrived and left a particular location such as home, work, or school.

Client Alerts

A unique automated voice audio message and signal tone will remind the offender that the batteries in the ankle bracelet and/or the GPS tracking device are due to be recharged.

Removal Detection

The bracelet and the tracking device are electronically tethered together and therefore the bracelet and the GPS tracking device cannot be apart without alerting the probation officer. The offender cannot simply hand-off the tracking device to another person.

Any attempt to remove the bracelet will cause sudden changes to be detected in the proximity sensors which will send an alarm notice. At 6.5 oz, the bracelet is light and compact and able to be worn without much discomfort.

Monitoring Software

The monitoring software is a web based user interface.  No software packages are installed directly on the service provider’s computers.  Offender information, baseline sensor data and GPS settings are easily controlled.  Violation alert notifications are sent via SMS text and/or email.  Intuitive screen design and function provides easy monitoring.


Create your offender reports by simply using the computer Print function.  The report are automatically formatted for 8½x11 paper – no copy and paste methods.  Reports are customized by selecting the specific data and date/time range.

Offender monitoring data is stored for 3 years as a standard retention policy in our world class data center.

Smart Phone Compatible

The TT Tracking user interface is configured for alternative viewing on your smart phone or tablet.  With real time tracking of monitored offenders the service provider or officer can track down individuals who are moving.

This new redesigned Generation III alcohol and marijuana sensing house arrest bracelet is now available. It is a powerful tool for courts and probation departments as an alternative mode of sentencing due to overcrowded jails.

Probation departments spend most of their time handling offenders on drug and alcohol related matters. We now have the technology to monitor alcohol and marijuana usage in offenders and to provide probation departments with on-line information for each monitored offender.

It is no longer necessary for probation officers to require offenders to come in for random drug and alcohol testing. If alcohol or marijuana usage is detected by the equipment, the offender can be summoned and ordered to come in for additional testing.



Our products and services are designed for local Service Providers, Bail Bonds Providers, Courts, and Law Enforcement.
