Each agency provides the RHCS local monitoring center with a set of guidelines specific to each offender. Many agencies have discovered that our monitoring programs assist not only tracking, but also the rehabilitation of the probationer. By providing a structured program with quick response to any violation, offenders develop positive, habit-changing behaviors which are often carried forward after the completion of the tether program.

Product Overview
BI TAD BI TAD is an alcohol and curfew monitoring device that will soon be available from BI Incorporated to corrections agencies nationwide. The ankle-worn device uses transdermal technology to constantly monitor whether or not an individual has been drinking. An absorption sensor rests firmly against a client's bare ankle and monitors alcohol levels through the individual's perspiration. If there is alcohol data to report, TAD transmits the data to a receiver in the client's home when he or she comes within range of the receiver. Data is then reported to the central monitoring computer.

TAD also monitors client curfew using traditional radio-frequency technology to detect presence or absence in the home. By providing this dual monitoring functionality, TAD virtually eliminates inventory management issues and saves officers time.

Product Overview
Smart RF Monitoring System The SMART® RF Home Curfew Monitoring system utilizes Pro Tech's state-of-the-art technology as an effective curfew compliance tool at an affordable price. The SMART® RF System is designed specifically for offender monitoring and is proven to be versatile, reliable and tamper resistant.

SMART® RF utilizes Pro Tech's ankle transmitter together with the proven Base Unit. Offenders are fitted with a tamper-resistant ankle bracelet and assigned a Base Unit that is placed in the offender's residence. The Base Unit provides a detailed recording of all leaves and enters, as well as tamper detection, phone line and power monitoring. The SMART® RF System notifies supervising officers of any unauthorized events, including curfew and bracelet violations. The Base Unit calls Pro Tech's Surveillance Data Center (SDC) via a landline connection approximately every six hours or whenever a violation has been detected. This information can be accessed at any time by utilizing Pro Tech's acclaimed PCE software and a secure Internet connection.

Easy to Use , Easy to Track
The SMART® RF Home Curfew Monitoring System generates alerts as desired, on either a real-time basis or as next-day reporting. Each supervising officer receives a Daily Violation Summary Report (DVSR) via email, providing a detailed record of activity for all offenders making the system extremely user-friendly.

The SMART® RF Home Curfew Monitoring System delivers the unique flexibility of selecting the supervision level that is appropriate for the offender. The offender may be switched from SMART® RF to SMART® Passive or SMART® Active tracking by simply assigning a tracking device to the offender. No changes are required to the Base Unit or the ankle bracelet, and the same software interface is used for all supervision levels. The versatility of the SMART® System makes it the one system that meets every supervision need without additional training or time-consuming equipment changes.
