Simple Enrollment and Installation

Custom program configuration allows specific rules, schedules, and zones to be set for each participant. Quick and simple installation provides a custom secure fit for each participant. Activates in less than 5 minutes.

Onboard Processing

The XT stores the participant’s rules onboard and compares its location to the rules defined for the participant. By doing so, the device can notify participants and generate alerts for noncompliance faster than devices that do not have this capability.

Pursuit Mode

Pursuit Mode enables the Attenti system to go into real-time tracking. It accelerates the speed at which the XT reports into EM Manager, allowing officers to closely track the offender’s locations during an active investigation.

Optional Home Curfew Base Unit

Effective home curfew monitoring improves location accuracy while allowing offenders to move freely indoors. Reports on violations via landline if the cellular signal is lost indoors.


The XT encompasses multiple technologies for communicating with participants in real time: two-way voice communication, text messaging, LED lights, vibrations, and audible alerts.
