Trak3 (Two-Piece Tracker)


Allied Universal® Electronic Monitoring’s Two-Piece GPS Tracking Unit provides precision location for continuous monitoring. A transmitter worn by the monitored person sends signals to the Two-Piece unit to verify their proximity to the tracking unit. Location data processed and stored by the Two-Piece unit is transferred over the cellular network or Wi-Fi networks using an encrypted protocol. The unit stores program configuration details, reporting events according to the participant's personal schedule and geo-zone restrictions. Bi-directional voice communication enables contact with the monitored person at any time.

Advanced Location Technology

The Two-Piece GPS device incorporates a new-generation integrated GPS module providing highly accurate location capabilities. This is coupled with Wi-Fi location and triangulated cellular Location Based Service (LBS) as backup location methods.

Convenient Mapping Tools

Allied Universal® Electronic Monitoring's Chronos System provides a Web-based, operator-friendly interface for viewing location trails, device status, events and violation conditions. A wide range of reporting features are also available.


Reliable communication

Encrypted data transfer to the monitoring center, bi-directional voice communication with the participant and simultaneous voice and data over the cellular network.

Advanced tracking methods

Leveraging multiple satellites systems (supported by GPS, GLONASS, Galileo, and BeiDuo), Wi-Fi tracking, and Tower Based Tracking the TRACK3 is meticulously designed to provide a location in the most challenging locations.

Flexible program configuration

Scheduling and zone configuration options to meet the monitoring needs of each agency and monitored individual. Customizable local indication (visual, audible and vibration), call intervals and GPS sampling rates.

Tamper protected solution

Multiple detection mechanisms on the Two-Piece GPS unit and the participant's body-worn transmitter provide electronic and physical evidence of tamper attempts.

Multi-language support

The device status display and menu interface is available in a wide range of languages per customer requirement.

Optional home beacon
