High-Security Tamper-Proof GPS Ankle Monitor

Electronic Ankle Monitor (TR40) is a lightweight, waterproof tracking device designed for electronic ankle monitoring. It integrates GPS and Wi-Fi positioning with 4G connectivity for real-time location tracking. Key features include geofencing (electronic fence) , tamper-proof design, and instant tamper alerts to ensure supervision integrity.

The TR40 supports TCP and MQTT communication protocols with TLS encryption for secure data transmission. It offers dual encryption options—ChaCha20-Poly1305 and AES—ensuring data security and compliance with modern safety standards.

Ideal for pretrial monitoring, bail monitoring, community corrections, home arrest, and wander monitoring, the TR40 provides reliable supervision for offenders, probationers, and vulnerable populations in law enforcement and elderly care settings.

Monitoring Applications

Pretrial Monitoring

Support defendants awaiting trial with GPS smartwatches that monitor locations and enforce court-ordered conditions. Real-time violation alerts enhance public safety while allowing individuals to remain in the community..

Community Corrections

Monitor offenders in community programs with GPS tracking that enforces curfews, sets exclusion zones, and reports violations. Smartwatches support rehabilitation while ensuring public safety.

Home Arrest

Enforce home arrest conditions with reliable GPS monitoring that tracks location, sets virtual boundaries, and provides instant violation alerts. Smartwatches enable secure, remote supervision.

Witness Management

Protect witnesses with GPS smartwatches that offer discreet location tracking, emergency alerts, and secure communication. They enhance safety and confidence during legal proceedings.

Bail Monitoring

Ensure bail compliance through GPS smartwatches that track movements, enforce curfews, and alert authorities of any breaches. They offer a cost-effective alternative to detention.

Technical details about TR40

The Electronic Ankle Monitor from Thinkrace is a sophisticated wearable device engineered for durability and precision in offender supervision. It features multi-mode positioning technology, integrating GPS (Global Positioning System) , GLONASS, Wi-Fi, and LBS (Base Station) positioning to ensure accurate location tracking both indoors and outdoors. The device is equipped with reliable communication modules to guarantee real-time data transmission. It includes a high-capacity, long-lasting battery designed for 24/7 continuous operation, often lasting several days on a single charge. The unit is built with an IP67/IP68 waterproof and dustproof casing to withstand harsh weather conditions and daily wear. Essential sensors include an accelerometer for movement detection and a tamper sensor with anti-removal detection to immediately identify any attempt to cut, break, or force open the strap.

This device is designed to go beyond simple tracking, offering a robust suite of security features for judicial supervision:

Real-Time GPS Tracking: Provides continuous, real-time location data of the wearer, allowing supervisors to monitor movements on a digital map.
Geo-fencing (Electronic Fence): Operators can set up virtual boundaries. If the wearer enters a restricted area or leaves a permitted zone, the system immediately sends an automated alert.
Intelligent Tamper Alerts: The monitor features a sophisticated anti-tampering mechanism. If the strap is cut, broken, or forced open, an immediate alert is triggered to the monitoring center, preventing unauthorized removal and ensuring compliance.
Historical Location Playback: Supervisors can review the wearer’s movement history over a specific period to analyze patterns or verify compliance with curfews and restrictions.
Movement Analysis: The built-in accelerometer detects the wearer’s activity level and can identify unusual patterns, confirming the device is being worn by a live subject.

The Electronic Ankle Monitor is specifically designed for the judicial and law enforcement sectors:
