REFINE Technology is proud to announce the successful deployment of CO-EYE electronic monitoring devices at the Mawei District Bureau of Justice in Fuzhou, Fujian Province, China. The deployment supports Mawei District’s implementation of tiered classification management (分级分类管理) for community corrections subjects — a national policy mandate from China’s Ministry of Justice designed to match supervision intensity with individual risk levels.

Tiered Classification: Matching Technology to Risk

Under China’s Community Corrections Law (《社区矫正法》), enacted in 2020, and its implementing regulations, local judicial agencies are required to classify community corrections subjects into strict supervision (严管), standard supervision (普管), and relaxed supervision (宽管) tiers. Each tier carries different reporting frequencies, educational requirements, and — crucially — different levels of electronic monitoring.

For Mawei District, this meant deploying two distinct device categories to serve two distinct supervision needs:

• CO-EYE ONE GPS Ankle Monitor — assigned to strict supervision subjects who require continuous GPS location tracking, real-time geofence alerts, and tamper-proof monitoring with fiber-optic anti-tamper detection.
• CO-EYE BLE i-Bracelet — assigned to standard supervision subjects who need regular presence verification via Bluetooth Low Energy check-ins, without the full GPS tracking overhead.

This two-tier hardware approach directly addresses the Ministry of Justice’s core principle: supervision intensity must be proportional to risk. High-risk subjects get the full GPS tracking capability of the CO-EYE ONE, while lower-risk subjects wear the lightweight 17-gram i-Bracelet — a device so compact and discreet that it reduces stigma and minimizes disruption to daily life, work, and social reintegration.

Fuzhou Mawei District: Community Corrections at a Glance

Mawei District (马尾区), located in eastern Fuzhou at the mouth of the Min River, is a compact urban-industrial district with a population of approximately 280,000. As a national-level economic development zone, Mawei has a relatively small but diverse community corrections caseload — reflecting the district’s mix of urban professionals, industrial workers, and migrant populations.

The Mawei District Bureau of Justice oversees community corrections through its Community Corrections Management Division and local judicial offices (司法所). Fujian Province has been at the forefront of community corrections informatization in China, with neighboring districts like Cangshan already rolling out three-year smart corrections action plans covering 2024–2026. Mawei’s adoption of CO-EYE’s tiered monitoring solution represents a practical execution of these provincial digitization goals.

Why Two Devices? The Operational Logic Behind Tiered Monitoring

Traditional electronic monitoring programs often deploy a single device type across all supervision tiers — forcing agencies to either over-monitor low-risk subjects (wasting resources and increasing stigma) or under-monitor high-risk subjects (creating public safety gaps). CO-EYE’s product matrix solves this by offering purpose-built hardware for each tier:

CO-EYE ONE for Strict Supervision (严管)

The CO-EYE ONE is a 108-gram one-piece GPS ankle monitor with fiber-optic tamper detection that produces zero false alarms. Key capabilities deployed in Mawei:

• Continuous GPS tracking with sub-2-meter accuracy across GPS, BeiDou, GLONASS, and Galileo constellations
• Real-time geofence enforcement — instant alerts when a subject enters or exits designated zones
• Adaptive multi-mode connectivity — BLE, WiFi, and LTE auto-switching ensures no monitoring gaps in basements, concrete buildings, or rural areas
• 7-day LTE battery life (up to 180 days in BLE mode) — dramatically reducing charger management overhead for officers

CO-EYE BLE i-Bracelet for Standard Supervision (普管)

The CO-EYE BLE i-Bracelet weighs just 17 grams and is designed for subjects who require regular presence verification without continuous GPS tracking. Key capabilities:

• BLE proximity check-in — pairs with the CO-EYE HouseStation or i-Tracker to verify the subject is within the designated location
• 2-year battery life — the device runs for two full years without charging, eliminating all battery management burden
• Ultra-discreet form factor — at 65×22×10mm and 17g, the i-Bracelet resembles a fitness band, significantly reducing social stigma
• FCC certified with IP68 waterproof rating for all-weather, all-condition wear

Unified Monitoring Platform: One Dashboard for All Tiers

Both the CO-EYE ONE and i-Bracelet feed into CO-EYE’s unified monitoring software platform — an enrollee-centric system built on Java, React, and MySQL. This means Mawei District officers manage all supervision tiers from a single dashboard:

• Real-time GPS tracking for strict supervision subjects and BLE presence verification for standard supervision subjects — on the same map interface
• Automated tier-specific alert rules: different geofence, curfew, and check-in parameters for each classification level
• Integrated event management, compliance reporting, and audit trails across all devices
• Mobile officer app (AMManager) for field operations, available on both iOS and Android

This unified approach eliminates the operational complexity of running separate systems for different device types — a common pain point in agencies that source GPS monitors and presence tags from different vendors.

Advancing Community Corrections Informatization in Fujian

The Mawei deployment is part of a broader trend in Fujian Province toward smart, technology-driven community corrections. Fujian’s judicial agencies have been integrating provincial correction platforms, video check-in systems, and — now — tiered electronic monitoring hardware to create a comprehensive digital supervision framework.

For REFINE Technology, the Mawei project demonstrates a key value proposition: a single vendor providing a complete, tiered monitoring solution — from high-security GPS ankle monitors to lightweight BLE presence tags, unified under one software platform. This approach simplifies procurement, reduces training requirements, and ensures seamless data integration across supervision tiers.
