Introduction: Evaluating GPS Monitoring Vendors for Corrections Agencies

When corrections agency procurement officers evaluate GPS ankle monitoring equipment, two vendor names frequently appear in RFPs and bid responses: CO-EYE (from REFINE Technologies) and BI Incorporated, a subsidiary of The GEO Group. Both supply GPS-enabled electronic monitoring devices to government agencies, bail bond companies, and pretrial services programs. Their business models, product architectures, and geographic reach differ significantly — factors that can materially affect total cost of ownership, program flexibility, and long-term scalability.

This article provides an objective comparison of CO-EYE and BI Incorporated GPS monitoring equipment to support informed procurement decisions. We examine company backgrounds, product portfolios, feature specifications, pricing models, and government contract considerations. The goal is to help procurement officers and corrections administrators identify which vendor aligns with their agency’s caseload composition, budget constraints, and operational requirements.

Anti-Tamper Technology

Anti-tamper quality directly impacts monitoring center workload and program credibility. False tamper alerts consume officer time and can erode trust in the system; insufficient tamper detection creates security gaps.

CO-EYE uses optical fiber detection in both the strap and the device case. When the fiber loop is cut or the case is opened, the system generates an alert and preserves physical evidence of tampering. Optical fiber provides deterministic cut/no-cut results — no probability thresholds or environmental variables like dry skin or poor fit that affect heart-rate or capacitive sensors. The dual strap-and-case approach delivers both electronic notification and physical forensic evidence.

BI Incorporated’s LOC8 XT employs multiple tamper technologies: proximity tamper detection, photo-optic sensor, and fiber-optic strap circuitry. BI also includes GPS jamming detection and an accelerometer for motion-based tamper signals. The combination addresses different attack vectors (strap cutting, device removal, GPS spoofing). BI has not publicly disclosed false positive rates or comparative performance data for these technologies.

Procurement officers should request vendor-specific false alert rate data — preferably from third-party audits or pilot programs — when evaluating anti-tamper claims. High false alert volumes disproportionately affect monitoring center staffing costs.

Connectivity

CO-EYE ONE supports 5G-compatible LTE-M, NB-IoT, and GSM networks. LTE-M and NB-IoT consume less power than standard LTE and offer improved building penetration. Multi-carrier support enables deployment in regions where LTE-M or NB-IoT are primary IoT connectivity options. WiFi serves as a secondary communication channel for redundancy. The CO-EYE ONE-AC variant adds eSIM support, allowing carrier switching without physical SIM replacement.

BI LOC8 XT uses LTE cellular technology. BI literature references LTE Cat M1 modem support for future network compatibility. WiFi and cellular location technologies provide indoor and secondary tracking. The power-saving beacon option allows the device to switch to RF monitoring when within range of a home or work beacon, reducing cellular transmission and extending effective battery life in those scenarios.

Agencies planning deployments in rural or structurally challenging environments should verify carrier coverage for their service areas. LTE-M and NB-IoT often deliver better penetration in buildings and underground parking structures than traditional LTE.

Pricing Model Differences

CO-EYE operates primarily as a hardware and software vendor. Agencies purchase devices and licensing for the CO-EYE monitoring platform. They can operate monitoring in-house, use third-party monitoring centers, or outsource to regional service providers. This ownership model suits agencies that want to amortize equipment costs over multiple years, avoid vendor lock-in, and retain flexibility to change monitoring vendors without replacing hardware.

BI Incorporated typically offers a service-bundled model: per-client, per-day fees that include hardware, software, and 24/7 monitoring center support. Contracts are often multi-year with volume discounts. This model transfers capital expenditure to operational expenditure and reduces upfront procurement burden. It can be advantageous for agencies with limited IT staff or those preferring fully outsourced monitoring. The tradeoff is less control over hardware refresh cycles and potential lock-in to BI’s ecosystem.

Total cost of ownership comparisons require agency-specific inputs: caseload size, average supervision duration, charging logistics, device loss and damage rates, and existing staff capacity for monitoring operations. Procurement officers should model both capital-purchase and service-fee scenarios over a 3–5 year horizon.

Government Contract Considerations

BI Incorporated holds extensive government contracts and is deeply embedded in federal, state, and county procurement processes. Agencies familiar with BI’s contract vehicles and GSA Schedule offerings may find procurement administration straightforward. BI’s 40+ years of US market presence and integration with court and corrections workflows can reduce implementation risk for traditional government buyers.

CO-EYE’s global deployment (200,000+ devices in 30+ countries) includes government and commercial programs outside the US. Agencies considering CO-EYE should verify GSA Schedule status, state contract availability, and compliance with jurisdiction-specific procurement rules. REFINE Technologies has supplied equipment to agencies in Asia, Europe, and other regions; US government procurement experience varies by jurisdiction.

RFPs should specify requirements for: data sovereignty and cloud hosting location; NIJ compliance and emergency removal standards; accessibility and ADA considerations; and integration with existing case management or court systems. Both vendors support standard integration patterns; specific API or integration capabilities should be confirmed during the evaluation phase.

Who Should Choose What

CO-EYE may be a better fit when:

• Your agency prefers to own hardware and avoid long-term service contracts
• Extended battery life (7 days standalone, up to 6 months BLE-connected) reduces charging logistics for high-volume programs
• Sub-3-second installation and compact form factor (108g, 60×58×24mm) matter for officer efficiency and offender compliance
• You need multi-constellation GPS, <2m accuracy, and LTE-M/NB-IoT for challenging coverage environments
• Optical fiber anti-tamper with physical evidence is a priority for reducing false alerts
• International deployment or multi-country programs are in scope

BI Incorporated may be a better fit when:

• Your agency prefers fully bundled monitoring services with 24/7 call center support
• Existing BI contracts, GSA Schedule, or state contract vehicles simplify procurement
• Integration with BI TotalAccess® and Google Maps Platform® is already established in your jurisdiction
• The power-saving beacon option for home/work monitoring aligns with your caseload mix
• Built-in officer-to-client voice communication is required
• US-centric deployment with preference for the largest domestic EM provider

Many agencies operate mixed fleets: BI or another incumbent for existing contracts, and CO-EYE or other vendors for new programs, pilot deployments, or specialized use cases such as domestic violence exclusion zones where battery life and tamper evidence are critical. Procurement decisions should align with your agency’s risk profile, budget cycle, and operational constraints.
