How is the system different from consumer wearable monitoring technologies?

The system was not adapted from consumer fitness technology. It was purpose-built for correctional infrastructure, operating reliably in steel-reinforced facilities where communication integrity, documentation defensibility, and operational accountability are non-negotiable.

How Deployment Works

There’s a clear path to get your facility fully covered with 4Sight Labs. No surprises, no guesswork about what happens next.

We pinpoint the documentation gaps putting your agency at risk.

Sensors are enrolled, including for higher-risk detox and withdrawal cases.

Your plan closes the monitoring gaps staff can't watch alone.

Continuous awareness goes live, closing the gap in coverage.

Infrastructure goes in for continuous awareness, no extra work for staff.

Ongoing support keeps documentation defensible and coverage running.

Staff train hands-on, so every record holds up to review.

We check in regularly to confirm the system is solving the problems it was brought in for.

About 4Sight Labs

All biometric data is encrypted during transmission and storage. The OverWatch® platform is hosted within Microsoft Azure Government (Azure Gov), configured to support HIPAA-compliant safeguards. 4Sight Labs maintains SOC 2 certification, reinforcing enterprise-grade security controls, access governance, and audit integrity.

OverWatch® hardware is engineered for custodial durability, including a 250 lb pull-strength band designed to resist tampering. System notifications reach staff if device integrity or battery status requires attention.

Yes. Our unified platform is designed to integrate with existing facility management and record systems, reducing manual workflows and supporting unified operational oversight.

OverWatch is engineered specifically for correctional environments, providing continuous monitoring of wearable sensor signals associated with safety and welfare issues among individuals in custody. Unlike consumer wearables designed for personal wellness and fitness, OverWatch is built for facility-wide deployment, secure data transmission, correctional workflows, and timely staff notification. It's designed to give staff actionable information that supports observation and response, not to diagnose or treat medical conditions.

The platform operates on a hardened, correctional-grade communication architecture engineered for dense detention environments. Unlike short-range or consumer-based connectivity models, it maintains dependable signal integrity and continuous data transmission across complex, distributed facility layouts.
