OptiGuard™

In-Cell Biometric Awareness with No Wearable Required

A Unified Correctional Biometric Platform

In today’s correctional environment, agencies are expected to demonstrate proactive monitoring practices and enhanced oversight, not just reactive responses. Continuous biometric awareness provides earlier situational insight, faster intervention capability, and defensible documentation when incidents are scrutinized.

4Sight Labs develops biometric monitoring solutions built exclusively for correctional and custody settings. We are advancing safety and welfare in high-risk custody operations.

Continuous Monitoring in High-Risk Custody

OptiGuard™ extends 4Sight Labs’ Unified Correctional Biometric Platform into the cell environment. It transforms existing detention camera systems into an automated liveness monitoring layer.

OptiGuard has been live in active detentions environments since early 2026. See how it can integrate with your existing infrastructure and strengthen your facility. It strengthens observation protocols by providing continuous automated liveness detection between physical checks. It does not replace officer rounds, it enhances them.

Liveness Detection Using Existing Camera Infrastructure

Using advanced video-based analytics, the system detects:

  • Breathing patterns
  • Subtle physiological movement
  • Changes in motion consistent with safety and welfare risk

OptiGuard™ Seamless Integration

Designed for rapid, standards-based deployment, OptiGuard™ integrates with existing IP camera infrastructure through a dedicated on-premise appliance operating within the agency's secured network. This is infrastructure-aware technology.

movement detection
The subject is outlined in green, indicating the system has identified a person within the camera frame. Because the subject is standing and moving within the cell, OptiGuard recognizes full-body motion and classifies the activity as movement detected.
localized motion detection
The green outline identifies the subject within the cell, while the red highlighted region indicates localized motion detected by the system. Even though the subject’s body appears mostly still, OptiGuard identifies subtle movement within specific areas.
Breathing Pattern Detection
The green outline identifies the subject, while the yellow markers represent subtle breathing-related motion detected by the algorithm. Even when the subject appears completely still to the naked eye, OptiGuard can detect these micro-movements that indicate physiological presence.

Fast and Reliable Liveness Detection Algorithm

A dedicated on-premise appliance processes video locally within the agency's secure network. There is no cloud video storage and no disruption to existing systems.

Layered Biometric Protection

OptiGuard™ is the environmental monitoring layer within 4Sight Labs' Unified Correctional Biometric Platform. When paired with OverWatch®, agencies can confidently implement a layered standard for safety and welfare.

OptiGuard™ — Environmental Awareness
  • Breathing and movement detection

  • No wearable required

  • Ideal for high-risk, single-occupancy cells

OverWatch® — Individual Physiological Monitoring
  • Continuous physiological monitoring

  • Automated notifications when safety thresholds are exceeded

Unified Biometric Awareness for Modern Custody Environments

OptiGuard™ extends biometric monitoring beyond the individual, transforming the detention environment into an active layer of awareness within 4Sight Labs’ unified biometric platform.

Environmental Awareness & Individual Monitoring
OptiGuard™ when combined with OverWatch®, provides agencies with continuous awareness of both the cell environment and the individual detainee.

Continuous Biometric Awareness Matters
Continuous biometric awareness helps agencies identify potential safety and welfare risks earlier, and facilities gain greater situational insight and faster response capability.

Common questions

OverWatch® and OptiGuard™ strengthen safety and welfare oversight where it matters most.

No. OptiGuard™ is designed to enhance observation protocols, not replace them. The system provides continuous automated liveness monitoring between physical checks by detecting breathing patterns and subtle physiological movement through existing camera feeds. This added layer of awareness helps agencies maintain stronger oversight between scheduled rounds.

No. OptiGuard™ is designed to work with existing IP camera infrastructure. The system receives a live RTSP video feed from current cameras and processes it through a dedicated on-premise appliance deployed within the agency’s secure network. No modifications to camera hardware, firmware, or existing video management systems (VMS) are required.

No. Video processing occurs locally through a dedicated on-premise appliance operating within the agency’s secured network. The system analyzes video feeds for breathing and movement patterns without requiring cloud video storage, helping agencies maintain control over their data and infrastructure.

OptiGuard™ is specifically designed for high-risk, single-occupancy housing environments, including medical observation cells or other areas where enhanced monitoring is required. It provides automated liveness awareness without requiring detainees to wear biometric sensors.

Together, these systems extend biometric awareness from the individual to the environment, strengthening response capability, documentation integrity, and litigation defensibility in high-risk custody settings.

OptiGuard™ serves as the environmental monitoring layer within 4Sight Labs’ Unified Correctional Biometric Platform. When paired with OverWatch®, agencies gain two complementary monitoring capabilities:

  • OptiGuard™ monitors breathing and movement within the cell environment using camera analytics.
  • OverWatch® provides continuous physiological monitoring of the individual detainee through wearable biometric sensors.

Together, these systems extend biometric awareness from the individual to the environment, strengthening response capability and documentation in high-risk custody settings.
