Questions About Occupational Health Screening

Workers face a smartphone camera for 30 seconds at the start of their shift. The rPPG engine analyzes the facial video to extract heart rate, HRV, SpO2 estimation, and a physiological stress index. These indicators are delivered to the supervisor or EHS dashboard as objective data points to inform fitness-for-duty decisions — no wearables, no medical devices, no physical contact required.

Every 30-second scan captures four categories: resting heart rate (BPM), heart rate variability (HRV — the leading objective fatigue indicator), estimated blood oxygen saturation (SpO2), and a composite physiological stress index. Together, these provide a comprehensive picture of a worker's readiness for safety-critical tasks.

Contactless screening generates objective physiological data that layers into your existing safety management system. The data supports fatigue risk management programs, heat illness prevention plans, and fitness-for-duty protocols. It does not replace medical evaluations — it provides pre-shift screening data that helps safety managers identify workers who may need further assessment.

Contactless vitals screening is designed as a rapid pre-shift screening layer, not a replacement for comprehensive medical evaluations. It provides objective physiological indicators that can flag potential concerns and inform decisions about whether a worker should proceed to a full evaluation. Think of it as a first-pass filter that scales across your entire workforce every shift.

All biometric processing happens on the device itself. No facial video data is transmitted to the cloud or stored on external servers. The system outputs only numerical vitals data, not biometric imagery. This on-device architecture supports compliance with biometric privacy regulations and addresses union concerns about surveillance.

Deployment requires only smartphones or tablets — no specialized hardware procurement, no calibration, no installation crews. Install the app on site devices and screening is operational. Multi-site rollouts that would take months with traditional equipment can begin within days, scaling from a single gate station to hundreds of checkpoints.
