Occupational Health Screening and Worker Fatigue Monitoring
Screen your frontline workers before every shift without wearables, clinics, or wait times. Circadify uses contactless rPPG technology to capture heart rate, HRV, fatigue indicators, and stress levels in 30 seconds flat — helping EHS teams flag fitness-for-duty concerns before workers reach the floor.
Why Choose Us
Advanced rPPG technology that transforms any camera into a health monitoring device
Pre-Shift Heart Rate Screening
Capture resting heart rate as a baseline fitness-for-duty indicator before every shift. Circadify detects blood flow patterns through facial video analysis, flagging elevated BPM that may signal fatigue, illness, or impairment before a worker enters a hazardous environment.
Fatigue and Recovery Detection
Heart rate variability is a leading indicator of fatigue and inadequate recovery. Circadify measures HRV at the gate, giving safety managers objective data on whether a worker's autonomic nervous system shows signs of sleep deprivation or cumulative fatigue.
Heat Stress and SpO2 Monitoring
Estimate blood oxygen saturation as part of every pre-shift check. For workers in confined spaces, high-altitude sites, or extreme heat environments, SpO2 screening helps identify respiratory risk factors before they become on-site emergencies.
Physiological Stress Scoring
Quantify each worker's stress state from multiple biomarkers in a single scan. Elevated physiological stress correlates with impaired reaction time and decision-making — critical factors in safety-sensitive roles from heavy equipment operation to chemical handling.
Simultaneous Multi-Metric Capture
All indicators measured at once, not sequentially. Parallel processing algorithms extract every metric from the same 30-second scan, keeping screening lines moving and minimizing disruption to shift start times.
On-Device Processing for Worker Privacy
All vitals screening processes entirely on the device. No biometric video data leaves the phone, protecting worker privacy while still delivering actionable fitness-for-duty signals to your EHS dashboard.
Integrate Contactless Screening Into Your Safety Program
Replace subjective fitness-for-duty checks with objective physiological data.

Pre-Shift Fitness-for-Duty Screening
Screen every worker before they enter a hazardous environment. Circadify delivers objective vitals data at the gate — heart rate, HRV, SpO2, and stress — giving supervisors the information they need to make informed fitness-for-duty decisions without invasive testing.
Gate-level screeningFatigue Risk Management Systems
Layer contactless vitals into your fatigue risk management program. HRV trends across shifts reveal cumulative fatigue patterns, enabling proactive scheduling adjustments before impairment leads to incidents on the shop floor or job site.
Fatigue pattern analyticsHeat Stress and Environmental Monitoring
Pair SpO2 and heart rate screening with environmental data to identify workers at elevated risk during extreme heat events, confined space entry, or high-altitude operations. Contactless checks enable rapid re-screening throughout a shift without pulling workers off task.
