How Contactless Screening Works on Your Site
From smartphone deployment to actionable fitness-for-duty data — pre-shift screening in four steps
Simple steps to get started
Install Circadify on smartphones or tablets at gate stations, break rooms, or supervisor checkpoints. No specialized hardware procurement, no calibration — screening capability is ready as soon as the app is installed.
At shift start, each worker faces the device camera for 30 seconds. Good lighting is the only requirement. The contactless approach eliminates hygiene concerns from shared equipment and speeds throughput at busy shift changes.
The on-device rPPG engine simultaneously extracts heart rate, heart rate variability, estimated SpO2, and physiological stress index from the facial video. All processing happens locally — no biometric data leaves the device.
Results are available immediately. Supervisors see actionable screening data — flagged indicators, trend comparisons against baseline, and fatigue risk signals — enabling informed decisions before workers enter safety-critical environments.
