Face Detection Demo

Detect faces live from your webcam and try simple liveness prompts — blink, turn your head, smile. A demo only, never authentication.

Face Detection Demo — detect faces live in your browser with a webcam liveness demo that never uploads any frame at all.

How to use Face Detection Demo

Click Start webcam demo and allow camera access when your browser asks.
Face the camera — the detector draws a bounding box and confidence score around each face it finds.
Work through the liveness prompts in order: blink, turn head left, turn head right, smile.
Use Check this prompt on the active prompt to record a pass or fail for that demo check.
If you have no camera or deny access, open the no-camera explainer to see how the demo works step by step.
