Why is my face not being detected? - Talview Docs

During an assessment, Talview uses facial recognition to verify your identity through your camera. If you see a “Face not detected” message, this checklist helps you resolve common lighting, positioning, and camera-related issues.

🔎 Troubleshooting Common Issues

What might be wrong	How to fix it
Poor lighting conditions	Position yourself in a well-lit area with light shining on your face from the front. Use natural light or add a lamp behind your screen pointed toward you. Avoid overhead-only lights that create shadows under your eyes or nose.
Backlighting creates shadows	Never sit with your back to windows or bright light sources, this makes your face appear dark. Turn your setup so the light faces you directly, not from behind.
Camera positioned incorrectly	Place your webcam at eye level and center your face in the frame. Maintain an arm’s length distance so your full face is clearly visible without excessive zoom. Adjust the angle to avoid looking up or down.
Face obstructed or covered	Remove hats, sunglasses, masks, scarves, or anything covering your face (unless required for religious or medical reasons). Ensure your entire face from forehead to chin is visible.
Glasses causing glare	Adjust your position or tilt your glasses slightly to minimize reflections from lighting sources. If glare persists, try repositioning your light source or camera angle.
Multiple faces in frame	Ensure you’re alone in the camera view, no other people, photos, or posters with faces should be visible. Only your face should appear in the frame.
Camera hardware issues	Test your webcam in another application (like your device’s camera app) to confirm it’s working. Clean the lens with a soft cloth to remove dust or smudges. Close other apps using the camera (Skype, Zoom, Teams).
Neutral background missing	Use a plain, well-lit background (white or neutral colors work best). Avoid busy patterns, bright colors, or cluttered areas that might confuse the detection system.

Additional Troubleshooting Tips

Test your webcam functionality by opening any video application to confirm the camera is working properly
Clean the webcam lens, as dust or smudges can blur the image and affect detection
Close all applications that might be using the camera, such as Skype, Zoom, or Teams, as they can interfere with the assessment platform
Ensure adequate lighting in the room for optimal video quality
If using an external camera, ensure it is properly connected to your computer with cables securely plugged in
