Test your webcam before Zoom in two ways. The fastest method is to open an online webcam test — you'll see a live preview of your camera with resolution and FPS info, which tells you exactly what others will see. Alternatively, use Zoom's built-in test: open Zoom, click your profile picture, go to Settings > Video, and you'll see a camera preview. You can switch cameras from the dropdown if you have multiple. Check that the image isn't too dark (add a light source facing you), isn't blurry (clean the lens), and shows the right camera (not a virtual camera). Do this 2-3 minutes before your meeting so you have time to fix any issues.
