If your camera doesn't work in Teams: first check if Teams has camera access — click your profile picture > Settings > Devices and select your camera from the dropdown. If it says "No camera found," close other apps using the camera (Zoom, FaceTime). On Windows, go to Settings > Privacy & security > Camera and make sure Microsoft Teams is allowed. On Mac, check System Settings > Privacy & Security > Camera. Update Teams to the latest version (click the three dots > Check for updates). If using the web version of Teams in Chrome, check chrome://settings/content/camera permissions. Restart Teams after changing any permissions. For external webcams, unplug and replug the USB cable. If Teams freezes on the camera, try turning off background effects which are CPU-intensive.
