Webcam not detected

Problem summary

A missing webcam is often caused by privacy permissions, a bad USB path, another app holding the camera, or stale drivers.

When to worry

• No app can see the camera.
• The camera light turns on but no image appears.
• The webcam works on another computer but not this one.

Fast checks

• Close video meeting apps and reopen only one test app.
• Check OS camera privacy permissions.
• Plug the webcam directly into the computer instead of a dock or hub.
• Try a different USB port and cable if detachable.

Likely causes

• Camera access is blocked by privacy settings.
• Another app is holding the camera.
• A dock, hub, or cable is not passing enough data or power.
• The webcam driver or firmware is stale.

Step-by-step fix

1. 1Open the OS camera app to test outside the meeting app.
2. 2Allow camera access for the specific app.
3. 3Disconnect and reconnect the webcam directly to the computer.
4. 4Restart the computer once if the camera is stuck in use.
5. 5Update the webcam software only from the manufacturer or OS update channel.

What not to do

• Do not install random driver updater tools.
• Do not assume the meeting app is broken until the OS camera app is tested.
• Do not keep a loose cable or damaged privacy cover in place.

When to stop/get help

• Stop if the webcam is physically damaged or gets hot.
• Stop if a work-managed computer blocks camera access by policy.
• Get help if device manager or system profile shows hardware errors after direct connection.
