Tool
Camera test
Ten seconds before the call. Your video stays on this page — nothing is recorded or uploaded.
Press start, allow the browser prompt, and look at yourself. This is the same check the VirtualCam extension runs in its Test tab, in web form.
The preview appears here. Nothing leaves this page.
Reading the result
- Live preview — the camera works and the browser trusts the site. You are set for calls.
- “Permission denied” — the browser blocked camera access; check the camera icon in the address bar and the OS camera settings.
- “No camera found” — the classic. Either no device is present or another app is holding it. This is exactly what VirtualCam’s Blank Screen and Phone modes are for.
- Black preview — the device answers but renders nothing (a driver or privacy shutter issue).
If there is no camera at all
That is the situation VirtualCam was built for: use your phone as the camera, or set a clean generated feed — both free, both direct from your devices.
