How this test works
Preview your webcam securely in the browser with no upload. The test uses standard browser capabilities and does not require installing an application.
When to use it
- Before buying a used or refurbished laptop.
- When troubleshooting a device after a repair or update.
- Before selling or handing a device to someone else.
Important limitations
A website cannot fully diagnose every hardware component. Treat the result as a practical screening check. For faults that matter financially or affect safety, use operating-system diagnostics or a qualified repair technician.
Frequently asked questions
Is my camera video uploaded?
No. The preview is displayed locally in your browser unless you separately choose to share it elsewhere.
Why does the site ask for permission?
