Quick answer
What Browser Permission Checker tells you
Review the browser-visible state of camera and microphone permissions without requesting access on page load.
- Observed here
- Camera permission state, Microphone permission state, Secure-context status.
- How to interpret it
- Permission states reflect what the browser exposes for this origin. An unsupported permission query is not a denial, and a granted state does not guarantee an available camera or microphone stream.
- Important limit
- Results reflect events and values exposed by this browser.
- Data handling
- Test values are calculated in this browser. Device Test Bench does not store a test result or create a device fingerprint.
Useful next comparison: Review this site in browser permission controls, then deliberately start the relevant media test to check actual access.
Understanding the result
What a result means
The page reports only the permission state the browser is willing to expose without starting a stream. prompt means a decision has not been stored; denied can come from site controls or an operating-system privacy block.
Confirm the pattern by repeating camera permission state. Results reflect events and values exposed by this browser.
How to use this test
- Open the checker.
- Review the current state before making any request.
- Use the separate camera or microphone page to request access.
- Follow browser-specific steps if permission is blocked.
What this test checks
- Camera permission state
- Microphone permission state
- Secure-context status
- MediaDevices availability
What this test cannot check
Results reflect events and values exposed by this browser.
This test does not certify hardware or replace professional inspection.
Some browsers report permission state only after a request.
Common problems and troubleshooting
Open the site information panel to change a stored decision, then reload. When the state is unavailable, use the dedicated camera or microphone page for a deliberate request and compare operating-system privacy settings.
- Repeat the same observation. Focus the test surface and repeat “Camera permission state” three times under the same conditions.
- Change one condition. Compare “Microphone permission state” after changing only the relevant port, connection, browser setting or application.
- Rule out focus or interception. Close overlays and reserved shortcuts, keep the page visible and confirm that the live indicator changes during the action.
- Keep the result within its limit. Results reflect events and values exposed by this browser.
If the same pattern remains across relevant applications and connections, give the manufacturer or a qualified technician the repeatable observations instead of a guessed fault label.
Browser compatibility
The Permissions API does not expose camera and microphone state consistently in every browser, especially Safari. An unavailable query is shown honestly and is not treated as permission granted or denied.

Yes. The test works without an account, download or payment.
Is my test data uploaded?
Test values are calculated in this browser. Device Test Bench does not store a test result or create a device fingerprint.
