Media Device Checker

Device labels and complete enumeration can remain hidden until permission is granted; absence from a pre-permission list does not prove the hardware is missing.

Browsers often hide device labels until permission is granted. Device IDs can also change between sessions or privacy contexts.

What the browser can measure

Start with a functional check, measure only what the browser can actually expose, then retest after one change.

ConnectChoose the actual browser-visible device or grant permission when required.

TestConfirm basic signal, input, output, preview or display behavior.

MeasureUse browser-exposed levels, timing, resolution, FPS, axes or event data.

DiagnoseCompare the symptom with the specific diagnostic instead of relying on one number.

RetestRepeat after changing the device, cable, permission, browser or system setting.

Browser boundary
These tools observe browser APIs and local media/event streams. They cannot certify hardware condition, bypass denied permissions, or expose measurements the browser/OS does not provide.

Device inventory, label coverage & grouping evidence

Enumerate the browser-visible audio/video endpoints, optionally request permission for labels, and export a local device inventory without treating browser IDs as permanent hardware serials.

What this tool checks

List browser-visible audio/video devices and media capabilities with explicit permission boundaries.

How to use the result

Device labels and complete enumeration can remain hidden until permission is granted; absence from a pre-permission list does not prove the hardware is missing.

Privacy & browser limits

Device streams and input events used by this page are handled in your browser unless the page explicitly says otherwise. Permission, label, timing and hardware-field availability depend on the browser and operating system.

Media enumeration is safer and permission-aware

Secure-context/API availability and camera/microphone permission states are reviewed. Device IDs are masked by default and only revealed after an explicit user choice.
