Camera Tests

Local browser camera tools for webcam access and preview, camera selection, browser-reported stream settings, snapshots, and an on-page mirror.

Common problems and tasks

Choose the right path

Webcam diagnostics inspect access, preview, settings, cadence, and snapshots; Online Mirror is a simpler appearance check.

Camera setup

Choose the right camera tool

Use Webcam Test when you need to check camera access and browser-reported video information. Use Online Mirror when you mainly want a flexible self-view.

Webcam TestDeliberately open one preferred camera, confirm the browser-selected source, inspect negotiated track settings, decoded frame size, observed preview cadence and capability ranges where supported, then record a bounded visual observation or local unmirrored snapshot. It does not certify sensor specifications, camera health, image quality, latency, or autofocus.Online MirrorUse a local camera mirror with camera selection, mirrored or unmirrored view, fit/fill, zoom, brightness, 0/90/180/270 rotation, freeze/resume, and fullscreen. These are on-page display transforms; they do not modify camera hardware, firmware, lens, sensor, exposure hardware, or actual source-camera settings.

Two camera jobs

Diagnostics or a flexible self-view?

Webcam diagnostics

Webcam Test is the camera-access and browser-state task: choose the device, inspect the stream and reported video settings, decoded preview dimensions, delivered-frame cadence, and capability ranges, then record a snapshot or visual observation for that run.

Online mirror view

Online Mirror is the flexible self-view task: adjust presentation with zoom, brightness, rotation, fit/fill, mirroring, freeze, and fullscreen without claiming to change the camera itself.

Better checks

Run a clean camera check

  1. Grant access and choose the intended camera

    Start the dedicated tool and grant camera permission only when the browser asks. If multiple cameras are exposed, select the camera you intend to inspect. Permission is not proof that the camera is healthy, and a listed device is not proof that its hardware fully works.

  2. Check the preview under consistent conditions

    In Webcam Test, check the intended camera, preview, framing, clarity, lighting, motion, browser-negotiated track settings, decoded frame size, and observed preview cadence where supported. For comparisons, keep the same camera, browser, lighting, connection, and relevant OS or browser camera settings. Online Mirror brightness, zoom, and rotation change only the preview display, not camera hardware quality.

  3. Change one variable and repeat

    For a black or wrong-camera preview, unexpected dimensions or FPS, blurry or dark image, or an interrupted stream, change one relevant condition—selected camera, browser permission, browser, USB port or cable, lighting, OS camera setting, or a competing camera app—and retry before concluding the hardware failed.

Webcam diagnostics

Webcam Test shows one explicit capture run, the selected and actual browser-exposed camera, negotiated track settings, decoded preview dimensions, delivered-frame cadence where supported, and capability ranges. These are not a factory sensor certificate, guaranteed maximum resolution, laboratory frame-rate certification, formal image-quality calibration, or camera health certificate. Clear, blurry, dark, bright, flicker, uneven, and no-image choices are user observations, not automatic defect classification.

Online mirror view

Online Mirror uses the same browser camera stream for self-view. Mirror, fit/fill, zoom, brightness, and rotation only change page presentation. They cannot prove or modify physical camera orientation, lens, sensor exposure, firmware, hardware zoom, or camera calibration.

Local by default

Preview and snapshot handling stay local to the browser. Camera tools do not automatically record or upload your video.
