The browser can see the camera
The test requests the rear camera where available, then reports the actual resolution and frame rate returned by the browser.

No-upload camera preflight
Test the device before the bike is waiting.
Find permission, camera, light or pose-model problems now — before you move furniture, mount the bike and start pedalling. The test uses a temporary live preview, performs no recording and uploads no camera frames.
- One deliberate camera prompt
- Real settings, not device claims
- Stream stops after the test
Local device preflight
Know the camera will work before you set up the bike.
One deliberate permission request checks the real camera, usable light and the same on-device pose runtime used by Capture Director. No clip is recorded or uploaded.

Browser does not expose permission status
The preview exists only in this tab. The temporary storage probe is deleted as soon as it passes.
No camera frames leave this tab
Your real preview appears here only after you press the button.
No automatic prompt. No recording. No cloud fallback.
What the result proves
A preflight, not a fit score.
The scene has usable light
Ten tiny in-memory samples use the same 40–245 luminance window as the later capture-quality gate. They are discarded immediately.
The local analysis runtime loads
The exact MediaPipe pose engine used by Capture Director is initialized on this device. A failed load is surfaced before recording, never hidden behind a frame upload.
After the green light
The camera is ready. The physical protocol still matters.
Readiness means the device can run the workflow. It does not mean the phone is level, the whole rider is framed or a movement result is trustworthy — those checks happen during capture.
- 1Fix the phone
Use a stable support; never hold it while recording.
- 2Square the view
Keep the lens level and exactly side-on to the bike.
- 3Fit the whole system
Show the rider, both wheels and the complete pedal stroke.
- 4Repeat before acting
A result needs clean cycles and an independent re-check.
