Digital Camera diagnostics

Test what the browser can see. Know when it cannot.

Use DeviceOK for webcam/USB/storage-adjacent checks when the camera exposes them, then continue with the camera maker's own diagnostics and media-card guidance.

First diagnostic sequence

Do the high-signal checks before risky changes

  1. 1

    Confirm battery and memory-card state

  2. 2

    Test the camera's own playback/menu functions

  3. 3

    Use webcam-mode tests only if the camera explicitly supports that connection mode

What DeviceOK/browser can help check
  • Test live video if the camera exposes a browser-visible webcam stream
  • Provide focus and exposure reference targets
  • Estimate media transfer time
What this browser page cannot prove
  • Read shutter count generically
  • Inspect sensor electronics
  • Diagnose lens mechanics or camera firmware
