Browser device permissions: camera, microphone and powerful hardware APIs

Modern web platforms gate sensitive capabilities behind user permission, policy or explicit device-selection steps rather than allowing websites to silently scan hardware.

Why it matters

How this changes a diagnosis

A denied permission can look exactly like a hardware failure to an uncareful tool. DeviceOK records permission state separately from device detection and signal state.

Key points

What to remember

  • Permission denied is evidence about access, not proof of broken hardware.
  • Powerful APIs can require secure contexts and user gestures.
  • DeviceOK asks for sensitive permissions only when a user starts the relevant test.
