Camera visible in Windows but not active in the app

  • Wait a few seconds — USB detection can take a moment after the camera is powered on.
  • Power-cycle the camera (turn off and on), then check the app again.
  • Verify that the correct backend is selected in Settings → Camera (Canon / Nikon / Sony).
  • Restart the app if the camera was swapped repeatedly during the same session.
  • Close Canon EOS Utility, Nikon Camera Control Pro, or any other software that takes exclusive access to the camera.

Live view is slow or unavailable

  • Confirm the camera supports live view over USB — check your camera model's specification.
  • Close other camera-control software that may be sharing the USB stream.
  • Use a direct USB port on the PC rather than a USB hub or dock.
  • Ensure the camera battery or AC adapter is stable — power fluctuation interrupts live view.
  • Try reducing live view resolution in Settings → Camera → Live View Quality.

Live view freezes mid-session

  • Check that the camera has not entered sleep mode — disable auto power-off in the camera menu for events.
  • If using a USB hub, move to a direct port on the PC motherboard.
  • Check that the USB cable is not loose — cables under repeated stress at events can develop intermittent connections.

Camera disappears after a long idle period

Some cameras automatically turn off live view after a timeout. Set the camera's live view timeout to the maximum value in the camera menu, or disable it entirely.

App does not see the camera at all after reinstall

  • Reinstall the app as administrator.
  • Confirm the camera is set to PTP or PC Remote mode (not Mass Storage).
  • Check Device Manager for USB errors or unrecognised devices.
If you have tried all steps above and the camera still does not work, contact support with your camera model, Windows version, and a description of what you see in Settings → Camera. Include any error messages shown.
