Camera Appears as UnknownBoot

When to use this article​

  • The camera is detected as UnknownBoot.
  • The device cannot stream.
  • VizionViewer does not recognize the camera correctly.

What this means​

The device is likely in bootloader mode. Firmware may not have been successfully loaded, or the firmware may be corrupted.

Recover the camera firmware​

  1. Open VizionViewer.
  2. Run the Recondition Tool to reflash the firmware.
  3. Do not disconnect the camera or interrupt the update process.

If the firmware update fails:

  1. Export the log file from VizionViewer.
  2. Try a different USB cable. A short, high-quality cable is recommended.
  3. Retry on another PC, preferably a desktop with a direct USB connection.
  4. Avoid USB hubs during the recovery process.
  5. Send the log file to TechNexion support for analysis if the issue persists.

Check the result​

After reconditioning, reconnect the camera and confirm it appears with the expected camera model name instead of UnknownBoot.

If recovery fails​

  • This condition is typically recoverable.
  • Unstable USB power or signal quality can cause firmware update failure.
  • If the issue persists after multiple attempts, further inspection may be required.
