8. Troubleshooting
8.1 Device Not Recording
- Check SSD: Ensure the SSD is properly inserted and formatted.

- Camera to Cloud Client: If the Camera to Cloud (C2C) Client is enabled, the device may not record to the SSD. Disable C2C if local recording is desired.
8.2 Overheating During Long Sessions
The Ninja Ultra may generate heat during prolonged use, especially when recording in high resolutions or demanding codecs. Ensure adequate ventilation around the device. If overheating persists, consider reducing recording settings or taking breaks.
8.3 Connectivity Issues
- HDMI/SDI Signal: Ensure cables are securely connected and the camera is outputting a valid signal.
