6. Troubleshooting
If you encounter issues with your ELP 4K HDMI USB Camera, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No image/video output | Loose cable connection, incorrect input selection on monitor, software not detecting camera. | Check USB and HDMI cable connections. Ensure the monitor input is set correctly. Verify camera detection in your software/OS settings. Try a different USB port or cable. |
| Poor image quality/Blurry image | Incorrect focus, insufficient lighting, software settings, lens smudges. | Adjust the manual focus ring on the lens. Ensure adequate lighting. Check resolution and frame rate settings in your software. Clean the lens. |
| Image distortion at wide angle | Characteristic of wide-angle lenses. | This is a common optical effect for wide-angle lenses. Adjust zoom to a narrower field of view if distortion is problematic. |
| No audio recording | The camera does not have a built-in microphone. | This camera is designed for video capture only. Use an external microphone for audio recording. |
| Low frame rate at 4K resolution | System limitations, software settings, USB bandwidth. | Ensure your computer meets the minimum requirements for 4K 60fps video processing. Check software settings for frame rate. Use a high-quality USB 3.0 port and cable. |
