Troubleshooting
If you encounter issues with your camera, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No image or black screen | Loose cable connection, incorrect input selection on display, insufficient power. | Check all cable connections (USB-C, HDMI). Ensure the display is set to the correct input source. Verify the USB-C power source provides 5V 2A. |
| Image is blurry or out of focus | Lens not properly focused. | Manually adjust the focus ring on the lens until the image is sharp. Refocus after adjusting zoom. |
| Camera not recognized by PC | USB port issue, operating system incompatibility, software conflict. | Try a different USB port. Ensure your operating system (Windows, Linux, macOS, Android) is supported. Close other applications that might be using the camera. Restart your computer. |
| HDMI output is 1080P instead of 4K | HDMI output specification. | This is expected behavior. The HDMI output is 1080P, while the USB 2.0 output supports 2160P (4K). |
| Image quality appears poor | Low light conditions, incorrect software settings, dirty lens. | Ensure adequate lighting. Check camera settings in your software for resolution and compression. Clean the lens. |
