7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No image/signal on monitor (SDI output) | Incorrect video format/frame rate setting in OSD menu; faulty cable; power issue. | 1. Ensure power is connected. 2. Check SDI cable connection. 3. If no SDI signal, connect via CVBS output to access OSD menu. Navigate to System > Frame Rate and adjust to a compatible setting (e.g., 1080_30I or 1080_30P). |
| OSD menu not visible | Monitor not compatible with current SDI output settings; SDI cable issue. | Connect the camera's CVBS output to a standard composite video monitor to access and configure the OSD menu. |
| Image is blurry/out of focus | Lens focus not adjusted correctly. | Manually adjust the focus ring on the lens until the image is sharp. |
| Poor color reproduction/grainy image | Insufficient lighting; incorrect white balance or exposure settings. | 1. Ensure adequate lighting in the surveillance area. 2. Adjust White Balance and Exposure settings via the OSD menu. 3. Note that some chromatic aberration may be present depending on lighting conditions and lens characteristics. |
| Camera not powering on | No power; faulty power adapter; loose connection. | 1. Verify the power adapter is correctly connected to a working power outlet and the camera. 2. Ensure the power adapter is DC12V 1A. 3. Test with a different compatible power adapter if available. |
