* Click on the "Auto White Balance" button to adjust the camera's white balance automatically.

Step 4: Field of View (FOV) Calibration* For face recognition applications, use the "FOV Assistant" tool.
* Mark the area where subjects will be detected and ensure it is within the camera's field of view.
* Adjust the camera's zoom and tilt to fit the desired area.

Step 5: Focus Calibration* Go to the "Focus" tab in the software.
* Select the "Auto Focus" mode for optimal focus at all distances.
* If necessary, manually adjust the focus by clicking the "+" or "-" buttons until the image is sharp.

Step 6: Lens Distortion Correction (LDC)* Enable LDC in the "Camera Setup" tab.
* Select the appropriate "Lens Model" from the drop-down menu.
* Adjust the "LDC Gain" and "LDC Threshold" settings to minimize lens distortion.

Step 7: Backlight Compensation (BLC)* Enable BLC in the "Camera Setup" tab.
* Adjust the "BLC Level" and "BLC Mode" settings to compensate for high contrast scenes, such as those with bright backgrounds.

Step 8: Advanced Calibration* For specific applications such as perimeter protection or license plate recognition, refer to the camera's user manual for specific calibration procedures.
* Use the advanced settings to fine-tune the camera's sensitivity, motion detection parameters, and other features.

Step 9: Save Settings* Once the calibration is complete, save the settings by clicking on the "Save" button.
* The camera will store the new calibration parameters and apply them automatically.

ConclusionCalibrating Dahua surveillance cameras is a crucial process to ensure their optimal performance. By following the steps outlined in this tutorial, you can effectively adjust various camera parameters, including FOV, focus, LDC, BLC, and advanced settings. This ensures accurate image capture, enhanced image quality, and reliable detection and recognition capabilities. Remember to refer to the camera's user manual for specific details and additional calibration options.
