What is a Dual-sensor Panoramic Camera?
Dual-sensor panoramic cameras utilize two sensors for image capture, providing an exceptional field of view and remarkable image quality. This dual-sensor configuration enhances versatility and elevates image quality, outperforming their single-sensor counterparts.
What is it designed for?
Leveraging their ultra-wide field of view, dual-sensor panoramic cameras are ideally suited for monitoring expansive and open spaces. These include parks, recreational areas, parking lots, shopping centers, public squares, streets, stadiums, and transportation hubs, etc.
What is the Splicing Distance?
Splicing Distance refers to the specific distance at which a dual-sensor panoramic camera merges two video feeds into a cohesive image. It is crucial to establish an optimal Splicing Distance according to your specific application scenario.
Note
A Splicing Distance that is excessively long may result in the central portion of objects appearing truncated.
Conversely, a Splicing Distance that is too short may lead to a double image effect on the objects.
Therefore, careful calibration of the Splicing Distance is essential for optimal camera performance.

Figure 3 Too Long – Truncated
How to Configure Splicing Distance?
The Splicing Distance can be configured through the camera’s webpage, the webpage or the HDMI/VGA output of the connected Milesight NVR.
For optimal monitoring performance with dual-sensor cameras, it is recommended to set the Splicing Distance at a point where objects most frequently appear. This careful calibration can significantly enhance the surveillance experience. Suppose that the monitored objects (vehicles, human, etc.) appear mostly frequently at a 15-meter distance away from the camera, setting the Optimal Splicing Distance to 15 meters would presumably offer the best monitoring experience.
Note
If the image is inverted after installation, you perform a 180-degree rotation on the Live View page for a better experience.

Steps:
1. Access the webpage of the camera.
2. On the Live View page, find Optimal Splicing Distance icon on the toolbar at the bottom of the page.

3. Click on the icon to open a pop-up pane.
4. Adjust the Splicing Distance (within the range of 0.5 to 30 meters) by dragging the slider or entering the desired distance into the text box.
5. To reset the Splicing Distance to its default value (10 meters), click on the reset icon.
Alternatively, you can also set the Splicing Distance in the configurations of the camera. Navigate to Configurations – Media – Image - General to find configuration for Optimal Splicing Distance. The adjustment method remains the same as described above.

If you connected your dual-sensor panoramic camera to a Milesight NVR, you can also configure the Splicing Distance on the webpage of it.
Steps:
1. Access the webpage of the NVR.
2. On Live View page, play the stream from the dual-sensor camera.
3. Click on the Optimal Splicing Distance icon on the toolbar at the bottom to open a pop-up pane.

4. Adjust the Splicing Distance by dragging the slider or entering the desired distance into the text box.
5. To reset the Splicing Distance to its default value (10 meters), click on the reset icon.
Via the HDMI output of the connected Milesight NVR
You can also configure the Splicing Distance on the local GUI of the NVR it is connected to.
Steps:
1. Navigate to the Live View interface and play the stream from the dual-sensor camera.
2. Single-click on the image to reveal a toolbar at the top of the screen.

4. Adjust the Splicing Distance by simply dragging the slider or using the up/down arrow next to the text box.
5. To reset the Splicing Distance to its default, click on the Default button.
6. Click on the Close button to finalize the configuration.
