It offers options to adjust the focus mode and the minimum focus distance.
The device focuses automatically as the scene changes. If you cannot get a well-focused image under auto mode, reduce light sources in the image and avoid flashing lights.
The device focuses once after the PTZ and lens zooming. If the image is clear, the focus does not change when the scene changes.
You can adjust the focus manually on the live view page.
When the distance between the scene and lens is shorter than the Min. Focus Distance, the lens does not focus.
