Thanks for your advices, fenderman~
For parameter settings, there are several automatic choice to change the parameter based on image, like day-mode and night-mode switch, but yeah, like the WDR, there is only turn on and off options now. We will make improvement on this part.
For night vision, for the camera which supposes 3D noise reduction, the image quality is good as far as I know, we have also some star-light level camera which has a good perfermance in the evening.
Best regards,
