Use Internet Explorer which is still available in Win10. Just type "explorer" in the search bar. Some Dahua cameras are sensitive to what browser is used and IE is what the web UI was designed for.
All the settings are available in the settings tab. General conditions, brightness, contrast, etc. The exposure tab sets shutter control, speed speed and exposure compensation. The rest are basically self explanatory. The Day/Night tab will let you set the basic mode, such as auto, color or B&W. Many use the Sunrise/Sunset utility to force a manual change of day and night settings based on the changing sunset and sunrise times rather than the time only limitation of the camera firmware.
Most of us use a manual shutter speed rather than "auto". Day settings of 0.001 to 16.66 ms work fairly well. Night settings are similar. Exposure compensation is a balancing act to keep noise low. Slowing the shutter below 16..66ms, about 1/60th of a second, will result in blur especially at night..
I normally don't' use WDR, wide dynamic range, or any other enhancements like that. They generally introduce noise and/or blur especially at night. If you do use them try to keep the gain as low as possible to keep blur to a minimum.
With the 5442 most run a CBR, constant bit rate, set at 8192. Frame and iframe rates should match and 15/15 is fine for video surveillance. Encoding is another Catch22. I use H264 exclusively but others use H265. Don't use H265+ because it is more or less a proprietary encoding that may not be compatible with your VMS software.
Bottom line is to fool with the settings for both day and night to balance them all for the best possible video. Avoiding blur at night is the hardest part.
If you get stuck, just ask but post the question with screen shots of the settings.
