Lot of noise/blurry image with DS-2CD2347G-LU 4MP. Need advise.

See video for what I mean.
Can someone explain how this is possible or is this just because there is too little light in the area? You see a lot of noise / blur on the street and around the white bus. License plate itself is very difficult to see. What can I do about it? I would like your help and advice on what this could possibly be. Shutterspeed is 1/500. WDR is OFF and 25FPS. Camera is 6mm
I had the same problem with H265 compression selected, after I switched to H265+ the blur was gone.
Both (DS-2CD2347G2-LU) of my have the same problem with H265.
