60 Hz 1/120 exposure, (to eliminate rolling shutter) NR=1
Garbage

To be fair - you should show here how image / video with the same exposure / shutter looks from 5442...
A big problem with WizColor / AI-ISP cameras is that because they can "paint" a beautiful bright color static image at 1/100s to 1/250s at night in low light, we think the same applies to moving objects.
This is not true. In such conditions, the sensor sees more noise than the image. Simply turn off noise reduction completely (NR on/off switch) to see what the camera sensor actually sees.
The AI makes up for a lot here... Much more than in the 5442. In the 5442, the image in such conditions (on full auto mode) would be dark, noisy, have ghosting, and be blurry.
In full manual mode, something could be improved on the 5442 - but at 1/120s in color mode it will be far from ideal.
I tried many times to catch European very visible car plates / car details in color mode using 5442-Z4E / 7442-Z4 on low speed streets. Very low success ratio. In IR mode with my full WDR trick works very well.
The problem is that in those new cameras, some of the settings perform poorly - we have little control over some of the AI NR. Plus there is wrong exposure time / gain auto mechanism..
Let's hope Dahua refines this issue. It looks like they received magic box (AI-ISP) from SOC vendor and they don't have big control over it.
ps. those 5x59-PRO cams starts to show in normal Dahua worldwide distribution.. this should speed up fixing them by Dahua...
Bigger situation picture about new Dahua cameras:
Problem is that Chinese CCTV sensors lacks any development in last 4 years.. There are newer western Sony Starvis 2 CCTV sensors, but nor Dahua nor HIK are using them (due political situation & price difference)..
CCTV sensors are very low cost solutions - so no one invest heavily here.. the same story is in SOC space - HIK / Dahua are using cheap SOC's which are mobile knock-off from 3-5 years ago...
For me the only proper solution is switching to high resolution Quad Bayer image sensors, used heavily in mobiles & sport cameras / drones.. All sensor development is going there, every 1-2 years there is a big progress there...
They allow to do 8K video at day & 4K at night (with higher sensitivity).. which have big use in CCTV space (double vertical/horizontal resolution for a day doubles DORI)..
And should be NEW BIG revolution in CCTV space..
