Yes as
@EMPIRETECANDY mentioned, in my testing of full color 4Ks vs their 4MP full color siblings, the 4Ks win out for sure thanks to their low light processing capabilities afforded by the larger 1/1.2” they possess. The 4MP cams have come on a long way with the Dahua 5442 being a star performer for sure and the full color 4MP handling night (in color) better than even the 5442 could. However, still relying on 1/1.8” does limit light gathering AND introduces more noise than the larger sensor.
Just remember, sensor is important, I never advocate for just increasing pixel density across a smaller sensor which has happened across many manufacturers on earlier 4K builds but we’re now starting to see higher performing cams utilizing improved SOCs, optimal 1/1.2” sensors and low dispersion optics.
Dont get me wrong, I’m not saying deploy these everywhere and certainly don’t expect miracles if FOVs are completely dark
You still need light to bring out the best, are better off balancing a location with blended cams (4K full color + dual lens or decent 4MP with IR across the location), ensuring you install for the target type and special applications you need to cater for (LPR, face recog, PTZ etc) along with always dialing in for the FOV correctly. The benefit now though is you have more latitude and options due to these new cams like the Color4K-X.
