A lot of the models that used to mention STARVIS in the specs now say CMOS instead. Not sure why Dahua changed that. There are different sized STARVIS sensors that can be paired with different lens (2MP, 6MP, 8MP). I’ve only seen the combination of the 1/2.8” (or 1/1.8”) sensor combined with a 2MP lens get the Starlight tag. If you search the Dahua forum here for threads that have “Review” in the title, you should easily find a lot of info on the popular Starlight models.
