When Hikvision upgraded their old 3MP DWDR cameras to the new "120dB" WDR 4MP electronics, the WDR quality increased noticeably. However, it seems that all their new cameras 5MP and above (including the 6MP, 4K models) are all DWDR again. Is this a step backward due to some limitation with the 5+MP electronics resulting in actually worse WDR or is it just a name change with no noticeable impact on the WDR quality?
Anybody has experience with those?
