I don’t know if it’s the video you’ve mentioned previously, but I watched a comparison recently that gave me the impression that Cam OG has superior night vision to Cam v4 (typical “night vision” using IR, not the “color night vision” with the starlight sensor). I get great results with Cam OG on the “dark” setting in a garage at night.
I think it depends on which camera model(s) you might consider and what your intended use case(s) is/are. I have experience only with the C120, and at its price I think it beats Cam v4 in a number of feature areas (most notably “free” AI-enabled detections). I left my initial impressions about that in another topic.
