It was explained pretty much the same way then, as it was above. By me actually.
To capture motion, more light is needed to correctly expose the frame. Stationary objects expose great in low light conditions because they don’t move. There are some folks in here that have great photos of birds in flight, because for that fast motion you need alot of light, and in every photo of birds in flight I’ve seen with a Wyze Cam has been in direct sunlight or in a really luminous area.
