I don't know enough about this yet Vv, what is the mm rating and FOV of the ones you have? I am trying to figure out if the 1.8mm or 2.8mm would be better for this application. From what I am seeing trying to learn about this, most seem to like a 2.1 to 2.5 mm lens on their run cams so I am trying to find a suitable mm size to eventually mod the sq11 I have on order.
