We recently produced Settlement Documentaries where we used 2 different cameras to inconspicuously shoot high definition video (wide angle if needed) in a hospital room and from the dashboard of a car traveling 75mph on Highway 27 in Clermont at 3:00am. These cameras enabled us to capture video and audio in environments where it is typically difficult to acquire access. The GoPro camera we used also shoots under water.
