> Very high quality visual/signals surveillance seems like a much more obvious market fit. Oh, yeah, there are already companies the provide complete surveillance of cities or large areas of cities so that even if a crime scene is discovered hours or days later, they can just go back to that time and track vehicle movement to and from the crime scene to wherever it ends up as long as it's in the same (large) area. Reducing the cost of the equipment that does the recording of the area will only make it more accessible to more police departments, for better or worse.
