Cameras would be like cockpits in terms they give players another viewport, but at the same time, you'd have access to systems linked to your core (or last chosen cockpit), so you'd get best of both worlds - good overhead of area and ability to have well protected (buried under tons of heavy hull) core while having access to weapons and other systems connected to it. Since cockpits are changed using left/right arrows, cameras would be changed using up/down ones.
