For movement you want to be running a fast shutter anyway. A classic mistake is to obtain a "good"picture by boosting up gain and slowing shutter right down, only to get semi transparent nreognisable trailing ghosts when someone moves. The quality of your pic at night is always dictated by the shutter speed. You want gain at a max of 50 on many cameras and a shutter of 8ms or less, preferably 4ms. If your camera can't manage that and still see, then you need either a different camera or supplemental lighting. One of the new cameras that switches from IR to colour with illumination is probably the ultimate compromise here as you ge the best of both worlds. However, I'd wait for reviews. The other option is some low inensity white lighting with floods that engage if movement is detected, but that kind of violates your no light pollution requirement. You need to understand though, that non IR cameras do need at least some light to see, and the brighter the lighting the better the picture. Hence why with my 4kt camera, I run a 5w led bulb all night on a dsuk to dawn sensor (about 350-400 lumens), then although I can get a decent picture from that, I have a sensor activated 30w led floodlight that activates on movement to boost the picture quality if anyone is present. I get a picture either way then, but the boosted picture is far superior.
