For Night Vision your looking at something like a 960H compatible camera either sony Effio E or even better the P Range, The night vision on these is Great for the price and no need to fear of that over contrast/Brightness look when it picks up someone wearing shiny/reflective material.
Obviously to get the best out of it you need to couple it with a 960H Recorder, As with anything depends on what you want to spend if you want ease of use for wiring then Kguard are doing a 960H IP camera system and you just use Cat5e 4 cameras and Recorder for around £680
