The Raspberry Pi camera is available in two versions. As normal camera with infrared filter and as NoIR camera without infrared filter. This means that pictures you take by daylight will look decidedly curious on the NoIR camera, but it gives you the ability to see in the dark with infrared lighting. Furher infos here and here.
