I just double checked the settings and the night vision is forced to ON. If it is set to OFF, then you will get color recordings. If it is set to AUTO, it might switch between black/white and color, depending on how much light is available.
Over Christmas, I had 2 cameras pointed in the same direction. One had night vision ON and the other OFF, in hopes of getting a color shot of a meteor. Still have to go through that footage.
