DK2 and IR camera systems

I'm considering buying an Optitrack camera system and I was wondering how it would work with the DK2. Since the markers on the DK2 are infrared, could I use the Optitrack cameras to track the DK2 instead of the supplied camera? If I used the Optitrack cameras for passive IR markers and the DK2 camera for the DK2 would I run into interference problems? I know that Oculus has an Optitrack system so I'm hoping that someone can answer my questions. Thanks in advance.
