Many digital cameras have IR blockers to prevent these wavelengths from interfering with autofocus etc. My experience is that there is a wide variation beween cameras but they appear, in my limited experience, to be moving to less IR sensitivity. However there are a few that advertise that they have night vision capabilities, for example some Sony models, and they achieve this by removing part of the IR block for very low light. So, you either need a higher power IR source, or a different camera if you need to capture with fast shutter speeds.

As far as setting the camera to B&W, I understand that this is done as part of the post capture processing so would probably not help.

Good luck
