The axis cameras do have IR filters, but at least for the 206 it was on the lens, not the sensor. I suspect that the M1011 is the same, but can't be certain.

If you choose to use IR, you may want to consider setting the camera to monochrome and if it returns an RGB image, simply take one of the planes such as red. This should reduce time needed to process.

Last year I took some movies of the field using a Kinect and there seemed to be lots of IR coming from the lights above and to each side of the field. This light would bounce off tape stripes, plastic, and of course other robots. I'm not saying whether IR is or isn't a good choice.

One of the issues is that you can't see IR. Just because you don't see it doesn't mean it isn't there.
