IR and UV are two different color spectrum. It is beveled that deer can see a little bit of UV, a study in 1992 by the The University of Georgia found that deer lack the UV filter that humans have. They do also have a cone to pick up blues, so it would appear that deer can pick up some UV.
But IR is different. Red and blue are on two diffrent sides of the visible color spectrum. IR is on the red side, UV is on the blue side. Deer lack the ability to see red, so IR is out of the question. So if your camera is using true IR, then I wouldn't worry about it. But like Isnipe said, if your concerned check it out under a black light.
