Using a DSLR I can use a wide rage lenses, shoot as much faster shutter speeds, separate the sensor from the camera, and use multiple strobes for creative lighting. A passive IR sensor would capture movement outside of the area of focus, an active IR beam, as described in this instructable would trigger the camera only when the beam is broken.

Better quality images.

Fixed. Thanks for noticing.

I only work with Canon cameras, but as long as you have a method to trigger your Nikon with a cable, you should be able to use this Instructable.

I've never used a wireless remote for my camera trap photography. I'm not sure how to mod your remote, but I'm sure its possible.
