A guest at the club had a talk about this very subject so will pass one what i can remember of it. Apperantly, the sensors are very senative to IR but the camera manufractors put an IR cut filter in front of the sensor as part of the sensor assembly. All that is required is to remove that IR cut filter and you have an IR camera. No need to add IR filters to the lens once this is done. Most camera repair places can do this for you.
I haven't researched this, only going by what this guy said. He has taken many IR photos with his modded camera.
