The camera used has to have a CCd that is sensitive to
near IR and IR, plus no hot mirror filter. Older CCDs used to be
susceptible to noise from IR and used a hot mirror filter to block
IR from reaching the sensor. Newer CCds are less prone to that and
some allow IR to pass through to the CCD. hence, you can do IR
imaging, it is just reflected IR in the near visible wavelengths.
