>>102361 Ok i'll bite, Yes it stands for Infrared.
>>102335, This pic involves a filter that is placed in front of the camera lens (costs about 25-75$), which only lets Infrared light pass. Unfortunately camera's also block IR infront of the sensor, so it needs long shutter speeds, and high ISO's even during the daytime to expose properly.
My version costs much more, BUT it removes the IR blocking filter infront of the sensor (in my case a D70) And replaces it with the same material the R72 uses (720nm wavelength cutoff) This way the cam will autofocus, and allow a lot more light to hit the sensor (roughly equal to what visible light is) so the camera even meters properly (Unlike slapping the filter on) www.lifepixel.com did mine. Total cost would be around $600-700 for a similar setup.
BTW heres a comparison non IR pic for reference
