alt Hacker Newsi think its the wrong end of the stick, sony created a camera that is sensative to IR. textile manufacturers created IR transparent fabric.
im not the biggest fan of sony, but blame [if you are into that] should be pointed in a different direction.
to wit: black and decker accidentally invented a hammer that bends nails, and smashes fingertips.
The stick has a third end - people added an IR transmitting filter so they could record in near-IR during daylight.
