Fun fact: if you have dark eyes, taking photographs of yourself in near-infrared will make your iris' appear light, which is good if you're going for that trendy vampire look. I'm not really impressed by the technology behind this - IR pass plastics have been around for ages (the black plastic window on the front of your TV remote is an example).

But as for these guys...

"We have developed a technology to create covert concealment devices out of a material that black & white cameras can see through, BUT THE HUMAN EYE CANNOT!"

I may be wrong, but it seems to me that what they "developed" was a relationship with an injection molding company, whom they asked to use a slightly different, but still common plastic.
