Looking at the pics, it appears to be a simple IR-based nightvision system, and not the more expensive light amplification-based ones. Still cool though, looks neato.FYI: You can build one of those very easily and for pretty cheap. Get a cheapo webcam or old camcorder...preferably one that's only black and white or has a black and white mode. Then get some of the biggest, brightest IR LED's you can find, build a power supply, and make an array out of them. Best way to do it is similar to the pic, a ring of them around the camera lens with a reflector of some sort. Turn on the LED's and put the camera in the dark, and there ya' go. It's basically a huge IR flashlight that only the camera can see. Nice quick project for a Science Fair in HS (do they still do those?) or a college electronics course.
