Look i'm not even the slightest bit interested, but since this is a geek site, i'd thought people could mythbust this for everyone.

http://www.sella.co.nz/general/electronics-photography/video-cameras/accessories/other/56hynb/ ;-) looks legit, going by a quick look around, screws on top of the existing lense then you enable night vision. Although most people have stated has to be dark clothes, and it looks B&W due to having to use night vision for it to work.

"Used with a video camera equipped with "0 LUX" nightshot/cat's eye/nightview/nightvision you will be able to take "x-ray" videos i.e YES, you can really see through thin clothing and swimwear (especially artificial fabrics such as polyester, nylon). This works because unlike visible light, infrared light does not reflect off clothing. Instead, it passes through thin fabrics and is reflected by the denser skin. This is because infrared light has a longer wavelength than visible light. Video cameras can detect light up to around 1400nm (visible light ends at 750nm). The infrared filter only allows the infrared light through, hence the "Xray" effect is possible. Without it, the camera will be saturated with both visible and infrared light, resulting in a white picture.:

Sony had some issues with digital and still digital cameras probably 10 or so years ago now. They had a nightshot mode and you used an IR filter you could do the same thing. I believe they changed the software in later versions so nightshot could actually only be used only in low light conditions.
