Building an (IR) infrared-veil

2610354621Yallla writes “For the 22C3 some people from Vienna conducted some CCTV wiretapping experiments; in a sidenote they said that infrared light is disturbing CCTV cameras. I’m now conducting experiments about how you could exploit that feature of CCD-sensors to create some kind of infrared-veil – like a basball cap full of IR transmitting LEDs, spoilng the CCTV footage experience of your airport security staff. Goals of my experiments are if it’s really working, what type of LEDs are suitable and what happens to me in real life when i just say “Shields up!!” Link to the MAKE forum postproject page.
