Using IR LEDs To Hide In Plain Sight

Getting by without falling under the gaze of surveillance cameras doesn’t seem possible nowadays – from malls to street corners, it’s getting more common for organizations to use surveillance cameras to keep patrons in check. Freedom Shield built by engineer Nick Bild is an attempt at breaking away from the status quo and giving people a choice on whether they want to be seen or not. The spectrum of radiation visible to humans maxes out around 740nm, allowing the IR waves to remain undetected by normal observers.
