British designer James Bridle recently created what he dubs the “Surveillance Spaulder” – a medieval-themed wearable “armor” device that detects closed circuit television cameras AKA surveillance cameras. He did so by combining a 730nm bandpass filter – to detect the infrared light commonly used in CCTV cameras – and a pair of transcutaneous electrical nerve stimulation (TENS) pads – to send a current when activated. The result is a shoulder pad fit for James Bond himself. Or Banksy. Or anyone needing to stay out of the sight of nearby security cameras.
