From 2008 to 2014, !Mediengruppe Bitnik conducted walks through the sceneries of invisible cities: equipped with self-built CCTV video signal receivers and video recording devices they organise dérives in search of hidden — and usually invisible — surveillance camera signals in public space. Surveillance becomes sousveillance: the self-built tools provide access to “surveillance from above” by capturing and displaying CCTV signals, thus making them visible and recordable.
