CCTV - You are never alone
Within the scope of the OpenSquare events hosted by Carré Rotondes, the Chaos Computer Club Lëtzebuerg (C3L) invites you to an information evening about daily mass-surveillance in Luxembourg.
Closed-circuit television (CCTV) systems have been massively deployed in public and private areas over the past two decades throughout the country. The more technological knowledge and implementation methods evolve, the more these digital all-seeing eyes are able to spy on us, on every hour, every day.
Since years, C3L is calling attention to the endangerments to citizen and human rights, radiating by these systems.
In order to depict the violations of privacy, exercised by these systems; we aim at nothing less, than, informing citizens about their rights, possible dangers, reasonable deployment areas, prevention measures as protections from these always on the watch lenses.
