Tech company has installed the advertising screens in hundreds of apartment blocks across 20 British cities
Digital billboards that can film viewers’ responses to adverts have been installed in hundreds of apartment blocks, in a move that civil liberty campaigners called “creepy as hell”.
The supplier, 30Seconds Group, says the cameras allow them to track “occupant engagement” from residents who are a “captive audience” as they wait for lifts to their apartments.
