Surveillance Drone: Fairly ubiquitous, between the governance (for law enforcement, and externality monitoring, and infrastructure maintenance, and city management AIs, etc.; all – due to the transparency rules – open to general public use), odocorps, private security, edgehunters, newsies, vloggers, lifeloggers, and narcissists.
Faceless Eye: Citizen Oversight, the unified office of collecting publicly available data so that what government the Empire has can make sensible decisions (and which, incidentally, pays for itself by selling the statistical information, and collations, and indeed access to the raw feeds – for assorted uses, sousveillance included – it produces on the open market) uses as its logo, of course, the all-seeing eye.
