With drones and thermal cameras, Greek officials monitor refugees

Athens, Greece – "Let's go see something that looks really nice," says Anastasios Salis, head of information and communications technology at the Greek Migration and Asylum Ministry in Athens, before entering an airtight room sealed behind two interlocking doors, accessible only with an ID card and fingerprint scan. Beyond these doors is the ministry's newly-installed centralised surveillance room. The front wall is covered by a vast screen. More than a dozen rectangles and squares display footage from three refugee camps already connected to the system. Another screen shows the playground and another the inside of one of the containers where people socialise.
