“…Deployed surveillance instruments include border walls and fences monitored with infrared camera systems and motion sensors, patrol vessels and vehicles, hightech sensors, thermo-vision vans, geographical information systems, automatic identification systems, radar systems, helicopters, surveillance coordination centres, and, recently, drones (at testing stage), satellites, and the Eurosur (e.g., Topak 2014a; Jones and Johnson 2016; Topak and Vives 2018). The Eurosur is designed to work as the "system of systems" through gathering surveillance data from diverse units and technologies into a single centre and producing situational pictures of the borders (Jeandesboz 2011;Duez and Bellanova 2016). It is used in "monitoring, detection, identification, tracking, prevention, and interception of unauthorised border crossings" (European Council 2013).…”
