AI-based motion detection can be used in different contexts to surveil and monitor people whose freedom of movement is restricted during screening, asylum and deportation procedures. One example of this is the "Closed Controlled Access Centres" (CCACs) in Samos, a model could be expanded with the implementation of the EU Migration Pact. Greece opened these new types of camp for asylum-seekers on the island of Samos in September 2021 with the support of EU funds. CCACs rely on the use of numerous surveillance technologies, including cameras, drones and biometric data processing.
The Closed Control Access Center (CCAC) in Samos, Greece, serves as a reception and identification center and facilitates the screening of first arrivals. It also has a separate section for pre-removal detention. The CCAC is equipped with at least four IT systems: Centaur, Hyperion, Rea 15 and Alkioni ΙΙ. The Centaur system transmits CCTV and drone footage to a control room at the Ministry of Migration and Asylum, and deploys motion analysis algorithms to analyze footage. Centaur is deployed for the purpose of controlling the movement and analyze the behaviors of those detained inside the facility. This reflects a general suspicion of those staying in the facility and contributes to a situation of de facto detention in a facility intended for the reception of asylum seekers. The Greek Ministry of Migration has been fined for violating privacy rights in the context of deploying the Centaur and Hyperion system.
