      Surveillance allows with different levels of answers the protection of infrastructures and sensitive sites (submarine bases, ports, wind farms, submarine cables, shock point, border control). It prevent against the intrusion of unmanned underwater vehicles or enemy divers, who can threaten to these installations.

      The water column can be used to illegally transport goods or people. Surveillance can help fight against drug trafficking, arms smuggling, and other illegal activities.

      Surveillance can be undertaken with the installation of instrumented, connected stations. Information management is achieved via data recording or real-time transmission to detect and report any change of activity.
