The STYRIS® coastal surveillance system was developed to address the growing challenges of ensuring safer oceans, monitoring dense maritime traffic, preserving wildlife, securing borders, and preventing illegal activities such as drug trafficking and smuggling. By integrating various sensors—including radar, weather, AIS, and VHF—STYRIS® provides real-time data collection and a comprehensive situational view of maritime areas. This allows end-users, such as navies, coastguards, and maritime authorities, to monitor vessel traffic efficiently, ensuring the safety of navigation and enhancing critical response capabilities in emergencies. The system's responsive software interface offers instant access to information on vessels, including ID, speed, and heading, while identifying dark vessels that have turned off their AIS signal. Customizable operational alarms enhance the detection of abnormal behaviour, making STYRIS® an essential tool for day-to-day maritime operations and security.
