The Smart Surveillance Buoy (SSB) is an advanced autonomous system designed for real-time surveillance and monitoring of water bodies. Equipped with sensors, cameras, and IoT technology, it is capable of tracking underwater activity, detecting anomalies, and sending data for aNolysis. Its primary applications include coastal surveillance, environmental monitoring, and safety operations in maritime environments. The system offers benefits like remote monitoring, reduced human intervention, and real-time data access for better decision-making in sectors such as defense, aquaculture, and environmental conservation. By integrating AI and machine learning, the buoy can optimize its operations and identify patterns in water activity or potential threats.
