Border and coastal defense is crucial to national security and overall development. Traditionally, frontline coastal defense tasks are arduous, with significant pressure from counter-infiltration and anti-smuggling efforts. The integrated air-ground construction of smart border and coastal defense presents a significant opportunity to enhance defense effectiveness. Drones equipped with high-performance optoelectronic pods can conduct large-scale maritime patrols, achieving dynamic monitoring across the entire area. Intelligent optoelectronic turntables, serving as border and coastal defense monitoring equipment, possess a dual-spectrum system with visible light and infrared thermal imaging, enabling 24/7 monitoring without blind spots, accurately capturing target details, and locating suspicious targets in nighttime environments. Integrating AI algorithms and high-precision control technology, they can lock onto and track moving targets, filter interference, and achieve intelligent "identification-tracking-early warning." The two work in tandem, simultaneously transmitting high-definition images, providing precise support for command and decision-making, becoming powerful tools for safeguarding maritime security and combating illegal activities, and contributing to the construction of a comprehensive, three-dimensional, intelligent border and coastal defense system.
