The gyro-stabilized marine PTZ system integrates HD visible light camera, cooled/uncooled thermal imaging, laser ranging/illumination, high-precision gyro image stabilization, automatic tracking module, and precision electronic control system. It can be installed on large ships, unmanned boats, law enforcement ships, marine mobile carriers such as fishery administration ships, and maritime surveillance ships. The system can be used to achieve stable acquisition of long-distance sea and aerial target images under complex sea conditions, and to realize functions such as surveillance, obstacle avoidance, search, alert, follow-up, and evidence collection.
