The Maritime Shipborne Video Surveillance System Solution addresses the challenges of navigation safety and shipping regulation in China's rapidly developing inland, coastal, and ocean shipping sectors. It provides ship operators and government regulatory authorities with a comprehensive video surveillance system integrating video acquisition, storage, and playback/retrieval. This system monitors critical internal areas and the external environment of medium to large vessels during operation, and can be used for vessel navigation safety analysis, ensuring maritime safety, and meeting the needs of shipping development in the new era.

Background and Challenges

With the rapid development of China's social economy, shipping, as a convenient and low-cost mode of transport, is continuously increasing its share in the transportation industry structure. The vessel traffic volume in inland, coastal, and ocean shipping is growing steadily. Concurrently, with the public's pursuit of quality of life, water (maritime) tourism involving vessels is also flourishing. The increase in vessel traffic leads to greater difficulty in preventing and controlling water navigation safety issues and increased regulatory pressure. This poses new challenges for ship operators and government regulatory authorities in terms of vessel safety monitoring and waterway safety regulation.

Solution

The Maritime Shipborne Video Surveillance System is based on an IP network architecture. By deploying various devices such as cameras, microphones, alarm buttons, and voice intercoms on vessels, it enables monitoring of critical internal areas and various external environmental scenes from the onboard monitoring center. The system also supports multi-level networking, realizing a two-tier architecture comprising the onboard monitoring center and the port monitoring and command center.

Solution Advantages

1) Anti-corrosion Technology

Given the characteristics of maritime vessel monitoring environments, cameras with different anti-corrosion grades are selected, offering strong environmental adaptability and saving construction costs. For highly corrosive outdoor environments on ocean-going vessels, anti-corrosion cameras with 316L stainless steel housings are chosen. For indoor areas of vessels or inland waterway vessels where corrosive sources and intensity are lower, coated anti-corrosion cameras with special external protective layers are used.

2) Local Storage and Upload upon Return to Port

This shipborne video surveillance system is designed for medium to large vessels. Their voyages are typically long, requiring extended storage duration and large storage capacity. Furthermore, the routes of medium to large vessels are often remote, making real-time transmission unfeasible from both cost and practicality perspectives. Therefore, the system is designed to store video resources locally and upload them upon return to port.

3) Professional HD Network Surveillance

The system utilizes HD cameras (1.3-megapixel, 2-megapixel) with professional image processing technology. Its defogging technology can capture clear and natural images despite the fog commonly occurring in daytime water environments. Starlight-level low-light technology ensures good image quality at night in certain water scenes with minimal supplementary lighting.
