As maritime operations become increasingly digitalized, CCTV systems are essential for maintaining real-time situational awareness and safety across various onboard environments, including engine rooms, weather decks, and cargo areas. These systems not only depend on cameras and software, they also require reliable, high-bandwidth network infrastructure. This infrastructure must deliver low-latency performance for HD video, provide Power-over-Ethernet (PoE) to deliver power and connectivity to devices in hard-to-reach areas, and withstand harsh maritime conditions like vibration, salt exposure, and extreme temperatures.

Key requirements for surveillance infrastructure include compact hardware for space-constrained areas, cybersecurity measures to safeguard converged IT/OT systems, and redundancy to ensure uninterrupted surveillance. This application highlights the importance of using marine-certified networking devices—such as managed Ethernet switches and secure routers—to ensure continuous operation and enable secure remote connectivity via DMZ segmentation and firewall protection.
