Video Surveillance System for Seaports

 

Introduction

As the transfer point between land and sea transportation, seaports play a critical role in the global economy. Harbors combine the major operations of large-scale shipment, storage, and transportation, and a seaport surveillance system must be on a large scale as well, covering roads, ports, docks, bonded areas, container yards, and shipping areas.

For this particular video surveillance system, different areas required different levels of access and control to the surveillance system. Certain areas also required an emergency communication system to contact the control center. The system was characterized by the following:

Long distances between each area
Hazardous environments
Multi-level infrastructures
Data, voice, and video integration

In order to ensure maximum reliability, it was critical that redundancy was incorporated into all subsystems and into the entire system architecture.
 
System Requirements
High reliability
Wide bandwidth
High flexibility
Data, voice, and video integration
Industrial-grade video server for CCTV integration
IP surveillance software for multiple video controls and monitoring
Rugged design for outdoor environments

 

System Description
Different levels of control authority were assigned to the main control center and sub monitoring rooms (Rooms 1 through 4). The main control room could simultaneously control, record, and monitor all other rooms. Each sub monitoring room had control of its own camera but not of other rooms.

Networking Infrastructure
An industrial Gigabit Ethernet network was used to ensure enough bandwidth for all video, voice, and data information. The EDS-828 Ethernet switch was used in the main control room for the redundant network backbone, which used a Gigabit Turbo Ring topology. The subsystems also used the EDS-828 for local fiber optic rings. Additional Gigabit ports were used for uplinks and ring coupling, to connect other nodes or Turbo Rings at Gigabit speeds.

Video Networking Infrastructure
The VPort 351 was used to connect analog CCTV cameras to the network for remote video surveillance monitoring. Fiber optic media was used to connect the VPort to the EDS-828 over long distances. Moxa's SoftDVR Pro software was installed in the main control room for simultaneous real-time control, monitoring, and recording of multiple remote video feeds.
