Secure Traffic Signal Control and CCTV Monitoring in a Harbor

Introduction

When the monitoring system along a key harbor corridor in a major American city needed updating, the system manager decided to use existing copper wiring to transmit data over significantly longer distances. As this project needed to integrate more systems into one network, serial networks were no longer sufficient to support the expanded network, which is why an industrial Ethernet technology over copper wires via a DSL was required to support more bandwidth over longer distances. In addition, VPN connections and firewall protection were required to ensure network safety and data integrity.
