Tunnel Security Project

In the aftermath and as a consequence of a catastrophic 2001 tunnel fire and events of 9/11, designed, developed and deployed two turnkey automated remote-access security and surveillance systems at a rail tunnel portal located in Baltimore, MD (location cannot be divulged). A combination of intelligent technologies was used to develop the system. This system is typical of Duos' approach to critical high-risk tunnel security.

The system is designed to automatically detect intruders and suspicious objects left behind (or removed) within a user defined video security zone. A network of fixed and PTZ day/night color and black and white digital video cameras are connected via single mode fiber to a central head end hosting Duos' proprietary rvspro™ video servers. Each rvspro™ includes Praesidium® vision suite intelligent software that processes the live video feed and creates a video digital archive. The rule-based Praesidium® discriminates between authorized vehicle traffic (trains, high rails, etc.) and intruders, and automatically deploys audio and visual alarms locally as well as at the operations communication center (OCC), or to any user connected via virtual private network to the system. A customized, intuitive Graphic User Interface (GUI) allows simultaneous viewing of live video, operation of PTZ cameras, and monitoring of the entire security system by operators located variously within the organization. In addition to the automated intrusion alarm functions, the system includes visual and multi-language audio annunciations upon perimeter breach, multiple sensing technologies, advanced heat detection, high capacity lights, IR Illuminators, amplified speakers, and strobe lights.

This comprehensive automated system is monitored 24/7/365. Duos provides like on-site maintenance and technical support as well as remote technical support. All system updates and security patches to the operating systems are uploaded remotely as soon as released.
