SNCF – The federated nationwide video security monitoring system

An integrated, regional video traffic monitoring system that covers the city of Paris and the Île-de-France area for the French national railway company SNCF (Société Nationale des Chemins de fer Français).
One of the world’s largest integrated IP video security systems. The SNCF system consists of over 13000 cameras and more than 500 train stations interconnected in the same overall system.

At the beginning, SNCF had integrated a regional video protection monitoring system covering the whole Île de France area, including Paris. It extended progressively in phases into the whole French territory. The video system project started at the end of 2004. Since then, the system has constantly evolved. In 2014, the IP camera and operating position deployments were in place in hundreds of stations in Île de France with over 13 000 cameras and more than 500 train stations interconnected.

The system offers real time operations throughout the network. It encodes and records video streams as well as displays video content to multiple groups of users connected to the network with various hierarchical and geographical profiles. The real time video recording system has advanced functionalities, such as dynamic loop size allocation, recording failover, crisis mode and so on. The system is transparently integrated with several third party systems ranging from cameras and alarm systems to recorders.

The SNCF video security system covers the whole Île-de-France area including the city of Paris. It has further expanded into the whole French covering area with a total of over 20 million inhabitants.
