Automated video surveillance promises to increase the safety of tunnels used by road traffic and reduce tunnel operating costs at the same time. An Austrian firm named Center Communication Systems (or "Center Systems" for short) won some major new customers within just a few months of launching a new version of its tunnel surveillance package VBTC Tunnel (Video-Based Traffic Control). The application features new algorithms, an improved single-frame method, and an intelligent alert management system. Powerful hardware is an essential prerequisite for running a powerful image-processing application. Since harsh environmental conditions can exist in tunnels, it is not possible to use just any computer for them. In the new systems, CompactPCI boards made by Kontron are utilized.
