US Dept of Homeland Security develop a 'Container Security Test Bed' to facilitate research on container surveillance. The DHS Science and Technology Directorate (S&T) and its Transportation Security Laboratory (TSL) in Atlantic City, NJ, have developed a way to test technical solutions to the need to find out quickly what's in a container. The Container Security Test Bed (CSTB) – an outdoor “laboratory” allows researchers and developers from government, academia, and industry to explore novel ways to detect threats in a cargo container.
