The focus of border security has been on stemming the flow of people through various “hot spots” – border crossings that can be secured. The idea of building a long barrier like Great Wall of China has never materialized due to both cost and the impracticality of securing rugged terrain that might include mountains and rivers. In addition, the American border includes vast areas of open space far from people and infrastructure such as power, which makes monitoring difficult, according to Dewar. Faced with long borders and limited manpower, agencies have increasingly turned to technology to detect unauthorized intrusions. They include long-range fiber-optic sensor systems such as Senstar’s FiberPatrol system. These sensors can be deployed on a fence with just a single optical cable stretched up to 10 miles. Buried RF cable sensors operate very much like radar and offer the advantage of being both out of sight and protected from the elements. “People don’t know that it’s there,” says Dewar. “So they may know a system is there, but they don’t know exactly where it is and that makes it hard to defeat. It’s very tolerant to vegetation, so it works very well for borders.” Both of these systems are able to pinpoint intrusions to within meters. If the system also is integrated with CCTV, central station monitors can point cameras in the right direction for further investigation. Border Patrol agents can then be dispatched quickly. src: https://us.sourcesecurity.com/news/articles/border-security-technologies-shoot-donald-trump-co-1090-ga.19574.html https://us.sourcesecurity.com/news/articles/border-security-...
