Virtual Wall

A 28-mile virtual fence is rising along the border. It comes in the form of nine nearly 100-foot-tall towers with radar, high-definition cameras and other equipment. Known as Project 28, for the 28 miles of border that the towers will scan, the so-called virtual fence forms the backbone of the Secure Border Initiative, known as SBInet, a multibillion-dollar mix of technology, manpower and fencing intended to control illegal border crossings. However, the viability of a high-tech barrier to detect illegal border crossers remains uncertain, after a pilot project struggles.
