From the text of the bill:
"1) systematic surveillance of the international land and maritime borders of the United States through more effective use of personnel and technology, such as unmanned aerial vehicles, ground-based sensors, satellites, radar coverage, and cameras; and
(2) physical infrastructure enhancements to prevent unlawful entry by aliens into the United States and facilitate access to the international land and maritime borders by United States Customs and Border Protection, such as additional checkpoints, all weather access roads, and vehicle barriers."
They specifically mention wicked technology including UAV's, satellites, cameras, and ground sensors. I am against the idea of only a wall. This bill will impress you if you take the time to read it.
Thank you.
