"U.S. Customs and Border Protection (CBP) deploys land-based surveillance technologies to help monitor and secure the border and apprehend individuals who attempt to cross the border illegally. GAO [Government Accountability Office] has reported on the progress and challenges DHS and its components have faced implementing its border security efforts. This statement addresses (1) the status of CBP efforts to deploy land-based surveillance technologies along the southwest border and (2) CBP's efforts to measure the effectiveness of these technologies. This statement is based on GAO reports and testimonies from 2011 through 2016, selected updates conducted in 2017, and ongoing work for this subcommittee related to border surveillance technology. For ongoing work and updates, GAO analyzed technology program documents; interviewed DHS, CBP, and U.S. Border Patrol officials; and conducted site visits to Arizona and Texas to observe technologies. GAO has made recommendations to DHS to improve its management of plans and programs for surveillance technologies. DHS has generally agreed. DHS has taken actions or described planned actions to address some of these recommendations. GAO continues to believe that these recommendations could strengthen CBP's management efforts and will continue to monitor CBP's efforts."
