The Trump administration has begun installing a network of camera towers along sections of the U.S.–Mexico border aimed at giving Border Patrol agents real-time electronic alerts when sensors detect unauthorized crossings. Officials involved in the rollout say the equipment is designed both to deter would-be migrants, who can see the towers from a distance, and to channel those who attempt to cross into areas where agents can respond more quickly. Supporters inside the administration argue that the additional surveillance capacity will cut the time agents spend searching remote terrain and, over the longer term, help reduce the immigration-court backlog by curbing the number of people who enter the system. Details on the total cost, the number of towers to be deployed, and the specific contractors involved have not yet been released.
