Rep. August Pfluger joins'Fox & Friends First' and calls out Biden's handling of border crisis The feds have turned to cutting-edge cameras developed by a virtual reality wunderkind to help them monitor the southern border -- by creating an invisible border wall. The high-tech watch poles known as Autonomous Surveillance Towers are powered by solar energy and use artificial intelligence to detect movement along a two-mile radius, sending the information in real-time to agents patrolling the area. And they're now being installed at different points along the nearly 2,000 miles of the US-Mexico border. "The ASTs are in remote locations that are difficult to reach," Border Patrol agent Joel Freeland recently told The Post. "They operate 24-hours a day and are environmentally friendly because they rely entirely on solar power." The ASTs were developed by Palmer Luckey, the 28-year-old founder and designer of Oculus VR and Oculus Rift.
