U.S. begins beefing up Canadian border security

High above the rugged border, an unmanned Predator B drone equipped with night-vision cameras and cloud-piercing radar scanned the landscape for signs of smugglers, illegal immigrants or terrorists.

Armed agents checked the identification of border crossers while radiation sensors and other devices monitored vehicles entering by road. Soon, a new network of telescopic and infrared video cameras mounted atop 80-foot-tall metal towers will rise above critical locations.

The beefed-up border security is not taking place along America’s chaotic southern border – riven by drug smuggling, gun running and illegal immigration – but, rather, its traditionally boring northern boundary with Canada.
