ICx officials say the shipments of their Cerberus unmanned mobile surveillance technology, part of a $4 million order, will go to support the U.S. Customs and Border Patrol's operations along the U.S.-Mexican border.

The Cerberus units offer Border Patrol officers mobile surveillance towers with advanced radars and camera technology that company officials say enhance the ability to identify and track potential suspects attempting to cross the border as part of a "virtual fence," the release said.

"Border Patrol agents face tough challenges in making our borders safer," Adam Strange, ICx Tactical Platforms president, said in a statement.

"Technology, deployed well, can play an important part in assisting our agents in making that happen. We are glad to be an integral part of Customs and Border Patrol's focus, and of being the first to provide them with a working solution to this important challenge."
