PHOENIX (AP) - A Senate committee has approved a bill that would allow Arizona to build a "virtual fence" along the Arizona-Mexico border.
An amendment to House bill 2462 would allow the state to place high-technology radar and video sensors on 300 towers along 375 miles of the border to monitor human and drug-smuggling activity. The sensors would send signals to a publicly accessible site and could also be monitored by law enforcement agencies.
The federal government tried to construct a "virtual fence" along the border in 2006 but abandoned the project in 2011 after spending more than $1 billion on a faulty system.
The fence would cost about $30 million but the bill approved Tuesday with an 8-1 vote does not appropriate any funds.
