An Arizona legislator wants the state to spend $30 million for a high-tech surveillance network near the U.S. border with Mexico.

Republican Sen. Bob Worsley of Mesa said the "virtual fence" consisting of 200 cameras would monitor cross-border movement to see if the federal government keeps its promises to secure the border.

Under Worsley's bill, the new surveillance system would be erected within 20 miles of the border.

The Arizona Capitol Times reported that funding for the project also could include the approximately $260,000 of donations that the state has already collected for border enforcement under previously enacted legislation.
