Texas has begun testing a Web site that enables anyone with Internet access to keep watch on the state's border with Mexico.
Only eight out of dozens of cameras planned for the $5 million project were operating yesterday. They showed US Border Patrol cars, trees, the Rio Grande River and an occasional cow.
Republican Governor Rick Perry has made securing the state's 1,254-mile (2,000-km) border with Mexico a major part of television ads in his re-election campaign.
The cameras at www.texasborderwatch.comwill also be equipped with night vision lenses for 24-hour surveillance.
A yellow button on the site reads "Report Suspicious Activity." Clicking the button sends an e-mail to the Texas Department of Public Safety.
"It's another step toward having a police state," said Jaime Martinez, national treasurer of the League of United Latin American Councils.
"Pretty soon they're going to be coming into our homes and we're going to have to start giving them permission, and we can't have that."
Mr Perry said when announcing the program in June, "I look at this as no different from the neighborhood watches that we have had for years and years."
Shannon McCauley, head of the Texas Minuteman group, which carries out volunteer patrols of the border, declined to comment on the Web cams.
