From Anchorage it takes 90 minutes on a propeller plane to reach this fishing village on the state's southwestern edge, a place where some people still make raincoats out of walrus intestine.

This is the Alaskan bush at its most remote. Here, tundra meets sea, and sea turns to ice for half the year. Scattered, almost hidden, in the terrain are some of the most isolated communities on American soil. People choose to live in outposts like Dillingham (pop. 2,400) for that reason: to be left alone.

So eyebrows were raised in January when the first surveillance cameras went up on Main Street. Each camera is a shiny white metallic box with two lenses like eyes. The camera's shape and design resemble a robot's head.

Workers on motorized lifts installed seven cameras in a 360-degree cluster on top of City Hall. They put up groups of six atop two light poles at the loading dock, and more at the fire hall and boat harbor.

By mid-February, more than 60 cameras watched over the town, and the Dillingham Police Department plans to install 20 more — all purchased through a $202,000 Homeland Security grant meant primarily to defend against a terrorist attack.
