A decade after the Sept. 11, 2001, attacks on the World Trade Center and the Pentagon, federal and state governments are spending about $75 billion a year on domestic security, setting up sophisticated radio networks, upgrading emergency medical response equipment, installing surveillance cameras and bomb-proof walls, and outfitting airport screeners to detect an ever-evolving list of mobile explosives.

One effect is certain: Homeland Security spending has been a primer-pump for local governments starved by the recession, and has dramatically improved emergency response networks across the country.

An entire industry has sprung up to sell an array of products, including high-tech motion sensors and fully outfitted emergency operations trailers. The market is expected to grow to $31 billion by 2014.

Like the military-industrial complex that became a permanent and powerful part of the American landscape during the Cold War, the vast network of Homeland Security spyware, concrete barricades and high-tech identity screening is here to stay. The Department of Homeland Security, a collection of agencies ranging from border control to airport security sewn quickly together after Sept. 11, is the third-largest Cabinet department and — with almost no lawmaker willing to render the U.S. less prepared for a terrorist attack — one of those least to fall victim to budget cuts.

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.
