In the latest border technology initiative, officials will tailor plans to fit different stretches of the geographically diverse border by selecting from a menu of technology. Here are descriptions of the items on the menu:

Night-vision goggles provide agents with a long-range infrared image of the desert floor.

Agent-portable surveillance systems include a tripod-mounted, long-range infrared sensor and camera, plus a battery and a laptop. They can be carried by two to four agents into mountainous or remote areas.

Helicopters, airplanes and unmanned aerial systems help agents patrol mountains, canyons and other remote areas that are difficult to reach on foot or by car.

Motion sensors: Some are buried, some trigger a camera; both send a signal to a central command center.

Truck- mounted mobile surveillance systems have infrared cameras and radar displaying sensor information in the cab of the truck. Ideal for hilltops.

Integrated fixed towers have cameras and radar that collect and send images and information to command centers. These include towers from the scrapped virtual fence as well as new ones.

Remote video surveillance systems are pole-mounted day-and-night cameras mostly used close to urban areas.
