(CNN) -- When her baby girl takes an afternoon nap, or on those nights when she just can't sleep, Sarah Andrews, 32, tosses off her identity as a suburban stay-at-home mom and becomes something more exotic: a "virtual deputy" patrolling the U.S.-Mexico border. A Texas program lets Internet users around the world monitor live video from the Mexico border. From her house in a suburb of Rochester, New York, Andrews spends at least four hours a day watching a site called BlueServo.net. There, because of a $2 million grant from the state of Texas, anyone in the world can watch grainy live video scenes of cactuses, desert mountains and the Rio Grande along Texas' portion of the international border.
