ut the processing and further use of such data." 7.4.2 Surveillance Legality Wayne Crews, director of technology studies at the Cato Institute, a public policy research organization located in Washington, isn't overly concerned by business and homeowners using surveillance cameras to protect their prop- erty. "A burglar doesn't have an expectation of privacy," he notes. "You're free to look out your front window at your neighbor's front lawn, but you can't go into his yard and look into his windows." Local jurisdictions, however, can limit the surveillance of people working inside a business or home, particularly if the workers are unaware that such monitoring is taking place. Crews is also very worried about the increasing adoption of wireless camera technology by police departments and other government agencies, particularly when such cameras are connected into information databases. "The rules of the game are not written regarding the use of these kinds of perpetual surveillance capabilities," he notes. "It's going to be the privacy fight of the future." On the other hand, Crews is supportive of individuals using phone cameras to record instances of unlawful government and corporate activities. "If the THE SEEING EYE eyes are being turned on us by these kinds of technologies, we're turning the eyes right back on corporations and the government," he says. 7.4.3 Security Video Network Wireless video sensor networks have the potential to significantly enhance national security and emergency response efforts. Assistant Professor Thomas Hou and Professor Scott Midkiff of Virginia Tech's electrical and computer engineering department are studying factors that affect network lifetime. Composed of interconnected, miniature video cameras and low-power wireless transceivers that process, send, and receive data, wireless video sensor networks can provide real-time visual data in situations where accurate surveillance is critical, says Hou, the project's principal investigator. These networks can help reduce the impact of
