Robotic Nation Evidence

Home, Secure Home: "Twice a day, a drone helicopter flies along the perimeter of the property, surveying the landscape with a pair of wireless camera 'eyes.' Robot security guards patrol the grounds. Visitors who show up at the enforced steel door at the center of the property must present a biometric passport and submit to an iris scan. Inside, computers and security personnel track the identities of visitors as they move from one room to the next. These aren't precautions at a supersecure government site, but the latest defenses available to the well-heeled homeowner. Security technology once the reserve of government agents is fast becoming a part of everyday civilian reality�for those who can afford it."
