The camera network – using software from 3VR Security Inc., a San Francisco company that makes surveillance technology – already knew what the houseman looked like; facial recognition algorithms had built a profile of him over time. With a couple of mouse clicks, managers combed through hours of videotape taken that night by the hotel’s 16 cameras, and found every place he had been – including the back entrance he slipped out of, three hours into his shift. He became 1 of 10 employees dismissed from the hotel since 3VR’s surveillance package was installed last June.
