At Modern Spaces in New York, CEO and founder Eric Beniam said the brokerage is now exploring how to install Google Nest cameras in all of its new development projects. His hope is that a prominently displayed camera will make someone "think twice" before they act - Beniam added that he consulted lawyers to ensure the measure wouldn't be a violation of privacy.

"I think having a camera over there, the agents and [clients] will feel comfortable," he said. "We're living in crazy times. You got to do what you got to do."
