Rise of the Machines

Realm of the sensors

Sensored City
City of cameras   

Rio de Janeiro may be known for its beautiful beaches, but it also has to grapple with high crime, large-scale protests, and the threat of landslides. Now, officials have put in place a cutting edge network of thousands of cameras and sensors that monitor the city around the clock in an effort to ease traffic, thwart crime, avoid catastrophe, and save lives.

From refrigerators to freight trains, CNBC's "Rise of the Machines" shows you how a new generation of connected machines can now speak to us, and each other. "Rise of the Machines" premieres Wednesday, Sept. 18 at 9 pm ET/PT.
