NEWARK (Fox) – There are new LED lights greeting passengers at Newark Liberty International Airport’s Terminal B but they do more than illuminate; they also are part of a security system that is watching you before you even get to the security checkpoint.

The lights are fitted with computer chips, cameras, sensors and wi-fi antennas. They collect data that can help detect suspicious activity or aid in police investigations.

Currently, the lights are only near the ticketing counters of the one terminal but the Port Authority of New York and New Jersey, which operates the airport, is considering expanding the pilot program to other terminals.

Advocates say the lighting systems can be used for a variety of useful applications. But others say the collection of more and more data raises privacy concerns.

The system also can aid in moving people and cars by identifying long lines.
