DALLAS – At a terminal being renovated here at Love Field , contractors are installing 500 high-definition security cameras sharp enough to read an auto license plate or a logo on a shirt.
The cameras, capable of tracking passengers from the parking garage to gates to the tarmac, are a key first step in creating what the airline industry would like to see at airports worldwide: a security apparatus that would scrutinize passengers more thoroughly, but less intrusively, and in faster fashion than now.
It’s part of what the International Air Transport Association , or IATA, which represents airlines globally, calls “the checkpoint of the future.”
The goal is for fliers to move almost non-stop through security from the curb to the gate, in contrast to repeated security stops and logjams at checkpoints.
