From the face scanner that will check in some attendees to the cameras-everywhere array of digital products, the CES gadget show is all-in on surveillance technology — whether it calls it that or not.

Nestled in the “smart home” and “smart city” showrooms at the sprawling Las Vegas consumer tech conference are devices that see, hear and track the people they encounter. Some of them also analyze their looks and behavior. The technology on display includes eyelid-tracking car dashboard cameras to prevent distracted driving and “rapid DNA” kits for identifying a person from a cheek swab sample.
