In the main office of the Border Police HQ of Copenhagen Airport, a screen presenting a black and white still-image of the border zone floor becomes animated when a person moves into the area. "3D people tracking sensors" in the ceiling identify a presence and a small white dot starts moving across the image. If the person queues up in front of the manual passport control, the dot turns bright red. If the person slows down by the ABC (Automated Border Control), the dot turns blue. White is movement, movement is good. At present, the many red and blue dots have turned into big blobs, indicating that too many people are queuing in the passport control instead of lingering in the shopping areas or reaching their flights. But in the Police HQ, no one looks at the screen, except the anthropologist, fascinated by the aesthetics of the imagery, the small moving dots that change colour, and by the fact that the border control guards are themselves being controlled. The border guards, on the other hand, don't need the screen to know when people are crowding, they can hear it through the thin walls, see it from the "aquarium" and sense the bustle. But the red and blue dots are registered and audited in the offices of "CPH Airport", the private company owning and running the entire airport complex, and the data will be used in the next negotiations with police management and Frontex about increasing flow and reducing retention on the Schengen border.
