SVILENGRAD, Bulgaria — The infrared cameras here near Bulgaria’s borders with Greece and Turkey are high powered enough to pick up rabbits scampering across farm fields in the dead of night.

But on a recent afternoon, the men inside the border station were focused on a car — moving a bit too fast along a country road. Maybe a smuggler, they thought. They called over their radios to have the car stopped. It turned out to be a false alarm.

Bulgaria and its neighbor Romania, which has spent more than 1 billion euros, developing an equally high-tech border operation, are hoping to join the European Union’s visa-free travel zone this month. They also hope to take over guarding some of the union’s outer borders.

Both Bulgaria and Romania were welcomed into the European Union in 2007, despite lingering questions about organized crime, corruption and an ineffective judiciary. Now, however, as Europe faces an economic crisis, fear of more immigration from Africa and growing nationalistic fervour among member countries, it is paying more attention to these issues.
