Fenced-in areas, such as airports, nuclear power stations, industrial sites, or private plots of land, can now be monitored thanks to novel sensor technology that has been developed by a team of experimental physicists. The sensors respond immediately as soon as someone tries to climb over or cut through the fence, providing information on the precise location of the security breach. They are even able to detect a low-flying drone passing overhead.
