An electric fence is a barrier that uses electric shocks to deter humans and other animals from crossing a boundary. Most electric fences are used for agricultural purposes and other non-human animal control. They are also commonly used to protect high-security areas such as military installations or prisons, where potentially lethal voltages may be applied. Virtual electric fences for livestock using GPS technology have also been developed.

Electric fence in the context of Removal of Hungary's border fence with Austria
The removal of Hungary's border fence with Austria occurred in 1989 during the end of communism in Hungary, which was part of a broad wave of revolutions in various communist countries of Central and Eastern Europe. The border was still closely guarded and the Hungarian security forces tried to hold back refugees. The dismantling of the electric fence along Hungary's 240 kilometres (149 mi) long border with Austria was the first fissure in the "Iron Curtain" that had divided Europe for more than 40 years, since the end of World War II. Then the Pan-European Picnic caused a chain reaction in East Germany that ultimately resulted in the demise of the Berlin Wall.

A prison escape (also referred to as a bust out, breakout, jailbreak, jail escape or prison break) is the act of an inmate leaving prison through unofficial or illegal ways. Normally, when this occurs, an effort is made on the part of authorities to recapture them and return them to their original detainers. Escaping from prison is also a criminal offense in some countries, such as the United States and Canada, and usually results in time being added to the inmate's sentence, as well as the inmate being placed under increased security that is usually a maximum security prison or supermax prison. In Germany and a number of other countries, it is considered human nature to want to escape from a prison and it is considered as a violation of the right of freedom, so escape is not penalized in itself (in the absence of other factors such as threats of violence, actual violence, or property damage).
Many prisons use security features such as CCTV, perimeter sensors, barred windows, high walls, barbed wire, razor wire, and electric fencing to prevent escapes. Even natural geographic features can play significant roles in preventing escapes; historically, mountains and islands were chosen as ideal settings for prison construction, given their significance in creating territorial isolation from outside worlds.
