Author: Brian Rhodes, Published on Aug 28, 2013

Fences, while a low tech barricade, are a cornerstone of good security. Few physical security elements are as effective at keeping threats away as security fences. While simple and familiar, which types are the best for a given situation? In this note we survey the major types used in security today, how they are specified, and the relative cost of those options.
