Security system

Abstract

A multi-layered security system having an attack side, the security system comprising a plurality of barriers arranged in a spaced apart relationship with respect to each other, wherein each pair of barriers are located opposite to each other to define another barrier comprising a passage located between the pair of barriers located opposite to each other. The system can additionally comprise security defences such as anti-climb mesh, spike barriers or rollers. The system further comprises a link bar to join together adjacent panels and create barriers. The link bar comprises a means for joining together adjacent panels on both ends and maintaining the panels in a spaced apart relationship.
