Abstract

A modular unit for constructing a barrier, where the modular unit can fully or partially be manufactured in a factory for transport to the location of the barrier, with the modular units having a base and at least a pair of wall panels installed on the base. The modular units are assembled into the barrier by placing the modular units side-by-side along a line or curve on a mounting surface. The modular units are designed with features to prevent climbing or scaling over the barrier and support electronic and power equipment to protect and monitor the protected location.
