Vehicle Gate Access Control

Author: Brian Rhodes, Published on Aug 05, 2013

Delivering Vehicle Gate Access Control demands integrating a myriad of different systems. Everything from high voltage electrical, to concrete modification, trenching, welding, (extra) low voltage systems (<50 volts), to manual labor is required to accomplish a fundamental task of access: keeping the bad guys on the outside of the fence. In this note, we examine the various facets of gate access, from design to install, and even the special equipment needed to get the job done.
