The need for security is almost as old as mankind itself. As technology has evolved with mankind, so too have the methods and systems of security evolved, integrating technology as needed. This has continued into present day, with security systems converging onto the network and its cabling infrastructure at an increasing rate. However, as the systems used within security have become more complex due to utilizing the benefits of the network, so too has the cabling infrastructure to address both communication and security requirements. Little has been written to support this convergence of security and cabling infrastructure, until now. BICSI 005 bridges the two worlds of security and communications by providing the security professional the requirement and recommendations of a structured cabling infrastructure needed to support today's security systems while providing the cabling design professional information on different elements within safety and security systems that affect the cabling infrastructure design. BICSI 005 also provides information on the concept of "direct attach" and how it may be used within many forms of ESS systems.
