The legacy stand-alone security systems are transforming into intelligent-computerized-network based building automation systems. This paper presents the outcomes of a Post-Graduate Level Project, that aims to develop working pilot models for security as well as for complete automation of a residential building and complex respectively, based on wired networking technology. The paper describes design and implementation of wired security system and wired building automation system along with necessary theoretical background. Development of web-based virtual instrument to run-time couple local/remote monitoring and control of the building has been major outcome. The presented designs have been re-usable with need based customization, simple, user-friendly and validated through implementation. (C) 2015 Elsevier B.V. All rights reserved.
