G Element was invited to present on the topic of Converging Real-time Sensor Networks with 3D Building Models for Integrated Security, Building and Enterprise Management at the BIM seminar organized by BCA on 30 Nov 2012. In this talk, we share on the different types of modern-day sensor sub-systems for smart buildings today and how we can unify maps, sub-systems and situations to provide a 3D unified management system to the end-users.
