Web Based Access Systems• Definition of Web Based Access Control System
– Access Control application that can be accessed entirely from a standard Web Browser (ie, Internet Explorer, Mozilla Firefox)
• 3 Types of Web Based Systems– Traditional host based system with web interface add-on– Web hosted application such as an ASP model– Browser based network appliance
• What is an Appliance?– Special purpose hardware platform with embedded
software that handles a particular application (ie, Linksys router, IP camera, chiller plant controller)

Industry Trends – Access Control• Progression of Access System Architectures
– Host based server, client workstations– Master server, regional servers, client workstations – Embedded access systems, web browser based clients
• Traditional Access System Architectures are Changing– Network topology is flattening– Systems becoming more distributed
• Open Integration for Access Systems– Previously through custom proprietary serial drivers– Can also provide connectivity through API / SDK– Migrating towards open protocols – BACnet, LON, Modbus,
Niagara– Now deliver content through web services – XML, oBIX

Industry Trends - BAS• Facility Managers Seeking Tighter Integration with
Lighting, HVAC, and Energy Management– Need for energy cost savings!!
• Access System Becoming Vital Component of BAS– Provides “who” enters the facility– Based on “who”, system can determine “where” individual
lives and “what” resources they require
• Facilities can Exact Equipment Usage Based on Need– Reduces energy costs– Increases life expectancy on equipment– Track “who” and how much energy was consumed

Enterprise Integration• Business applications need security and building
information• Web based access systems combined with Web
Services provides the plumbing to unlock this information
• New Enterprise applications are now possible such as – After hours tenant billing– Individual tenant comfort override and personal settings– Integrated “smart building” scenarios – the building simply
knows what to do when you present your card

Issues:• Traditional access systems are not embedded systems
– Required host based servers– Required Client workstations with thick client software
• Traditional access systems not integrated in to Building Automation Systems – Standalone and isolated systems– Inefficient use of equipment and energy
• Limited Enterprise Integration– Lacking the “who” and the “what”– Money left on the table

Benefits of Next Generation Access Systems • Embedded, browser based
– Full server functionality without the PC or Disk drive– Less intimidating investment
• More customers will invest in high tech security without the need for high tech training
– Lower maintenance cost– No single point of failure – System can be sold with the building– No special operators software or PC
• Any browser is an operator station• Access from anywhere for daily operation and maintenance
22
Benefits of Next Generation Access Systems• BAS Integration
– Lower installed cost of integrated systems vs. stand alone systems with overlapping features
– Increased energy savings with tighter integration of occupancy for lighting and HVAC
– Increased tenant satisfaction with “one card swipe” integrated control of security, lighting, and HVAC
– Easy tenant override• Enterprise Integration
– Integral oBIX server lowers cost of integrating security data to the enterprise
– No server PC required, big system functionality without the big system
– Occupant and override data tightly integrated to enterprise applications for tenant billing, human resources etc.
