High-level Objectives:

A short and non-exhaustive list of reasons to use an integrated  control system include:

  • simple, consistent user experience for operation of AV systems and their individual components
  • achieving cohesion by integrating disparate AV devices so they perform effectively as a unified system operated by a single user interface
  • integration with building management systems (BMS)
  • integration with Emergency Warning and Intercommunication System (EWIS) 
  • achieving energy-saving goals by switching devices off or into standby mode through scheduling and automated processing

A control systems may also be utilised for advanced applications:

  • reporting and analytics for asset management
  • system faults and warning notifications (e.g. text message, email, or log file)
  • integration with room booking system (e.g. session start/end notifications)
  • dynamic and contextual user guide integrated into graphical user interfaces
  • enterprise-grade control processing server software as a centralised ICT architecture alternative to traditional appliance-based control processing solutions


Specific Room Functionality:

Common examples of AV system control found in an educational space:

  • switching a source device to one or many output destinations
  • control of individual source devices, e.g. pan/tilt/zoom (PTZ) cameras, visualisers
  • volume and mute control of audio sources (including microphones) and destinations
  • automatic startup or shutdown of systems based on occupancy and/or schedule
  • lecture recording control and system feedback
  • automated and manual control of lighting and motorised blind systems
  • control of mains power delivery to meet energy-saving goals (eg. by turning off 240-Volt power to amplifiers at midnight, and restoring power at 7am)
