can be two-way. For example, technical personnel can be notified via email of
an alarm or a maintenance event for a particular AV component, such as a
burned-out projector bulb (Fig. 15.3).
Beyond system administration, management and monitoring through data
networks, audio visual systems have increasingly incorporated the digital crea-
tion, sourcing, transport, display and storage of audio and visual signals. The
wide variety of components and the types of cable interconnections means that
adopting smart building technologies for audio visual systems is more complex
than other technology systems.
