PA through IP Paging

Description

The concept of making a public address or paging announcement is very simple and has not changed in decades: select where you want the message to be heard and then speak into the microphone. Dedicated Long Line wiring takes the signal to the amplifier and on to the selected loudspeakers.

Implementing PA over IP does not change this greatly; the difference is in how the signal is transported, the physical distance that announcements can span (the entire Planet!) and increased flexibility in being able to dynamically create paging zones and to simply add extra PA endpoints without major cost or inconvenience.

With IP Paging / PA systems there are:

• Input devices: A PC running the Digital Message Streamer firmware; these are used to encode the announcement (a process known as analog to digital conversion)  and put it onto the network, targeted for the selected locations
• Output devices: To receive the messages and play them

• Build a complete IP based Public Address / Paging system
• Allow remote input to an existing PA system
• Connect multiple, distinct PA systems into a single, unified system; for example linking all existing building PA systems in a college to create a campus-wide notification system.

It improves on traditional public paging by offering the ability to target messages to specific telephones and corridors. This allows to communicate with everyone at one time or to target specific groups or individuals. IP Paging provides a common system for public address announcements, emergency broadcasts, bell scheduling, and text notifications. Unlike older paging systems, which send an audio message to all speakers within the paging system, IP Paging allows audio messages (as well as text messages) to be sent to individual speakers, predefined groups of speakers, telephones, or PCs
