PA over IP refers to PA paging and intercom systems that use an IP network instead of a centralized amplifier to distribute the audio signal to paging locations across a building or campus, or anywhere else in the reach of the IP network (including the Internet).

Network-attached amplifiers and intercom units are used to provide the communication function. At the transmission end, a computer application transmits a digital audio stream via the local area network, using audio from the computer’s sound card inputs or from stored audio recordings. At the receiving end, either specialized intercom modules (sometimes known as IP speakers) receive these network transmissions and reproduce the analog audio signal. These are small specialized network appliances addressable by an IP address just like any other computer on the network.

Such systems are inter-connected by the networking infrastructure and thus allow loss-less transmission to remote locations across the Internet or a local area or campus network. It is also possible to provide for multiple or relocatable transmission control stations on such a network.

Secure and safe communication systems are indispensable in work sites where personnel wearing protective clothing and gloves are working. Such systems must operate even in the most severe environments.

Also, the system must offer high-quality calls and clear broadcasts that overcome the background noise from machines and outdoors.

We, offer system solutions, such as staff announcement, emergency broadcast, and evacuation guidance, to plants handling volatile substances, such as oil refinery, natural gas and fertilizer.

System Integrated with Voice Evacuation System
Voice is heard from all of the speakers and the station speakers if emergency paging is performed from the voice evacuation system in addition to the stations. An integrated communication system allowing various interface units and stations to be connected with local area networks (LAN), wide area networks (WAN), and optical fiber networks (OFC).

A suitable communication system can be built that includes contact output control and external equipment control in association with calls and calling as well as calls, calling broadcasts and BGM broadcasts.
