The HPSA-8100-R series delivers live and pre-recorded announcements originating from WoIP integrated base station (IBS) via secure, robust and reliable Ethernet communications network devices, IP Communicators (IPC2). The IPC2 sends and receives audio via an RTP multicast stream through the Local Area Network. Eaton approved radios (RADIO-500G and RADIO900M) can be added to provide wireless communications. Both the IPC and radios support the highest standards of network security and encryption. The HPSA-8100-R series can also be used to expand outdoor coverage in an existing 2.4 GHz WAVES system by upgrading the IBS and adding IP capability.
