Aiphone's IPW-1A network intercom adaptor offers high-quality communication over TCP/IP based networks. Designed specifically for use with new or existing LAN or WAN infrastructure, the intercom functions with the supplier's IE series door stations, enabling end-users to use PCs as intercom masters. An infinite amount of intercoms and PCs can be used to create a large or small communication network. Each unit includes the supplier's "CommuniCenter" software for remote door release, group calling, event logging and audio recording.
