Aiphone Corporation, U.S. headquarters in Bellevue, Washington (parent Aiphone Co., Ltd. headquartered in Nagoya, Japan since 1948), is the largest commercial intercom manufacturer in the North American market. The Aiphone catalog is organized around six primary product lines covering every intercom deployment scenario: IX Series (enterprise IP intercom with SIP integration for commercial and multi-tenant), GT Series (multi-tenant residential IP and analog call panels for apartments and condos), JO Series (single-family residential video intercom), LEM/LEF Series (simple two-unit analog intercom for home office, garage, or small retail), AX Series (integrated security intercom with card reader and relay outputs), and IS Series (IP commercial intercom with video, audio, and master station support).
Aiphone's market position in North America is built on two decades of deployment reliability in institutional environments — K-12 schools (GT or IX multi-tenant for student entry verification), hospitals (IX at emergency entrances, nurse stations, and staff corridors), commercial office buildings (IX with GT multi-tenant at lobby entries), and government buildings (IX Series with SIP integration for visitor management). Aiphone is the default specification when a commercial intercom needs to just work reliably for 10-20+ years without manufacturer roadmap changes or product discontinuations.
Aiphone IX Series integrates natively with SIP-based phone systems (Cisco CUCM, 3CX, Avaya, Mitel) and major access control platforms (LenelS2, Genetec, Paxton, Honeywell Pro-Watch) — enabling unified intercom + access control + VMS workflows in enterprise deployments. Aiphone is NDAA Section 889 compliant (Japanese manufacturing) and approved for U.S. federal procurement.
