The Aiphone IX-SS-2G is a two-gang, SIP-compatible IP audio door station designed for secure and reliable communication at building entrances in commercial, industrial, and multi-tenant residential applications. This vandal-resistant station integrates directly into an IP network, enabling voice-over-IP (VoIP) communication with SIP-compatible telephones, IP intercom master stations, or softphones. Its primary function is to allow visitors to initiate a call to a designated number or extension inside the building, facilitating remote door release authorization. The two-gang design indicates it is sized to fit a standard two-gang electrical box, providing a larger interface that can accommodate additional features like a camera (in video models) or a more prominent call button and speaker.

Constructed for durability in outdoor and high-traffic environments, the IX-SS-2G features a robust, vandal-resistant stainless steel faceplate that can withstand impact and weather exposure. The integrated microphone and speaker provide full-duplex audio, allowing for natural, hands-free conversation between the visitor and the answering party. SIP compatibility ensures it can integrate with a wide range of VoIP phone systems and unified communications platforms, offering flexibility in system design and allowing calls to be routed to desk phones, mobile devices, or a centralized security desk. The unit is typically powered via Power over Ethernet (PoE), which simplifies installation by delivering both data and power over a single Cat5e/6 cable.

Installation and configuration are managed through network settings, often accessible via a web browser or dedicated configuration software. The station can be programmed with SIP account information, call destinations, and audio settings. Its IP-based nature allows for easy integration into larger security and building automation systems, enabling functionalities like scheduled locking, event logging, and integration with access control systems. The Aiphone IX-SS-2G represents a modern, network-centric approach to entry communication, combining physical robustness with the flexibility and scalability of IP technology for secure and manageable building access control.
