Algo 8028 SIP Doorphone (Controller + Intercom) – Secure PoE IP Door & Gate Access Control for EntrancesThe Algo 8028 SIP Doorphone (G2) is a two-piece IP intercom solution built for secure visitor entry at doors, gates, and access points. The outdoor-rated intercom station handles clear two-way communication while the separate indoor controller keeps the network connection and door relay completely protected from tampering. Powered by PoE (or PoE+ for higher strike power), it delivers wideband HD voice and works with virtually any hosted or on-premise VoIP/UC platform – no FXS port or ATA required. Whether you’re upgrading legacy analog intercom wiring or installing new, the single twisted-pair connection (up to 1,000 ft) makes deployment simple and cost-effective. The Telecom Spot Expert Take: For IT managers and facility teams who need reliable, secure visitor communication without exposing the network or door controls, the Algo 8028 stands out as a smart, future-proof choice. The two-piece design (outdoor station + indoor controller) eliminates common tampering risks that plague single-unit doorphones. Wideband G.722 audio cuts through noise for crystal-clear calls, while the backlit call button and NEMA 3R rating handle real-world weather and low-light conditions. We see the biggest wins in mixed-use facilities where quick retrofit of existing wiring saves thousands in labor – plus the RESTful API and multicast options give advanced users extra flexibility. If your team wants plug-and-play SIP integration with Microsoft Teams, Zoom, or RingCentral and rock-solid access control, this is the unit that consistently delivers. Key Features Secure two-piece design – Intercom station stays outside while the controller (with relay) stays safely indoors, preventing tampering with network access or door strikes. Hands-free wideband HD voice – G.722 codec delivers clear, intelligible speech even in noisy environments like warehouses or busy entrances. Keypad-activated door/gate control – During a call, any phone keypad can send a DTMF code to momentarily unlock the door or gate – configurable duration keeps security tight. Easy retrofit with existing wiring – Single twisted-pair (24 AWG) connection runs up to 1,000 ft, perfect for upgrading legacy analog intercoms without new cabling. Outdoor-rated durability – NEMA 3R/IP66 stainless steel faceplate, weatherproof mylar speaker, and conformal-coated circuitry stand up to rain, dust, ice, and temperature swings (-40 °F to +122 °F). PoE/PoE+ powered – Simple network deployment with optional 24V DC backup; supports up to 500 mA strike power when using PoE+. Full SIP compatibility – Secure TLS/SRTP, multicast receive (50 zones), RESTful API, and auto-provisioning for seamless integration with any modern UC platform. Door sensor input – Detects open/closed status to prevent tailgating and adds extra security layers.
