ButterflyMX vs DoorKing: Which Intercom is Right for Your Building?

Side-by-side overview

ButterflyMX and DoorKing solve the same business problem, letting visitors reach residents at a multifamily entry, using two fundamentally different architectures. JB Technologies installs both, and the right choice depends on the building, the property manager's tech maturity, the existing wiring infrastructure, and the budget. This page lays out the honest comparison so owners and developers can decide.

ButterflyMX is a cloud-based video intercom platform. The lobby panel is a glass-front touchscreen with a video camera; the resident receives a video call on a smartphone app; access is granted from the phone; credentials are mobile-only. There is no in-unit hardware at all, and the system runs over the internet rather than analog phone lines.

DoorKing is a traditional telephone-entry intercom manufacturer with a long install base across the United States. The lobby panel is typically a metal weatherproof unit with a directory and a keypad. The system places an audio call over either a dedicated phone line or, in newer models, over a cellular module to the resident's phone. Residents grant access by pressing a digit on their phone keypad. DoorKing panels are robust, widely available, and inexpensive on a hardware basis.

What each system actually does at the door

With ButterflyMX, the visitor presses the resident's name on a touchscreen. The resident gets a video call on the ButterflyMX app, sees the visitor live, talks to them, and taps to grant access. The interaction is identical whether the resident is at home, at work, or out of state.

With DoorKing, the visitor enters the resident's code on a keypad or scrolls a directory. The resident gets a phone call from the panel (either via the building's telephone line or via cellular). The resident hears the visitor, talks to them, and presses a digit (typically 9) on their phone to unlock the door. There is no video. The interaction works the same whether the resident is home or away because it is a normal phone call.

Wiring and infrastructure

ButterflyMX needs internet at the panel, typically category cable to the building's MDF, plus optional cellular failover. It does not need any phone-line infrastructure to the units. New construction can skip the phone-cable run entirely.

DoorKing's traditional models needed a dedicated POTS phone line at the panel. Newer DoorKing cellular models swap the POTS line for a cellular module, which simplifies install in buildings that no longer maintain analog phone service. Either way, no internet is required at the panel for the basic intercom function.

For a new construction project where the wiring is being designed from scratch, the ButterflyMX category-and-internet approach is cleaner because there are no analog phone wires. For a retrofit in a building that already has a working POTS or cellular DoorKing system, DoorKing's hardware-only upgrade path is often cheaper than tearing out the existing system.

Cloud platform vs no platform

ButterflyMX is a software-as-a-service product. The platform manages residents, credentials, amenity access, integrations with Yardi/RealPage/Entrata/AppFolio, package room workflows, virtual reception, and so on. There is a monthly subscription fee.

DoorKing in its traditional form is hardware-only. The property manager programs residents at the panel itself, or via DoorKing's accompanying management software in newer models. There is generally no monthly software fee on the core hardware product, though DoorKing's cellular and cloud-connected lines do have service plans.

For an operator managing one building who does not run Yardi or RealPage and does not need package room or amenity smart lock features, the no-subscription DoorKing model can be the right fit. For an operator running a portfolio of buildings on Yardi or RealPage who wants one platform across visitor entry, amenity access, package rooms, and resident self-service, ButterflyMX consolidates a lot of separate workflows into one platform.

Resident experience

The biggest experiential difference is video. ButterflyMX residents see the visitor before granting access. DoorKing residents hear the visitor over a phone call but do not see them. For Class-A new construction targeting tech-forward renters, the video experience is part of what the building is selling. For workforce housing or budget retrofits where the priority is reliable basic intercom function at the lowest installed cost, DoorKing's phone-call model gets the job done.

The second experiential difference is the resident app versus no app. ButterflyMX residents install the app on their phone and use it for visitor calls, amenity access, package room pickup, and so on. DoorKing residents do not install anything, visitor calls just come in as a normal phone call from a known number.

When ButterflyMX is the right choice

• New Class-A multifamily construction in Atlanta podium developments, Sandy Springs Perimeter Center, Alpharetta Avalon-area, or Smyrna Battery district
• Operators running Yardi, RealPage, Entrata, or AppFolio who want PMS integration
• Buildings with significant amenity space (gym, package room, pool, garage) where one mobile credential across all access is valuable
• Tech-forward property managers who want video verification and remote credential management
• Buildings without legacy phone-line infrastructure to leverage

When DoorKing is the right choice

• Budget retrofits where the existing analog phone-entry infrastructure is functional and the priority is hardware replacement at the lowest cost
• Smaller buildings without a property management system to integrate with
• Operators who specifically do not want a SaaS subscription
• Properties where residents are unlikely to install or maintain a smartphone app
