Simple Install
Minutes, Not Hours
Mount with adhesive tape or screws on virtually any surface — glass, brick, metal, stucco, stone, or wood. No wiring, no power, no internet connection needed at the door.
No App Required
For Visitors
Visitors scan the QR code and access a web-based intercom directly in their smartphone browser. Zero friction for guests, deliveries, and service providers.
How It Works

Visitors scan the QR code to launch a web-based intercom from their smartphone. No mobile app download required — instant access for guests.

Video Calling
Residents and staff can see who's at the door, gate, or garage before granting property access via one-way video with two-way audio.
Swipe-to-Open
Residents and staff use the ButterflyMX mobile app to swipe and open doors and gates — no key, fob, or card needed.
