DoorVi is a QR-code video intercom and visitor management platform: visitors scan a QR code and video-call the resident from their own phone, and residents unlock gates and doors remotely through relays or access-control integrations. No entrance panel, no intercom wiring. DoorVi opens real doors and gates through low-cost relays (ESP32, Sonoff, Tasmota, Waveshare) or through the access control a building already has. DoorVi is an official ProdataKey (PDK) video intercom integration partner and also integrates with Brivo, Mobgate and Intelbras. Features: six-digit guest codes, visitor pre-approval and temporary passes, Guard/Doorman app, tablet-based digital concierge, resident-to-guard calling, building-wide announcements, visitor logs and a multi-property admin dashboard. Used by apartment buildings, gated communities and housing societies, offices, co-working spaces, hotels and homes in Brazil, India, the United States and the UAE.
