DoorVi is a smart doorbell app and QR video intercom system with visitor management and access control for homes, apartments, gated communities & offices. Answer the door from anywhere. A visitor scans a QR code at your door or gate. Your phone rings with a live video call. You see who it is, speak to them, and open the door — from the couch, the office or abroad. No visitor app. No wall handset. No cabling. HOW THE VIDEO INTERCOM WORKS 1. A DoorVi QR code is placed at your door, gate or building entrance. 2. The visitor scans it with any phone camera. 3. The right resident, apartment, employee or department is called on live video. 4. You see the visitor and open the door or gate from your phone. QR CODE VIDEO INTERCOM A video door phone without the wiring. Guests, deliveries, couriers, drivers, technicians and service staff reach you through one scan. • Live audio and video calls from a QR code • No app, signup or login for the visitor • Answer from anywhere with an internet connection • Speak to a visitor before deciding to let them in • A smart doorbell for one home, a video door phone for a whole building VISITOR MANAGEMENT DoorVi replaces the shouting at the gate, the phone calls and the paper register. Visitors reach the exact resident, apartment, office or department they came for, and the person being visited identifies them on video before anyone is let in. For a property, visitor management means one entry process across every door, gate and tower, without new cable to a single apartment. GUEST PRE-APPROVAL Expecting someone? Approve them before they arrive. Create a visitor pass with your guest's name and phone number, choose the access point they should use, and set the access details. Share the pass by WhatsApp, SMS or any messaging app. When your guest arrives, they enter with the access code they were given — no call, no waiting at the gate, no need for you to be reachable. Guest pre-approval is built for the visitors you already expect: family, house help and domestic staff, drivers, nannies, cleaners, deliveries, contractors and short-stay rental guests. ACCESS CONTROL AND GATE OPENING DoorVi connects the video call to the door itself. Open doors, gates, barriers, electric locks and relay-based entry systems straight from the call, and let pre-approved guests in with an access code. • Remote door and gate opening from your phone • Access codes for pre-approved visitors • Access control that works with a property's existing hardware • Keyless entry, with no fob or card to hand out DIGITAL CONCIERGE Place a Digital Concierge tablet at the entrance and visitors search for the resident or department they need, then start a video call from the screen. The same kiosk drives the gate, lock or relay, so arrival, verification and entry happen in one place. SMARTPHONE INTERCOM FOR BUILDINGS Residents, tenants, employees and security teams use the phones they already carry instead of a wall handset. A new apartment is added in seconds, not with a cable run. FOR RESIDENTS AND HOMEOWNERS • See and speak to every visitor before opening the door • Never miss a delivery because you were not home • Let family, staff or guests in remotely • Pre-approve guests and share access codes • Keep the door closed to anyone you do not recognize FOR PROPERTY MANAGERS AND DEVELOPERS • Video intercom across an entire property, without cabling • Faster, calmer visitor entry at the gate • Digital visitor management and guest pre-approval • Access control and Digital Concierge deployments • One system for residential, commercial and mixed-use property WHERE DOORVI IS USED DoorVi is used in apartments and condos, gated communities, villas, condominiums, offices and corporate campuses, co-working spaces, hotels and commercial buildings. QR code video calling, visitor management, guest pre-approval and access control, together in one intercom app. Questions, or planning a property-wide rollout? Visit doorvi.co
