In situ
A visual tour of how entriv.io lives inside the door. The guest taps a phone — primarily over NFC, optical scan only when NFC isn't possible. The same tap opens the building's gate and your apartment door. Designed in Cannes; deployed wherever your guests arrive.
Inside the door
entriv.io attaches to the interior face of the front door, at peephole height. The peephole is the only window onto the landing; nothing on the outside is added, drilled, or modified. From the street, the door is unchanged.
The wood of the door itself is part of the design — the NFC antenna inside it couples to a phone held against the outside, reading the guest's credential through 40 mm of oak. No external panel, no visible reader.
Cross-section
A horizontal slice through the door at peephole height shows the camera using the original optic, the NFC field crossing the wood to meet the guest's phone, and the privacy boundary that lives entirely in software.
In context
We pilot on the Riviera because we live here. The same Porter, the same backend, the same install pattern works in any country where Airbnb or Booking.com take a reservation.
Boulevard de la Croisette
Penthouse
Building entrance + apartment door
The Porter sits inside the apartment door at the peephole; a separate Porter Bridge inside the flat opens the building's porte cochère via a relay across the Comelit handset. One credential, both doors — and nothing visible from the boulevard.
Cap d'Antibes
Villa
Standalone smart deadbolt
A Yale Linus L2 retrofitted to the original brass cylinder. The Porter inside the door reads the guest's phone NFC through the wood, then commands the lock over Matter. The front face of the villa is untouched — important for a listed property.
Vieux Port, Saint-Tropez
Townhouse
IP intercom (DoorBird)
Where a modern IP intercom is already in place, entriv.io speaks directly to its HTTP API — no extra wiring, no relay. The Porter behind the apartment-door peephole authenticates the guest, then instructs the intercom to release.
Èze village
Cliffside
Offline-first, LTE failover
Old stone, ancient WiFi. entriv.io caches the next 14 days of grants locally and falls over to a 4G modem when the line drops, so a guest arriving at midnight is never left at the gate.

Worldwide
Same Porter, same install
The Porter is geography-agnostic. We've designed for thick oak Haussmann doors, but it works on any wooden, hollow-core or composite door — and a doorframe-trim antenna option covers steel security doors. Booking channels are pulled by iCal, which every major platform exposes worldwide.
From the foyer
The Porter shares its eye-level position with the door's peephole, consoles and mirror remain exactly as the owner left them. Most guests don't notice it until they need to.
For owners who prefer it to be even less visible, a brushed-bronze finish lets the device read as a slightly elaborate peephole backing-plate rather than a piece of technology.
Apartment block
For older blocks, a compact Porter Bridge sits inside the apartment beside the existing handset. An opto-isolated relay wired in parallel with the "open door" button means the same credential that opens your apartment door also opens the street entrance — without touching the building's wiring or the residents' handsets.
Compatible with most Comelit, Aiphone, Urmet, BPT, Fermax and similar systems. For modern IP intercoms (2N, Akuvox, DoorBird) we speak to their HTTP API directly — no relay needed.
The appliance, in detail
« We chose entriv.io because the answer to 'where do we put the camera?' was: you don't. »— Property owner (composite, pilot programme)
