A door entry system with nothing behind the wall
The QR code placard is wired to the door release you already have. Everything else — the calling, the video, the unlock — happens on phones that are already in people’s pockets.
A QR code placard at the door
A small plate beside the entrance, fixed at eye height and wired into the existing release. No handsets in any flat, no risers, no trunking, nothing pulled through the building.
The visitor points a camera
The call opens straight in their browser, so there is nothing to download and nothing to sign into. Calls only connect when the visitor is actually at the building.
The resident answers, wherever they are
Live video and audio, and a one-tap door release — from the sofa, from work, or from another country. Every call is logged with a photo of whoever was at the door.
Visitors point their camera at the QR code placard and the call opens in the browser.
A snapshot is captured on every call, answered or missed, and kept in the building log.
The door only rings when the visitor is at the building, not from across town.
On holiday, at work, or upstairs — the door rings the phone wherever it is.
Quote from the first installation goes here — one or two sentences from the resident or the engineer who fitted it.
