What KNOC is
KNOC turns a printed QR code into a doorbell. A visitor scans it, sends a short message — text, voice note, photo, or phone number — and the owner gets a notification. The owner can reply from anywhere. No real-time call, no app required for the visitor, no public profile.
Why we built it
Traditional video doorbells trade away a lot of privacy in exchange for convenience: always-on cameras, faces uploaded to the cloud, third-party platforms that decide what to do with the footage. We wanted a calmer answer — something that lets a visitor knock and a homeowner respond when they choose to, without recording the whole street.
How it works
- Print a small KNOC QR code and put it where visitors can find it (front door, gate, reception desk).
- When someone scans it, they reach a simple page that lets them leave a message. No app install, no account.
- You get a push notification on your phone. Reply with text or a quick voice message; the visitor sees your reply at a unique link.
What guides us
Privacy first: collect only what's needed and delete it as soon as it's no longer useful. Local-feeling experience: ship in the languages and currencies where our customers actually live. Resilient over flashy: a doorbell only earns trust by working reliably, not by being clever.
