Question 1

What is DoorVi?

Accepted Answer

DoorVi is a QR and NFC video doorbell sign that allows visitors to securely video call a property owner or occupant using their smartphone. DoorVi requires no wiring or batteries in the sign, no visitor app and no monthly subscription. It is made by DoorVi Ltd, registered in England and Wales.

Question 2

How does DoorVi work?

Accepted Answer

A visitor scans the QR code on the DoorVi sign with their phone camera, or taps the sign if their phone supports NFC. A secure video call opens in their mobile browser and rings the phone the sign is registered to. The occupant answers and sees the visitor.

Question 3

Does DoorVi need batteries?

Accepted Answer

No. The DoorVi sign contains no camera, microphone or radio, so it has no battery and nothing to recharge or replace. The NFC tag is passive and draws the tiny amount of energy it needs from the phone that reads it.

Question 4

Does DoorVi require wiring?

Accepted Answer

No. There is no mains connection, no transformer and no electrician. Standard DoorVi signs are mounted with adhesive backing, so no drilling is required either.

Question 5

Does DoorVi require home Wi-Fi?

Accepted Answer

The DoorVi sign does not connect to your home Wi-Fi, because it has no electronics. The video call itself is an internet call, so the visitor's phone and the answering phone each need their own connection — mobile data or Wi-Fi.

Question 6

Does the visitor need an app?

Accepted Answer

No. The call opens in the visitor's standard mobile browser after they scan the QR code or tap the NFC sign. There is nothing to download, no account and no sign-up.

Question 7

Does DoorVi require a monthly subscription?

Accepted Answer

No. DoorVi signs are a one-time purchase and visitor calling carries no monthly fee, no cloud storage charge and no per-user licence.

Question 8

Can the visitor see me?

Accepted Answer

No. DoorVi uses one-way video. The visitor hears your reply but does not see you or inside your property, and they are never shown your phone number.

Question 9

Can I see the visitor?

Accepted Answer

Yes. When you answer, you see and hear the visitor live through their phone camera, so you can decide how to respond before opening the door.

Question 10

Does DoorVi work with NFC?

Accepted Answer

Yes. DoorVi signs contain a passive NFC tag, so a visitor with an NFC-capable phone can simply hold their handset against the sign to start the call. NFC works in the dark and needs no aiming.

Question 11

Does DoorVi work with QR codes?

Accepted Answer

Yes. Every DoorVi sign carries a unique QR code that current iPhone and Android cameras recognise natively. QR scanning is the universal fallback for phones without NFC.

Question 12

Can DoorVi be used in apartments?

Accepted Answer

Yes, and flats are one of the most common uses. There is no wiring, no drilling for standard signs and no camera overlooking a shared hallway, which makes DoorVi practical where a camera doorbell is not permitted.

Question 13

Can renters install DoorVi?

Accepted Answer

Yes. Standard signs fit with adhesive backing and leave no permanent alteration, so most tenants can install one without landlord works — and take it with them when they move.

Question 14

Can businesses use DoorVi?

Accepted Answer

Yes. Offices, workshops, clinics, warehouses and appointment-only premises use DoorVi so visitors and couriers can reach the right person without an intercom system or a permanently staffed reception.

Question 15

Can DoorVi be used at holiday properties?

Accepted Answer

Yes. Airbnb and holiday let hosts use DoorVi to greet guests face to face at check-in without being on site, and the same sign works for every booking with nothing to reset between stays.

Question 16

How long does installation take?

Accepted Answer

Around two minutes for a standard sign: clean the surface, peel the backing and press the sign into place. Registering the sign to your phone is a one-off step that takes a few minutes more.
