Unmanned Store Face Access

Face recognition opens a door for enrolled people and turns away photos and phone screens. It keeps working from the last loaded face list if the cloud drops, and logs every decision in a tamper-evident record. It suits staff entrances, night self-service shops, co-working floors and equipment rooms.

0.66 s: median face to unlock signal on reCamera Pro, 1,000-person library (replayed test clip, excludes lock travel)
0/40: unregistered people let in (replayed test)
0/60: phone or screen replays let in (replayed test)
about 30 s: time for a roster change to reach devices

Results reported by the design's authors on their own test setups. Yours depend on the site, so we confirm them in a pilot.

The problem

Why it matters.

Unstaffed doors need face entry that cannot be fooled by photos, keeps working offline and logs every unlock.

The flow

From signal to action.

01SenseDoor cameraA reCamera at the door, or an existing IP camera, sees a face at the threshold.
02DecideMatch and livenessThe face is checked against the local library and tested for spoofing.
03ActRelay pulseOn a match, a relay closes a dry contact into the existing door controller.
04RecordEvent logEvery allow or deny is published over MQTT and written to an append-only audit log.
05PeopleAdmin consoleAdmins enrol or remove people, and devices pull the signed new list within about 30 s.

How it works

Step by step.

01Choose a route: reCamera Pro at the door, a PoE reCamera with an MQTT relay, or an IP camera with a reComputer host.
02Wire a relay rated for the lock into the door controller, with the lock on its own 12 or 24 V supply.
03Set up the library service, console and broker on a Docker host.
04Enrol each person with 3 to 8 face images.
05Set pulse length, relay type and fail mode, then calibrate thresholds on the installed camera.
06Review the audit log for every unlock and refusal.

Before you install

A separate 12 or 24 V lock supply and a relay rated for the lock's 300 mA to 1 A draw.
A camera at about face height where people stop at the door.
Lighting that avoids backlight from glass doors or windows behind the person.
A Linux Docker host (amd64 or arm64) for the library, console and broker.
Network to the door, or PoE for the reCamera 2002 HQ.

Good to know

Not certified for fire exits or doors under building codes; keep a mechanical override.
The reference face model is for non-commercial research and must be replaced for commercial use.
On MQTT relay routes the door only opens while the broker is up.
Face data is sensitive personal data, so enrolment needs consent and a deletion process.

How we deliver it

Paper to site, one team.

01Site surveyWe walk the site, or review photos and drawings, and agree what to measure and where each device goes.
02PilotOne lane, one line or one room first. We tune it on your conditions and agree what good looks like.
03Roll outWe supply the hardware in India with GST invoices, install it, and connect it to the systems you already run.
04SupportSpares, remote checks and model updates, with one team to call when something changes.

Questions

Asked before buying.

Will the door open if the internet goes down?

Yes on reCamera Pro, using the last face list it loaded. Routes that unlock through an MQTT relay need the broker.

Can someone use a photo on a phone?

Liveness checks rejected all 60 screen replays in testing, but thresholds must be calibrated on your installed camera.

Can we use it on a main fire exit?

No. It is not certified for safety-critical or code-governed doors.
