Case file
AI face-recognition for access, attendance and surveillance — face-based entry, watchlist and VIP/denied-entry alerts — integrated with CCTV and access control on a consent-aware, privacy-respecting deployment.
| Aspect | Off-the-shelf | Engineered approach |
|---|---|---|
| Accuracy | One threshold out of the box | Enrolment and accept/reject tuned to the door's real lighting, angle and throughput |
| Security | Face alone | Face paired with card or PIN on higher-security doors; every match logged for audit |
| Privacy | Vendor defaults | Consent-based enrolment, client-controlled templates, scoped watchlists and written retention rules |

/ The discipline, in detail
How we approach facial recognition system.
Face recognition only earns its place when it is accurate, fast and accountable. We design enrolment and matching against the real lighting, angle and throughput at the door rather than ideal lab conditions, so a genuine person is recognised quickly and a stranger is not waved through. Faces can release a door, mark attendance or flag a watchlist hit, and every match — accept, reject, alert — is logged for audit so the system can be reviewed after the fact rather than trusted blindly.
We treat face data as sensitive from the first design conversation. Enrolment is on a consent basis with a clear notice, templates are kept on the system the client controls, and VIP, staff and denied-entry watchlists are scoped to who genuinely needs them. The recognition layer is integrated with the existing CCTV and access-control systems so a match can open a barrier, raise an alert at the security desk or simply tag a recording — coordinated, commissioned and documented, with the matching thresholds and retention rules written into the project file rather than left to a default.
On record
Every facial recognition system engagement is documented end-to-end — design, programming, commissioning, calibration — and handed over with the files our successors would need if we were never to return.

/ Frequently asked
Facial Recognition System — what buyers ask first.
Is facial recognition reliable enough to control a door?
It is when the matching threshold is set for the door it guards. We tune enrolment and the accept/reject threshold to the actual lighting, angle and throughput, and pair face with a card or PIN on higher-security doors so a poor read never becomes a free entry — every match is logged for review.
How is privacy handled with face data?
Face data is treated as sensitive from the first design conversation. Enrolment is on a consent basis with a clear notice, face templates are stored on the system the client controls, watchlists are scoped to who genuinely needs them, and retention rules are written into the project file rather than left to a default.
