What access control does
An access control system decides who can open which doors (or gates), when, and leaves an audit trail of attempts. Typical credentials include proximity fobs/cards, PIN pads, mobile credentials and, in higher-security areas, biometrics. Controllers, readers, locks and software work together — replacing a lock alone is rarely enough for multi-door commercial sites.
Many buildings combine access control with door entry / intercoms for visitors and with CCTV at main entrances for visual verification.
Common credential options
Fobs & cards
Widely used, low training burden and easy to issue or revoke. Choose encrypted formats where practical and keep a clear leaver process so credentials cannot outlive employment.
PIN & mobile
PINs suit low-traffic internal doors but can be shared. Mobile credentials reduce plastic fobs; plan for lost phones and offline doors if the network drops.
Biometrics
Useful for higher-security zones. Consider hygiene, enrolment time, false rejects and data protection duties before rolling out site-wide.
Visitor workflows
Temporary cards, receptionist release or video door entry keep contractors and guests out of permanent user lists while maintaining a record of entry.
Fire safety and fail-safe design
Controlled doors on escape routes must still allow people to leave safely in an emergency. Maglocks, electric strikes and release mechanisms need correct power-fail behaviour, break-glass or green-box overrides where required, and integration with the fire alarm where the fire risk assessment specifies free exit or automatic release. Never “secure” a door in a way that traps occupants — coordinate security goals with your fire strategy and competent installers.
What a typical project includes
- Site survey — door schedule, traffic patterns, network/power, fail-safe requirements.
- Hardware selection — readers, locks, door contacts, request-to-exit devices, controllers.
- Software set-up — time zones, access levels, anti-passback where used, admin users.
- Commissioning & training — test every door, hand over manuals, issue first credentials.
- Ongoing admin — add/remove users, report on events, schedule maintenance.
Brands such as Paxton are common on UK commercial stock; we also support multi-door networked systems for larger portfolios.
Day-to-day management tips
- ✓ Disable leavers the same day — do not wait for a monthly tidy-up.
- ✓ Use named credentials, not shared “contractor” fobs that never expire.
- ✓ Review event logs after incidents; keep admin passwords under dual control.
- ✓ Book periodic service for door closers, locks, batteries and controller health.
- ✓ After office moves or new tenancies, re-map access levels rather than cloning old rules blindly.
