From fingerprint readers to ANPR barriers — what access control actually does, and how to choose the right level for your site.
Control who goes where, and prove it\n\nAccess control is the difference between a site you can audit and a site you can only hope about. Every system on this page does the same core job: it decides who enters, when, and records every attempt.\n\n### The levels\n\n- Card and PIN — cheapest per door, fine for staff-only areas and back offices.\n- Biometric — fingerprint or face readers for doors where you cannot afford a shared credential (server rooms, vaults, HR).\n- Mobile credentials — phones replace cards entirely; issuance and revocation happen in seconds from a dashboard.\n- Vehicle access — ANPR barriers and interlock for car parks and compound gates.\n\n### What to look for in an installation\n\n1. Lock hardware is 80% of the result. A flimsy electric lock undercuts the smartest reader. We spec electromagnetic or electric mortise locks to match the door and the risk.\n2. Fail-safe vs fail-secure. Do doors unlock on fire alarm (life safety) or stay locked (high security)? The decision is yours, and it is a design decision, not an afterthought.\n3. One system, one log. Card, biometric, and intercom events in a single timeline beats three disconnected systems when an incident is investigated.\n4. Revocation that actually works. Can you remove a leaving employee\u2019s credential in under a minute? If not, the system is a liability.\n\n## The takeaway\n\nStart with the doors that matter, get the locks right, and buy a system where revoking a credential is a ten-second job. Everything else is configuration.
