Access Control Systems: A Beginner's Guide

Access control decides who can enter which areas, when — and keeps a record. It's a cornerstone of physical security.

How it works

Credentials — cards, PINs, fingerprints or mobile keys — are checked against a controller that unlocks doors only for authorised people, logging every event.

What to consider

Decide on credential types, how many doors, whether you need multi-site management, and integrations with HR, time-and-attendance and CCTV. Plan for failsafe operation during power loss.

Getting started

Start with your highest-risk doors and scale out. Al-Gazelle supplies and installs access control with central management and audit trails.
