Access Control Systems provide precision management of entry and exit, ensuring that only authorized personnel can access sensitive or restricted areas. Technologies include RFID card and fob readers, biometric authentication (fingerprint, facial, or iris recognition), mobile credentials, and PIN-based keypads. These systems integrate seamlessly with CCTV, fire alarm, and building management platforms, enabling a unified security environment. Key capabilities such as role-based permissions, real-time monitoring, time-stamped audit trails, and remote administration support compliance with international standards like ISO 27001 and local data-protection regulations, strengthening both physical and information security.
