ACS (Access Control System) decides who gets where, when and under what conditions. The main value of the system is the combination kontroly (prevention of entry) a audit trails (pass logs).
Typical building blocks
- Controller (control unit): Evaluates access rules and controls the door/gate.
- Readers: RFID, PIN keyboard, biometrics (according to risk and GDPR).
- Identifier (credential): Card, chip, mobile phone (NFC), or QR.
- Element on the door: Electric lock, electromagnet, turnstile, barrier.
- Software: Manage users, schedules, permissions and events.
What people often underestimate
The weakest place is usually operational discipline: sharing cards, "holding the door", forgotten deactivation of accesses after cooperation ends. Therefore, it makes sense to combine ACS with CCTV a reportingem.
