🔐 What is Access Control?
Access control is the selective restriction of access to a place or resource, typically using electronic systems rather than traditional keys. These systems log entry/exit activity and can be customized to give different access levels to different users.
🧩 Core Components of an Access Control System
- Access Credentials
- Keycards / Fobs
- PIN Codes
- Biometric Data (fingerprint, face, retina)
- Mobile Credentials (smartphone-based)
- Access Control Readers
- Devices installed at entry points that scan or read the credentials.
- Control Panel / Server
- The brain of the system; validates credentials and grants or denies access.
- Electric Locking Hardware
- Magnetic locks, electric strikes, or smart locks that secure doors.
- Management Software
- Interface to configure permissions, monitor activity, and generate reports.
🏢 Common Applications
- Office buildings: Restrict employee access to certain floors or rooms.
- Apartments: Control lobby and unit door access.
- Schools: Secure classrooms and administrative areas.
- Data centers: Limit access to server rooms.
- Hospitals: Protect sensitive areas like medication storage or patient records.
✅ Benefits of Access Control
- Enhanced Security – Prevent unauthorized entry.
- Audit Trails – Keep logs of who accessed what, when.
- Remote Management – Control and monitor access from anywhere.
- Custom Permissions – Set access levels for different users or groups.
- No Need for Physical Keys – Reduce risks of lost or duplicated keys.
- Integration Friendly – Works with CCTV, alarms, and time-tracking systems.
💡 Example:
A company might allow employees to access the building between 8 AM and 6 PM using a keycard, but restrict access to the server room to IT staff only. If an employee tries to enter after hours or access a restricted area, the system can deny access and alert security.
