Access Control

Door access refers to a system or technology designed to control and manage who is allowed to enter a building, room, or other restricted areas. These systems are used to maintain security, ensure safety, and manage the flow of people within various environments, such as offices, schools, data centres, government buildings, hospitals, and residential complexes. 

Key components and concepts involved in door access systems include:

• Access Control Systems: A system that regulates entry by granting or denying access based on predefined rules. This can be integrated with other security systems, like CCTV and alarm systems.

• Authentication Methods: The techniques used to verify someone's identity before granting access. Common methods include:

  • Keycards or Key Fobs: Plastic cards or electronic devices with embedded chips that grant access when swiped or tapped on a card reader.

  • Keycodes/Pin Codes: A numeric or alphanumeric code that must be entered into a keypad.

  • Biometrics: Identification based on unique physiological features like fingerprints, facial recognition, or retinal scans.

  • Smartphone-Based Access: Mobile apps that use Bluetooth, NFC, or QR codes to unlock doors.

• Locking Mechanisms: Physical components that secure doors, such as electronic locks, magnetic locks, or traditional deadbolts that can be controlled electronically.

• Access Logs and Audits: Systems that keep track of who enters and exits, along with the time and other details. This data can be used for security audits, compliance, and investigations.

• Authorization Policies: Rules that define who has access to specific areas, at what times, and under what conditions.

• Remote Access Control: The ability to control door access from a distance, allowing security personnel to lock or unlock doors remotely.
