A door access control system can be generally classified based on its operational framework or the kind of credential it employs.

By Organizational Framework:

• Standalone Systems:
  • Oversee one door or several separate doors
  • The reader and controller are frequently integrated into a single unit.
  • Programming occurs directly on the device or through a USB connection.
  • There is no centralized management or real-time logging for multiple doors.
  • Ideal for:
    • Small offices
    • Single rooms
    • Storage areas
• Networked (On-Premise) Systems:
  • Multiple readers and controllers connect to a central server within the organization’s local network
  • Managed by dedicated software installed on a local computer
  • Offers centralized control, real-time monitoring, detailed audit trails, and integration capabilities
  • Ideal for: Medium to large businesses, multi-floor buildings, factories
• Cloud-Based Access Control Systems:
  • Credential data, permissions, and logs are stored and managed securely in the cloud
  • Administrators can manage the system remotely via a web browser or mobile app
  • Offers high scalability, automatic updates, easier integration with other cloud services (HR, visitor management), and reduced on-site IT maintenance
  • Ideal for: Companies that operate in various locations, employ remote teams, or are in search of a versatile and low-maintenance option

By Credential Technology:

1. Keycard/Fob Systems: Use physical cards or fobs (usually RFID) that are tapped or swiped
2. Keypad/PIN Systems: Require users to enter a numeric code on a keypad
3. Biometric Systems: Authenticate users based on unique physical characteristics (e.g., fingerprint, face, iris, palm vein).
4. Mobile Credential Systems: Allow smartphones to act as credentials via Bluetooth or NFC.

Benefits of a door access control system:

• Enhanced Security: Prevents unauthorized persons from accessing restricted zones, thereby safeguarding assets, information, and personnel
• Centralized Control: Allows administrators to manage all access points from a single platform, easily granting or revoking access rights
• Detailed Audit Trails: Provides comprehensive logs of who entered where and when, crucial for security investigations and compliance
• Eliminates Keys:

  Minimizes the security threats and expenses related to lost, stolen, or duplicated physical keys, as well as the necessity for rekeying.

• Flexible Access Levels: Allows different access permissions to be assigned based on roles, departments, or time schedules.
• Remote Management: Cloud-based systems enable administrators to manage access permissions instantly from any location with internet access
• Improved Efficiency: Streamlines entry/exit processes and can integrate with other systems like time attendance or visitor management
• Increased Safety: In emergencies, systems can be configured for instant lockdown or automatic unlocking (for emergency exits)
