Components That Make Up Access Control Systems

Access control systems are typically composed of multiple key components that work in concert to effectively control access:

1. Control Panel Access: This central control panel manages the whole system. The access control panel stores permissions for users, records activity, and communicates with the other components of the system.
2. Devices for Authentication: These devices verify that the person requesting access is who they claim to be. Standard authentication methods include:
   1. Proximity and Keycards: The card is presented to the card reader to gain entry.
   2. Keypads: The user enters a passcode or PIN.
   3. Scanners with biometrics: This device uses unique physical characteristics, such as fingerprints or retinal scans, to verify the user's identity.
   4. Mobile Applications: Certain modern systems use smartphones to authenticate users, which allows them access through a mobile application.
3. Locking mechanisms: The access control system uses electronic locks and door strikes to control physical access. They can be electromagnetic or electromechanical and are usually controlled remotely.
4. Access Database The database contains information on authorized users and their permissions to access the system. It also stores any credentials that are associated with them. This is an essential component in verifying the identity of users.
5. Readers and communication devices: The devices that communicate with authentication devices and the access control panel. These devices transmit data and check user credentials.
6. Monitoring: Access Control Systems maintain logs for all events. The audit trail shows who entered a room, at what time, and whether or not their access was allowed.
7. Access control software: specialized software manages users, permissions to access, and system configuration. Administrators can set up access rules and review logs to make necessary changes.
8. Notification and Alarm Systems: Certain access control systems integrate alarm systems that trigger alerts when there is an unauthorized attempt to gain access or a security breach.

How Do Access Control Systems Work

 

These systems regulate and manage access to digital and physical spaces. They ensure that only individuals and entities with the proper authorization can use or enter specific resources.

To control access, these systems use a combination of authentication, license, and monitoring. This is an overview of access control systems:

1. Verification: Verification is the process of verifying an individual or organization requesting access. Typically, this is done by using one or more methods.
2. Card-Based Authentication: The user presents an access card (e.g., magnetic stripe cards, proximity cards, smart cards, etc.) to a reader. Data on the card is compared with a database of approved users.
3. Keypad authentication: The user enters a passcode or Personal Identification Number into the keypad. To confirm your identity, the code entered is compared with stored data.
4. Authentication by Biometric Data: The biometric data (such as fingerprints or retinal scans) is captured, compared with pre-enrolled templates, and then used to authenticate the user.
5. Mobile authentication: Some systems today use mobile applications that receive or generate one-time codes to authenticate. Smartphones can be used for authentication based on proximity.
6. Authorization authorization determines which actions an individual authenticated can perform or what areas they are allowed access to. In this step, the database is used to check the access rights of each user. Access control systems use this information to determine whether or not to allow users to enter.
7. Access Denial or Grant: The system determines if access is granted after authentication and authorization. The system unlocks the digital gate or door if the user's credentials match those stored and the access rights are permissible. Access is denied if any step of the authorization or authentication process is unsuccessful. Access control systems can provide an audit trail of all accesses. This is useful for investigations and security audits.
8. Remote management and integration: Modern access control systems are compatible with many other building and security systems, such as alarms, video surveillance, and visitor management. The integration of these systems allows for an integrated security solution.

Some systems also offer remote administration capabilities. This allows administrators to monitor and control access anywhere they have Internet access.

It is beneficial in organizations with multiple offices or responding to requests for access outside regular business hours.
