Which component connects door readers, door locks, and the access control server?

The control panel serves as the crucial component that connects door readers, door locks, and the access control server in a security system setup. Its primary function is to act as an intermediary, facilitating communication between the various hardware elements involved in the access control process.

When a user presents their credentials (like a keycard or a biometric scan) to the door reader, the control panel interprets this data and determines whether access should be granted or denied based on the rules set in the access control server. After processing the information, the control panel sends commands to the door locks, either allowing them to unlock if access is granted or keeping them secured if access is denied.

This central role is vital for ensuring that all components of the access control system work seamlessly together, maintaining the integrity and security of the environment being protected. Other components mentioned may have their own important functions, but they do not perform the essential role of connecting and allowing communication between the door readers, locks, and server effectively.
