What is access control?

A good access control system helps your organization maintain a secure environment by allowing you to proactively control who can access your site and enabling you to monitor where, when, and why people are there at all times.

How do access control systems work?

An access control system consists of two main components: hardware and software. Hardware includes the physical components such as access cards, controllers, and readers. Software enables you to assign credentials allowing people to have the correct access to specified areas.

When someone waves their access card or mobile credential over the reader, it sends a message to a controller, which then authenticates the credential to verify that the user is authorized to enter. If they are, the controller sends a signal to the door lock instructing it to open.
