Access control is a system that enables an authority to control access to areas and resources in a given physical facility, or computer-based information system. Within the field of physical security, it is generally seen as the second layer in the security of a physical structure.
Access control systems let authorized employees get in and out of various parts of your business while keeping other people out. They can range from simple electronic keypads that secure a single door, to large networked security systems for multiple buildings that can include parking lot gates, integration with time and attendance systems, and multiple levels of security.
There are several components that make up an access control system including:
- Control Panels
- Card Readers
- Fingerprint Readers
- Door Strikes
- Magnetic Locks
- Request to Exit Devices
