Access control systems are systems that are used to manage and restrict access to buildings, rooms, or secured areas. They can consist of mechanical or electronic locks, card readers, fingerprint readers, or other technologies.

Access control systems can be used to restrict access to buildings, offices, data centers, parking garages, apartment buildings, and other secured areas to only authorized individuals. They can also be used to record who has access to certain spaces and when, which can help with compliance with laws and regulations, reducing theft, and improving overall security.

There are many different types of access control systems available, depending on the needs of the building or space and the amount of security that is required. Some examples of access control systems are electronic locks, card readers, fingerprint readers, biometric scanners, and security cameras.
