Access control is a security solution that manages and restricts entry to a building or specific areas within it. By utilizing advanced systems like PIN codes, biometric scans, or proximity devices, businesses can ensure that only authorized personnel gain access to sensitive areas. This level of control not only enhances safety by preventing unauthorized entry but also allows for detailed monitoring and auditing of who enters and exits the premises. With access control, businesses can improve security, reduce the risk of theft or data breaches, and have the flexibility to manage access levels for different employees or visitors.
