Locking mechanisms are fundamental to access control because they prevent unauthorized individuals from entering a secure area. They serve as a physical barrier that helps to ensure that only those who have the right to access certain locations can do so. By controlling who has the keys or codes to these locking systems, organizations can effectively manage and limit access based on specific needs, enhancing overall security.

Surveillance cameras, while crucial for monitoring and recording activities, are more focused on observation than access control. Alarm systems alert personnel to breaches but do not physically stop intrusions. Monitoring personnel play an important role in overseeing security measures and ensuring protocols are followed, but they are not mechanisms that physically restrict access. Locking mechanisms stand out as the primary means of directly controlling access to secure areas.
