Access control is a crucial component of physical security. It is an electronic system that controls the entry or exit of an area. With access control, only authorized personnel are granted entry to restricted areas, which can include a company's main entrance, server rooms, storage areas, and other sensitive locations.


Access control systems can be tailored to suit different needs. For example, biometric scanners, key fobs, and PIN codes can all be used to grant access. These systems can also be programmed to limit access during certain hours or days, depending on the organization's needs.

In addition to doors, access control systems can be used to control access to other areas, including buildings, floors, gates, cabinets, cash drawers, lockers, and more. By restricting access to these areas, organizations can prevent unauthorized access to valuable assets and safeguard sensitive information.

Access control is also not a one-size-fits-all solution. Different access levels and schedules can be assigned to each individual. For instance, you could give the accounting department access to the 6th floor only and give the maintenance department access to every floor.
