PC-Based Access Control
Organizations of all sizes are realizing the benefits of replacing
their old key- based systems for controlling access to buildings with
electronic access control systems. Besides for lower operating costs, a
PC-based system benefits you with ease of administration. A good example
is when keys are lost, locks would need to be replaced to maintain
security. On the other hand, a card-based access control system allows
lost cards simply to be cancelled.
Card access control systems also increase security levels, by controlling
which parts of a building can be accessed, and by whom. A PC-based,
networked access control system, will maintain control from a central
location and provide reports on the movements of employees and visitors
throughout the building.
