Access Control > System Overview
Aside from the problem of keys often getting lost and locks being expensive to replace, the major drawback of keys from a security perspective is that people who have the keys to a facility have unlimited access and their comings and goings cannot be tracked. An access control system, on the other hand, provides a building’s owner-operator with the ability to restrict access to his facilities to certain times of the week or day and to certain areas of the building.
There is no longer any need to issue keys to staff at all. Employees, contractors, delivery people, and so on, simply get an access card and/or a code that grants them access to the appropriate doors at the appropriate times of the day and makes movement traceable – who was where, when.
