Access Control Systems
The term access control refers to the practice of restricting entrance to a property, a building, or a room to unauthorized persons. Physical access control can be achieved by a authorized person, through mechanical means such as locks and keys, or through electronic access control means such as proximity cards, key fobs, biometric scans or keypad. These options whether mechanical or electronic are used to provide access. Controlling that access may provide safety and security to a private area. Access control systems become very useful in commercial & institutional applications when key management is required. A person may be granted access to a certain door at a particular time of day, an employee may be denied access to various departments by implementing a versatile security door access control system. A contractor may be denied access after work hours in your private home. Basically an access control system determines who is allowed access, when they allowed to access and where or what door they are allowed to access.
