Access Control Systems Ensure the Required Security for Areas Where Access Needs To Be Restricted
Access control to any space, property or area is required to impose a selective restriction on the personnel entering that particular place. This requires permissions to be obtained for access.
Ticket checker, bouncers and guards ensure geographical access control to any restricted area. This can be through the means of physical barriers like fences, gates, turnstiles while entry points to countries may also include the checking of valid documents at access control points. Access control refers to the restriction of entry to a space to allow only those authorized to enter. The simplest form of access control system is a door with a lock and key to permit entry. Keys are given to only those who are authorized to entry, like for a home, an office space, a commercial enterprise, or production facility. This is a mechanical form of access, which does require the possession and operation of keys.
The use of electronic devices has now gained an entry into the types of access control systems that are gaining wide use in almost all forms of security arrangements to required access, whether it is to a physical space, a computer or other device, safes and vaults. In most electronic access control systems, keypads require to be operated in a particular sequence to permit entry or opening of the door or other access. In most of these systems all such entries are recorded and the access is open for a limited time, after which it again closes. Unsuccessful attempts to access are also recorded as a matter of security.
There are other access control systems which require cards or credentials presented to the device, which then reads the information, verifies its authenticity and then permits access. The control panel on this device has a list of valid credentials, and this allows security personnel to even monitor or restrict access easily by modifying the list. As credentials can be exchanged, many access control systems require an additional factor or password to verify entry. These problems have been reduced with the introduction of access control systems that depend on biometrics to permit access. in these systems fingerprints, iris scans and face recognition are the various methods in use to authenticate the identity of the person needing the access to a restricted space.
Access control systems vary a great deal in their ease of use and the complexity of the systems they use to control access. Cost is a major factor for deciding on the systems that an establishment, home, office or business needs. The actual operations in any area may also decide on the need to control access. Where security of personnel and any proprietary items are not great importance, the simplest access control systems, which require gates and guards may ultimately turn out to be just as effective. Where there is need for a greater degree of system, identity cards can serve the purpose. Where intellectual properties are at risk, more sophisticated systems may get installed. The highest degree of security is necessary for defense establishments, and other vital installations. These can benefit from the latest biometric and other electronic access control systems.
