What is an access control system?

by | Nov 11, 2013 | Security Systems and Services

An access control system is a mechanism which selectively allows or denies access to places, buildings and other secure areas. Once installed, they can be configured to permit or deny access based on pre-determined criteria. This set of criteria can be updated at any time and the necessary individuals informed of the change. There are several types of access control available and anyone looking to invest in one should seek advice regarding access control system in Southampton.

Fingerprint Readers

Some access control systems incorporate fingerprint readers that allow or deny access based on individual’s security level. They are usually installed on a door and consist of a small plate on which the person has to place their finger or thumb. The door lock is then either opened if the person passes the scan or remains locked if they don’t. Fingerprint access control systems are very secure and extremely difficult to fool. They require some configuration as individuals join and leave an organisation but they are still a better option than issuing keys. They do not require a person to be physically stationed at the door or gate and so labour costs are saved in this respect. Fingerprint readers are just one example of biometric access control systems.

Eye Scanners

They may seem like something out of the movies but eye scanning access control systems are becoming more regularly used today. Like fingerprint readers, they are scanners that rely on biometrics to allow access. An individual requiring access will offer their eye to the scanner which is usually wall-mounted. If the scan of their eye matches a stored value in the system’s database then access is granted accordingly. If there is no match then the door remains locked regardless of how many scan attempts are made.

Combination Locks

Door locks sometimes consist of an alpha-numeric keypad that requires the correct code to be entered before access is granted. Individuals who should be allowed access are given the code so that they can enter accordingly. These types of access control are not as secure as the biometric types outlined above. This is because the access code can be given out to anyone either by accident or maliciously. It may end up becoming common knowledge and ultimately have to be changed as a result. Many companies have expert knowledge on Access Control in Southampton and individuals should seek advice before making a purchase. Visit Website for more details.
