Access Control

An access control system is used to restrict access to buildings or rooms to those with acceptable identification. 

The means of identification can include items that are carried such as cards and tags or characteristics of the individual such as retinal or fingerprint patterns, known as biometrics.  These identifying items are “read” by a reader and if the individual has the correct permissions, entry is granted by releasing the locking mechanism.  The entry of the individual through the entrance is usually recorded on a database.

The design of an access control system usually focuses on four areas.  These are 1) selection of the identifying token or characteristic, 2) selection of the door locking mechanism and 3) selection of the door controllers and finally 4) the access control system software which will run on a remote server and monitor the system.


Access Control systems are usually IP based, though most means of communication can be utilised, as the communications method is usually transparent to the system.

Access Control systems vary in their capability and price, with multi-site and multi-country capabilities being one differentiating criteria.

It is particularly important with access control to ensure that one is not locked in to a proprietary system.
