Access control systems are designed to control and monitor access points such as doors, turnstiles,and car park barriers. A software package for the Microsoft Windows environment allows you to decide who goes where in your building and at what times, so that only authorised personnel may enter. A selection of the most popular systems are detailed below:
Keypad Code / Pin Access Control A keypad-based solution is a very cost effective way of preventing unauthorised access. Multiple-keypad systems can allow the movement of people through a property to be managed very successfully. They can be set up so that they are networked together so that setting-up access is simple and can be done from one location. If this is not required each keypad can be programmed individually, which can reduce the expense of the system.
Swipe Card Access Control Swipe Card-based systems allow users to access a property by swiping a uniquely-coded access card through a reader. This allows security personnel to program different sets of access criteria for each access point. The swipe cards are credit card sized and are very inexpensive, which makes them very suitable for premises with large numbers of users.
Proximity Access Control Proximity-based access control establishes the identity of users in much the same way as a swipe card system. The difference is that they are not required to insert or swipe a card to gain access. The user simply holds their proximity token or card within a given distance of a proximity reader and the system reads the data within it. Proximity system are very user friendly. The token is designed so that it can be carried everywhere so that the user does not forget it, and lost cards can be cancelled in seconds.
Biometric Access Control This technology establishes the identity of users by analysing certain biological characteristics of the individual to create a unique identifier. This is electronically stored and retrieved for later identification. Biometric systems are a very secure way of protecting a property because the user is the key. Theft or loss is not an issue with this type of system.
Audio / Video Intercom Access Control Intercom systems are a useful addition to any access control system, because they allow visitors to gain access to the property if a member of staff within the organisation permits them to. This is a necessary addition for organisations that receive visitors
