An Introduction To Access Control Systems In Pretoria
Refusing or granting access to a person due to certain conditions is part of our everyday lives. To unlock your front door you need a key, you need a bank card and a PIN to gain access to the money in your bank account at the ATM, and you need an access card or your fingerprint to enter your place of work.
Access control systems enable an authority to control access to areas and resources in a given physical facility or computer-based information system. Access control systems, within the field of physical security, are generally seen as the second layer in the security of physical structure.
These measurements are not only a security measure, but also a way to keep track of people entering or exiting a building for example. Access control systems in Pretoria generally makes use of three types of authenticating information:
- Something the user knows, e.g. a password, pass-phrase or PIN
- Something the user has, such as a smart card
- Something the user is, such as a fingerprint, verified by biometric measurement
Access control decisions are made by comparing the credential to an access control list. This lookup can be done by a host or server, by an access control panel, or by a reader. The development of access control systems has seen a steady push of the lookup out from a central host to the edge of the system, or the reader.
Today’s access control systems often incorporate special ID badges featuring smart card or proximity card technology. When the cards are waved in front of an electronic reader, access is granted. With card-based access control systems in place, it’s much easier to prevent intruders from roaming freely throughout the premises. This allows you to know exactly who is in the building at all times, which is the primary goal of most access control systems.
