Access control is a security measure that regulates who can enter specific areas at any given time. Advanced access control systems ensure that only authorised users are permitted entry, verifying the identity of individuals as they enter or exit monitored spaces.
These systems employ various methods for controlling access, including Radio Frequency Identification (RFID) locks, biometric scanners, electromagnetic locks, keycards, and smartphone applications.

When an individual attempts to access a restricted area, their credentials are authenticated. This could involve anything from a fingerprint scan to a security card read, which is then sent via the Access Control software. This software program determines whether the user should be granted access.

The Access Control software checks if the user has permission to enter the specific area by conducting a series of digital validations, including:

– Ensuring the correct type of credential is used for that area
– Verifying that access is attempted within an authorised timeframe
– Confirming the use of an appropriate trigger type

If the user successfully meets all these criteria’s, access is granted, and the security device is unlocked. The unlocking mechanism varies depending on the type of device in use. For instance, with an electromagnetic lock, the power supply is temporarily interrupted to release the lock, while for door strikes, the power is activated to unlock the door for a few seconds.

In the case of wireless locks, the latch engages only when an approved credential is presented, remaining disengaged at all other times. This setup allows for free exit from the area while preventing unauthorised entry.
