Introduction to Access Control Systems

Access control is a security technique used to selectively grant or restrict access to specific people for particular areas.


Gaining access to any area or task requires proper authorisation from responsible persons.


Access control is a modern and dependable way to provide or restrict access to your premise while ensuring high degrees of security.


This can potentially reduce manning costs and paperwork.


Access control could be as simple as issuing or taking away a key, which is a time-consuming and manual process.


This in itself can be a risk if someone were to lose their key, meaning you would have to rekey the locks.


This can be an expensive exercise, particularly if you have a large organisation with many people holding many keys.  


The more efficient way is to use an electronic access control system. This is where the credentials are used, such as an access card, fob, or biometrics.


These are electronically programmed to give access to the required areas of the user.


The beauty of these systems is that if access needs to be changed, or the credential is lost, it can be quickly reprogrammed.


What Are Access Control Systems Used For?


Access control systems are extremely useful in a variety of commercial situations.


This can range from large organisations and institutions to smaller businesses and buildings.


These systems control what areas people have access to, as well as to record the areas the user has accessed and when they did so.


This information makes monitoring the whereabouts of employees or visitors extremely easy and helps in the efficient monitoring of security.


What Are The Different Types Of Access Control Systems?


1. Electronic Key System - These systems operate similarly to the traditional key, where you physically need to use the electronic key to operate the lock.


The difference with an electronic key system is, as the name suggests, the key is electronic and it has a battery inside the key.


This key can be programmed to access doors as required, and even can be programmed to access doors within specified time constraints.


Electronic key systems are probably the easiest of all access control system to install.


As in most commercial applications, it is only the cylinders on the door locks that need to be replaced, which is a very easy process.


The cylinder itself is powered from the battery in the key when the key is inserted.


This is what makes this type of access control system quick to install, as no power or battery needs to be installed on each door.


Keys can even be programmed so that their access expires on a regular basis, and need to be verified by a programming device.


Electronic key systems offer the same functionality as other access control systems, allowing keys to be programmed or deleted if they are lost.


2. Wireless Access Control - these access control systems are the next step up from electronic key systems.


They use credentials such as an access card or fob and offer greater functionality.


These types of systems have batteries on board, with the batteries lasting up to 24 months, depending on use.


Some of the functions include remotely programming and controlling doors, as well as the time zone functions as electronic key systems.


This means users are only able to access doors on certain days or between particular times.


Wireless access control systems are involved to instal, particularly when retrofitting an existing building.


In this case, the entire lock has to be replaced with a wireless access control lock.


These systems are popular in larger institutions, such as schools and colleges.


One of the best functions is the ability to immediately lock all locks throughout the campus during an emergency.


3. Wired Access Control - these systems have all the functionality of wireless access control systems.


However, these are the most involved access control systems to install, as each door requires a cable to be run from a central location.


The advantage of this is that once the system is installed, there is little maintenance is required.


Most notably, there are no batteries that need to be replaced on a regular basis.


Wired access control systems also give more options on what credentials can be used.


This ranges from access cards, fobs, and even biometrics, including fingerprint scans and facial recognition.
