What is Access Control? In simple terms it is the system used to control access to your property or business.  The purpose is to grant entry only to those authorized to be there.  In years gone by the equivalent would have been the lock with the big brass key.  But today there are numerous options for access control systems.  Not only allowing us to grant access to authorized persons, but also to monitor and manage access.

 The big brass key made way for key cards, ID badges and fobs.  But even these have become outdated as advances are continually being made in the field of technology and subsequently Access Control.

Many people may think access control is merely made up of a card and a card reader mounted on the wall next to the door.  But there are many more options available, even the abilities to tie in seamlessly with your intruder alarm system. This article will take a closer look at the options available in the field of access control, both for home and business application.


Audio Intercom

The simplest system for home or business use is the intercom system.  This has a base unit mounted at the gate / door and a handset mounted inside the premises.  The base unit has a single button to press which buzzes inside.  The person picks up the handset and can enquire who is at the door and allow them access by pressing the release button on the handset.  In the case of apartments/ businesses the base unit will have more than one button, which will be assigned to the various apartments or businesses.

The next step  up on the audio intercom system, would be where the base unit has a keypad.  This allows access via a code to be entered, or as with the previous system, the visitor would press the button and be granted access by the resident.

Video Intercom

Here the base unit has a camera, and the handset unit has a 4 or 7 inch monitor.  This allows you to see who is at the door/gate before granting them access to your premises.

The more advanced video intercom systems link through to your cellular phone, allowing you to see who is at the gate and grant access from any location.

Wireless intercom

In this category you would find units like the Centurion GSpeak.  This has a base unit mounted at the gate and is programmed to your cell phone which acts as the handset.  This allows you to answer your intercom from anywhere in the world.  

You can also remotely monitor any activity on your GSpeak, or open your gate from any location via a missed call, SMS or your phones keypad.   There are also some advanced features that come with this particular model.  It sends notification if the gate is left open, the power has failed or the alarm is activated.


In this category you find the systems that require either tags or smart cards to gain entry.  The base unit(reader) is mounted at the door / gate.  The individual would either swipe their card, or tap the card or tag depending on the type of reader.

These systems are often used in apartment buildings, offices, etc.  The downside is that an individual could give their card or tag to someone else, making it easy for anyone to gain entry.


As advances have been made in technology, and the demand for tighter security measures rise, many of the systems mentioned previously fall short when it comes to business access control.  Here is where biometric access control comes into play.  Within this category there are various levels of products available, from basic to advanced.

Starting out would be a simple unit that uses fingerprints to grant access.  The reader is linked to the maglock, and the individual needs to scan their fingerprint to gain access.  The fingerprint reader can also be combined with a keypad.

The next level would be face recognition.  Here you would need to scan your face to be granted access into the building / onto the premises.  Face recognition and fingerprint scanning can also be used in combination, where higher security measures are needed.

And with COVID 19 has come the need to ensure that maximum measures are taken to ensure everyone’s safety and health.  Many employers have implemented the use of biometric access control units that make use of face recognition and thermal imaging.  This means that the reader scans the face, but also takes the persons temperature.  Both criteria need to be met for that individual to gain access.  So should they be running a fever, they will not be allowed access.
