Access Control Security Systems for Your Campus

On a daily basis, people all over the world spend a decent amount of their time opening and locking doors. It is happening constantly – even while you read this. Locks are the first things to consider when discussing access control security systems.

Among the more advanced safety measures now available, access control is swiftly becoming one of the smartest and most adaptable. With capabilities ranging from retinal scanning and facial recognition to malware and virus protection, more and more companies are choosing to protect their campuses with access control. We’ve all gone through a door that requires a form of identification in order to open it, be it fingerprint scanning at the bank or keycards in your office building – these types of entrances and exits are becoming more and more common. 

But how do they actually work? 

Not many people take the time to figure that out. It works, and as long as they grant you access, it doesn’t really matter. Gaining a better understanding of how something actually works can be useful, though, enabling you to make better decisions.

Door Access Control Security Systems – How They Work 

Not too long ago, everyone considered a well-made lock sufficient for keeping our valuables and assets safe. But in the days since, the world has progressed and changed, sped up and become more complex. Technology is at the forefront of that change. While it has assisted potential villains in creating higher forms of theft and threat, it has also adapted to provide more effective campus security systems.

Access control is a form of security that identifies specific individuals, authenticates them, and gives them access to the door or workstation that they need access to. Within the door security sector, there are pieces of hardware that work together in order to provide the accessibility or lack thereof that these systems use to function. 

These pieces of hardware include: 

  • Security or key fob cards
  • Fingerprint or biometric scanners
  • Door readers 
  • Physical locking mechanisms
  • In newer versions of access control: smartphones

Security Cards

There are several basic versions of security cards most companies like to use. They come in various sizes and are customizable for your needs. These cards come with barcodes or RFID chips that have a specific identity or serial number embedded into them that is read and used by door readers. 

Fingerprint Scanners 

Like security cards, biometric scanners use criteria to provide specific people access through an entryway. But instead of using a physical key, they use a biological identifier such as a fingerprint or retinal scan.

Door Readers


Door readers are the physical pieces of hardware on the door that read the credential (like a key card, fingerprint, etc.) to deactivate the lock.  They are powered by their own data cables, even when WiFi enabled. In newer models, they are capable of connecting directly to a company’s network and holding the identification codes for all the people assigned to the system. They can work even if the organization’s network is down and the central management software is unavailable.

Smartphone Capabilities 

Even though this function is more modern, it works in a similar fashion to security cards, with a reader installed at a company’s entrances. Users have to download an app on their phone which will be programmed with the appropriate permissions for that specific user.

Access Control Security Systems – Fitting It All Together    

When a person approaches a controlled access door and presents their form of identification (e.g. their security card), there are things that happen in the few seconds it takes for the light to turn green and the lock to disengage. 

The RFID door readers use specific credentials that have embedded circuits and an antenna within the system. The process starts when the reader broadcasts a signal that the credential antenna then receives. This broadcasted electrical signal from the door reader contains enough power to energize the circuit in the credential. Once the electric circuit in the credential receives the power it needs, this is then sent back to the access control reader that includes the required identification (ID) number. 

In terms of fingerprint scanners, the sensor is connected to an integrator. This is an electrical circuit built around an inverting operational amplifier. The inverting amplifier used in these systems is a complex semiconductor device, made up of a number of transistors, resistors, and capacitors. 

Lastly, the smartphone app;  the major variants of smartphone access control system include IP systems, control panel systems, and mobile access credentials. After downloading the app, the reader can recognize each user according to their credentials and allow them access where applicable. 

Door Access Control Installation Specifications 

Before deciding to make use of door access control security systems, there are certain questions concerning the access control installation that every campus head should answer first:

Objectives
The purpose of installing an access control system should be clear. It is based on the security level that a particular company might require for their installation. 

System Type
This is a very important factor of access control installation. The user should have a complete assessment of the system so that he/she can achieve the objectives they are looking for.

Authentication Type
A company owner needs to ensure they select the most powerful and most suitable types of authentication for their specific system. This includes biometric, key fobs, electromagnetic cards, keypads, touch screens, or in some cases, a combination.

Cost
Cost is always a very critical component to consider when it comes to selecting good security systems that include installation. You should not invest more in securing less valuable assets and should not invest less for high-value assets.

Door access control systems are always a fantastic addition to any campus security system, and moving forward it could be your best choice when wanting to secure your establishment.

Controlling Your Company’s Future with Access Control Security Systems

It is normal for campus heads to have worries and stress over the well-being of their company and employees. The world is constantly changing and new threats crop up when we least expect them. 

However, this does not need to be the ruling thought on your mind. Security is always evolving and has become stronger and far more effective – especially when used right. Door access control systems were created for this very reason. Unfortunately, we can’t be in all places all at once. The variables are just something we all have to work with. 

Access control provides peace of mind. Your world can change, as can the faces you see every day. But when using an effective door access control security system, you can still have the control you need over what matters most.
