Door Access Control and the Security it can Provide You
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 always the first things considered when security measures are being discussed.
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 businesses 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 you are granted 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 and How They Work
Not too long ago, a well-made lock and chain was considered 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, and while it has assisted would-be villains in creating higher forms of theft and threat, it has also been adapted to provide more effective business security systems.
Access control is a form of security that is used to identify specific individuals, authenticate them, and give them access to the door or workstation that they need access to. Within the door security sector, there are certain pieces of hardware that work together in order to provide the accessibility or lack there of that these systems use to function.
These pieces of hardware include:
In newer versions of access control: smartphones
There are two basic versions of security cards most companies like to use, that come in two sizes: one that can fit in your wallet like your bank cards and one that is thicker and laminated and is usually worn around the neck. These cards come with barcodes that have a specific identity or serial number imbedded into them that can be read and used by certain door readers.
Like other components of access control such as optical scanners, capacitive fingerprint scanners generate an image based on the specific patterns that make up a fingerprint. However, instead of sensing these fingerprints using light, the capacitors use certain electrical current.
Door readers use certain credentials that have embedded circuits and an antenna. 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.
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 are instructed to download a specific app on their phone which will be programmed with the appropriate permissions for that specific user.
Business 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 a few 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 is started when the reader broadcasts a signal that is received by the credential antenna. This electrical signal from the door reader contains enough power to energise 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: 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 recognise 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 systems, there are certain questions concerning the access control installation that every business owner should answer first:
The purpose of installing an access control system should be clear, and is based on the security level that a particular company might require for their installation.
This is a very important factor of access control installation,in which the user should have a complete assessment of the system so that he/she can achieve the objectives they are looking for.
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 screen or in some cases a combination of two or more.
Cost is always a very critical component to consider when it comes to selecting a good business security systems and the included installation. You should not invest more for securing less valuable assets and should not invest less for high value assets.
Door access control systems are always a fantastic addition to any business security system, and moving forward it could be your best choice when wanting to secure your establishment.
Controlling Your Company’s Future Professionally Through Door Access Control
It is normal for business owners to have worries and stress over the wellbeing 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, and the variables are something we all have to work with.
Access control provides peace of mind - your world can change, as can the faces you see everyday, but when using effective door access control, you can still have the control you need over what matters most.
