Introduction to Access Control
The purpose of access control is to grant entrance to a building or office only to those who are authorized to be there. The deadbolt lock, along with its matching brass key, was the gold standard of access control for many years; however, modern businesses want more. Yes, they want to control who passes through their doors, but they also want a way to monitor and manage access. Keys have now passed the baton to computer-based electronic access control systems that provide quick, convenient access to authorized persons while denying access to unauthorized ones.
What is Access control and how is works?
Access control is a security technique that regulates who or what can view or use resources in a computing environment. It is a fundamental concept in security that minimizes risk to the business or organization.
There are two types of access control: physical and logical. Physical access control limits access to campuses, buildings, rooms and physical IT assets. Logical access control limits connections to computer networks, system files and data.
To secure a facility, organizations use electronic access control systems that rely on user credentials, access card readers, auditing and reports to track employee access to restricted business locations and proprietary areas, such as data centers. Some of these systems incorporate access control panels to restrict entry to rooms and buildings as well as alarms and lockdown capabilities to prevent unauthorized access or operations.
Access control systems perform identification authentication and authorization of users and entities by evaluating required login credentials that can include passwords, personal identification numbers (PINs), biometric scans, security tokens or other authentication factors. Multifactor authentication, which requires two or more authentication factors, is often an important part of layered defense to protect access control systems.
Today, instead of keys, we carry access cards or ID badges to gain entry to secured areas. Access control systems can also be used to restrict access to workstations, file rooms housing sensitive data, printers, as well as entry doors. In larger buildings, exterior door access is usually managed by a landlord, or management agency, while interior office door access is controlled by the tenant company.
People new to access control may think the system is made up only of the card and the card reader mounted on the wall next to the door. There are a few more parts behind the scenes, all working together to make the magic of granting access to the right person. That’s what this guide is about. Reading it will give you a full and comprehensive understanding of how access control systems work and the language required to communicate with vendors.
Is it absolutely necessary that you learn about access control yourself? No, definitely not. But it will save you time if, in the middle of your project, a problem arises or an important choice must be made. You can seek advice from the installers but they’ll likely answer in access control language; however, you don’t have to take a crash course or call a security-control consultant just yet. But when you do, it helps to have a basic grasp on the subject and your education is free when an online search turns up a resource like this.
How Access control system is used?
Access control system are connected their servers using multiple technologies which includes Cloud servers, Wired network, wireless network and IOT based system.
LAN and Optical Fiber technology
Mobile and Smartphone-based access control system
IOT-based access control system
Cloud-Based Access Control:
In the access control technology, the access permissions are not stored on a local server, but in the cloud. This means that the administrator can manage the permissions from home, or while on vacation anywhere, simply by using a browser. This appeals to security managers charged with overseeing multi-location facilities. It can be done using Emails, online softwares.
Mobile or Smartphone based system:
Mobile or smartphone access control works on the same principle as mobile accessed email, once an app has been downloaded, users are able to access and respond to their mail as long as they enter the correct sign-in credentials. The same is true for smartphone-based access control. Once authorized, and users have downloaded the access control app to their smartphones, they’re able to do the same thing; namely, sign in with their user account, and as soon as their authorized keys appear, select which door to open. The difference with Kisi, for instance, is that they just hold their phone to a Bluetooth or Near Field Communications (NFC) reader, and the door will unlock, but the permissions (log-in credentials) are checked in the background, just like sending an email.
IOT based access control system:
Wired technology: It is the most trusted technology by the users and integrators as it is not dependent any third party and it creates its own network. Access control lock, readers are connected with the server using the Lan wire or the optical fibers. Even though it’s a wired network but it has got no limitation related to the access of the servers from a remote site. It is also trusted as when the system works on Intranet then it keeps the system safe from the cyber threats and intrusions.
Explanation of how it works?
- AUTHORIZATION – Authorization is the phase that turns strangers into members. The first step is to define company policy; determine what people can and cannot do. This should include who has access to which door(s), and whether members of the organization can share access.
- AUTHENTICAION – Authentication goes one level deeper than authorization. In this phase, members present to a door reader whatever badge, token, or credential they were given upon being authorized. The reader will check its validation to determine whether or not it should unlock the electric lock on the door in question.
- ACCESS – Now that the credentials have been authenticated, the access tools available at this stage make sure everyone gets in the right door, at the right time, faster and easier.
- MANANGE – This phase helps the administrator meet several challenges, including adding new access points, onboarding and offboarding users, maintaining security, and troubleshooting problems. Let’s examine some advantages.
- AUDIT – Auditing physical access control is useful for all types of businesses. In addition, it helps certain sectors meet special requirements.

Door Access Control :
A door access control system determines who is allowed to enter or exit, where they are allowed to exit or enter, and when they are allowed to enter or exit. This was partially done through readers, keys and locks. Only authorised people are allowed to come inside the premises.
The term access control often brings images of access controlled doors, vaults, secure elevators, buildings and secret places. However, today’s access control also includes rooms, workstations, file cabinets, desk drawers, along with equipment like printers or computers.
A typical system has two major components: One controlling the access to a physical location and a system verifying the presence of authorized personnel. The electronic access controlling the physical location, such as a door, typically contains several elements: The lock, the reader, a control panel to authenticate the credentials, along with access control hardware and software.
CRASH RATED SECURITY BOLLARDS:
The rising bollard comes with a push-button hold to run control as standard.
The bollard system can be customised to interface with a wide range of access control equipment to suit specific customer requirements. Available configurations include (but are not limited to) inductive loop systems, card readers, communication equipment and manned guard emergency systems.

This allows an automatic opening for two wings while people walk through the gate with the access cards. After that, it closes down in a minute. The flap barrier is composed of a chassis, core component, wing arms, Printed Circuit Board (PCB), infrared sensors, reader, and access control system. The system uses standard electric interfaces. It meets fire-fighting passage requirements and is equipped with dedicated fire control linkage interfaces. The entire system complies with the same quality standard to ensure reliability, stability, and smoothness of the system during operation.
How Flap Barrier works?
Flap Barrier gates have a simple working principle. Flap barriers manage the crowd on the industrial places like Exhibitions, supermarkets, metro, and public transports. It is utilized mostly for Business and industrial places. The Method of an Automated Security Gate or Flap Barrier varies in Size, Shape, and Performance. Flap barriers are works with illuminated wings that can move or control by bi-directional movement. Flap Barrier gates provided with a sensor to the prevention purpose. The mechanism provides the feature to the gate wings can automatically open and hide. RS232 serial communication port is used to control the opening of the barrier After the signal received by the card access, the system automatically closes the flap barrier after few seconds. Flap barrier provided with an Anti-pinch function which protects a person against injury caused by the closing of wing arms at the end of the preset pass-through duration.
After powered on, the flap barrier main board performs self-test to check whether the hardware works normally. If any failure is detected, the system will display a text prompt on the LCD screen. The user can quickly solve the problem based on these prompts. After the reader receives valid user information, the control panel sends barrier opening signals to the flap barrier main board. The flap barrier main board receives, judges and processes the information from the control panel, the infrared correlation tubes and the proximity switch, and then sends commands to the upside indicator light and the electric motor. The upside indicator light turns from red to green and the electric motor is activated to open the flap barrier so that the pedestrian can pass through the channel. This system can also be integrated with the third party systems like CCTV, access control and command & control system.

Under Vehicle Surveillance System:
UVSS provides unique facility to scan the hidden area of the Vehicle which cannot be easily monitored or seen by the security officials. Security and surveillance system is complete without the ability to scan the area underneath the millions of vehicles entering and exiting high-risk areas every day.
UVSS is widely used in public establishments such as Sensitive Defence areas, Govt Offices, Public transport areas, malls and large corporate offices buildings with a steady stream of vehicular traffic entering and exiting, operate a most primitive and highly ineffective system of handheld reflective mirrors shoved briefly under a car. Besides being clumsy, it also slows down vehicular movement, causing delays.
Under Vehicle Surveillance System (UVSS) is the perfect solution for such establishments that need to thoroughly check under dozens or hundreds of vehicles every day without slowing down vehicular passage. This system is capable to scan, monitor and digitally record crisp, clear digital video and images of the entire width of a vehicle’s underside. Our surveillance cameras which are enabled with the Artificial inteilligence system detects the foreign objects and threats to help you to mitigate risks. UVSS is a fully automated system that does instantaneous inspection of vehicle undercarriage using digital line and area scanning technologies, and triggers an alarm if its scan detects doubtful elements, including explosive devices.
It can be fixed permanently into the ground to inspect vehicles passing above, or it can be mounted on a mobile unit to be used manually or robotically at flexible locations.
How UVSS works?
The Under Vehicle Surveillance System works with Automatic Number Plate Detection camera and High resolution cameras which gives security officials a clear, sharp images of the vehicles undercarriage. It also uses the Bright white, high-intensity LED-based lighting illuminates the vehicle’s undercarriage so details are not lost in shadows and the hidden objects are easily seen through the camera. It uses color area scanning technology to effectively scan and inspect the undercarriage of vehicles to search and analyze images for explosive devices, suspicious objects or contraband such as drugs and weapons. And with the ability to place cameras anywhere along the length of the ramp, wheel wells and other details are easy to capture. Focal length, field of view, and angle of the camera simulate a person in a pit viewing vehicles passing over. The video is then transmitted to the Server for deep analysis using the artificial intelligence and then the software can easily trigger the alarm in case of any hidden object found.
For better results, UVSS system in installed with either Bollard and boom barrier system at the entry and exit of the premises. UVSS is also used with ANPR and Visitor management system. As soon as the vehicle comes to the entry point, ANPR reads the Vehicle no and informs the security official regarding the same and the vehicle no is sent to the server for its authorization and if the vehicle is authorized to entry then the Boom barrier will automatically open and the vehicle will pass over the UVSS and the security official will see the undercarriage photo and video of the vehicle, in case of no suspicion and no foreign object the vehicle will be allowed to come in the premises. It can be easily understood from the below diagram.
