What Are The Different Types Of Access Control?

Access Control system are essential part of the total security system of any premises. They are the electronic system that are controlled through a network to which they have access. They recognizes an identity, authenticates it and then finally authorizes the entry of the identity. Thus, it provides complete protection from any trespassing or unwanted people at any business premises. Based on the type of situation and the need of the organization there are different types of access control systems. Some of the most important ones are discussed below.

Different types of access control system

As mentioned every organization has their specific security needs. To cater to that need there are various kinds of access control system available in the industry. In organizations where high security is necessary there are access control system like the door controllers, bio metric, card readers and others. Each and every access point are controlled by using different types of door access control systems. In order to use the access control system it is necessary that network security is maintained to the utmost.

Bio metric Access Control System

The most common if all access control system is the Biometric access control system. It is mainly used for maintaining time attendance which is captured by using the fingerprints of the employees. Through the software it can capture, track and record the data that are input by the employees as well as visitors.

In a biometric access control system the data is captured by finger prints and not by card system. This is the most importance different between them and the card access control systems. The basic purpose of use of both are almost same that is to capture the entry and exit timings. They are also used at different confidential places so that the entry to that place is permitted to a privileged few.

Proximity Access Control System

This is another access control system that is used at more confidential places. Whether used at offices, banks or factory they provide a safer environment. They are installed at any place in such way that a passerby will not able to see them. The proximity cards are handed over to those who have the privilege to enter the premises. When the cards are near the card reader they can read it and the doors open. The user do not have to swipe the card or use their fingerprints. When the cards comes in proximity to the system it gives access.

This type of control system is best for high security areas where the control system should not be disclosed to the passersby.  It is thus a security system that is quite tough to breach.

Door Access Control Systems

There are door access control system that are compact, standalone and low cost. They are ready to use and can be installed easily. They are mainly used at different places like the Server room, offices, data centers, airports and other.

Based on the type of building they are protecting they can be linked to a standardized location. Then they are administered from a central location. There are different types of door access control systems. Most common ones uses card readers for allowing the passersby to pass through while there are others that are more sophisticated and the entry is granted by an administrator.

Security Access Control System

Apart from authorizing someone to enter a building an access control system is also used for security purposes. Thus, there are various kinds of security access control system which are mainly used for maintaining the security of the place. The systems mainly have sensors which are paled at different locations of the premises, be that a personal home or office. When the sensor senses something it activates the alarm. In turn the alarm will connect to the automatic dialer for informing about the breach of security.

Some of the common type of security access controls system are closed circuit TVs, card access systems, infra-red automation and security systems and others. They can be wired or wireless based on the system that is used in the premises where the system is installed for providing security.

Modern access control systems

Technology is gifting mankind with something or other every other day and thus in access control system too there are wide innovations. There are something more than card access control systems where one can use their smartphones for gaining access to any room. By using the apps of the security access control system it is possible to allow someone enter the premises even when the owner is far away. There are even cloud based access control system where the total control can be managed from a central location. These are best for security managers who have to manage the security of multiple locations.

 

 

 

 

What Is Access Control System? How It Works?

In order to meet the various demand of modern offices and other premises access control systems are of great use. They are the techniques that are used for controlling the passage of an individual to and from any area. The simplest form of access control systems are the locks and keys that had been in use since ages.

With year the access control system has been innovated and have become sophisticated. Now they are more than just a lock and key and now they mainly refer to the electronic card access systems that are computer-based. Instead of the brass key, there are ‘access card’ which opens the locked door! The use of the access control system is not only limited to allowing entrance to any building but they can also be used to check the entry of individuals at any secured places. Those who are authorized to enter and pass the door can use their card reader for getting permitted through a building access control systems.

How does an access control system work?

There are different kinds of access control system and they perform differently. However, the basic structure of functioning of all the access control system is almost the same. In case of door access control systems, the access card should be swiped while in case of a proximity access control system the radio waves will read the cards and allow entry.

The total system in which an access control system works is divided into five phases.

Authorization

When the access control system is installed it considered everybody as a stranger. Through the process of authorization, the strangers are converted into members. For doing that it is necessary to define the company policy. The rights of an employee should be determined and that includes that who will be the employees getting access to which door. Like, the main entrance of the building will be open for all but that is not true for others specific places.

It is necessary that every assignee has been provided a role and there should be role-based access control. It is mainly given to the administrator who can control the roles of every employee.

Authentication

After the authorization process is complete the need of authentication arises. Every time a member wants to pass through the access control system need to authenticate themselves. They must present the door reader be it an access card, a badge or a token. After checking the credential at the token the reader will authenticate the user. Based on this process it will be decided that whether the lock will be opened or not.

The process of authentication is simple. After the system captures the code of the access card, whatever type it is, it matches that with the ones stored. There can be different criteria for this match like there may be a system where employees are permitted to enter the premises at any particular time period. They will not be allowed at any other time apart from that particular time period.

Access

After checking the credentials the time comes when the member will be given access. The access toll must ensure that everyone gets at the right door at the right time.

The first step for getting access is to unlock the door. After the card is validated the member can do that. After the request is done the access is triggered and then the door is unlocked. When the door unlocks different events are tracked. Like, the user who is authenticated is recorded along with the time of authentication. The door opens and then the door closes.

Manage

This is not the usual working of an access control system. This step mainly helps the administrator for controlling the whole thing along with adding new members or removing someone. There can be any problem that can troubleshoot by the administrator. If required when the office premises is enlarged new access points may also be added. This is not for the regular members but for the management who wants to control the whole system according to the policy of the business.

Audit

Again this is another function that is not used regularly but can be very useful. Those access control systems that are used for maintaining the incoming and outgoing time of an employee will help in preparation of the payroll of the company, sometimes the payroll software is also installed along with. Apart from that different data can also be collected.

In order to meet the requirement of the business the whole access control system should be audited. It must be ensured that the access control system is working as it should. It is required to be checked that nothing tampers in the meantime. This control must be done at a regular interval or else the utility of the access control system will reduce.
