ACCESS CONTROL SYSTEMS AND ALL YOU NEED TO KNOW

1500 0

The term access control refers to the practice of restricting entrance to a property, a building, or a room to authorized persons. Physical access control can be achieved by a human (a guard, bouncer, or receptionist), through mechanical means such as locks and keys, or through technological means such as access control systems like the man trap.

The Elements of Access Control Systems

Access control can be broken down into three core elements. Essentially, these distinct elements define how access control systems work.

  • Identification

The main aim of an access control system is to protect your building from unauthorized access and control the movement of people within. For this reason, the system must enable you to determine the identity of any individual entering the building or accessing any of the secure areas within the building.

  • Authentication

After the system has identified an individual, it is imperative that his/her identity is authenticated to ensure that only the right persons are granted access. You can achieve authentication using a variety of methods including passwords, encryption keys, smart cards, and fingerprints.

  • Authorization

With successful authentication, building access control systems are able to grant individuals, access to the building or other restricted areas, based on the set criteria.

How Access Control Systems Work

When a piece of information is presented to an access control system, the system reads it and sends the information, usually a number, to a control panel, a highly reliable processor. The control panel compares the data to an access control list, grants or denies the presented request, and sends a transaction log to a database.

When access is denied based on the access control list, the door remains locked. If there is a match between the credential and the access control list, the control panel operates a relay that in turn unlocks the door.

The control panel also ignores a door open signal to prevent an alarm. Often the system provides feedback, such as a flashing red LED for an access denied and a flashing green LED for an access granted.

Types of Access Control Systems

The number and type of access control devices vary based on the complexity of the system. There are basically three types of access control systems that are available in security systems.

Basic access control systems.

With these systems, users gain access by inputting a PIN into a keypad which then triggers a locking mechanism to unlock the door. The system does not make decisions about who is permitted to enter but simply gives access to anyone with a code.

Semi-intelligent access control systems.

These systems have everything necessary to control a door (access to a lock, a magnetic door contact, and an exit button) but do not make access decisions based on who is trying to get in. If a person presents a card or enters a pin, the reader relays information to the main controller and awaits a response. These systems can be adjusted to allow certain people access to certain places, but always requires a person to input that access into the controller.

Intelligent access control systems.

Controlling access points like semi-intelligent readers, intelligent readers take the technology a step further by connecting directly to a PC that can fully integrate access information, track a person’s whereabouts, time signatures and activities and provide an owner with an overall picture of what is happening while they are gone. Intelligent readers are especially useful in home security systems where people can check up on their home, kids or pets remotely from their smartphone.

Integration

One of the biggest advantages that you need to take into consideration when getting an access control is the integration capabilities that it offers the recipients with. Many organizations whether it public or commercial use a variety of systems throughout their organization, many of which need different forms of tokens to be controlled. Access control ID cards can be programmed to integrate with existing in-house systems such as vending machines, barriers, catering, print management and even PC’s. They also double up and act as an ID card where various information and images can easily be printed on them.

keep tabs on staff

If you are a business owner who has employees or contractors, like janitorial staffs who tend to work more than the normal working hours, you can restrict their access to hours and days when they absolutely need to be there.

Additionally, every office might have employees that can have access to only particular areas that are important for their work, and not others. This is crucial in restricting access to sensitive areas or data to only those with the need and clearance to know. An access control system has the power to program ID credentials to limit access to certain areas only.

Activity monitoring and reporting

An access control system will take note of every person who walks in and out of your door throughout the day. If in an unfortunate circumstance a criminal or intruder were to trespass your premises, this log will prove invaluable in resolving the cases. It can also monitor areas like the card clocks to resolve any timekeeping issues that you might be experiencing. Furthermore, the reports can be generated to determine employee tardiness and other issues that decrease productivity.

Employee protection

In present times threats are endless, you never know what kind of people walk through your door. To avoid breakthroughs you need to get an access control system for your premises. This way you will be able to successfully prevent the unauthorized individuals from entering the premises, protecting the people who are supposed to be in there working for you.

You will have peace of mind that will increase your job satisfaction and productivity. When your staff feels they are safe from harm during their work hours, they will be able to give in their best every day when they come to work and that will boost the overall productivity of your business.

No more hassle of duplicating the keys

Every single time you duplicate the key to your building, you are taking a risk, that way an individual other than you can access your property. Sure, you can make them “non-reproducible”, but there are always ways of getting around that. All it takes is one disgruntled employee to create a situation that can have devastating results, like theft, vandalism, and even more serious criminal activity.

You might have to change the locks every single time an employee leaves the organization, this option could prove to be highly expensive and it still won’t stop the current employees from sharing the keys if they wanted to.
