Access control reader

What is an access control system?

Access control devices are useful for checking who wants to enter the company premises. They enable the automatic identification of persons moving through company buildings. They are mounted on doors, gates or barriers. They can be used to record movement within individual rooms as well as entire buildings or even complexes of buildings.

What are the components of time and attendance software?

Fully autonomous and effective professional access control is only possible if the system is based on appropriate hardware and software. A server and access controller are required, as well as built-in readers and electronic locks.

Server

The central element of the T&A system is the server. Using a special interface, it is possible to:

• grant and modify powers, for example in terms of access levels;
• collect data on the use of readers, including in terms of time or place.

A server allows you to manage the entire system efficiently and react quickly to security breaches, for example. It is necessary for all devices to be integrated with each other and to function properly.

Control unit

An access control alarm system will not function effectively without a control unit. Control unit decide whether to grant or refuse access. Everything is done automatically, without the need for user intervention.

Access controller

Access to the premises is via a special reader. It allows reading the identification data of a person who intends to enter a specific building or room. It is he who, after contacting the control panel, is responsible for access to the zone. In the overall system, it therefore plays a fundamental role.

The transponder operates with network communication interface. It uses different standardy, such as:

• RS-485 - It is ideal for wide-area and distributed networks, as well as in harsh environments, such as industrial environments;
• TCP/IP, which will ensure compatibility with a wide range of computer systems, facilitating the integration of individual devices within access control;
• Mifare - The proximity card reader in this standard has a powerful chipset and a sizable memory, so it works quickly; it also has the advantage of a long communication range of up to 1 m.

In addition, there are readers available on the market for opening doors that operate using technology Bluetooth. Some can be operated from a mobile app, which is very convenient and streamlines the management of the entire system.

Whether access control readers are to be used on the warehouse floor or in an office or hotel, it is worth using durable and reliable cards or key fobs. renowned manufacturers, For example, Roger or Satel brands. Electrically powered devices are best with battery back-up, which, after a power cut, will allow operation for up to 72 hours. This is important, for example, in the event of a fire when evacuation must be carried out quickly. Before buying readers, pay attention to whether they have appropriate protection class. Optimally, this should be IP65.

Electronic locks and other system components

In order to be able to open the door once the access controller has read the credentials correctly, the door must be fitted with an electromagnetic lock. This will allow receive the signal from the reader and release the lock at the appropriate moment.

Each access control system should also be equipped with:

• input sensors, which are mounted on the inside of the room - allow users to leave the protected area;
• reed switches, which are sensors that indicate when a door has not been closed.

For access control to work properly, all components must be operational and properly configured. Professional installation and proper maintenance are essential. It is advisable to entrust this task to a specialist company.

What readers can an access control kit contain?

Reader manufacturers are offering increasingly functional and sophisticated cards or readers for access control management. The most popular are those that allow doors to be opened when a special card is brought into proximity, and also when the user is identified by a fingerprint or PIN code.

RFID or Bluetooth proximity reader

This type of controller allows opening the door or barrier with the proximity of a special card or key fob. Among its key advantages are that:

• works without contact, which is very important in medical facilities, for example;
• is easy to use;
• can be operated for many years, regardless of the intensity of use.

A proximity card can work on the basis of RFID, i.e. radio frequency identification (the Unique 125 kHz standard is often used), or Mifare or Bluetooth. Some devices have built-in internal memory, so that data can be saved, and voice messaging system. They may also have a keyboard or camera.

Code access controller

Such a reader on the case has a keypad where the PIN code is entered. Only after it has been approved can the door be opened. If you use this solution in your company, it is worth changing the access codes from time to time. This will have a positive effect on security.

Biometric reader

The following are also used in access control systems fingerprint reader or iris scanner. Also available face recognition. This type of authorisation is very beneficial for the company as it ensure the highest safety standards. There is no risk, as with other types of reader, of an unauthorised person gaining access to the protected area as a result:

• theft or copying of a proximity card;
• using a PIN code that was accidentally or deliberately given to such a person by an employee.

Some transponders allow for two-step verification. Additional security can be provided by a mobile badge, for example.

UHF reader

The access controller, which uses radio waves at 300-3000 Mhz, has a long range, up to several metres. Great for a large logistics facility, such as a warehouse or distribution facility, or a car park, among other things.

What is the card and key fob operation of an access control system useful for in production plants or hotel buildings?

The access control kit can be used in any company. It doesn't matter what industry or type of business you are in. It is always useful if you care about risk mitigation:

• access to buildings and premises by unauthorised persons - This is very important, for example, in areas where hazardous materials and substances are present;
• theft of company equipment or documents.

A proximity or biometric reader is a great solution to improve staff performance. If they move between different rooms, they do not have to waste time using traditional keys or searching for them with other people.

When you are a business owner, with the help of readers you can account for staff time. The system collects information on when they start and finish their work duties. This will make it easier for you to keep a record of the time they spend at the company and help prevent possible abuse in this area.

Proximity cards and RFID or UHF readers will also affect cost savings. This is because you do not need to employ a security agency and replace the locks on your doors if your keys are stolen or lost or your employees leave. The price you have to pay to purchase an access control system is a relatively small cost compared to the benefits you will gain from it.
