What Is Access Control Technology?

Access control has been a very common technique extensively used from ancient times to restrict persons or risk factors from accessing any secure place, asset, or people. The human intervened techniques would be used in old ages, but numerous modern technologies have been adopted in the access control techniques nowadays. Despite the use of the latest technologies, the basic principle of access control is still all about restricting/granting access to who, what, when?

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.

When utilizing access control technology, you can always know:

  • Who can have access to your building.
  • The degree to which that person has control over its security.
  • That your business is safe from non-authorized threats.

Overview of Access Control Technology

The list of best access control technologies contains the technologies most commonly used for communication between the different components of an access control system (ACS). Therefore, let us briefly introduce the access control technology:

Near Field Communication (NFC): Two NFC-enabled devices establish a communication medium through an air interface. When they are close to each other, an electromagnetic induction field is generated between them. These access control devices operate at 13.56 MHz within 1.6 inches.

Internet of Things (IoT): This is IP-based communication between all components of access control technology. These components are smart devices that support IP. They use the Internet to establish communication between them.

Radio Frequency Identification (RFID): In this technology, credential information is stored on a label attached to the carrier. When approaching the reader device, electromagnetic waves are generated and captured to read information and allow/deny access.

Physical Access Control System (PACS): This is based on Personal Information Card Verification (PIV) cards and card readers. This technology is used in government and security related fields. It involves a two-step verification process.

Power over Ethernet (PoE): This technology uses cables that transmit data signals and power to power access control components such as IP cameras, phones, access controllers, routers, access points, and other elements. This is a very cost-effective access control technology.

Mobile access control: Convert the mobile device into an electronic key fob by installing an application that uses wireless technology to communicate on the mobile device. Mobile devices can also be used to manage and control the entire access control system of a specific area or building.

Bluetooth access control: This uses the power source of the Bluetooth-enabled device. Data is transmitted between two devices through a frequency hopping spread spectrum radio interface, which works in the ISM frequency band. It has an effective distance of up to 800 feet and a data rate of 50Mbit/sec.

Wired access control technology: including CAT6 cable communication, PoE access and traditional wiring solutions. Communication between different components can be carried out through different communication protocols.

Wireless access control technology: This is a broad category of wireless technology used in access control systems. Bluetooth, NFC, RFID, mobile devices and other technologies belong to this type of access control technology.

The overview of access control technologies in each category can be further expanded in terms of features and capabilities to integrate different back-end technologies and software applications.
