How Does An Access Control System Work?

An access control system is a security system that helps to restrict access to unauthorised people and/or areas. It can be used to control access to buildings, rooms, computers, and other sensitive areas.

Benefits of Access Control Systems

There are many benefits to using an access control system, including:

  • Increased security: Access control systems can help to deter crime and unauthorized access to sensitive areas.
  • Improved efficiency: Access control systems can help to improve efficiency by reducing the need for security guards and by making it easier to track who is coming and going.
  • Reduced costs: Access control systems can help to reduce costs by simplifying entry requirements to sections of your premises in addition to simplifying management of a business’ security.
  • Compliance with regulations: Access control systems can help businesses to comply with regulations, such as those related to data protection and privacy.

How Access Control Systems Work

Access control systems typically use a combination of hardware and software to control access. The hardware includes the access control panels, readers, and locks whilst the software includes the access control software and the database of authorised users.

Types of Access Control Systems

There are many different types of access control systems, including:

  • Biometric systems: Biometric systems use physical characteristics, such as fingerprints, facial recognition, and palm prints, to identify users.
  • Card-based systems: Card-based systems use cards or tokens to identify users.
  • Proximity-based systems: Proximity-based systems use radio frequency identification (RFID) tags to identify users.
  • Key-based systems: Key-based systems use keys to identify users.

Choosing an Access Control System

When choosing an access control system, it is important to consider the specific needs of your business. Some factors to consider include:

  • The size of your business: this will influence the number of doors and users that you need to install the access control system around.
  • The type of security that you need: this will be dependent on the level of security that is required for your business.
  • Your budget: the cost of an access control system will vary depending on the type of system that you choose.


Access control systems can provide a number of benefits for businesses of all sizes. Choosing the right system to compliment your needs can elevate the security of your business whilst reducing costs.
