What Are The Components Of A Door Entry System?

It may not sound the most exciting title for a blog, but if you’re not an access control installer, how are you supposed to know what components you should be asking for in a quote to upgrade your door entry system?

Door entry systems are integral to the security and convenience of many buildings, ranging from residential flats to commercial premises. By controlling and monitoring access, they offer peace of mind and flexibility. In this blog post, we will explore the different components that constitute a door entry system and delve into how they function in unison.

Door entry systems components, often referred to as access control systems, work together as a mechanism designed to manage and restrict entry to a property. These systems have evolved significantly, from traditional mechanical locks to advanced electronic and biometric solutions. A door entry system’s principal role is to secure access, ensuring that only authorised individuals can enter. It provides a convenient way to control entry without the need for physical keys.

The progression from basic locks and keys to sophisticated systems encapsulates technological advancements in security. From mechanical locks to electronic keypads and biometric scans, various types cater to different security needs and budgets.


Key Components of a Door Entry System

The complexity and functionality of a door entry system lie in its components and how they synchronise with the other components ensures seamless operation.

The key components of a door entry system are:

Access control credentials:

These are the physical or digital items that are used to identify authorised users of the system. Common types of access control credentials include:

  • Keys: the most basic and oldest form of access control credential remain the most widely used.
  • Cards: RFID cards, proximity cards, and smart cards are all types of physical access control cards.
  • Key fobs: Key fobs are small devices that contain an RFID chip or other type of electronic identifier.
  • PIN codes: PIN codes are a type of digital access control credential that is typically entered on a keypad.
  • Biometrics: Biometric access control systems use physical characteristics, such as fingerprints or facial scans to identify authorised users.

Access control readers or scanners:

These are the devices that are used to read access control credentials. Access control readers can be either standalone devices or integrated into other devices, such as door locks or intercoms.

Locking mechanisms:

These are the devices that are used to physically lock and unlock doors. Locking mechanisms can be either mechanical or electronic. Modern door entry systems utilise various locking methods, such as deadbolts, magnetic locks, electromagnetic locks, and strike locks.

Control panel:

This is the central unit of a door entry system. The control panel is responsible for receiving input from access control readers and controlling the locking mechanisms.

Access Control Software:

Door entry systems, unless they are very basic, typically require software to manage user access and track access logs.


The specific components of a door entry system will vary depending on the type of system and the specific needs of the organisation or building. For example, a system that is used to control access to a secure facility will have more complex components than a system that is used to control access to a residential building.


Integration and Functionality

A well-designed door entry system ensures that all components work together cohesively. Integration creates a user-friendly experience and robust security. Customising the system to individual needs enhances functionality, while regular servicing ensures optimal performance. Maintenance and reliability are vital to ensure that the door entry system functions smoothly over time.
