What Is Access Control and How Does It Work

Access control refers to the method of managing who can enter certain areas of a building or site. It helps keep people and property safe by allowing approved individuals to access specific locations while keeping others out. Systems can be as simple as keypad entry or as advanced as biometric readers linked to a central control unit.

Below is a breakdown of how access control works, the main types available, and why it is important for safety and security.

Defining Access Control

An access control system manages entry points within a property by allowing or denying access based on predefined permissions. These systems can be electronic or manual and are often used to limit entry to restricted zones, track movement, and monitor the time people enter or leave a location.

They are typically used to:

• Stop intruders or unauthorised persons from entering specific areas

• Allow staff or visitors with permission to access the areas they need

• Log the movements of people for security and compliance purposes

Why Your Business Needs Access Control

Access control plays a vital role in creating a safer environment for your team and visitors. By restricting who can enter your premises, you reduce the risk of theft, vandalism, and unauthorised access. It also gives you greater control over sensitive areas and helps you maintain better oversight of your operations.

How Access Control Systems Operate

A typical setup involves three main steps:

1. The owner or site manager sets access rules, defining who is allowed where and during what times

2. Each person is given a form of identification, such as a card, fob, or biometric profile

3. Access readers at entry points check the credentials and decide whether to grant entry

This process keeps access secure and traceable, allowing you to review logs or revoke permissions if needed.

Types of Access Control Systems

There is a wide range of access control systems available. The right choice depends on your security needs, the layout of your building, and your available budget. At Winstanley Electrical, we offer solutions for all kinds of premises including commercial, industrial, and residential properties.

Key Card or Fob Systems: Used by many businesses, these systems issue staff or residents with cards or fobs to open doors. Permissions can be adjusted quickly, and lost cards can be deactivated without delay.

Biometric Systems: These rely on fingerprint, facial recognition, or iris scanning to identify a person. They offer a high level of security and remove the need to carry physical passes or remember codes.

PIN Code Entry: This method uses a keypad and a unique code to unlock doors. It is straightforward to set up and manage, though it is best used in lower risk environments.

Automatic Gates and Barriers: Ideal for controlling vehicle access in car parks or private sites. These can be operated through cards, remotes, or number plate recognition and are often paired with other access systems for added control.

Fully Integrated Systems: Larger premises or higher risk sites often benefit from fully integrated setups. These combine access control with CCTV, alarms, and emergency response features for a complete security solution.

Summary

Access control provides an extra layer of safety and control for your site. Whether you manage a small business or a large facility, these systems help you stay on top of who is entering and leaving your property. At Winstanley Electrical, we design and install tailored access control solutions to suit the unique needs of each client.
