Physical Access Control Systems: What Are They?

In today's complex landscape of security threats and compliance issues, implementing effective physical access control is more critical than ever. Whether managing a manufacturing plant, a bustling warehouse, or a high-security data center, restricting access to authorized personnel is essential for maintaining security and operational integrity.

In this article, we'll explore the crucial components of physical access control systems (PACS), different types, benefits, and why modern facilities can't afford to ignore this vital security measure.

What is Physical Access Control?

Physical access control systems are designed to regulate the entry and exit of people within a facility. Unlike traditional locks and keys, physical access control systems utilize advanced technologies like key cards, biometrics, or mobile credentials to ensure that only authorized individuals can gain access to specific areas. This is especially important for environments like industrial plants, warehouses, government facilities, and other high-security environments, where designated areas, sensitive information, and valuable assets need to be protected from unauthorized access.

Components of a Physical Access Control System

A robust physical access control system is comprised of several key components, each playing a crucial role in ensuring comprehensive security:

• Access Points: These are physical points of entry including doors, turnstiles, and gates that control entry into areas (where a visitor first interacts with the PACS). Modern access points are often equipped with smart locks and sensors that provide real-time data on entry and exit activities.
• Credentials: Credentials are a means of identifying a person. They are used to allow the system to know who is trying to gain access and what access to grant based on their identity. Credentials can come in various forms, including key cards, fobs, digital certificates/IDs, or biometric data. Digital certificates and IDs are becoming increasingly popular due to their enhanced security features and ease of management. Biometrics, including fingerprint and facial recognition, are also gaining traction due to their high level of security and convenience.
• Credential Readers and Control Panels: These devices are used to determine what action the system should take, by reading credentials and sending electrical signals to control panels to grant or deny access. These components must be reliable and quick to ensure seamless access for authorized personnel.
• Integration Layers: The ability to communicate with other third-party systems is a vital component of access control systems. It offers users the ability to connect to other core technologies. There is a wide range of tools that a company may want to integrate with. For example, integrating with a visitor management system, like iLobby’s VisitorOS, enhances physical access control capabilities by providing seamless visitor management.

While PACS primarily focus on regular occupants, integrating a Visitor Management System (VMS) provides access to a list of temporary guests, contractors, and other on-site visitors. The data made available with such an integration provides a seamless, end-to-end solution for managing facility access for all. A VMS like iLobby's VisitorOS can streamline and automate the check-in process, ensure compliance with visitor management and security protocols, provide real-time visibility into who is present in the facility at any given time, and can be used to enrich access control solutions.
