Security is an aspect of business that more and more companies are taking seriously, and modern access control systems – especially those with digital and cloud-based capabilities – are fundamental to minimising risk.
Thoughtful security protocols create restricted areas and protect people, property and assets. Physical barriers prevent people from inadvertently entering sensitive environments or spaces containing hazardous materials and equipment, and help protect organisations from vandalism, theft and trespassing. Access control is especially useful in facilities that require higher levels of security and accountability.
For many small businesses, security is often an afterthought. But as companies grow, the stakes get higher. They start to consider improved security, run risk assessments and form a plan. A key part of that plan is deciding which access control systems and physical security controls to use.
What Is Physical Access Control?
In simple terms, physical access control creates barriers that prevent unauthorised people from entering your workplace or specific secure spaces within your facility. It’s the backbone of physical security: a combination of physical barriers, authority rules and authorisation plans that allow the right people in – and keep everyone else out.
Physical Security Access Control Systems
Physical access is typically managed via a dedicated access control system that combines software, hardware, and locking mechanisms. For example:
- Software and hardware integrated with electronic door locks
- A central database defining which users have access to which areas (rooms, equipment, vaults, gates, etc.)
- Rules that control when and where different credentials will unlock doors and other entry points
Over time, security has moved away from traditional keys and even basic access cards and tags toward network-based, cloud-managed solutions.
Modern systems:
- Are managed via a network or in the cloud
- Allow you to assign different access levels to different doors and zones
- Let you revoke or change access instantly if someone leaves or a credential is lost
- Provide detailed logs and audit trails of who entered, where, and when
By contrast, physical keys, cards, and unmanaged tags can pose risks. If they’re lost or stolen, your premises may be vulnerable until locks are changed or all credentials are replaced – a process that is disruptive and expensive. Digital, network-based access control is safer, more flexible and far more efficient.
Main Components of an Access Control System
A typical physical access control system includes several core components:
- Access point – The entry point where a barrier is required. Common examples include security gates, turnstiles and electronic door locks.
- Personal credentials – These identify the user to the system. Credentials may be cards, tags, mobile credentials, PINs or biometrics, and tell the system who has which level of authorisation.
- Keypads and biometric readers – Users may need to enter a PIN or verify their identity via a fingerprint, facial recognition or retina scan before access is granted.
- Control panel/controller – The device that receives data from the reader, checks it against the rules, and decides whether to unlock the door or deny entry.
- Access control server – Hosted on-premises or in the cloud, this stores user data, access privileges and audit logs, and provides the interface for managing the system.
What Is an IP Security System?
An Internet Protocol (IP) camera is a digital security camera that transmits and receives video footage over an IP network. These cameras are commonly used for surveillance in modern security setups.
Traditional analogue CCTV cameras require local recording devices and dedicated cabling. IP cameras, however, can connect over existing network infrastructure, integrate with other systems and form part of a broader, connected security environment alongside your Access Control Systems.
Traditional vs IP-Based Access Control Systems
When selecting an access control solution, key factors include ease of use, integration capability and scalability.
Traditional (Legacy) Systems – Non-IP / Proprietary
Benefits:
- Dependability – These systems have been used for many years and are known for their reliability.
- Security (in some cases) – Certain proprietary systems may be less exposed to online threats, which some view as an advantage.
Disadvantages:
- Cost – They often require expensive proprietary hardware and multiple control boxes. Because control boxes need to be near the entrances they manage, you may need one per entrance – driving up installation costs.
- Installation requirements – Many require both electrical and system-specific wiring, making installation more complex.
- Limited integration – They’re often self-contained, making it difficult to integrate with other systems (HR, fire panels, CCTV, visitor management, etc.)
By contrast, modern IP and cloud-based systems are typically easier to scale, integrate and manage from a central platform.
What to Look for in an Access Control System
Choosing a system for your organisation is a strategic decision. It usually involves multiple decision-makers, careful risk assessment and more than one quote.
Key considerations include:
- Security level – Does the system provide the level of control and auditability your risk profile requires?
- Features and integrations – Can it integrate with CCTV, time and attendance, visitor management, HR systems or building management systems?
- Ease of use and management – Is the software intuitive? Can access rights be updated quickly and centrally?
- Scalability – Will it handle future growth – more users, more sites, more doors?
- Longevity – Given the cost of hardware, software and installation, you’ll want a system with strong vendor support and a roadmap for future updates and features.
Ultimately, you want an access control solution that fits your security needs and budget and will remain functional, supported, and effective for many years.
