The Core Principles of Access Control Systems

At Falcon Fire & Security, we know that managing who can access your building is just as important as securing it from external threats. Access control systems give you the confidence that only authorised individuals can enter specific areas, protecting your people, property, and sensitive information.

Every effective access control system is built on three core principles:

1. Identification

The system must first recognise who is requesting access. This is usually through a credential such as a card, fob, biometric, or smartphone.

2. Authentication

Next, the system checks that the credential is valid and belongs to the person using it — whether by database verification, a biometric match, or entering a PIN code.

3. Authorisation

Finally, the system decides whether to grant access. Authorisation rules are tailored to your needs, for example, allowing only staff into the office, managers into secure storage areas, or contractors at specific times of day.

By combining these principles, access control provides a reliable, flexible, and auditable way to protect your business.

Types of Access Control Credentials

At Falcon, we design systems to suit your environment and security requirements. Common credential options include:

• Key cards & fobs – Affordable and straightforward, often using RFID or proximity technology.

• PIN codes – Convenient but best used in combination with other credentials for added security.

• Biometrics – Fingerprint or facial recognition systems offer high security and remove the risk of lost cards or codes.

• Mobile credentials – Smartphones can be used as secure keys, combining convenience with strong security.

• Multi-factor authentication – For higher-risk sites, we can layer two or more methods (e.g., card + PIN) for enhanced protection.

On-Premises vs Cloud-Based Systems

One of the first decisions is whether your system should be managed on-site or in the cloud. Falcon offers both, depending on your requirements:

On-Premises Systems

  • Often chosen for sites with strict compliance needs.

  • Requires IT resources for maintenance, updates, and backups.

Cloud-Based Systems

Modern systems hosted securely online, with management via web portal or mobile app.

• Benefits:

  • Remote access from anywhere, perfect for multi-site businesses.

  • Automatic updates with minimal IT involvement.
