Role of Controllers in Access Control Products

Controllers are the core of modern access control systems, managing permissions, handling authentication, and ensuring only authorized access to specific areas. In this blog, we’ll explore how Digital Gardian’s controllers play a vital role in their products like fingerprint terminals, face recognition terminals, smart locks, and more.

What is an access control controller?

An access control controller is a central unit that connects authentication devices (like fingerprint readers, RFID cards, and face recognition terminals) to manage access to secured areas, granting or denying access based on pre-set rules.

Now, let’s look at the role controllers play in the different products offered by Digital Gardian:

How controllers work in Digital Gardian Products:

1. Fingerprint Terminals

1.1. Store authorized fingerprints.

1.2. Compare the scanned fingerprint with the stored data.

1.3. Unlock the door if there’s a match; deny access if not.

1.4. Manage access logs to track entries.

2. Face Recognition Terminals

2.1. Capture and compare the user’s face with stored templates.

2.2. Check lighting and conditions for accuracy.

2.3. Grant access by unlocking the door if matched.

2.4. Manage multi-factor authentication (e.g., face + PIN/card).

3. Smart Locks

3.1. Read RFID card data and check permissions.

3.2. Unlock door if card is authorized.

3.3. Verify fingerprint/PIN and send unlock signal.

3.4. Enable remote access for administrators via apps or software.

4. Card Readers

4.1. Check RFID card ID against stored authorized users.

4.2. Unlock the door if the card is authorized.

4.3. Record access time and user identity for logs.

4.4. Support time-and-attendance tracking and manage multiple entry points.

5. Speed Gates

5.1. Verify identity using authentication devices (fingerprint, card, or face recognition).

5.2. Open the gate once authentication is successful.

5.3. Keep the gate closed until authentication is complete.

5.4. Support anti-tailgating to prevent multiple people from entering at once.

6. Intercom Systems

6.1. Connect the intercom system to the user’s phone or computer.

6.2. Allow remote door/gate unlocking after verifying the visitor’s identity.

6.3. Manage user permission levels, ensuring only authorized personnel can grant access.
