An office building lobby is one of the most visible and fast-moving entrances in any commercial property. It has to manage a high daily flow of employees and visitors, look elegant enough to match the building’s brand, and keep unauthorized entry out — all at the same time. This case walks through a lobby access project built around brushless swing barrier gates with 8-pair infrared detection and combined face recognition + QR code access.

Project Background

The site was the main lobby of a modern office building. Management needed a passage-control solution that would blend into a clean, contemporary interior while handling peak rush-hour traffic. The key requirements were clear:

• An elegant, minimalist appearance to match the lobby design
• Fast, reliable passage for employees during peak hours
• Two access methods: face recognition and QR code
• Accurate anti-tailgating detection to prevent unauthorized entry
• Low noise and long service life for continuous daily operation

The Solution: Brushless Swing Barrier Gates

The chosen configuration was a set of brushless swing barrier gates installed at the lobby entrance. Swing barriers offer a wide, natural passage that suits office environments, while the brushless motor brings real advantages in a lobby that runs all day: smoother and quieter operation, less mechanical wear, higher energy efficiency and reduced maintenance over the product’s lifetime. The gate’s slim, streamlined cabinet and clean finish deliver exactly the simple, elegant look the client required.

8-Pair Infrared Detection

Each lane was equipped with 8 pairs of infrared sensors. A dense infrared array dramatically improves detection accuracy: it distinguishes a person from a bag or trolley, tracks the direction of movement, and prevents tailgating — a critical safety and security function in an office lobby where staff and visitors pass side by side. This dense sensing also makes the gate faster and safer to walk through, because the doors will not close on a legitimate user mid-passage.

Face Recognition + QR Code Access

The access layer combined face recognition terminals with QR code readers, giving the building two complementary entry methods. Employees can enter hands-free with facial verification, while visitors, contractors and temporary staff use QR codes issued through the visitor management system. The combination keeps the experience convenient for regular users and controlled for guests, without adding a separate gate or manual checkpoint.

Product Configuration Summary

Results and Benefits

• Smooth peak-hour throughput with hands-free facial access
• Flexible visitor management via QR codes
• Reliable anti-tailgating thanks to 8-pair infrared sensing
• Quiet, low-maintenance brushless motors suited to all-day operation
• A clean, modern entrance that complements the building’s brand image

Conclusion

For office building lobbies, the right passage-control solution balances appearance, speed, security and reliability. By combining brushless swing barrier gates, 8-pair infrared detection and face + QR access, this project delivers an entrance that is elegant to look at, effortless to use and secure by design — a practical reference for similar commercial lobby projects.
