XB-TD503 Double-Door Anti-Tailgating Speed Gate in Real Projects

Fitness Center and Office Building Access Control

We installed the TD503 Double-Door Anti-Tailgating Speed Gate in two different environments: a fitness center entrance and an office building entrance.Although the two projects have different operating conditions, both customers faced a similar challenge:It was not enough to verify who had access. They also needed better control over who actually passed through the entrance.

A conventional pedestrian gate can verify identity through card readers, face recognition, or other access control devices. However, once an authorized user opens the gate, another person may still follow closely behind.For both projects, we therefore used the TD503 with A/B interlocking gates and 24 pairs of infrared sensors to provide an additional layer of pedestrian passage control.

Application 1: Fitness Center Membership Entrance

The first installation is at a fitness center.This type of facility usually has a high volume of members entering and leaving, especially during evening peak hours.

For the operator, one practical challenge was:

      How can authorized members enter smoothly while reducing the possibility of non-members following them inside?

For this project, we integrated the TD503 with the site's face recognition terminals.

• After a member completes identity verification, Gate A opens and the user enters the middle detection area.
  
• The infrared sensors then continue monitoring the passage.
  
• If the passage condition is normal, Gate A closes and Gate B opens, allowing the member to complete entry.
  
• If abnormal following is detected, the normal second-gate opening process does not continue, and the system can provide a voice warning asking the follower to leave.
  

This means the access control system does more than ask:

“Is this person an authorized member?”

It also helps determine:

“Does the actual passage match this authorization?”

For the fitness center operator, this helps:

• Reduce unauthorized entry by non-members following members
  
• Better protect the membership-based access model
  
• Reduce dependence on staff manually checking every person
  
• Combine face recognition with physical access control
  
• Create a more organized and professional entrance experience
  

During busy periods, we can also adjust the operating mode according to actual pedestrian traffic, helping the customer balance anti-tailgating control with daily access efficiency.

Application 2: Office Building Entrance

The second installation is located at an office building entrance.Compared with the fitness center, this project placed more emphasis on employee access control and the risk of unauthorized visitors entering internal office areas.A common issue with conventional office access control is that an employee completes card or face verification, but another person follows directly behind.The first employee may be fully authorized, but the person following may not be.For this reason, we also selected the TD503 double-door solution for this project.

• During normal operation, Gate A and Gate B are interlocked.
  
• When Gate A is open, Gate B does not open at the same time.
  
• The authorized user first enters the detection area between the two gates. The system then uses its 24 pairs of infrared sensors to check the passage condition before allowing Gate B to open.
  

With this configuration, we helped the customer address several practical problems:

• Reduce the risk of unauthorized persons following employees into the building
  
• Create clearer access control for employees and visitors
  
• Improve control compared with conventional single-gate systems
  
• Reduce the need for security staff to visually monitor every passage
  
• Combine face recognition and anti-tailgating control into one entrance process
  

As shown in the installation, we mounted the face recognition terminals directly at the gate entrance.

After identity verification, the user can continue directly through the controlled passage without additional manual intervention.

From Product Features to Real Project Requirements

For us, these functions are more than product specifications. What matters is how they respond to the key requirements of a real project:

security, stable operation, pedestrian flow, and long-term maintenance.

During project implementation, we configure the number of lanes, passage width, face recognition terminals, authentication methods, and operating modes according to the site entrance dimensions, pedestrian traffic, and the customer's security requirements.

Every project has different site conditions, so we do not simply apply one standard configuration. Instead, we match the equipment and passage logic to the actual operating environment.

Our goal is not simply to install a turnstile system.

Our goal is to make the equipment solve real access management problems for the customer.
