Core Functional Features of Turnstile Access Control Systems

Turnstile access control systems serve as the core equipment for intelligent entrance and exit management. Integrating functions such as identity verification, passage control, and data management, they are widely deployed in various settings—including office buildings, corporate campuses, transportation hubs, and construction sites. The core functional features can be broadly categorized into four main groups: Basic Control Functions, Intelligent Identification Functions, Security and Protection Functions, and Management & Maintenance Functions:

1. Basic Passage Control Functions

a) Precise Flow Control and Anti-Tailgating

All ZOJE turnstiles are designed to enforce a "one person, one pass" policy. Utilizing technologies such as infrared sensing and pressure detection, the turnstiles can detect instances of tailgating; should any anomaly be detected, the passage automatically closes, and an alarm is triggered. Passage direction can be configured according to the specific scenario (either unidirectional or bidirectional)—for instance, setting exits at transportation hubs to unidirectional flow, or configuring office buildings for bidirectional flow during peak commuting hours.

b) Fast Opening/Closing and Efficient Throughput

Equipped with a servo motor drive system, the turnstiles open rapidly—within 0.2 to 0.5 seconds—upon successful identity verification. This enables a throughput efficiency of 30 to 40 people per minute, effectively meeting the demands of high-traffic environments such as office buildings during morning rush hours or corporate campuses during commute times. The system also supports automatic opening in the event of a power failure, ensuring the rapid evacuation of personnel during emergencies—such as fires or blackouts—and thereby complying with fire safety regulations.

2. Intelligent Identity Identification Functions

a) Card-based Identification: Supports various card types—including IC cards, ID cards, and CPU cards—making it ideal for the daily passage of internal employees. Cards can be linked to specific personnel profiles, thereby facilitating streamlined access permission management.

b) Biometric Identification: Integrates technologies such as facial recognition, fingerprint scanning, and palm vein recognition. This method eliminates the need for users to carry physical credentials, offers high recognition accuracy, and effectively prevents issues such as "buddy punching" (clocking in on behalf of others) or the unauthorized use of access cards. It is particularly well-suited for environments with stringent security requirements, such as government agencies and financial institutions.

c) QR Code / ID Card Identification: Supports the scanning of dynamic QR codes and the reading of national ID cards. This is an ideal solution for visitors or temporary personnel, allowing for access authorization simply by scanning a code or swiping an ID card, without the need to issue additional physical access cards.

d) Contactless Passage: When paired with technologies such as Bluetooth, NFC, or (for vehicle-specific turnstiles) license plate recognition, the system enables rapid, "frictionless" passage for both pedestrians and vehicles, thereby significantly enhancing the overall user experience.

e) Hierarchical Access Control: Granular access permissions can be configured based on user type, time periods, and specific lane locations. For instance: employees may be restricted to accessing office area lanes, while management personnel are granted access to VIP lanes; visitors may be limited to using designated entrances and exits only during business hours (9:00 AM – 6:00 PM) on weekdays; and temporary construction personnel may be granted access solely to the construction site's main gate.

3. Safety and Protection Features

a) Multiple Anti-Pinch Safeguards

The turnstile wing gates and swing turnstiles are equipped with infrared beam sensors and mechanical anti-pinch mechanisms. When a person or object is detected within the lane, the gates automatically halt their closing motion and reverse direction to open, thereby preventing injury to individuals or damage to property. This feature is particularly well-suited for environments frequented by the elderly and children, such as shopping malls and schools.

b) Anti-Collision and Emergency Response

All turnstile models are constructed from high-strength stainless steel and feature an anti-collision alarm system. In the event of a forceful external impact, the turnstile locks down, triggers an audible and visual alarm, and simultaneously pushes an alert regarding the anomaly to the management backend. The system also supports remote emergency unlocking, allowing administrators to remotely open the lanes via the backend interface or a mobile app to effectively handle emergency situations.

c) Water, Dust, and Interference Resistance

Outdoor turnstile models—such as tripod turnstiles—possess an IP65 (or higher) protection rating, enabling them to withstand harsh environmental conditions such as rain and dust storms. They feature built-in lightning protection and anti-static modules to prevent recognition failures caused by electromagnetic interference.

4. Management and Operations Features

a) Real-time Monitoring and Early Warning

The management backend allows for real-time monitoring of access data for each lane (including headcount, user details, and access timestamps). It supports early warning alerts for anomalous behaviors; for example, if an unauthorized individual attempts to pass, the system automatically captures their facial image and pushes an alarm notification. Additionally, should a turnstile malfunction (e.g., gate jamming or recognition failure), the backend displays a pop-up alert accompanied by the corresponding error code.

b) Data Statistics and Report Generation

The system automatically compiles statistics on employee attendance, visitor access logs, and equipment operational status. It supports the export of daily, weekly, and monthly reports, which can be utilized directly for attendance calculation and visitor management reviews, thereby significantly reducing the workload associated with manual data compilation.

c) Remote Operations and Upgrades

Supports remote firmware upgrades and parameter configuration, eliminating the need for on-site operations and thereby reducing maintenance costs. It enables the batch management of multiple turnstile devices, allowing for the centralized configuration of access rules and recognition modes—making it ideal for distributed environments such as large industrial parks and multi-campus complexes.

d) System Interconnection and Integration

Seamlessly integrates with video surveillance, fire alarm systems, building intercoms, and parking management systems. Upon access verification, it automatically triggers surveillance cameras to capture images, thereby archiving visual records of all entries. In the event of a fire alarm, all access turnstiles automatically open to facilitate emergency evacuation. Furthermore, integration with the parking system enables a unified, end-to-end access experience—allowing users to enter both the campus grounds and the parking garage using facial recognition alone.

5. Features for Adapting to Diverse Scenarios:

a) Office Buildings / Corporate Parks: Focuses on frictionless access via facial recognition, integration with attendance management systems, and visitor appointment scheduling.

b) Construction Sites / Industrial Plants: Emphasizes real-name identity verification, hard hat detection, and integration with government construction management platforms.

c) Stations / Scenic Spots: Prioritizes ticket verification (matching ID cards with tickets), high-throughput rapid access, and anti-climbing security designs.

d) Residential Communities: Centers on facial recognition for residents, QR code-based access authorization for visitors, and dedicated access management for delivery and courier personnel.
