Why Are Full-Height Turnstiles the Top Choice for High-Security Access Control?

Full-height turnstiles are the ultimate security devices in intelligent access control systems. With a design that combines complete physical isolation and forced one-way passage, and a gate structure over 2 meters high with multiple anti-impact and anti-climb mechanisms, they are specifically designed for high-security environments such as prisons, detention centers, large factories, border crossings, and construction sites, making them a sturdy protection device that prevents unauthorized entry and personnel escape.

1. Basic structure and materials: "sturdy and durable" is the first principle.

The full-height turnstile design is based entirely on "impact resistance, damage prevention, and wear resistance," and all components are manufactured to industrial-grade standards to ensure long-term stable operation in high-load and high-risk scenarios.

Door frame: Manufactured entirely from 304/306 stainless steel (bulletproof steel plates are used in some high-risk scenarios), with a thickness of 2-3 mm. The turnstile height is 2000-2400 mm (completely preventing climbing) and the width is designed between 500 and 800 mm, depending on the passage requirements (allowing passage of one person in each direction). Some models incorporate a double-door interlocking structure (two doors, one front and one rear; the second can only be opened once the first is completely closed), forming a secure transition booth that prevents unauthorized access or forced entry.

Full-height turnstile(tripod type), three-roller sliding door: The door is made with solid stainless steel rollers (50 to 80 mm in diameter, with the same length as the door height). One-way operation is achieved by rotating the roller axle. Its structure is simple and resistant to violent impacts (such as attempts to force it open or blows with tools, maintaining the mechanical locking mechanism).

Full-height turnstiles(swing type): The turnstile is made of thick tempered glass (12-15 mm) or stainless steel sheet. Its opening and closing mechanism is similar to that of a conventional swing door, but its height spans the entire structure and, when closed, integrates perfectly with the frame, leaving no gaps that would allow access.

Drive and control components: It adopts an industrial-grade geared motor (high torque, resistant to overloads and able to withstand frequent starts and stops) and a mechanical locking mechanism (automatically locks the door when power is cut off to prevent illegal openings), combined with an "anti-violent dismantling sensor" (instantly triggers an alarm when an attempt is made to force the box) and an "infrared beam array" (covers the entire channel and accurately detects the position of the human body).

2. Operating principle: a rigid process of "authorization verification - one-way passage - forced blocking".

The operation of the full-height turnstiles prioritizes safety. By interconnecting the mechanical structure and the electrical control system, it is ensured that each step is rigorously verified and that reverse or illegal passage is not permitted.

Multi-access control verification: Full-height turnstiles are typically equipped with dual/multi-access verification (card swipe + facial/fingerprint recognition + password/IC card + biometric ID). Verification information is simultaneously uploaded to the management system. Personnel can only gain seamless access after authorization from the administrator or the system.

One-way door opening: After authorization, the system only opens the door in the current direction of travel (e.g., entry is only permitted in the entry direction and exit only in the exit direction). The door opening angle is controlled to allow passage at a single point (approximately 30-45°), and the opening time is limited (typically 3 to 5 seconds, after which it closes automatically).

Real-time traffic monitoring: As pedestrians pass through, multiple sets of infrared sensors (covering the height of the door horizontally and the length of the passage vertically) perform real-time monitoring. If it detects that several people are following each other, that someone turns around mid-pass, or that someone is lingering too long, the door will immediately stop closing and trigger an audible and visual alarm. Simultaneously, the system will send alarm information (such as pop-up windows and SMS notifications) to security personnel.

Forced locking after passage: Once pedestrians have completely passed through the passage, the gate resets and immediately locks mechanically (remaining locked even without power). Authorization must be re-verified to open it, ensuring the passage is always in a "controlled closure" state.

3. Features: Designed to meet "essential protection needs" in high-security scenarios.

The full-height turnstile is fully adapted to the basic requirements of "preventing unauthorized entry and exit and preventing violent damage."

Full-height turnstile boasts the highest level of physical protection: the door's total height, exceeding 2 meters, completely prevents climbing or any other unauthorized access. The stainless steel frame and solid door withstand violent impacts from tools such as hammers and crowbars (some models can withstand an impact force exceeding 500 N), and the absence of gaps or handles that could allow climbing completely eliminates the possibility of unauthorized entry.

Rigid one-way passage: Through a mechanical structure design, the door can only be opened in the set direction (e.g., the entrance door only allows entry and the exit door only allows exit) and cannot be pushed in the opposite direction (when the door is pushed in the opposite direction, the mechanical locking mechanism immediately locks and activates an alarm), effectively preventing "entering through the exit" or "escaping through the entrance".

Multiple alarms and connections: It features various alarm mechanisms, including a violent impact alarm, tamper alarm, unauthorized intrusion alarm, forced entry alarm, and unlawful occupancy alarm. In addition to local audible and visual alerts when an alarm is triggered, it can also connect to the security system (for example, by activating the focus of nearby surveillance cameras, connecting the access control system to lock surrounding doors, and sending the alarm's location and real-time video to the security terminal).

High reliability and low maintenance: The main components (motor, locking mechanism, sensor) are all industrial grade, allowing for uninterrupted 24-hour operation (MTBF ≥ 50,000 hours); the equipment features an "automatic fault self-diagnostic" function, which detects the status of the motor, lock, and sensor after ignition, and pinpoints the specific fault location (such as "sensor failure" or "motor overload") via indicator light codes or the background system when a fault occurs, facilitating quick repair.

4. Application Scenarios: Specialized Equipment for High Security and Strict Control

Thanks to their high-security and isolation features, full-height turnstiles are primarily used in scenarios requiring extreme precision in personnel access control. Their use in ordinary civilian environments is infrequent. Some typical examples include:

Judicial and Special Supervision Centers: Entrances and exits of prisons, detention centers, and drug rehabilitation centers, as well as visiting room corridors, using a double-door system with interconnected gates and multiple biometric identification to prevent inmate escapes; staff access corridors in detention centers and shelters to ensure restricted access to the controlled area.

Border and Port Control: Personnel control lanes at land ports and verification exits at border crossings, using triple verification (passport, facial recognition, and fingerprint) to achieve verification by person and document, and prevent illegal entry and exit; Personnel entrances and exits at customs warehouses and free trade zones to ensure control of personnel movement within the supervised area.

Large industrial and energy facilities: Entrances to production areas of petrochemical plants and nuclear power plants (high-risk areas requiring strict personnel control); entrances to coal and metal mine shafts (access is permitted only to licensed miners; unauthorized personnel must be prevented from entering); main control buildings and access corridors to equipment areas at large power plants.

High-security units: Separation corridors between family housing and barracks at military bases; entrances to laboratory buildings at national research institutes; and corridors to production workshops at classified companies. Multiple security lines are implemented using a combination of high-voltage turnstiles, access control systems, and surveillance cameras.
