Speed Gate Turnstiles are a form of turnstile designed to allow users to enter faster than traditional turnstiles or swing gates. They integrate with access control services and their response speed is generally much faster than other gates.
Compared to the traditional tripod turnstiles that you’re probably used to seeing at stations and stadiums, Speed Gate Turnstiles are new technology. They’ve recently risen in popularity and are set to be the number-one entry solution for years to come. Many commercial buildings, schools, healthcare facilities, transportation hubs and offices have already adopted Speed Gate Turnstiles.

Speed gate turnstiles are an integral part of modern access control systems, combining advanced technology with robust design to ensure secure and efficient entry and exit. Here’s an expanded step-by-step breakdown of how these sophisticated systems operate:

Authentication
● Credential Presentation: Users initiate the process by presenting a credential at the reader. This credential can be an ID card with an embedded RFID chip, a biometric identifier like a fingerprint or facial recognition, or a digital code such as a QR code displayed on a smartphone.
● Multi-Modal Readers: Many speed gate turnstiles are equipped with multi-modal readers capable of handling different types of credentials, ensuring flexibility and future-proofing the system.

Access Decision
● Valid Credential: If the presented credential is valid, the system sends a signal to the turnstile mechanism to open the barriers. This can involve sliding, swinging, or retracting glass or metal barriers, depending on the model of the speed gate turnstile.

● Invalid Credential: If the credential is not recognized or is invalid, the system denies access. This usually triggers an alert, which can be visual (e.g., red light indicator) and/or auditory (e.g., a buzzer sound), notifying both the user and security personnel of the unauthorized access attempt.

Passage Monitoring
● Sensor Arrays: Speed gate turnstiles are equipped with a series of sensors—optical, infrared, or laser—that continuously monitor the passage area. These sensors detect the presence, movement, and direction of individuals.

● Anti-Tailgating: To prevent tailgating (where one person attempts to follow another through the gate without proper authorization), the sensors ensure that only one person passes per valid credential. If an attempt is made to tailgate, the system can trigger an alert and prevent the barriers from closing until the area is clear.

Closing
● Automatic Closure: After the authorized individual has passed through, the sensors detect the clearance, and the barriers close automatically. This is done quickly and securely to prepare the turnstile for the next user.
● Smooth Operation: The barriers are designed to operate smoothly and quietly, minimizing wear and tear and providing a seamless user experience.

The panels or other mechanical barriers or obstructions are mounted on either side of a channel or lane through which persons have to pass and are mechanically moved, typically pivoting about a vertical axis, to allow persons to pass through a channel from one area to another. It thus performs the function of a turnstile. Often this is facilitated by the presentation of a credential or token such as a smart card, fingerprint, or similar which must be presented to a suitable reader and which, once the user’s credentials have been authorized, either causes the/or each panel to open or releases a break /lock which enables the user to pass through. The electric turnstile may allow movement in either direction (ie for entry or exit (egress)) and passage in both or just one of the directions may require a credential or token authorized entry. Sometimes the operation in either direction may be triggered by a mechanical switch or other means.

Sometimes there is no need for the use of a credential on exit. instead, a sensor or sensors detect the presence of a person wishing to exist and the barrier opens automatically and subsequently recloses. Sometimes free exit is provided utilizing a directional brake which enables a user to pass through in the exit direction but not to pass through in the entry direction unless authorised.

In a situation where authorization is normally required for the exit there is sometimes a requirement that in an emergency egress situation, it must be possible to push the panel away (ie in the direction allowing movement In the exit direction, in order to escape an area quickly. It is possible also to employ directional brakes, clutches, and so on. It is also possible to provide a ‘crash bar’ (crash) type switch (such as the “push for exit” bars seen on emergency exit doors) such that an exiting person could operate it to facilitate exit without the use of a token in an emergency.

The infrared transmitters are fixed on one side of the passageway and the sensors on the other. These infrared transmitters transmit beams which are sensed by the sensors such that a breaking of the beams indicates that something or someone is passing through. They may also be used to stop tailgating and only allow one person at a time through. The apparatus may also be provided with respective card readers which may read an authorization card such as a smart card by the user, and determine whether the user is entitled to enter or exit. Instead of a card reader other suitable authorization means may be provided, either additionally or alternatively, such as retina sensors, fingerprint sensors, or other types of authorization means.
