Face recognition access control? Security turnstiles manufacturers – Mairs makes a brief introduction about the Face recognition access control system.

Demand analysis of face recognition

As living standards continue to improve, people need a safer living environment. The important role of access control systems in safe living environments has been paid more and more attention. At present, the domestic access control system is mainly card equipment, fingerprint equipment, or password setting. These recognition methods require the close operation of personnel, which is extremely inconvenient when the user’s hands are occupied, At the same time, it also brings the hidden danger and high cost of losing, forgetting, copying, and stealing the card or password.

And fingerprint identification, by the online fingerprint set, cracked the “password”, more people feel panic. How to realize the security, intelligence, and convenience of the access control system of the community has become the most expected thing of all citizens. At this time, the appearance of the face recognition access control system really solves the management of the residents’ entering, leaving, and visiting guests, and at the same time, it also forms effective high-security management for the security of the community and buildings.

Advantages of face recognition technology

Face recognition is a kind of biometric technology based on human face feature information. Its uniqueness and good characteristics are not easy to copy provide the necessary premise for identity identification. Face recognition access control system combines face recognition technology with the access control system and uses face recognition as the key to access control. At the same time, the face recognition access control system does not need any media to open the door, and saves a lot of costs, such as personnel changes do not need to replace the door lock, key, IC card, only need to re-register the face;

In the community access control gate application, Because of the simple, safe, convenient, and intelligent operation, and the indoor and outdoor features, the face recognition access control system has many advantages. In recent years, face recognition technology has been widely used in public security, customs, finance, military, airport, enterprises, and other fields.

Some experts further pointed out that the era of comprehensive application of face recognition has come, and it will become an important technology to facilitate people’s daily life. Face recognition technology is widely used in the identity recognition system of the access control system, which will greatly improve the security and reliability of the access control system.

Main features of face recognition


Everyone has a face and can not be copied, copied, so the security is higher.

Good nature

Face recognition technology uses the same biological features as humans (and even other organisms) for individual recognition. Other biological features such as fingerprints and iris do not have this feature.

Simple and convenient

No need to carry the card, recognition speed, simple and convenient operation, to avoid the loss, forget to bring the identification card trouble.


No contact with equipment, no fear of virus contact infection, both sanitary and safe.

Recognition speed, high precision

Due to the development of computer technology, the speed of face recognition can be increased to 0.25 seconds per person under the comparison of a fixed sample base, and the behavior of changing face from different angles, wearing glasses and makeup can also be corrected by adjusting the algorithm of face recognition.

Face recognition has become an important data source in the big data era

Through face recognition and comparison in a large number of regions, using big data analysis, mining, and other technologies, we can fully grasp the behavior trajectory of a specific object or the range of activities of a specific population, without the need for manual intervention in the process, completely handed over to cloud computing, big data system to deal with.

It promotes the application of face recognition technology in various industries and replaces socialized behavior. Therefore, if face recognition technology is widely used in the identity recognition system of an access control system, it will greatly improve the security and reliability of the access control system, reduce the possibility of entering a certain place for criminal activities through identity impersonation, and greatly reduce the existing and potential technical loopholes, hidden dangers and risks in the access control system.

Application scenarios:

With the rapid development of science and technology, our living environment has also changed, and living standards are constantly improving. As the so-called technology changes life, the advent of face recognition is one of them. Subsequently, face recognition gates have also entered various fields. Today’s airport can “brush face” customs clearance, a subway station has begun to “brush face” ticket, office buildings with “brush face” attendance, community “brush face” into the door, and so on. Face recognition not only brings convenience to human beings but also ensures the safety of passing personnel.

Nowadays, a face recognition gate is used instead of a manual to verify a real-name system in many fields, which can realize efficient, convenient, and accurate management of entrance and exit and reduce the cost of manual management. Using the face recognition gate, we can deploy from the front-end camera, connect the collected data with the public security system, help to carry out the investigation work, prevent and the crackdown on criminal behavior, strengthen the safety of public places and improve the efficiency of public security personnel.

  1. At the airport, railway station, customs, and other public transport occasions face recognition and real name verification of ID cards are combined to replace manual inspection with passengers’ self-service security inspection or ticket verification. Moreover, the recognition speed is very fast, which improves the convenience of passengers’ travel.
  2. Office building installed face recognition gate can achieve intelligent office, users can bid farewell to the traditional way of swiping cards, only need to recognize the face can enter and exit. This not only strengthens the management and service of office buildings but also improves the user experience. At the same time, enterprises and properties can also use the data collected through the gate to optimize the management system solutions.
  3. The application of a face recognition gate in a residential area, it makes security means more scientific and technological. It replaces the role of the security guard, and the identification is more accurate and has no omission than the security guard. It can create a convenient passage for the residents of the community and prevent the illegal entry of foreign personnel. When the residents are carrying large bags and small bags, it is not convenient to find their cards, forget to bring them, or lose their door cards. They can enter the door with their faces exposed, It is very convenient and safe for the residents.
  4. Face recognition is applied to the construction site system. The system uses face recognition technology to realize face brushing in and out of the construction site, and multiple people pass at the same time. It has the advantages of fast recognition speed, high recognition rate, large face capacity, convenience, and fast. At the same time, it also avoids defects such as workers’ forgetting or losing cards, and others’ card swiping.

Working principle of tripod turnstile:

Many users of the tripod turnstile gate will ask what is the working principle of the tripod turnstile gate?

What does the tripod turnstile gate use to control the flow of people in and out management, First of all, let us understand the classification of the tripod turnstile gate and the main core components?

Tripod turnstile gate classification: the movement control mode is divided into mechanical, semi-automatic, automatic types.

Mechanical: as the name implies, there is no electric part, pure mechanical operation principle, good safety, long service life, easy to repair and after-sale; shortcomings: can not connect peripheral equipment, small scope of use;

Semi-automatic: electric control part, can be connected to other peripherals, simple structure, easy to maintain, long service life, less after-sale problems; shortcomings are power on the need for manual pole; after swiping cards, the need for manpower to promote the gate passage;

Full automatic type: and the semi-automatic difference is power on, can be their own detection and pole, swipe card after the gate can be automatically popped open, the passage can easily pass the machine; shortcomings: complex mechanism, difficult after-sale, short working life;

The working principle of automatic tripod turnstile gate is as follows:

1. Mechanism base is supported by 1.5 mm square triangle support: this part is one of the main forces of the core, the strength requirement is very high; many of the peers are fixed with an iron sheet.

2. Mechanism is mainly composed of two 24V, 15W square electromagnets (opening and closing), No electricity, After receiving the opening signal, Exciting a 24- V voltage, Hold a voltage of 12 V on lock, Do not supply electricity after passage and one 12 V, 3W round electromagnet, A stroke switch and a hydraulic damper to reduce impact and noise, Noise 70 dB (greater than 30 dB less than 50 dB), turntable and brake rod composition;

3. Working principle of an electromagnet: when the coil is 24 V weak, it becomes an artificial electromagnet, the lock arm of the adsorption gate is unlocked, when the coil is cut off, the lock arm is reset and the tooth cam is stuck.

Regular state adjustment

Manual adjustment and electronic control adjustment, manual adjustment is to adjust the solenoid tail screw; electronic control adjustment has been electrified to the electromagnet.

The structure is simple, symmetrical, intuitive, easy to maintain and maintain;

The counter is counted accurately by the stroke switch. When the brake rod rotates to 30 degrees, the pedestrian completes almost one traffic action, the stroke switch is closed, the gate self-locking, so as to prevent the tail from following;

When adjusting the damper, the red point stays at the value of 5, the strength and speed of the brake rod reset are the best, the greater the value on the damper, the greater the strength of the damper, the slower the speed of rotation;

Mechanism 3 million operations without fault;

Speed:30~40 people per minute.
