Face recognition access control system mainly collects face information through camera. By comparing the huge face template in the background, it can be determined that the residents of the community or floor can pass freely. In this way, even if you forget the magnetic card, fingerprint deformation and password when you go out, you won't be stopped to "brush your face" in and out at the door of the community, which is safe and healthy.

Face recognition technology is used as the "key" of access control system in enterprise parks, government buildings and other places. By comparing the captured face with the pre input face database, the opening degree of the building access control system is controlled through the special "card" of the face, and the access control conditions in different areas, different access points and different time periods are judged. It is mainly face recognition control equipment. On the basis of face recognition, combined with IC card, fingerprint and other methods for joint verification, the security is further strengthened and guaranteed.

One of the representative products of face recognition access control is face door. Face gate is a product that realizes the functions of personnel management, personnel storage, comparison and recording through face recognition system. The identity consistency of entry-exit personnel is checked by importing personnel photos into the database or brushing their faces on the site in advance, and the access records are queried and exported.

一、 Face recognition access control function
Common face access control applications mainly have the following functions:

1. Internal and external personnel diversion management and VIP visitor experience upgrading

By inputting personnel information into the database, internal personnel can directly brush their faces to enter and exit the gate, and external visitors can enter by simply registering information and brushing their faces. Intelligent face recognition greatly saves the time for people to go in and out, and can effectively and orderly manage people's visits. For VIP visitors, the administrator can input pictures in the face database in advance. When visitors visit, they do not need to register. They can directly brush their faces to improve the image of the enterprise.

2. Infrared face recognition, security upgrade, high precision
The face gate adopts infrared face recognition technology, which has strong anti-interference ability. It can reduce the influence of external environment and location, such as illumination, accurately extract face attributes for human dynamic comparison, and greatly reduce the recognition error. When the comparison between personnel and database information fails, you cannot enter. This ensures the safety of people entering. Unregistered outsiders and non library staff are not allowed to enter as others, or even "brush their faces" when taking photos.

3. Multi portal data interconnection to realize cross portal management

When there are multiple entrances and exits in the same unit, multiple face entrances and exits can be assembled. Face gateways in different regions have a unified database and terminal management platform, which can realize the data interconnection between face gateways in different regions and the unified management of multiple entrances. For different units, we will also formulate corresponding customized surface gate solutions according to the actual situation.

二、 Face recognition function
The population in the community is concentrated and the access of personnel is complex. Not only relatives and friends, express, but also strangers. Due to the large flow of people and the lack of energy of managers, the entrance and exit management is not ideal. In addition, the problems such as magnetic card loss, password leakage and fingerprint theft have not been effectively solved. Many lawless elements took the opportunity to sneak in, resulting in frequent community security incidents.

Face recognition access control system realizes cross authentication by combining face recognition, face comparison, Internet of things and other technologies to help community managers accurately identify users. It is understood that the face recognition access control system can effectively prevent strangers from entering and leaving the community at will, minimize the frequency of community safety accidents and strengthen the construction of community safety system because the face features are intuitive and difficult to copy.

With the rapid development of face recognition technology, the optimization of face recognition access control has been further improved. At present, the recognition rate of face recognition technology is not affected by external factors such as makeup technology, portrait photos, mask models, day and night. It is very difficult for strangers to enter the community in disguise.

Compared with traditional access control systems such as fingerprint and magnetic card, face recognition access control system is more intelligent and convenient in management application. In the past, when community staff changed, they needed to change their fingerprints, magnetic cards and keys in time. After the application of face recognition access control, new users only need to access the face information of the community management office, which can save the cost of community personnel change management.
As the first gateway to the safety of living environment, the importance of access control is self-evident, and the design of access control system has gradually become the focus of the security market. In the era of vigorous development of artificial intelligence technology, face recognition is a new force. With the help of Dongfeng, face recognition access control will be further introduced to the market. At present, face recognition access control system has been applied in finance, security, education, office, building management and other fields.
