Video surveillance system, access control system and anti-theft alarm system are the three pillars of civil security, supporting most of the market share of civil security, and its various types of products have been widely used in all walks of life.

In recent years, people's living standards have been continuously improved, and intelligent life is one of the inevitable trends of social development, and it is also the ideal state that most people want to pursue. In the management of entrances and exits of communities, residences, and office buildings, access control systems play an important role in intelligent management. With huge advantages, scenarios such as mobile phone opening, 2D code opening, remote opening, etc., make our way of passing more intelligent. Below we will briefly introduce the 2D code access control system among the access control systems, and two Dimension code core module.

The 2D code access control system mainly uses the mobile phone to scan the code for entry and exit. It is mainly divided into static and dynamic 2D code modes. In addition, it also provides remote door opening, which provides a fast and convenient way of access and is very popular.

The reason why QR code access control has such good functional advantages is that the main core source is the QR code access control module, so what role does the QR code module play in it?

The existence of the 2D code access control module can meet different living environments in terms of safety and technology, meet different functional management methods, reduce labor costs, and make management more advantageous.

Compared with the traditional access control system, the QR code access control module solution not only meets the requirements of communities, residences, and office buildings, but also ensures more intelligent management and avoids the trouble of carrying or losing access cards.

Compared with the traditional access control system, most community scenarios use the 2D code access control system, which is simpler to maintain and more convenient to operate. Therefore, the 2D code access control has been rapidly popularized. In the process of use, there is no need to invest too much maintenance costs. More and more scene environments are beginning to use such access control systems to bring a safer experience.
