Mobile Management Access Control System Has Become the Mainstream Battlefield. What Technology Is Mo

In recent years, with the popularity of mobile phone applications, WeChat mobile payment and Alipay payment parking fees have become popular in the car park. Many industries that are not warm before then are also popular. Access control industry is one of them. Nowadays, mobile phones are indispensable to the public and can be said to be a necessity of life. Therefore, mobile phone management access control system must become a mainstream battlefield.

At present, there are four main solutions for mobile phone intelligent access control at the technical level: Bluetooth, NFC, QR code and WiFi. So what technology will win more people's hearts? I. bluetooth access control Bluetooth technology is very mature. It is a wireless technology standard, which can realize short-distance data exchange between fixed equipment, mobile equipment and building personal area network. Bluetooth access control can be connected with the access control at a distance of about 8 meters without the interference of obstructions. The Bluetooth service is called through the app at the mobile phone end, the intelligent hardware is installed at the access control end, and the door lock is controlled after receiving the Bluetooth command. Bluetooth access control has the advantages of high mature technology, low transformation cost and long control distance; Of course, the disadvantages are also obvious, such as the need to turn on the Bluetooth function of the mobile phone, the reading effect will be affected if there are obstructions, and the version is often upgraded. 2. NFC access control technology evolved from non-contact radio frequency identification (RFID), and the implementation of NFC access control first requires a mobile device with NFC function; Secondly, it is also necessary to configure the hardware that can read the virtual credential card from the mobile device with NFC function; Finally, an ecosystem must be developed that includes mobile network operators, trusted service managers, and other operators that provide and manage mobile credential cards.

The advantage of NFC access control is that the setting program is short. Using NFC instead of manual setting will greatly speed up the creation of connection, less than one tenth of a second; Low power consumption, only linked to one machine at a time, with high confidentiality and security. The disadvantage is that there are fewer mobile phones supporting NFC function than those supporting Bluetooth, which is only suitable for specific occasions. III. QR code access control QR code records data symbol information with black-and-white graphics distributed on the plane (two-dimensional direction) according to a certain law. QR code access control uses QR code as the medium and carrier of personnel identification, and the system assigns an encrypted QR code to each user in real time, The user can open the corresponding door lock by scanning the QR code on the access control equipment.

Two dimensional code has more advantages than the previous two. At present, two-dimensional code is widely used, convenient and easy to use, which is conducive to popularization; QR code can well integrate the two functions of access control management and visitor management; Both mobile phone and official account can support most smart phones; APP or public address. Good user experience. Of course, the disadvantages also exist. The QR code is easy to copy and has potential security risks; The transformation cost is high. IV. WiFi access control WiFi is the most widely used wireless network transmission technology today.WiFi is not affected by the hardware chip and operating system. It has fast connection speed, can connect one to many, and can also connect directly to the Internet. It is advanced and forward-looking. Since its release, it has never been replaced, there is no compatibility problem, and it is suitable for all mobile phones. WiFi access control is widely used in intelligent communities. It is usually used together with monitoring to manage access control through app.

WiFi access control has many advantages. For example, using WiFi access control is usually one of the most popular applications, with great compatibility, scalability and rich functions; The communication protocol is a unified standard 802.11n, and all smart phones can be stable and applicable; The background management is convenient and remote door opening can be realized. The disadvantage is that it needs to access the network and the cost of transformation is high; WiFi access control is highly dependent on the network. If the network is disconnected and the network signal transmission is unstable, the application of this function will be directly affected. For the above three, WiFi access control is the best mobile phone management access control system at present.

Tigerwong visual intercom access control, supporting video intercom of mobile devices such as mobile phones and tablets; Support card swiping and password opening, mobile phone Bluetooth, mobile phone number and code scanning; The intercom distance is not limited, the network coverage is enough, and the call content is safe and reliable; Support visitor management, unit building number call and mobile phone number call; Support TCP, IP network, WiFi network and mobile network (3G and 4G); Wiring free, with network, simple construction and convenient transformation; Powerful function, intercom, management anytime, anywhere, cluster, point-to-point. The application of mobile phones in the access control system has been what many access control enterprises are doing at present. With more and more people relying on mobile phones, users' acceptance of mobile phone management access control products is becoming higher and higher. Different mobile phone management methods will cause users to have different degrees of acceptance of door ban management. The waves behind the Yangtze River push the waves ahead.

To stand in this storm, you can't face the surrounding pressure without strong own technology, and you can't get a place in this mainstream battlefield.
