In recent years, with people's gradual attention to safety, efficient management and control of the access of people and things has become the focus of attention, and the access control industry has also achieved unprecedented development. Through the Internetization of the access control system, the intelligent management of personnel entry and exit is realized, which meets the urgent needs of enterprises to reduce costs and increase efficiency. Up to now, QR code access control has become the mainstream of the industry, and the technology and products have become increasingly mature. The following three points will determine whether the performance of the QR code access control system is outstanding:
The scanning and opening speed of the QR code access control system is related to the size of the QR code. The offline QR code (the QR code generated when the mobile phone is disconnected) is relatively large. Compared with the online QR code, the recognition and analysis speed will increase by about 80ms on average.
A new user is added to the management platform, and this information will be sent to the controller and stored in the device. The maximum number of LLID numbers supported by a device is the storage capacity of the device, and it is also necessary to ensure that the QR code with a limited number of times will not be reused.
Under normal circumstances, personnel entry and exit records will be uploaded to the management platform in real time. If the device is offline, disconnected, and communication with the server is not possible, in this case, the logs will be temporarily stored in the device. When the device is online, these stored offline logs will be sent to the server. If the capacity of the QR code access control system is insufficient To store offline logs, it proves that its performance is not perfect.
