In many old communities, most of them use IC cards to open the door. Because the IC card can be copied and can use the SFC machine to simulate the IC card, there will be no small security risks; and many households sometimes go out. Will forget to bring the access card, can not enter the door after going home, need someone to help open the door. Nowadays, many two-dimensional code access control has sprung up everywhere, and can it be used in the upgrading of old residential areas? This article will tell you how to upgrade the QR code access control.
What is dynamic QR code access control?
In the two-dimensional code access control, the dynamic two-dimensional code and the static two-dimensional code access control, literally understand the difference between the two two-dimensional code access control, the dynamic two-dimensional code access control uses the dynamic two-dimensional code to authorize the door opening The static two-dimensional code access control is to use the static two-dimensional code to authorize the opening of the door. The static two-dimensional code is a product that has been eliminated because it can copy the two-dimensional code in a way that can be photographed or screened. As the name suggests, the dynamic QR code is dynamic. The QR code is different every time. It will change with time. There is no way to copy the QR code by taking pictures or taking screenshots. Dynamic QR code security is more than one and a half points stronger than static two-dimensional code.
How to upgrade the dynamic QR code access control?
In the upgrading of old residential areas, the upgrade cost budget is the biggest problem. If you can replace all the old equipment with the new one, it is definitely the most ho, but sometimes it is impossible to upgrade all the equipment together because of the limited cost budget; even if the equipment is upgraded, the staff will have to pay after the upgrade. The cost of the new system, as well as the time cost of recording the original household data into the new access control system, is not low in manpower and time. If you use the Sebrus dynamic two-dimensional code reader CR02R, there is no such problem. The old community is upgraded, and only the original IC card read head needs to be replaced with the Seberus dynamic two-dimensional code read head. The read head is compatible with the market. Most of the Wiegand protocol access control system, after the replacement, the household's shou machine number ma use tools to convert the card number, and then the residents can use the dynamic QR code to open the door, the original access control system does not need to be replaced, the original information Continue to use, just change the read head to seamlessly upgrade to become an advanced dynamic QR code access control.
Dry Concrete Batching Plant is one special kind of Concrete Mixing Plant , which don't need Concrete Mixer . the aggregate and cements are directly unloaded into concrete mixer truck after weighing . they will be mixed in the concrete mixer truck during the transport . Dry Concrete Batching Plant is popular these years as it it simple and the cost is lower than wet concrete mix plant .
