Daozou is the future market for wireless access control

When he was in the access control system, he said: People who understand the access control know that many access control systems are insecure. The access guards don't guard against the villain. Because the electric door is open, you might as well buy a mechanical lock. And our wireless access control system is different from the traditional access control system. The advantages are very obvious.

First of all, from the functional point of view: real-time online networking, Barrier can monitor the state of the door. For example, the door lock status (lock open, lock close, insurance open, and insurance close) you can know in time; there are information on entering and exiting the swipe card (who, when to enter the room, etc.) timely display; alarm information (illegal entry, illegal Credit card, door lock battery low, equipment failure alarm) real-time control. In short, the management center displays real-time operation status of each system, door lock networking information, battery power of door locks, wireless network signal strength of door locks, etc. Barrier gates are used for real-time information logging and alarming and are recorded for future reference.

Secondly, from an aesthetic point of view, we used to do wired access control, and there are many drawbacks to access control. For example, its wiring is cumbersome and its locks are not beautiful enough. Many high-end office buildings and high-end hotels are equipped with magnetic locks and motor locks. Very exclusive. In our wireless access control, there is no wiring at the front end, and all control devices are integrated in the lock, making installation and maintenance very convenient. In particular, we use the smart hotel lock lock body, beautiful appearance and high grade, is the perfect choice for exquisite decoration.

Third, our wireless access control is safe and reliable, and barriers are not afraid of external interference and special conditions such as disconnection of wireless signals. The security level of this system is comparable to the security level of online e-banking. The dynamic key and AES encryption algorithm are used in the communication process. Even if it is the same instruction, the communication packets transmitted in the air are different every time, so that the listener cannot Interception. Barrier Management Center computers can also be used with U shields. When the wireless communication fails, it is equivalent to an unconnected smart hotel lock. The door can still be opened and closed (the same as the opening permission when the internet is connected). The user does not feel the difference between offline and online. The only difference is offline. When the credit card data is temporarily stored in the lock and not immediately transmitted to the center, it is automatically uploaded after the communication resumes normal.

For wireless technology, uniform coverage of signals has always been a problem, but Director Zhao said: Our wireless access control system uses an original patented product—an antenna extension module to solve the low-cost, low-power, uniform wireless network. cover. That is, an ordinary four-conductor cable is placed on the ceiling of the corridors of all floors, and antenna expansion modules are connected in series near the door area (up to 6 gates each), which ensures that the wireless signal strength meets the requirement of reliable communication.

In addition, low power consumption, energy saving and environmental protection are also a value-added effect of wireless access control. With a traditional access control system, the power consumption of a single electric lock (magnetic lock, electric lock, and cathode lock) is about 90 degrees a year, and the power consumption of the gate is also a non-negligible overhead for the user, but we The wireless access control has made breakthroughs, and the lock adopts 4 A 5 batteries for at least 1 year, and the cost of electricity is less than one-tenth of the traditional access control.

The wireless access control system uses the 2.4GHz wireless frequency band and adopts frequency hopping anti-jamming technology. The communication rate is as high as 2Mbps. Since the amount of communication data of the access control system is very small, the data can be transmitted successfully in a very short networked time slot. This type of wireless access control networking has become very stable and reliable.
