2. blockchain intelligent door lock system can not be tampered with, difficult to decipher, data can be recovered, and privacy can be protected. At present, blockchain intelligent door lock system has been developed on smart key technology in China.
3. This is not specific. It depends on your site. It was first controlled by 485 cascade. Now it's all network. Due to the distance of network cable, optical fiber is needed for transmission, so centralized design and management is needed. This is the practice of large-scale access control. Small access control can be a separate access control machine, which is directly controlled by locking, and card issuing and authorization are all managed on the access control machine. The family entrance guard is the fingerprint lock series, which is simple, practical and easy to operate.
4. 1. In the intelligent access control system, a sensor card can replace all the door keys, all the access records can be inquired in the computer, and the administrator can manage them
2. The intelligent access control system adopts the advanced split structure control, that is, the card reading part is separated from the control part, and the security performance is improved
3. The intelligent access control system has the function of embedded database management: that is, all the access control system management database data are stored in the device, so as to comprehensively improve the security and reliability of the system data. At the same time, the system data can be mapped to the management PC at any time, so that the data can be backed up or downloaded again.

5. What is the intelligent access control system like
China Science and technology aviation remote access control solutions; Simple understanding is to complete a task according to a signal sent by the door. For example, brush valid card lock to open automatically. Voice prompt is available before opening again
more intelligent, it can record a person entering the door, and the specific time can be located with the accuracy of year, year, day, hour, minute and second
at a higher level, when you swipe the card, you can take photos and record the face photos of the swiper
there are not only access cards, but also passwords, fingerprints, remote control and computer doors. It can also limit the time period for people to enter and leave. For example, only 8:00 in the day to 5:00 in the afternoon, some people have access. Before 8 o'clock and after 5 o'clock in the afternoon, the card cannot be opened
there are two kinds of access control in the community. One is a simple all-in-one machine, which is cheaper than the other. Another is the controller connected to the card reader, which is rainproof. You can also record in and out data.
