Description

Intelligent Network Security Door

technical field

Background technique

At present, most of the well-known anti-theft doors are formed by enhancing the thickness of the anti-theft door, replacing the steel material of the anti-theft door, increasing the complex structure of the lock body of the switch door, and combining the cat's eye of the door body; , alarm, WIFI, SMS, and camera work together to make different anti-theft door products. The former mainly enhances the anti-theft ability from the material and structure, while the latter combines magnetic cards, combination locks, alarms, etc. to enhance the anti-theft ability. However, for the former, the news once reported the incident of opening the door with tin foil, the door lock can be opened in 3 seconds, and the means of opening the door does not require much professional knowledge. As for the latter, if the encryption rules of the password and door magnetic card are understood by interested people, an unlocking tool can be easily copied. Combined with WIFI, the current WIFI cracking methods emerge in endlessly. You only need to mount a cracking software and a little configuration to achieve cracking. Although another method based on SMS is more difficult to crack, the popularity of pseudo base station technology still leads to the possibility of being cracked. And these several anti-theft methods have a common defect, that is, the door can be opened only by external tools, and anyone has the possibility of opening the door. Even if some full-range cameras are installed, the cameras are 24-hour shooting, and there may be only a small part of useful data in a piece of camera data. In this way, for an ordinary family, there are very few people who are willing to spend time looking at irrelevant data, and the video data volume is large, which needs to be deleted regularly; and a large-capacity hard disk will only increase the cost for ordinary families.
