In 2013, when the iPhone5s was equipped with fingerprint recognition, it was amazing. When the iOS8 was released in 2015, Apple's HomeKet smart home software project was born. At that time, there was speculation in China. If fingerprint recognition technology can be applied to the smart home lock on the smart home hub, it may play an important role. Technology is the core, and intelligence is the trend. From the perspective of the technical reserves of smart home waves at home and abroad, the dream of family door locks away from intelligence and fingerprints has become a reality.
Traditional door locks are in vain, technical ideas or outlets
What kind of security door can achieve the anti-theft effect? An industry insider who has been engaged in security door distribution for many years, the two basic components of anti-theft door anti-theft are the door body and anti-theft lock. In terms of anti-theft performance, the thickness of qualified anti-theft security door should generally be more than 20 mm. The door body layer should be covered with reinforced steel, and the filler should be filled with filler to make the front and rear panels of the door body organically connected together to enhance The overall strength of the door.
Even so, the thickness of the steel plate is still not the focus of the security door. Because the road is one foot high and one foot high, the mechanical security door lock can not stop the cat's eye to break the door, the wire shackle and other "smart" with the times continue to improve. This is the case, the accident of the security door being smashed is still repeated.
What is more noteworthy is that the security door is not not opened, but is not opened for a certain period of time. The national standard stipulates that the anti-theft time of the Class A security door is not less than 30 minutes, the anti-theft time of the Class B security door is not less than 15 minutes, the anti-theft time of the Class A security door is not less than 10 minutes, and the anti-theft time of the D-class security door is not less than 6 minutes.
In this case, the traditional mechanical door lock seems to have encountered a crisis of life and death. With the further development of the smart tide, the intelligence and convenience of home is already the mainstream of life. Intelligent buildings, smart homes, intelligent transportation, etc. are gradually infiltrating into people's lives. Intelligent door locks are almost certain things that can be determined. .
Three different solutions, forward-looking and conservative
Driven by the tide of intelligence, domestic and foreign markets have been thinking about the new way out. Smart door locks based on network and Bluetooth, fingerprint door locks based on fingerprint recognition and even door locks for face recognition and iris recognition have become the choice. Among these three solutions, the smart door lock based on network and Bluetooth is relatively conservative, while the scheme of fingerprint, face and iris is relatively radical. These three solutions can't talk about which one is stronger. In fact, each manufacturer has its own concerns on the technical and realistic levels, and all have strong rationality.
1, based on WIFI, GSM, Bluetooth network
At present, smart door locks based on WIFI, GSM network or Bluetooth are the mainstream choices at home and abroad. This is also the most basic solution for smart door locks.
Yale Yale Electronic Lock, born in the United States, released a residential door lock called Yale Lock. Based on a data network, this door lock supports both iOS and Android phone systems and works with smart watches. When the user opens the door, there is no need to need a mechanical key like a traditional door lock. Just put the phone close to the door lock. If the user forgets to carry the phone or the phone happens to be out of power, the door lock is also equipped with a touch screen, and the user can unlock according to the previously set 4-8 digit Arabic password. The Bluetooth smart door lock is priced at $225 (about 1428 yuan).
However, some domestic smart door locks are more safety-oriented, so they are relatively conservative. In order to prevent the mobile phone from being stolen or hacked, these door lock options still need traditional key unlocking, but the key has a smart chip, and each time the door is opened, the user will be reminded by WeChat or SMS. Similar to Yale Lock, a domestic solution also uses the GSM data network, because the GSM data network can take the encrypted route, which is more secure than WIFI and other solutions. In order to ensure security, the program also has an independent back-end and cloud, which can be connected with the mobile phone, helping users to timely receive and check the information of family members entering and leaving the door through the mobile phone, and has remote alarm.
The idea of ​​a number of products owned by American door lock manufacturer August is even more conservative. In order to ensure absolute security, August's door locks don't even go through the GSM network, but instead unlock the phone directly via a Bluetooth connection. According to August's solution, users can create an account using iOS or Android applications, and pair with August via Bluetooth to automatically lock or unlock the door. Since there is no WIFI standard, there is no need to connect to the Internet, and Internet attacks and cracks are avoided.
