Introduction: The common box in the middle of the anti-theft door is the core part of the lock. There are handles and a lock core on the door. There are heaven and earth hooks on the upper and lower right respectively, mainly to prevent violent door removal.
As we all know, the outside pull handle can usually only be used to pull the door, and the inside pull handle can control the first horizontal lock. After the key and the lock core are matched, all the locks can be controlled, including the above-mentioned door lock and heaven and earth hook. The smart lock on the market is actually an article on the box lock. In the past, the shape of the slot on the key was matched with the lock core. After matching, the outside handle can be lifted to open the world hook, and the door can also be opened when the fingerprint code is correct. Nowadays, it is a method of matching digital key, fingerprint, key and other modules, selecting several or all of them together, and replacing the single mechanical key-closure before matching.
Is smart door lock safe?
In fact, security is not the advantage of smart door locks. It is more convenient than traditional advantages.
There is a prerequisite for this. But for the cheap smart locks, simpler fingerprint readers are used. Although this type of fingerprint reader has a higher fault tolerance (for example, the fault tolerance rate is higher if you scratch your fingertips and cracks), if someone else gets your fingerprint, it can be opened by copying. Some expensive smart locks are locked out by mistake several times. So buy a smart door lock, crack the difficulty in accordance with the security to arrange. When you see this, most people may be scared and afraid to use it, but they will not. It is the traditional mechanical lock. Other people can get your key can also copy. There is no theoretical 100% safe door lock. The development of various technologies is the most difficult for normal cracking. As for the thief, don't be fooled by various movies and TV shows. If you can clone your fingerprints and write a program to crack your digital password combination, it is not difficult for him to find a job in the first-tier cities with a monthly salary of tens of thousands.
Therefore, there is basically no thief to unload the door. Most thieves unlock the door and say it is actually simple to make you laugh. Get a big plastic bottle and cut a hole. Go through the door seam and hang it on the inner handle. Open the door directly by pulling the inner handle. Including the way I unlocked myself last time, this method of unlocking the master opened the door. Then, incidentally, if you go out for security, try to put down the world hook. Do not think that the handle outside the door is not moving. You are safe when you go out and lock the door.
If the smart door lock is not charged?
Most of the smart door locks on the market today are powered by dry batteries. The dry batteries are the No. 5 and No. 7 batteries sold in the canteen. Normal use, battery life is generally about a year. If the system detects that the remaining battery power is low, the system will generally push a reminder directly on the phone to allow you to change the battery. If you just happen to catch up with the dead battery, smart door locks usually have a bezel. After opening, you will find the keyhole.
There are also smart door locks that can be used to temporarily power the system using an external power supply (6V battery or Micro USB connection) so that you can open the door first and then change the battery from inside. So you can't enter the house without worrying about the dead lock.
What door can change smart lock? Any request?
The only requirement for security doors is size.
The core structure of this anti-theft lock is actually quite simple. The first is the core of the door lock, insert the lock core after it is safe, and install the front and rear baffles inside and outside. The installation of intelligent door locks is actually replacing the mechanical core with the smart core of the fingerprint, password, and IC card module. Generally, the size of the screws and handles of the original lock should be measured before the purchase to tell the manufacturer.
Recommend you to buy and install yourself, the installation is relatively simple, set the fingerprint password is not inconvenient, the size of the Internet may not be marked in full, it is recommended to communicate with customer service before buying, buy it easy to install.
In addition, because the door lock and the security door are not matched, it is very likely that there will be no connection between the upper and lower world hooks and the door lock core. At this time, whether you are installing yourself or looking for a master installation, be sure to remember to fix or remove the bars. Security is not affected!
