Single live alone also put the key phone lock in the house? Smart door locks to save you
OFweek smart home network news: 25 years old, single living alone. One person goes to work and one person eats. One person watches a movie and one person eats a hot pot. A small but stable home and a small but well-paying salary made me think that I could face the whole world alone, until the cigarette that burned to three quarters.
Sunday night is cold and quiet. The trash can no longer accommodate the packaging of instant noodles. He put on coats, smashed a cigarette and went downstairs. At that time, I didn't know that it would take two minutes to discover "grass! The keys and the phone are in the house!".
Well, this forced me to not fit. All in all, it was to go downstairs to throw garbage and find myself locked out. Finally knocked on the neighbor's door, borrowed the mobile phone to call the master locker, and stayed in the corridor for more than an hour.
So how do you solve the problem of locking yourself out? Today's child's smart lock with everyone.
How smart is the lock?
Before we talk about this, we must first talk about the general structure of the security door at home.
As shown in the figure above, the common security door is jammed. The middle block is the core part of the lock. There are handles and lock cores. There are heaven and earth hooks on the upper and lower right respectively. (Speaking of people is a few high-strength steel bars, called the world up and down, as for the right side is also called collectively called Tiandi hook small series It is not very understandable. It is mainly to prevent violent demolition.
As we all know, the outer handle can usually only be used to pull the door, while the inner 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 groove on the key was matched with the lock core, and the door could be opened after matching. Today, it is a method of matching WiFi, Bluetooth, NFC, digital passwords, fingerprints, keys, etc., by selecting several or all of them to be packaged together and replacing a single key lock.
Most of them like WiFi and Bluetooth are unlocked through the matching of mobile phone apps. Digital passwords and fingerprints can generally be managed via mobile phone settings.
IC card and NFC are usually opened by a chip card. For example, the access control card for your work is IC technology. The NFC is an advanced version of the IC. With the development of the mobile phone industry, many smart phones now have the NFC function. It is also possible to use this method to swipe the mobile phone. In addition, smart home locks are generally equipped with reading and writing functions. In other words, if your work card is not encrypted, then using your own door lock setting can make the work card become the home key at the same time.
Is smart door lock safe?
In fact, security is not the advantage of smart door locks. It is more convenient than traditional advantages. Of course, there is a prerequisite for this.
For example, WiFi, Bluetooth and other mobile App communication. Nowadays, many people's home routers do not know how to change the default password. Any computer student who finds a good university course can steal your key by exchanging data.
The same is true for NFC. For example, if your access card is placed on an office table, he can find an Android phone that supports NFC and ROOT can perfectly duplicate your “keyâ€.
Fingerprints are slightly better. However, for a cheap door lock, simpler recognizers are used. Although this kind of recognizer has a higher fault-tolerance rate (for example, the fault-tolerance rate is higher, for example, if you scratch your fingertips, but it can also be identified), but if someone else gets your fingerprint, it can be opened under copying. Some of the more expensive biometric fingerprinting chips used today are slightly more convenient than the previous ones.
The digital combination unlocks the same difficulty as before the iPhone 5 was cracked. And the lock is not like a cell phone. It locks for a while after a few mistakes. It's not hard at all to try again at a high speed with a computer.
So buy a smart door lock, crack the difficulty in accordance with the security, it should be fingerprint> mobile app> digital combination> NFC.
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 be copied. 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, view information through a router, write a program to crack your digital password combination, then 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 violent burglar that unlocks the door. Most thieves unlock the door, and 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. It took me 100!
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 hit 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 it happens to catch up with the dead battery, then the smart lock will usually have a baffle. After opening, will you find the key hole? ? Uh, go back again.
There are also some door locks that can be used to temporarily power the system using an external power supply (9V battery or Micro USB connection) so that you can open the door first and then replace the battery internally. 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 into the door after it is well installed.
The installation of intelligent door locks is actually replacing the mechanical core with a smart core that includes modules such as WIFI. Before the general purchase, measure the parameters under the icon below.
Xiao Bian personally does not recommend that you buy and install yourself. First, the installation is more troublesome. Second, the size of the Internet may not be marked, and it is very likely that you will not be able to buy it.
In addition, because the door lock and the security door are not matched, there is a possibility that the upper and lower hooks and the core of the door lock cannot be connected. At this time, whether you are installing yourself or looking for a master installation, be sure to remember to fix or remove the bars. Basically, security will not be affected, but if one day the following world is hooked, your security door will be scrapped. When the time comes to find someone to remove the door, it may be more than 100 dollars.
