The most practical smart home items talk about the purchase of fingerprint password lock

After experiencing two consecutive forgotten keys, and finally had to spend hundreds of oceans to help unlock the company's fire, I finally made up my mind to replace the ordinary lock on the security door with a smart fingerprint lock. After using the fingerprint lock for almost half a year, I will talk to you today about some of the experiences of choosing and using the security fingerprint lock.

(Taobao enters "smart door lock" or "fingerprint lock" and other keywords, you can find a large number of goods, the price is from about 1,000 yuan to 5,6 thousand yuan are distributed, find good use in these mixed products And it’s not that easy for you)

First, appearance & function

The first step in buying things is definitely the appearance. I live in an old-fashioned community and the bottom floor. This means that there are a lot of people passing through the door every day. It is a bit worried to install a security lock that looks too exaggerated. So the first thing I thought about at the time was to choose a product that looks as close as possible to a traditional lock.

(The appearance of this fingerprint cipher is very close to the traditional lock, and many guests who come to the house have not found it is actually a fingerprint lock)

Second, we must consider the function. At present, most of the smart door locks on the market are integrated with the fingerprint + password function, and some have the function of magnetic card induction or even APP joint control. Of course, the most basic key opening function will basically be retained. From the perspective of security, fingerprint is the safest and most convenient way to open, and the key is basically only used as the final insurance. Therefore, when determining the function, I don’t have much to say how much the open mode is, but Focus on performance:

1. When examining fingerprint recognition performance, you should first pay attention to whether it has a living body detection function, that is, it can only identify the fingerprint of a living person. Otherwise, if the risk is still quite high, don't think that copying your fingerprint is in the movie. There will be bridge sections. In fact, it is easy to buy a full set of fingerprint copying materials and tutorials in dozens of Taobao flowers. Before the media exposed the real case of fingerprint punching machines in the office by copying their own fingers.

2, followed by the issue of recognition rate, is also my most concerned. Because my palm has a certain peeling problem all the year round (I believe that many people, especially young male friends, have similar distress). Traditional Chinese medicine says that it is mainly "body fever", while Western medicine has no obvious statement. It is generally explained by exposure to specific allergens. The peeling of the palm has a great influence on the success rate of fingerprint recognition. For example, when I use the TouchID of the iPhone, I can only use it when the peeling is not so serious, so that I later gave up this function because of the recognition error again and again. The tip experience is really bad.

The door lock I chose is an identification system with a three-dimensional imaging inspection system of “black and white imaging + color imaging + infrared imaging”. It was found through the use of nearly 3-4 months, except that the fingers are very moist or extremely peeling. In serious cases, the fingerprint recognition system works very reliably, which also makes my default password function almost never used.

3, password function: mainly depends on the length of the supported password (too short to break too long and easy to forget), and support does not support smart password programming (you can enter a long string of numbers, as long as it contains a password can be unlocked) and so on Camouflage" feature.

Second, convenience

In addition to performance, door locks are used every day, and some convenience designs are also considered. For example, the layout of the fingerprint recognition area on the fingerprint lock is more elaborate. The most common one is to place it on the panel of the lock body. The trouble with this layout is that the finger should first touch the recognition head at a certain angle when recognizing, and then move the arm to turn the door handle to open the door. If the position of the recognition head is too high or too low, the angle is not good, and if the recognition needs to stay for a few seconds, this process will cause fatigue. The fingerprint lock I chose is to set the recognition area directly on the hinge of the handle. Using the normal door opening gesture, the thumb fits the lock shaft and can directly realize the fingerprint recognition. The process of unlocking is actually used at home. The elderly also find it very convenient.

The second is the function of password unlocking. As I said before, the community I live in belongs to the old-fashioned community, and the door of the corridor unit will not be locked all the year round. Plus the floor is low, so I am very worried about curious neighbors or naughty children coming to bang the password button, causing the battery to consume too fast.

(I chose this fingerprint lock to classify fingerprints including digital passwords and design different permissions for different family members)

The digital input area of ​​this combination lock features a virtual touch button design. The area is not large, and the background color is black, so it looks like a normal plastic decorative board under normal conditions. The button to start the virtual keyboard is not conspicuous, and it is easy to be ignored, which also reduces the possibility of being mishandled by others.

Secondly, it should be noted that other additional convenience features, such as the classification management of fingerprints, the classification management of digital passwords, and even the ability to query unlocking records, etc., can bring us traditional locks that cannot be provided. Convenience.

●Security

Finally, talk about the security of the lock. This is divided into two aspects: anti-theft performance and insurance performance.

The first is insurance performance. The fingerprint lock is powered by the battery, so there must be a battery drain. And what if the fingerprint fails and the password is forgotten? Therefore, the final insurance method must be reliable. I chose this fingerprint lock in addition to the low battery early warning, the ability to external temporary power supply, also reserved 2 just in case of the insurance key (expected to unlock the master to open the smart door lock is not significant, ten Eighty-nine can only forcefully dismantle the entire door).

Secondly, the anti-theft security of the lock cylinder (lock) itself is a place that many people are more likely to ignore. Before I was optimistic about a foreign brand fingerprint lock, I had a serious quality problem. One of the reasons was the use of plastic locks. The domestic fingerprint locks generally attached importance to the reliability of the lock cylinder. Most of them used integral cast copper to prevent violent unlocking. Anti-theft lock core (individual feeling can not do 100% anti-theft, can only delay the speed of unlocking), whether it is life, reliability or psychological security, may be better.

Finally, there are some fingerprint password locks on the market that support mobile APP control, but I have not chosen that product. Mainly used a lot of so-called smart appliances before, and mobile APP network control in addition to the beginning of the map freshly used a few times, the actual use is actually rarely used, and take into account the lock body standby time (increased WIFI transceiver module must add Power consumption and security, smart locks with reliable fingerprint recognition and password capabilities have been able to meet my needs.

In general, this time changing the fingerprint lock makes people feel more secure, and then worry about forgetting to bring the key, or go halfway on the way to work and think about whether there is a lock on the door. For those who are sick and often lost, the smart door lock is definitely worth a try.
