For security reasons, more and more families are choosing to install smart door locks, but this does not mean that all products on the market can meet actual needs. Whether fingerprint recognition is sensitive enough, whether fingerprints in different states can be recognized, whether the lock cylinder is strong enough, and what other features are related to home security… These are core functions that everyone knows little about but are related to security.

This time Jiguojun selected five best-selling smart door locks on the market for testing, namely Wanjia Antencent cloud smart door lock i9Max King Edition (hereinafter referred to as Wanjiaan), Luke Q2 fingerprint lock (hereinafter referred to as Luke), Xiaomi Mijia smart door lock (hereinafter referred to as Mijia), Kaidis fingerprint lock S8 (hereinafter referred to as Kaidis) and Huitailong Huawei Intelligent Ecological Product Smart Fingerprint Door Lock (hereinafter referred to as Huitailong), which one is easy to use and safe? Let’s follow Ji Guojun’s footsteps and take a look!

Who has the most eye-catching appearance

First, compare the five door locks In terms of appearance, although Jiguojun bought all black door locks, the five door locks are different in terms of feel, material workmanship and details. The overall feel of Huitailong and Mijia door locks is relatively smooth, and the door handles are frosted. The handle of Caddis is more rounded, and the overall texture is matte, but the fingerprint unlocking area of ​​Caddis is at the back and there is more in front.There is a display light. This design looks more cumbersome and is not as convenient to use as the other four. The entire Luke is made of brushed metal, while the Wanjiaan panel uses tempered glass.

Fingerprint recognition effect competition

Many people buy smart door locks because they are convenient. They can be opened with fingerprints and there is no need to put keys in their pockets. . However, in actual use, fingerprint unlocking is often blocked by the door lock due to various reasons such as wet hands, dirty hands, or too shallow fingerprints. The speed and accuracy of fingerprint recognition directly affect our understanding of door locks. Use experience. In order to test various fingerprints.What is the speed of recognition and the effect of fingerprint recognition? Jiguojun did some tests:

Recognition speed PK

First test a simple one, first Use clear fingerprints to open five door locks and see how the five door locks perform under normal circumstances and how quickly they open the door.

You can see that in addition to the Mijia door lock, you need to press It takes several times to identify, but the other four door locks can accurately and quickly identify and unlock. From the experience point of view, the door locks of Wanjiaan and Huitailong respond quickly and unlock quickly.

Wet Hand Identification PK

When the hands are dry and wet normally and the fingerprints are clear, most door locks can pass the test. However, in real life, we will always encounter hand problems. The door cannot be opened if the hands are wet due to sweat. In order to test the fingerprint recognition effect of the five door locks when the hands are wet, I washed my hands before opening each door lock.

Test the fingerprint recognition effects of five door locks respectively:

Huitailong

It may be because the fingerprint recognition environment is too difficult, except for Wan Except for Ji\’an\’s ability to accurately identify unlocking, the other four door locks cannot be opened. The Kaidis door lock does not even have an indicator light on, which can ensure smooth operation even when hands are sweaty in summer. Unlocking.

Rough Hand Identification PK

Be aware that your hands are too dry, too rough, and your fingerprints are too shallow. They are all door lock nemesis! Ji Guojun found a dry and rough hand to open five door locks.

The following are the test results:

Mijia

Kadish

Huitailong

Only the door locks of Wanjiaan and Kaidis opened successfully. When the door is opened, the other three door locks are able to identify rough hands very well, which is very friendly to the elderly and people with dry and rough hands.

After testing the unlocking capabilities of five products, Wanjiaan’s fingerprint recognition ability is obviously the best. Whether it is wet or dry hands, it can handle it easily. It is said that the secret to its high fingerprint recognition success rate is that it uses Swedish FPC semiconductor fingerprint chip, equipped with top biometric technology, and has independent identification and fast scanning. Neural network algorithm can identify fingerprints more accurately

Security Capability Competition

For smart door locks, the most important thing is its safety. Various smart locks are designed in terms of security. .The most important thing is the lock cylinder. The security level of the anti-theft lock is divided into level A, level B and level C according to national standards. This level is based on the technology of opening the door.The time used by the lock is defined. Among them, the C-level lock has the most complex structure, is the most difficult to open, and has the highest security. Since the 5 products we tested are all relatively good products on the market, they all use C-level lock cylinders, and they also have anti-black box, anti-peeping, and anti-trailing functions.

The anti-pry lock function of five of the products attracted Mr. Jiguo’s attention. You must know that although the C-class lock cylinder is very safe and the technical lock picking takes a long time, when someone violently picks the lock, no matter how good the lock cylinder is, there is nothing you can do. The anti-pry lock function means that when someone violently picks the lock, you can call the police in time. Inform the owner to prevent bad guys from breaking in.

Three products from Wanjiaan, Luke, and Mijia can trigger anti-pry lock alarms. Among them, Mijia’s is the most sensitive and sounds as soon as it is touched. Caddis and Huitailong No matter how hard you pry the two products, it won\’t help. In addition to the alarm function that everyone has, Wanjiaan\’s products will also send alarm signals to the APP, so that if your home is stolen while you are out, with its camera, you can know in time whether there are any abnormalities in your home, which is convenient Call the police promptly.

Each has its own characteristics

Of course except In addition to the above functions, each company\’s products have their own functions in terms of security. For example, the door locks of Luke and Mijia are part of the Xiaomi ecological chain.The products can be linked to other Xiaomi products for arming. Luke has a child lock function. Huitailong, as a product of Huawei\’s ecological chain, can also be linked to other Huawei products. For example, the access control card of Kaidis is encrypted and cannot be copied. Prevent unauthorized persons from copying access cards, etc.
