With the improvement of people’s living standards, more and more people pay attention to home security. In the early years, smart door locks were still unfamiliar to most people. Now, with the upgrading of smart technology consumption, smart door locks have basically become a necessity for newly renovated families. At the same time, the smart door lock market has also begun to become chaotic, with various brands appearing and uneven quality. For consumers, how to choose a suitable smart door lock has become a tangled matter. In fact, there are still many places to pay attention to from the purchase to the installation of this kind of products. The annual 315 is coming soon. Let’s talk about how to prevent the pit from falling when purchasing smart door locks. After all, this product is a family protection device, and all aspects have noticed that it can save a lot of heart in the future.
The level of intelligent door lock should be C-level.
Whether it is a traditional door lock or a smart door lock, the key to its protection ability lies in the lock core. At present, the classification of lock cores in the market can be described as various, including A-level, B-level and C-level. According to the relevant standards, the lock core of a door lock can be divided into three grades: A/B/C, and the safety of grade C is the best. According to the GA/T 73 "Mechanical Anti-theft Lock" issued by the Ministry of Public Security of the People’s Republic of China, the anti-theft technology of the three grades of lock cores is not less than 1 minute, 5 minutes and 10 minutes respectively. In fact, many thieves can be said to be "experts" in the lock industry. When they see the lock of the C-class lock core, they choose to give up directly, because the long unlocking process greatly increases the possibility of being discovered. Therefore, the door lock products of Class A and Class B lock cores are the "hardest hit areas" for theft. When choosing smart door locks, you need to choose Class C lock cores first.
A-class lock: refers to locks using A-class lock cores, generally including traditional one-word locks, cross locks and crescent locks, and most locks with only one row of marbles in the lock core, which has poor anti-theft performance.
Class B lock: It is a single-row curved lock, which is different from Class A lock in that there is a row of crooked and irregular lines on the key face. There are three main types of lock cores: computer double-row lock core, double-row crescent lock core and double-sided blade lock core.
Class C lock: the key shape is single-sided blade internal milling groove, external milling groove key or double rows+blades, and the lock core type is side column lock core. The marble structure is double-row blades and V-shaped side column locking. This lock core has excellent safety performance and is more difficult to open.
You can’t just ask for low prices when buying smart door locks, and the quality can’t be guaranteed.
Cost-effectiveness has always been the most important place for Chinese people to buy things, so many merchants deliberately use low prices to attract users, but we must know that smart door locks, a family protection device, will definitely be cheated if they blindly seek low prices. There are many ultra-low-priced smart door locks with a price of about 100-400 on the Internet. This kind of products must have cut corners in terms of materials, technology and accessories, which will leave great hidden dangers. At present, the price of mainstream best-selling smart locks is around 1000-2000, which is a normal price.
Not all fingerprint identification is secure.
Nowadays, smart door locks are all equipped with fingerprint recognition, but not all fingerprint recognition can really make you feel at ease, and there are technical differences in fingerprint unlocking. At present, smart locks on the market are mainly divided into optical fingerprint identification and semiconductor biological living fingerprint identification. Compared with optical fingerprint, living fingerprint has higher sensitivity and recognition accuracy. Living fingerprint recognition technology, based on the uniqueness and stability of living fingerprint, adopts real living fingerprint recognition technology, which can recognize dermal fingerprint of skin, and can identify skin temperature and humidity, ensuring that it is an advanced technology that can only be recognized by living body. Its most important advantage is to avoid the security technical problems of copying fingerprints and getting rid of dry fingerprints. It can solve the problem that fingerprints of the elderly and children are difficult to identify, and more importantly, it can effectively eliminate false fingerprints and better protect security.
Facial recognition of smart door locks is not safe enough at present.
At present, many manufacturers have added the "face recognition" unlocking function to smart door locks to attract users. This way looks very high-end, but in fact, in the current smart door locks, this "face recognition" unlocking function is not safe. It has been proved by experiments by reporters that the identification can be completed and the door can be opened with photos. Nowadays, the facial recognition function in the smart door lock is far from the smart phone in terms of the number, density, angle and processing speed of the feature points in face unlocking scanning, and the safety and reliability cannot be guaranteed. Therefore, the smart lock with facial recognition function is not necessarily safe, and it is better to be cautious before the relevant technology is perfected. At present, no big brands on the market have launched products with facial recognition function.
Electromagnetic protection performance must be considered.
Previously, there were many news reports that the "black box" cracked the smart lock. According to professionals, the black box used a transformer to boost the voltage to form a strong electromagnetic pulse, which interfered with the capacitor components of the smart lock and made the lock run automatically to crack. In order to ensure family safety more comprehensively, it is obviously not enough to consider only the security level of the lock core. At present, some smart lock brands on the market have specially designed electromagnetic protection for this situation, which can greatly reduce the electromagnetic radiation impact of smart locks and avoid the "little black box" attack. At present, many manufacturers have joined the anti-"black box" function and anti-trial-and-error self-locking design, which can prevent Tesla coil attacks, and can automatically alarm and lock after five attempts to unlock the wrong lock, effectively warning the lock, and comprehensively improving the security level.
