The prices of products on the market vary greatly. For example, for the same category of mobile phones, there are elderly phones that cost only a few hundred yuan, and smart phones that cost five or six thousand yuan; the same is true for clothes, the price can even be so high that ordinary people cannot accept it. So when people buy products with relatively high prices, is it because they meet the psychological need of pursuing grade? It is quite possible that this is the case! No one would use a completely worthless product, even if the price is high, it is still worth the money. Next, let's discuss how to choose a fingerprint lock with high cost-performance.
1. In terms of functions
The main functions of a fingerprint lock include: fingerprint registration, fingerprint deletion, information storage, usage authority management, alarm, emergency unlocking and so on. In addition, many manufacturers have also added some additional functions, such as integrated doorbell, voice prompt, networking, telephone alarm, etc. High-performance fingerprint locks are also equipped with man-machine dialogue systems such as LCD screens, with a high level of intelligence, featuring functions such as operation guidance, query of access records and built-in parameters, and status setting.
2. Durability
No matter what kind of product it is, we have to consider its durability. This has to be discussed from the material of the product. The main materials of fingerprint locks on the market are aluminum alloy and zinc alloy. Compared with aluminum alloy, zinc alloy has acceptable hardness, higher tensile strength, but average casting performance. Some fingerprint locks use 304 stainless steel as material, which has explosion-proof function and hardly rusts. In terms of battery selection, there are dry batteries and lithium batteries. Lithium batteries can be charged cyclically and have stronger stability. All these high-quality materials bring higher safety and reliability.
3. Intelligence
For any lock, the most direct test is unlocking and locking. Most locks on the market mainly use unlocking methods such as fingerprint unlocking, password unlocking, and emergency key unlocking. However, there are some unique unlocking methods: remote APP control unlocking via mobile phone. You can enter the password according to the voice prompt on the mobile phone to control unlocking. This unlocking method is similar to the bank telephone system and has a high level of safety.
The main function of a fingerprint lock is anti-theft. However, some fingerprint locks have developed additional advanced anti-theft functions. By binding mobile phone numbers (up to 6 mobile phone numbers can be bound), the lock will automatically send a text message to the phone owners when it encounters violent damage or lock picking, so that the owners can know the situation at home immediately and provide protection for their families at the first time.
4. Convenience
Smart products are a major innovation in technology. Most users do not know where to start when it comes to installation, use, maintenance and other issues, let alone judge whether the lock is suitable for their home. This requires manufacturers to use standard international lock bodies, which can meet the requirements of most doors. The right one that is easy to install is the best choice. If you buy an unsuitable one, it is a waste no matter how cheap it is. Furthermore, you should look at the after-sales service of the product. Choosing a manufacturer with good after-sales service means you get an extra layer of safety guarantee.
5. Lock cylinder
Choosing a good lock cylinder is very important. The quality of the mechanical key lock cylinder is directly related to the pry resistance and stability of your door, and this part is also very important. No matter how good the fingerprint lock is, it ultimately cannot do without the lock cylinder. Generally speaking, powerful fingerprint lock manufacturers will choose high-grade lock cylinders, which can guarantee the product quality. What consumers can check intuitively is the number of pins and the number of depth levels of the key. You should try to choose products with more pins and more depth levels. The square of the product of the number of depth levels and the number of pins is the key quantity of this mechanical key. The larger the key quantity, the better the safety. The national standard generally requires at least Grade A locks. Good fingerprint lock manufacturers generally configure super Grade B mechanical keys, which take 3 to 20 minutes for technical unlocking. HolaShun fingerprint lock uses a Grade C lock cylinder. In terms of anti-theft, technical unlocking takes more than 3 hours.
