The price of the homepage on the market is different, for example: the same mobile phone products, there are as low as a few hundred yuan for the elderly, there are five or six thousand smart phones, and the same is true for clothes, the price can even be so high that it is unacceptable to the usual. Is it because people buy products with a slightly higher price because they meet a psychological need to pursue grades? It is impossible for anyone to use worthless products, so let's discuss how to choose a cost-effective fingerprint lock.

1、Functional aspects
The functions of fingerprint lock mainly include: fingerprint login, fingerprint deletion, information preservation, use authority management, alarm, emergency unlocking, etc. In addition, many manufacturers have also added some additional functions, such as integrated doorbell, voice prompt, networking, telephone alarm, etc.The high-performance fingerprint lock is also equipped with a human-computer dialogue system such as LCD screen, with a high level of intelligence, with functions such as guiding operation, querying door opening records and built-in parameters, and setting status.

2、Durability

No matter what the product is, we have to think about durability. This has to be from the material of the product, the main materials of the fingerprint lock on the market are aluminum alloy and zinc alloy, and zinc alloy relative to aluminum alloy, the hardness is barely OK, the tensile strength is also large, and the casting performance is average. In terms of material, it is made of 304 stainless steel, which has explosion-proof function and will never rust, and in the choice of battery, there are dry batteries and lithium batteries, and lithium batteries can be recharged in cycles and have stronger stability. And so on, high-quality materials are accompanied by safer and more reliable.

3、Intelligence
For locks, the direct inspection method is to unlock the lock. Most of the unlocking methods of locks on the market are based on fingerprint unlocking, password unlocking, emergency key unlocking, etc., but there are some unique unlocking methods: Mobile phone remote APP control unlocking which enter the password according to the voice prompt of the mobile phone to control the unlocking. This unlocking method is similar to the bank phone system, and the security is higher.
The main function of fingerprint locks is anti-theft, but some fingerprint locks have also developed anti-theft functions. By binding a mobile phone number (you can bind 6 mobile phone numbers), a text message will be automatically sent to the owner when the lock encounters violent damage or lock picking, and the owner can know the situation at home at the front time and give the family a guard at the front time.

4、Convenience
Smart products are a major innovation in science and technology, and most users don't know where to start with how to install, how to use, how to maintain, etc., and they can't know whether the lock is suitable for their home. Then this requires the manufacturer to use a standard international lock body, which can meet the requirements of most locks. What suits you and is easy to install is the king, and if you buy one that is not applicable, no matter how cheap it is, it is a waste. The second is to look at the after-sales service of the product, and choosing a good after-sales service manufacturer is an additional safety guarantee.

5、Lock cylinder
Choose a good lock cylinder, the quality of the mechanical key lock cylinder is directly related to the anti-pry and stability of your door, this part is also very important, no matter how good the fingerprint lock is, it is still inseparable from the lock cylinder part，Under normal circumstances, powerful fingerprint lock manufacturers will choose high-end lock cylinders, so that the product quality will be guaranteed. In particular, consumers can take a look at the number of marbles and the number of shades of the key, and try to choose more products with the number of marbles and the number of shades.The number of marbles of the shallow number of shades is the amount of the key of the mechanical key, the larger the amount of the key, the better the security, the national standard generally requires at least a level A lock or above, a good fingerprint lock manufacturer is generally equipped with a super B level mechanical key, the technical unlocking only takes 3-20 minutes to lock, the Howis fingerprint lock uses a C-level lock cylinder, in terms of anti-theft, the technical unlocking takes more than 3 hours.
