One of the most important techniques for fingerprint locks is the fingerprint collector. At present, there are three commonly used fingerprint acquisition devices, optical, capacitive, and ultrasonic. At present, almost all fingerprint locks on the market are optical fingerprint collectors. The acquisition equipment used in this collection method is not easily damaged (such as 1.5CM thick special
glass ), and the capacitive type is generally used in the banking system because the collection equipment is easy. It was destroyed and not suitable for civilian use, and the ultrasonic type is still under development.
Select the fingerprint lock to see the following indicators:
1, manufacturers / brands:
This is the focus of choosing a fingerprint lock. Only when the manufacturer's production quality is guaranteed, can the user's peace of mind be used; only if the manufacturer has after-sales protection, it is possible that someone can solve the problem in time (the product is not bad, we must not think that what we bought is impossible) bad); only manufacturers of quality and after-sale protection available to make the user not to open the
door can not be shut out.
How to choose a manufacturer, each of these manufacturers will say how good they are, and it is possible that everyone said that they are famous brands, etc., I suggest the following:
A, the professional level of the manufacturer: Under normal circumstances, a professional lock company, with lock as the life, he will die if he does not do well, he must do the quality of the lock;
B, the history of the manufacturer: a company has been locked for a decade or two, but still able to survive, and the bigger it is, the more his product will not be bad (we can't say that he is the best, because there may be Better than him). This history refers to the history of doing locks. Don't choose to see the middle of the way and see that the profits are also squeezed into a glass of water. If these people are broken, they can still retire. Just as everyone talks about computers, they think of IBM, think of DELL, and think of Lenovo, because they are professional, large-scale, historical, and accumulated. (Lenovo's mobile phone is not very good, because there are NOKIA, MOTO reasons, he is squeezing in, Lenovo can not sell the business can do business, still do his computer, but NOKIA if it is not good Mobile phone, it’s only about the door);
C, the scale strength of the manufacturer: Everyone said that their quality is good, they are the most professional, who do you believe? Generally, companies with large scale and professional locks can survive for decades. His products are market-tested and can be trusted.
D, the manufacturer's product category: If a lock factory has only one or two locks, and only two or three years have been done, he should have no power. A powerful enterprise often has more than a dozen models or even dozens of fingerprint locks, because the needs of different users may be different. He will have at least a dozen models in the course of ten years. Companies with only a few locks tend to be younger.
E, the after-sales service capability of the manufacturer: If a manufacturer can establish its direct service system in the provincial capital city of the country, his after-sales service capability will not be bad. The after-sales service mentioned here is not his dealer. The dealer is not likely to master the core of the manufacturer. The after-sales service system of the manufacturer plus his dealer service may provide you with the best after-sales service. His dealer may not do it next year, and you may find a manufacturer.
If you can fit the above five points, the strength of this company is generally ok. For the convenience of reference, the user can refer to the history of fingerprint lock: the first fingerprint lock listed in the world is in 2000, the first batch of domestic fingerprint locks is listed in 2001, this reference can know a lock The history of the factory.
