1. Fingerprint lock fingerprint identification is very important: now common are optical fingerprint identification and semiconductor fingerprint identification

Optical: the price is slightly lower, the effect on the dry and cold environment is not good, and there are no holidays. There are hidden dangers of fingerprint and fingerprint residue

Semiconductor: it has poor antistatic ability, some are sensitive to wet fingers, but the speed is faster, and can be more used to low-temperature and boring environment. There are also a variety of semiconductors, which have better and more accurate effects throughout large planar chips, while the experience of sliding small areas is much worse.

2. Fingerprint locks are now basically accompanied by code, card swiping and spare keys. Keys are also very important when selecting. As a household key, it is an insurance. Products without keys should not be selected as far as possible. Especially the high-rise residence! Keys also have a security level. It is safer to select those with level B or above. Considering the different age spans of family members, it is more suitable to select those with card swiping function as far as possible.

3. Product structure is very important. In many mechanical locks, the front and rear plates are connected by two screws. It is very lazy to fix only two screws. Don't do this for fingerprint locks. This product can't be selected. The front and rear panel links need at least three screws to be reliable. The two screws are very simple, loose and distorted, and the panel is simply pried off, It's a very unreasonable plan!

4. Lock body classification: now there are mainly mechanical lock body, semi-automatic lock body, self elastic lock body, electric lock body and no lock body. Most mechanical lock bodies are accompanied by heaven and earth locks. In fact, this effect is not great. This is brought out by the door factory, because these lock points are brought back by holding hands, which can not achieve any essential effect. And most of the lock bodies are mechanical locks. The modified clutch is on the panel, maybe on the front or rear panel, which is not a reasonable practice. The semi-automatic lock body usually has a small motor inside, which is a common practice in the market. When selecting, it depends on the thread end treatment. We must pay attention to the products with tight and regular wire harness. This reflects the product optimization of the manufacturer. The new ones or those without too much experience are often messy, the wire harness is not well wrapped, the skin is simple, and the self elastic lock body is relatively few now, It's not advisable to lock automatically by closing the door and collision. This is simple to hold, and the fault is high. The electric lock body is a fully automatic and useful product, but it requires high skills and can't do much. Now only a few brands have it, which is very convenient. In addition, there is no lock body. In order to save trouble for the device, the so-called exchange does save a lot of things for the master. However, our owners must pay attention to that many manufacturers have different lock body quality, different data and different service life. If they do not change the lock, they will directly bury hidden dangers, and problems may occur in a few months or half a year.

5. The fingerprint lock will consider the power supply problem. The mainstream is to use dry batteries, four or eight. They are generally used for about a year, and some use rechargeable batteries or pull wires. The pull wires are basically unacceptable. Here we talk about lithium batteries. Everyone knows that the cost of good lithium batteries is not low, and the fingerprint lock does not say that there is a strong brand. After all, the development time is only about 10 years, At present, the lithium battery skills are not particularly ideal. It is sensitive to high temperature and low temperature environment, and there are potential safety hazards. Most other lithium batteries set their own specifications, which adds to the problem of after-sales. You will find that in a few years, your lithium batteries are out of stock, can't be bought, and the manufacturers are gone. This is still very difficult. Dry batteries have the same specifications all over the world, And I'm satisfied that I can change it once a year. There's no need to take risks at all, unless I have a new breakthrough in skills and update my power!

6. Some fingerprint locks have apps. This is a selection question. The app is convenient and has a good experience. It can be selected according to your preferences. Others are generally optional and can be added later. There is no problem. However, we should also pay attention to the use rights and security of the app. Some simple apps can open the door without a secret code. There are security problems. Try to choose those that need a secret code. After all, security is still very important.
