What are the disadvantages of installing fingerprint locks on the family s anti theft door?

Real intelligence means convenience, therefore, the choice of fingerprint lock needs to see how many intelligent functions it has, how many fingerprint opening capacity, how many groups of password opening capacity, whether there is a voice prompt, whether it can be wireless remote control, whether it can be connected with other smart devices at home or the overall smart home, etc., are all need to be considered, but this part, you need to choose according to your own needs.

There is no such thing as a perfect thing, so while the fingerprint lock is praised on the altar, we also need to objectively understand the disadvantages of the fingerprint lock, and the following is an inventory of the shortcomings of the fingerprint lock and the current problems.

The fingerprint recognition rate is relatively large. There are 1% to 5% of people whose fingerprint recognition rate is relatively low, so it can be opened several times, and many manufacturers are constantly improving this problem. But we have to remember that any product has defects, as long as it can meet the needs of most consumers, it is a good product.

There are many ways to unlock the fingerprint lock, he not only opens it with his fingerprint, but also uses remote control, phone unlocking and SMS unlocking. It is very convenient for our life, the more ways to unlock, it will affect the security factor of our home security door, so we should be cautious when choosing.

The fingerprint lock is a device combined with a motor, and the quality of the lock cylinder, the scientific and rational circuit design will affect the stability of the fingerprint lock. When consumers buy products, it is best to choose fingerprint locks produced by professional manufacturers. Fingerprint locks produced by professional manufacturers generally have a long design and manufacturing experience, and the design is relatively simple and stable, and the practicability is strong.

The number of high-energy-consuming functions, the scientificity of circuit design, the rationality of leakage protection, the number of users and the frequency are all important factors affecting power supply. Manufacturers usually indicate that the battery life of the fingerprint lock can reach one year, in practical application, the life of the fingerprint lock of many manufacturers is less than half a year, and the fingerprint lock does not prompt the user to replace the battery, which often causes the user to be turned away, causing unnecessary trouble. Especially after adding the remote control or IC card function, the power consumption will be very large.

First: Compared with the price of mechanical locks, the price of fingerprint locks is relatively high.

Second: the additional installation cost is higher than that of mechanical locks.

Third: If the master is not installed well, it is easy to fail in a short period of time in the later stage, so pay attention to find a professional master.

Generally, I haven't used fingerprint locks to discuss fingerprint locks, and I'm laughing to death. In a word, since using this thing, it's too convenient. The disadvantage is that it is too convenient, as for security, the lock has always been an anti-gentleman, and the smart lock can be linked, which is safer than ordinary locks.

The advantages are numerous.

The disadvantages are as follows: 1. Purchase cost: a set of locks is more expensive.

2. Cost of use: electricity, and the battery is generally not durable, generally 4 No. 5, and the new battery is generally replaced in less than a year.

3. Easy to destroy: the fingerprint device, keyboard, and screen are damaged.

4. Failure rate: Although it is very low, it is also possible.

5. Lock cylinder safety: can not be locked back and forth. The quality of the lock cylinder varies from manufacturer to manufacturer.

6. The key is generally not around.

7. Misappropriation of keys: generally not. But it's possible.

8. Aging of electronic circuits.

It is possible that the fingerprint will be opened after being stolen.

There will be a lot of fingerprints on it, and there is a possibility that it can be used by people with bad intentions.

Now fingerprints can be imitated everywhere.

If the unlocker is not there, then there is no way to unlock it.

This thing only has a fingerprint to do it.

In this way, it will be embarrassing if a relative comes and is not at home.

If the fingerprint changes, there is a high probability that the door will not be opened.

This thing depends on the use of the person who uses it.

Then people may find a way to crack it.

I don't think this security is good.
