Now is an era of exquisite, fast and quality. Therefore, many household products are more in line with the concept of the new era, such as the emergence of fingerprint lock price. Fingerprint lock has the characteristics of high technology and high security. You don't need to carry the key. As long as you enter the fingerprint quietly at home, the identification function can help you open the door. But how can we buy smart lock in the early stage of home decoration? After all, smart lock is a new thing. It is not so simple to buy a smart lock with excellent quality and rigorous function. Generally, when purchasing fingerprint lock, we should pay attention to the objectives of "universality, security and stability".

I. universality and security of test function

The "test function" here refers to "three opening and two degrees", "three opening" refers to fingerprint unlocking, secret code unlocking and magnetic card unlocking, "two degrees" refers to the response speed and fineness, that is, to test the speed and fineness of these three door opening methods.

Mainly, test the response speed and fineness of fingerprint unlocking. Let the clerk enter your fingerprint first, which is also a step to verify the function of fingerprint lock. When recording fingerprints, investigate the difficulty of the clerk in entering fingerprints. If a fingerprint cannot be recognized repeatedly, it can be judged that the resolution of the fingerprint lock is not high (the higher the resolution, the finer the identification, the faster the response, and the better the security. At present, the industry standard of fingerprint lock resolution is 500dpi). After entering the fingerprint, randomly test the identification and response speed of the fingerprint lock to the correct fingerprint. If it is clicked on, its response speed is fast, otherwise it is slow. The faster the response speed, the higher the resolution, and the better the function of the lock. Similarly, if you can quickly identify true and false fingerprints, then its fineness is good, otherwise it is poor. During the test, it is suggested to try several times. Only a few more tests can identify its advantages and disadvantages.

Secondly, test the magnetic card and secret code to unlock. The test method of magnetic card unlocking and fingerprint unlocking is the same. It is also to test its response speed and fineness. Test the authorized magnetic card and unauthorized magnetic card respectively in the magnetic card area to see the response and identification of the lock to the magnetic card. If the response speed is fast, the function of the lock is good, and vice versa. The secret code door opening is also used to measure the response speed and fineness. The test method is also replaced by the correct and incorrect methods. The faster the response speed is, the higher the skill content is, and the higher the fineness is, the higher the security will be.

II. See the stability of the core insert

To buy a fingerprint lock, in addition to the lock body, the plug-in core is also a very important part. If the plug-in core has excellent quality and reasonable planning, it will not often have problems in the future. Stability is also a key to pay attention to when purchasing a fingerprint lock. My friends, the plug-in can start from two aspects: one is the lock point of the plug-in, and the other is the material of the plug-in.

Look at the lock points: the lock points of fingerprint lock insert cylinder are mainly divided into single tongue and multiple lock points. The security of single tongue lock cylinder is worse than that of multiple lock points. It is generally used more in Japan and South Korea, but it is not suitable for the chaotic security environment in China. Therefore, it is suggested that domestic customers should clearly see the plug-in core when selecting fingerprint lock, and select multi-point plug-in core with function.

Second, look at the materials: the material of the plug-in core is the same as the shell, which is divided into plastic, alloy and stainless steel. Generally, the insert core will not be electroplated, which can be easily identified by customers. Because the plug-in core is placed in the door, many enterprises are more casual about the plug-in core materials. The industry generally selects stainless steel for the plug-in core, but alloy or plastic for the plug-in core shell. Such plug-in core not only has weak anti violence ability, but also has weak function, which is not conducive to security.

III. see additional services

The high-tech nature of fingerprint lock determines that it is not an ordinary commodity. It needs skilled personnel to use the device normally, and the problems encountered in the application process also need to be solved by technicians. Therefore, when purchasing, you should ask about the relevant after-sales service of the device, and suggest selecting a better brand and a brand with local exclusive stores or maintenance points, Generally, the installation parts of these brands are distributed after consistent training, and the skills and services are relatively guaranteed.
