About fingerprint locks, these 6 questions you must know-media reports

In recent years, with the continuous implantation of the fingerprint lock product in TV series, I believe many people are familiar with it. The emergence of fingerprint locks has brought the most direct change to people’s lives without having to go out with a key. I believe many people have lost their keys. Every time they can’t enter the house because the key is missing, they hate themselves why they don’t install a fingerprint earlier. Lock. Due to work, I have come into contact with many fingerprint lock products, and I have also encountered and dealt with many problems encountered during the purchase process, installation process and daily use of the fingerprint lock? Today I have summarized 7 points to share with you. I hope that you will have a pleasant shopping experience in your purchase of fingerprint locks. 1. Is the door of the home suitable for installing fingerprint lock? Before buying a fingerprint lock, you must understand that the fingerprint lock must be matched with your home door, because the doors of Chinese homes are all kinds, you must make the following preparations before placing an order: Determine the direction of your home door, whether it is left or right Open, use a measuring tool to measure the length of the lock body guide piece and take a picture, measure the thickness of the door, and determine the lock body of your door. Of course, you don’t have to unlock the body, just take a picture and send it to the merchant, and finally determine whether your door is There are heaven and earth hooks. With these preparations, you can go to the merchant to buy a fingerprint lock to save you a lot of time. 2. How to tell whether the price of the fingerprint lock is reliable? Regarding the price of fingerprint locks, if you have visited a certain treasure, you will definitely find that the price of fingerprint locks ranges from a few hundred to tens of thousands of yuan. The price difference is so large that it is mainly determined by the brand, style and function. The relatively reliable price range is between 1,500 yuan and 5,000 yuan, which is suitable for most consumers. The price is less than 1,000 yuan to choose carefully, because the fingerprint lock is different from other products, once the after-sale quality problem occurs, it is still very inconvenient to repair. 3. Fingerprint recognition module: Which is better, optical fingerprint recognition and semiconductor? The general opinion on the Internet is that semiconductor fingerprint recognition is better than optical fingerprint recognition, but this statement is actually not scientific. In fact, in terms of sensitivity, the efficiency of optical fingerprint recognition and semiconductor recognition are similar. I think the biggest advantage of optical fingerprint recognition is that it is resistant to moisture. A bit of sweat on the hand will not be affected. Optical recognition will not be affected, but semiconductor fingerprints cannot be recognized, such as Apple mobile phones. Semiconductor identification can basically not be identified only if there is sweat on the hands. The cost of semiconductor identification will be higher than that of optics, so you will find the same product for semiconductor fingerprint locks, the price is about 100-200 yuan higher than that of optical identification. The biggest advantage of semiconductors is that they have strong anti-counterfeiting fingerprint capabilities, that is, relatively high security. From this point of view, optical fingerprint recognition is likely to leave fingerprints and leave certain security risks. In summary, in fact, optical fingerprint recognition and semiconductor fingerprint recognition should not be too real, each has its own advantages and disadvantages, as long as you don't buy inferior fingerprint recognition modules. 4. How safe is the fingerprint lock compared to the mechanical lock? At present, fingerprint locks are required by the country, and fingerprint locks need to have a spare mechanical key to unlock, but the security of the lock cylinder is better than most traditional mechanical locks. Basically I think that the current lock cylinders of fingerprint locks are all C-level lock cylinders, and they are anti-technical. If the opening time exceeds 270 minutes, the average thief will give up as long as he can't open it for more than 2 minutes. From this point of view, fingerprint locks are more secure than mechanical locks. But it cannot be said that the fingerprint lock is absolutely safe. For example, the Tesla coil opened a lot of fingerprint lock products in seconds last time, and some networked fingerprint locks also have some loopholes, so make sure that you buy a fingerprint lock that is relatively safe. Choose professional brands and regular manufacturers. Because regular fingerprint lock manufacturers generally have a special product testing process before they leave the factory to ensure the safety of the products before they leave the factory. 5. Can the fingerprint lock be installed by itself? Is the manufacturer responsible for on-site installation? At present, most fingerprint lock manufacturers are responsible for the installation. Generally, installation fee is required for installation. Generally, the normal installation fee is 200-300 yuan. Before you buy, most manufacturers include the installation fee. Of course, users can choose to install it by themselves. If you have a local locksmith who can install the fingerprint lock, you can also find it locally. At present, most fingerprint lock manufacturers cannot do the installation problems. 24 hours onsite. The installation of fingerprint locks is basically impossible for ordinary consumers to complete by themselves, so installation needs to be cautious. 6. What should I do if the fingerprint lock is out of power? There is basically no need to worry about this problem anymore. More than 80% of the fingerprint locks on the market have a low battery reminder function and an emergency charging power interface, which is really not good. You can also use the emergency key to open.
