Fingerprint lock is an intelligent lock, which is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Fingerprint authentication is convenient, fast and accurate. So, are fingerprint locks expensive? How to choose a fingerprint lock?
Fingerprint locks have been developed in China for more than ten years. If you said that a few years ago, I would not recommend you to make this kind of product, but if you say it now, I fully support your idea. In recent years, especially since 2008 last year, fingerprint locks have begun to develop and popularize very quickly. At present, many real estate communities in China have chosen fingerprint locks. The reason is very simple. Fingerprint opening will definitely replace the key to open the door. This is a big development direction.
Fingerprint lock price
A fingerprint lock at least has a fingerprint to open the door and a mechanical door. The mechanical key to open the door is stipulated by national law. If you add a password, a proximity card, etc. to open the door, the price will naturally be high. The price of fingerprint locks on the market varies, ranging from high to low. The ordinary fingerprint locks are between 1500 and 4000 yuan, and the villa type is higher. In conclusion, consumers need to comprehensively compare the cost-effectiveness of products according to their own needs and purchasing power. The general principle is that you get what you pay for.

First, look at the material
There are three main materials for making fingerprint locks, namely plastic, zinc alloy, and stainless steel. Among them, the durability, fire resistance and explosion-proof performance of plastic are the worst, followed by zinc alloy, and stainless steel is the best. Due to the complex domestic security environment, domestic fingerprint locks are generally dominated by zinc alloys, and a small amount of stainless steel fingerprint locks. In view of national conditions, domestic consumers are better to choose stainless steel fingerprint locks when choosing fingerprint locks, and they need to remember the purchase formula of “one look, two knocks, three weighing”.
Take a look: look at the exterior.
The fingerprint locks of the three materials have almost no difference in appearance, thanks to the superb electroplating technology of modern (modern decoration renderings), the appearance of different materials is almost similar to that of metal. The fingerprint lock made of plastic generally has a smooth surface and bright color, while the zinc alloy is slightly rough and sub-color, and the stainless steel is the most rough and sub-color.
Second knock:
If it is difficult to “see” the material of the fingerprint lock, we can use “knock” to judge. Gently tap the side of the lock body with your fingers (the front is not easy to judge due to the components of different materials such as the touch screen). If the sound is muddy or relatively empty, it is generally more likely to be a plastic product, and the stainless steel fingerprint lock is likely to be knocked The sound of hitting is sharp and concentrated, there is not much sense of diffusion, and the penetration is better. In view of the difference between the two, the sound of zinc alloy is not as sharp as stainless steel, but it is much fresher and clearer than plastic products.
Three weighing:
If you can’t judge the quality of the fingerprint lock by using the two methods of “look” and “knock”, then you can use the simplest and most useful method to measure, that is, “weighing” , we all know Which of these three materials is lighter or heavier, even if the internal weight of a plastic lock is very high (generally, the internal parts of a plastic lock are also made of plastic or its inferior materials), there will still be a certain difference between it and zinc alloy or stainless steel. .
2. Test function
The “trial function” mentioned here refers to “three openings and two degrees”, “three openings” refers to fingerprint unlocking, password unlocking and magnetic card unlocking, and “two degrees” refers to the response speed and accuracy, that is, to test these three The speed and accuracy of the door opening method.
First,
test the response speed and accuracy of fingerprint unlocking. Let the clerk enter your fingerprint first, which is also a step to verify the function of the fingerprint lock. When recording fingerprints, observe how easy it is for the clerk to enter fingerprints. If a fingerprint cannot be recognized after being entered many times, it can almost be judged that the resolution of the fingerprint lock is not high (the higher the resolution, the more accurate the identification, the faster the response, the safer the The performance is also better.
The current industry standard for fingerprint lock resolution is 500dpi, and the highest standard that can be achieved now is 560dpi of Digital fingerprint lock). After entering the fingerprint, randomly test the fingerprint lock’s recognition and response speed to the correct fingerprint. The faster the response, the higher the resolution and the better the lock’s performance. In the same way, if the real and fake fingerprints can be quickly identified, the accuracy will be good, and vice versa. It is best to try several times during the test. Only by testing several times can you better identify its pros and cons.
Second,
test the magnetic card and password to unlock. The test method of magnetic card unlocking and fingerprint unlocking is the same, and it is also to test its response speed and accuracy. Use authorized magnetic cards and unauthorized magnetic cards to test in the magnetic card area respectively to see the response and identification of the lock to the magnetic card. If the response speed is fast, then The performance of the lock is good, and vice versa. The password to open the door is also to measure the reaction speed and accuracy. The test method is also used alternately between correct and incorrect methods. The faster the response speed, the higher the technical content, and the higher the accuracy, the higher the security.

3. Look at the ferrule
When buying a fingerprint lock, in addition to looking at the lock body, the mortise is also a very important part, which is often ignored by consumers. Look at the ferrule from three aspects: look at the material of the ferrule, look at the lock point of the ferrule, and look at the function of the ferrule.
First
A look at the material: the material of the ferrule is divided into three types: plastic, alloy, and stainless steel like the outer shell. Generally, the ferrule will not be electroplated, and consumers can easily identify it. Since the ferrule is placed in the door, many companies are more casual about the ferrule material. In the industry, the interior of the ferrule is generally made of stainless steel, but the ferrule shell is made of alloy or plastic. Such a ferrule is not only weak against violence, but also fireproof. Performance is also weak, which is not good for security. Digil fingerprint lock is the only product in the industry where the mortise is made of stainless steel, and its sturdiness and fire resistance are dozens of times higher than ordinary materials.
Second,
look at the lock point: In addition to looking at the material of the mortise, you also need to pay attention to the lock point of the mortise. The lock points of the fingerprint lock mortise are mainly divided into two types: single tongue and multiple lock points. The safety of the single tongue lock cylinder is worse than that of the multi-lock point, and the anti-prying and explosion-proof performance is also poor. Therefore, it is recommended that domestic consumers should look at the mortise clearly when choosing a fingerprint lock, and choose a multi-lock-point mortise with explosion-proof and anti-pick performance.
Three functions:
Now the ferrules on the market are generally divided into hotel (hotel decoration renderings) lock mortise, lift-up mortise, generous tongue automatic pop-up mortise and multi-lock point self-elastic mortise. The hotel lock mortise can be opened with a card, which has poor safety performance; when the lift-up mortise is used, the handle needs to be lifted up when closing the door to lock the door, which is easy to forget to lock, which is not in line with the usage habits of consumers; the generous tongue pops out automatically The ferrule solves the disadvantage of lifting the ferrule, but still cannot automatically control the heaven and earth rod; and as the fourth-generation lock body, the multi-lock point self-elastic ferrule is the most superior mortise so far, with the strongest anti-theft function It is also the most convenient.
Fourth, look at additional services
The high-tech nature of the fingerprint lock determines that it is not an ordinary commodity. It needs to be installed by professional and technical personnel before it can be used normally, and problems encountered during use also need to be solved by professionals. Therefore, you must inquire about the relevant installation and after-sales services when purchasing. Serve.
Wrap Up Words
Due to the fierce market competition, many fingerprint door lock brands can now provide corresponding services, but due to technical and personnel problems, many companies outsource installation services to local lock installation or decoration personnel, which cannot solve customer problems well. When consumers choose locks, it is best to choose a well-known brand, and choose a brand with a local specialty store or maintenance point. Generally, these brands have professional installation departments, and the installation personnel are dispatched after unified training. And the service is more guaranteed.
