As a high-tech smart home product, smart locks are recognized and sought after by more and more users. However, our understanding of smart locks is still not very comprehensive. In the case of buying in the follow-up state, many small smart lock companies and products have entered the door lock security market through false packaging. The following is a brief discussion of three major mistakes that users need to avoid when choosing a smart lock.

When buying smart locks must avoid these three errors

1, optical acquisition technology is not as good as semiconductor acquisition technology

Obtaining the fingerprint image is the most important part of the smart lock work. Therefore, the fingerprint collection becomes the main point of competition for each brand, and it is also the selling point of the sales person. In the store, we can often see the sales staff eloquent to explain the advantages of their own acquisition technology to the customer, the most common is: "Do not use the smart lock of the optical acquisition, cracked with a fake fingerprint. Semiconductor is better, the image Clear, one can identify fake fingerprints." So, in the smart lock acquisition, optical acquisition technology is really as good as shopping guides say, as good as semiconductor acquisition technology?

Facts At present, there are three types of fingerprint acquisition technologies: optical acquisition technology, semiconductor acquisition technology, and ultrasonic acquisition technology. Ultrasonic acquisition technology is highly technical, but due to its high cost and in the experimental stage, it is hardly used in smart lock recognition systems. The semiconductor acquisition technology was born in 1998. It can instantly capture and timely adjust the image, which is more accurate than the optical image, but it is easily affected by the static electricity, sweat, dirt, finger wear and other conditions, resulting in the sensor can not get the image, or even be It is damaged; it is not wear-resistant and has a short life span. Therefore, its application range is relatively small. Optical acquisition technology is the oldest fingerprint acquisition technology. It has undergone long-term practical application tests, can withstand a certain degree of temperature changes, has good stability, and is sensitive to identification. Its acquisition instrument is generally made of tempered glass and is very wear-resistant. Effectively extend the service life. In view of the above advantages, optical acquisition has become the mainstream fingerprint collection technology on the market, and is widely used in the management of fingerprint locks, fingerprint access control, fingerprint punching machines, and car fingerprint anti-theft devices. As far as the current level of technology is concerned, in the area of ​​fingerprint locks, optical acquisition is slightly better than semiconductor acquisition.

2, smart lock without a key

Some salespeople introduce smart locks to consumers. They often emphasize that their products only use fingerprints to open the door. They don't need keys. Smart locks with keys are inferior products. So, does the smart lock really have no keys?

The fact is that smart locks are the crystallization of technology in many fields such as mechanical functions, electronic technology, and bioengineering. The operation of mechanical functions and electronic technologies has certain limits. The phenomenon of strikes is unavoidable. For example, the battery is dead. And the password will not work. Especially when there is a fire or gas leak, the use of a key to open by outsiders will be the key to rescue trapped people. Experts of Hollis Smart Lock: “The relevant national laws expressly stipulate that smart fingerprint lock must be equipped with a key opening function at the factory to prevent the malfunction of the smart lock in an emergency situation. Therefore, a smart lock without a key does not meet the current national conditions. ”

3, the more expensive the better

Smart locks have always been the “fine decoration material” in the home building materials market with noble quality. People always think that their prices are definitely more expensive and better. Sales staff often use this knowledge of customers to constantly recommend various high-priced smart locks to customers. Is the smart lock really more expensive?

In fact, smart locks, as high-tech intelligent products, require the use of more expensive materials and require a variety of high-tech skills as support. The material costs and technological costs determine that smart locks are not low-priced products, but this does not mean that smart locks The more expensive the price, the better its quality. According to a research and development expert of Hollis Smart Lock, “The price of an ordinary smart lock product is reasonable around 2000-3500, and the price of the smart lock material and technology are to achieve a higher level in the industry. If the price is higher than this value, only two One possibility is that the product is made of special materials such as stainless steel or gold-plated silver; the second is that this product is unique in appearance design, and the price is expensive in the form design. When the user encounters the design or material, When prices are billed for thousands of smart lock products, they need to think twice.

In summary, these three misunderstandings must be avoided when selecting smart locks, so that they can exclude some shoddy products.
