What are the different types of smart locks, and which one is better?

Such as: fingerprint lock, iris recognition access control (biometrics, high security, no loss or damage; But it is inconvenient to configure and the cost is high). Magnetic card, radio frequency card (non-contact, high security, plastic material, easy to carry, low cost).

TM card (contact, high security, stainless steel, extremely convenient to carry, ** low).

The remote intelligent password lock makes use of the software and hardware resources of the system single-chip microcomputer, introduces the intelligent analysis function, and the reliability and security of the system are higher.

Hello, smart lock is a lock that combines electronic technology, integrated circuits, electronic components, and a variety of identification technologies to identify users, security, and management. Generally, smart locks include fingerprint locks, password locks, induction locks, etc., which can be selected according to needs.

Fingerprint lock is a smart lock with human fingerprint as the identification carrier and means, and the fingerprint lock is generally composed of two parts: electronic identification and control and mechanical linkage. The uniqueness and non-reproducibility of fingerprints make the fingerprint lock function stable and highly secure.

The password smart lock is opened with a string of numbers or symbols, and the password lock is to turn a set of several dial wheels engraved with numbers to drive the mechanical operation inside the lock.

The induction lock is controlled by the single-chip microcomputer on the circuit board to start and close the door lock motor, and the door lock can be unlocked by the card issued by the computer. When issuing a card, you can control the permission to open the card.

How to choose a smart lock? I think under normal circumstances, when choosing a smart lock, you still need some handprints or passwords, and I think it's better to do this.

I have specifically studied,When you choose a smart lock, you have to look at the rejection rate and the false recognition rate,The false recognition rate is the probability of unlocking the fingerprint authentication after the successful entry,If the false recognition rate is too high,The security of the door lock is not guaranteed。 The rejection rate refers to the probability that the fingerprint authentication that has been entered cannot be unlocked, if the rejection rate is too high, the convenience of using the smart lock will be greatly reduced, these two points are selected, basically there will be no mistakes, I recommend you Philips smart lock, security and sensitivity are good.

Due to the convenient and fast life brought by smart home, more and more people are looking forward to having an intelligent life. Smart lock is an aspect of smart home, many friends who are new to home smart door locks, do not know how to buy smart locks, the author talks about how to choose a good smart lock from the following aspects. Smart lock brand.

1. Security.

As the first security barrier in the home, the door lock is used by people every day, and security is the most important factor. In the face of smart door locks at different price points, different materials and functions, what are the differences in their security?

The national standard has formulated three security levels for the lock cylinder, which are A, B, and C levels, and the anti-technical opening time is 1 minute, 5 minutes, and 270 minutes respectively. When choosing a smart lock, a C-grade lock cylinder is the first choice. The best material of the lock body is 304 stainless steel, which is durable, strong and reliable, wear-resistant, and not easy to rust.

Since the electronic lock is unlocked by the motor driving the clutch, the motor and clutch must be durable, and the two parts must be in the lock body to avoid violent unlocking.

2. Branding. Smart locks have only developed on a large scale in recent years, and in order to compete for this cake, hundreds of companies have joined the smart lock industry. In addition, in order to seize the first entrance of this smart home, Internet companies have also launched smart lock products.

According to incomplete statistics, there are currently more than 1,000 smart lock companies in China. In the face of such a mixed situation, when consumers choose smart locks, they must have an in-depth understanding of the manufacturer and choose a company with a long and powerful brand. For example, Keyu Intelligence, a well-known high-tech enterprise in the industry, has 25 years of experience in manufacturing smart locks, integrating product development, production, sales and maintenance.

In recent years, with the rise of smart home, many Internet companies are optimistic about the first entrance of smart home - smart door lock. In order to integrate smart homes, Internet companies have invested in the product of smart locks, and even launched one after another low-cost smart locks at any cost. However, the door lock is the first security barrier in the home, when we choose a smart lock, we should choose the products of traditional enterprises, because the door lock is not an accessory in home life, and the technology of manufacturing door locks needs to be continuously accumulated and improved.

3. Fingerprint head.

At present, there are two main types of fingerprint heads for smart locks: optical fingerprint heads and semiconductor fingerprint heads. Optical fingerprint heads are easy to be copied, causing potential safety hazards, and semiconductor fingerprint heads are highly secure and generally not easy to be copied.

Keyu smart lock adopts Swedish FPC nano-ceramic fingerprint head, using living biotechnology, the more you use, the more flexible, identifying, and open with one touch.

Fourth, after-sales service.

With the development of the Internet, consumers can now easily buy smart locks online, but complaints about installation and after-sales have also followed. The installation and maintenance of smart locks need to be operated by professionals, and when buying smart locks, it is necessary to understand whether the manufacturer has a perfect after-sales service system.
