The following aspects of smart door locks are very important to users.

Smart lock is one of the most popular smart home products at present. In the new era, three-free smart locks can make home security smarter and life more stable. So what should I pay attention to when buying a smart lock?

1. Environments where functions should be merged.

When choosing home smart door locks, we should choose according to the environment, conditions and requirements. Functional requirements should be determined according to the application, because different use environments have different functional emphases.

2. Intelligence level

In the Internet of Things era, using mobile terminals to realize intelligent operation at home is one of the criteria to distinguish whether it is really "intelligent". Nowadays, fingerprint locks and password locks on the market dare to be called "modern smart locks", which is a joke for people in the industry. This consumer really needs to polish his eyes! The three-free smart lock has the advantages of "no electricity", "no networking", "no maintenance" and "APP unlocking", and is more intelligent. The cloud server can realize various control and authorization functions. By swiping the lock, the lock module chip, the APP and the cloud can instantly complete a series of security authorization encryption operations to confirm the user's lock control authority.

Through the authorization verification technology system, intelligent locking and control functions such as authorization unlocking operation and background management can be realized in different application scenarios.

3, to deal with complex environment, the product has strong adaptability.

Due to the complex installation environment of smart lock products, the impact on the environment is also considerable. Such as wireless signal docking, signal interference, signal shielding, etc. , will directly affect the use experience of the lock. Many so-called smart locks rely on Wi-Fi environment, which is useless once the network is lost. Three-free smart lock adopts NFC, which has been widely used at present.

Mature communication technology, through the NFC function of mobile phone or special handset, communicates with the lock control circuit near the surface of passive smart lock, and completes the functions of authority check and wireless power supply, that is, the lock control circuit can complete the four closed-loop functions of NFC wireless communication, checking algorithm operation, electromagnetic energy conversion control and power supply control for lock mechanism, so there is no power supply module and traditional communication module in the lock body, and the management function of intelligent lock in the Internet of Things can also be realized.

4. Security of software system

Support algorithm encryption

And a security chip.

Strict safety technology system

Use a lock to ensure peace of mind

The security system supports algorithm encryption and security chip to ensure the peace of mind when using the lock;

NFC is an international standard communication protocol, which has been widely used in secure payment and authorization scenarios.

The characteristics of NFC near-field communication can effectively avoid the risk of illegal interception of wireless communication signals;

The NFC power-free smart lock module is embedded with a dynamic authorization verification algorithm, and the cloud, APP and lock chip are linked to verify the identity authority at multiple levels to ensure that the lock right cannot be cracked and copied;

This module supports the expansion of financial-grade security chips, and the security inspection mechanism is more rigorous; The real name and identity of the user are bound in the background, and the time and device number of each locking operation are recorded in the cloud, and the operation records can be traced back.

In addition to the problems mentioned above, other conveniences such as low price and cost, appearance design, installation technology and after-sales service should be considered comprehensively in order to purchase the most suitable smart lock.
