The advantages and disadvantages of smart fingerprint lock

1. Independent information management manages all user information and is free to add/modify/delete user information.

Advantages: It is very useful for users to manage user rights. Users can freely authorize and allow or prevent certain people from entering.

This feature is more practical for users who have nannies or tenants at home. When nannies or tenants move away, their fingerprints can be immediately deleted so that they cannot open the door without the right to use. On the contrary, if there are new nannies and tenants, they can register their fingerprints at any time so that they can freely open the door.

In general, the biggest benefit of this feature is that you don’t have to worry about the nanny or the tenant copying the keys, reducing the insecurity at home.

Disadvantages: It takes more than one step to input and delete fingerprints, the procedure is cumbersome and the convenience is not enough. However, the complicated operation is also for the sake of safety. For the time being, it is acceptable. If it is possible to improve the safety factor while simplifying the operating procedures, it would be better.

2. Voice operation prompts In the course of use, start the voice function, guide the user through the door opening operation, let the user know whether the operation of each step is correct, and prompt the user for the next operation.

Advantages: Make operations easier and easier to understand.

This function is very useful for the elderly or children, so that they can be handy during the operation, reducing their psychological exclusion of high-tech products because they do not understand the operation.

Disadvantages: Since voice prompts are recorded in a unified way, their voices are too mechanized and their mobility and intimacy are not strong. In addition, the general voice operation prompts only Chinese and English. This function is ineffective for the elderly and children who do not understand the two languages.

3. The anti-smashing alarm function encounters abnormal opening and external violent destruction, or the door lock slightly deviates from the door, and immediately emits a strong alarm, attracting attention, like a car alarm.

Advantages: a strong alarm sound, can attract the attention of people around, effectively prevent the thieves from illegal acts. For more complex users in the middle environment, this function is more useful.

Disadvantages: The alarm system cannot be temporarily connected to the district or police security system, and cannot be automatically alarmed. This function needs to be improved for more demanding security units. In addition, not every lock has this function and requires user customization.

4, virtual password can be added before or after the correct password in more than one or more groups of garbled, as long as there is a continuous and correct password in this group of data you can open the fingerprint lock.

Advantages: Prevent passwords from being sniffed. Disadvantages: The use of this feature is one of the most unusable features discussed in the fingerprint lock community. Since the user can use the correct password + garbled code to open the door, the thief must be remembering the cipher suite the user just used, and of course the door can be opened. Unless the virtual password has the same password + garbled characters, the second function cannot be used.

5, button remote control unlocked through the remote control button, within a certain distance to control the opening of the lock. Same as the auto unlock function.

Advantages: higher intelligence, better meet the needs of different groups of people.

For example, in the company, the company boss can lock the door of the office, when the subordinates knock on the door, do not have to go to the door to open the door, directly press the door open button to open the door, but also to prevent the looming visitors. If it is a mechanical lock, in order to facilitate the entry of employees, the boss generally does not lock the door, which is also convenient for those who rashly enter. If you lock the door, it is inconvenient for the boss to get up and open the door when the employee wants to report the work. This work just solves this problem.

Disadvantages: Can not be connected to the Internet, can only control the door lock through a control button within a certain range.

6, remote control to open the door This function is connected to the Internet, in any place in the world can control the door lock through the phone;

Advantages: Further enhance the intelligence of the fingerprint lock When parents or relatives and friends visit, when they are not at home, they can use this function to remotely control the door lock and allow them to enter the door.

Disadvantages: When no one is at home, if you accidentally touch this feature to open the door, and you do not pay attention, the consequences are disastrous.
