How to choose a safe fingerprint lock
Fingerprint lock is an intelligent lock, it is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. So, is the fingerprint lock safe? As far as the technical indicators of the fingerprint lock itself are impeccable. If you want to make electronic locks and fingerprint locks truly perfect and impeccable, become a safe lock. Only by working hard on the emergency lock of the fingerprint lock and improving the technical performance of the emergency lock is the only way out of the predicament of the fingerprint lock technology.
Are fingerprint locks safe for home use?
The fingerprint lock is equipped with an emergency lock to prevent the fingerprint lock from being opened when the fingerprint lock fails. Usually, the fingerprint lock is an ordinary mechanical pin lock used as an emergency lock. It is precisely because the ordinary mechanical pin lock is used as an emergency lock for the fingerprint lock, which leaves the fingerprint lock with hidden safety problems and becomes a fatal flaw of the fingerprint lock. The defects of the fingerprint lock are caused by the following: the fingerprint lock is composed of electronic parts, the damage and effect of the electronic parts, the power failure of the fingerprint lock, and the artificial destruction of the fingerprint collector of the fingerprint lock may affect the normal opening of the fingerprint lock.
Assuming that the safety factor of the fingerprint lock is 10000, the safety factor of the ordinary mechanical pin lock is 0, and the safety factor after using the ordinary mechanical pin lock as the emergency lock of the fingerprint lock is 10000 X 0 = 0, all the advantages of the fingerprint lock are The shortcomings of being locked by ordinary mechanical pins are completely offset. It is to solve the problems of low key key quantity and high mutual opening rate of common mechanical pin locks, and to prevent thieves from using the master key to perform technical unlocking and the poor performance. To achieve the purpose of improving the safety performance of the lock. If the fingerprint lock uses an ordinary mechanical pin lock as an emergency lock for the fingerprint lock, then this becomes the same as the police asking the thief to stand guard, and everything is impossible to talk about.
If you want to make electronic locks and fingerprint locks truly perfect and impeccable, become a safe lock. Only by working hard on the emergency lock of the fingerprint lock and improving the technical performance of the emergency lock is the only way out of the predicament of the fingerprint lock technology. Digital locks, radio frequency locks, and eye pattern locks that belong to the same category as fingerprint locks all have the same fatal flaws as fingerprint locks.
1. Independent information management manages all user information and can freely add / modify / delete user information.
Advantages: It is very useful for users to manage user rights. Users can freely authorize, allow or prevent certain people from entering.
This function is more practical for users who have nanny or tenant at home. When the nanny or tenant moves away, they can immediately delete their fingerprints, so that they cannot open the door without the right to use. On the contrary, if there are new nannies and tenants, they can enter their fingerprints at any time, so that they can open the door freely.
In general, the biggest advantage of this feature is that you do n’t have to worry about the keys being copied by the nanny or tenant, reducing the insecurity at home.
Disadvantages: Multi-step operation is required to input and delete fingerprints, the procedure is more troublesome, and the convenience is not enough. However, the complicated operation is also for safety, and it is still acceptable for the time being. It would be better if the safety factor can be simplified while improving the operation procedures.
2. Voice operation prompt In the process of using, start the voice function, guide the user to open the door throughout the process, let the user know whether each step of the operation is correct, and prompt the user for the next operation.
Advantages: make the operation more simple and understandable.
This function is very practical for the elderly or children, so that they can be handy during the operation, and reduce their psychological repulsion of high-tech products because they do not understand the operation.
Disadvantages: Because the voice prompts are recorded uniformly, the voice is too mechanized, and the mobility and intimacy are not strong. In addition, the general voice operation prompts are only in Chinese and English. For elderly and children who do not understand these two languages, this function is virtually useless.
3. The anti-pry alarm function encounters abnormal opening and external violent damage, or the door lock slightly deviates from the room door, and immediately sends a strong alarm to attract people's attention, just like a car alarm.
Advantages: Strong alarm sound, can attract the attention of people around, effectively prevent the illegal behavior of thieves. For users with more complex central environments, this feature is more useful.
Disadvantages: The alarm system is temporarily unable to connect to the community or the police station security system, and cannot automatically alarm. This function needs to be improved for the more demanding confidential units. In addition, not every lock has this function and requires user customization.
4. The virtual password can add multiple or multiple sets of garbled characters before and after the correct password. As long as there is a continuous and correct password in this set of data, the fingerprint lock can be opened.
Pros: Prevent passwords from being stolen Disadvantages: The purpose of this feature is one of the most unused features discussed in the fingerprint lock world. Since the user can open the door with the correct password + garbled code, the thief must remember the password set that the user just used, and of course it can open the door. Unless the virtual password has the same password + garbled characters, the second function cannot be used.
5. Button remote unlocking Control the opening of the door lock within a certain distance through the remote control button. It is consistent with the automatic unlocking function of the car.
Advantages: higher intelligence and better meet the needs of different people.
For example, in a company, the company boss can lock the door of the office. When a subordinate knocks on the door, he does not have to go to the door to open the door, and the door can be opened directly by pressing the open button, which can also prevent visitors from entering inadvertently. If it is a mechanical lock, in order to facilitate employees to enter, the boss generally does not lock the door, which also facilitates the intruder. If the door is locked, the boss will often get up and open the door when the employee wants to report work, which is very inconvenient. This function just solves this problem.
6. Remote door opening This function is connected to the Internet, and the door lock can be controlled by mobile phone in any place in the world;
: Further enhance the intelligence of the fingerprint lock When parents, relatives and friends visit, and are not at home, they can use this function to remotely control the door lock to let them enter the door.
