Smart locks are locks that are different from traditional mechanical locks in terms of user identification, security, and management. A smart lock is an executing component of a door lock in an access control system. So which one is smarter to choose safer?

Why choose a sensor lock?

The large amount of information stored is the advantage of the induction lock card. It not only serves as a key, but also loads multiple personal information. It is particularly suitable for the financial industry to focus on the industry characteristics of “examination and recognition” and it is also versatile with one card (such as entry, unlock and storage). , payment, etc.) bring cardholder convenience. The use of such electronic anti-theft locks requires careful storage of the card and the loss of the authorization to cancel the card as soon as possible.

What are the disadvantages of sensor locks?

There are many types of sensor locks, and there are differences in security. Low-end products, such as community access cards, and a few yuan, have poor security; in addition, cards are like keys and cannot be forgotten or lost, so there is no advantage that other smart locks do not need to be carried, and Cards are more vulnerable to damage than keys.

What are the advantages of biological locks?

Some of the inherent personality traits of human beings, such as the features of hands, eyes, and sounds, are almost impossible to duplicate. As the "key" is the only one. Therefore, electronic security locks that use biometrics as passwords are very safe.

Is there any disadvantage to biological locks?

Biological locks are produced with the development of new technologies for biometric identification. At the current stage, most biometric locks are not stable enough and are expensive. In the case of extremely high confidentiality, it is not appropriate to use biometric electronic anti-theft locks alone. It is better to combine other electronic information as a password.

Why are so many people using fingerprint locks?

1, security. Ordinary mechanical lock keys can be copied, and the owner is not assured when they are used. Fingerprints are unique. There are no two identical fingerprints in the world.

2, convenience. You don't have to carry your keys with you, but you never lose your keys. A person's fingerprints will remain unchanged forever. You can use fingerprints at a time and you can use them for life. And one can input fingerprints of different fingers. Touch to open it, unlock it.

3, scalability. It can hold 199 fingerprints, and it can register fingerprints at will, delete fingerprints, and manage fingerprints very conveniently. Compared with ordinary mechanical locks, it can save the troubles of key preparation and key recovery. It is especially suitable for office and rental rooms.

4, can set 8 groups of passwords, and has a password to prevent peeping. And fast operation, password can be replaced at any time.

5, long-term maintenance-free. Ordinary mechanical locks have a short service life and are prone to failure during use. They have to break in, and fingerprint locks do not fail.

6, high recognition rate. The refusal rate is less than 1%, and the falsification rate is less than one millionth. The fingerprint can be correctly compared within 360° of any angle.

7, fashion. Fingerprint password technology is the development direction of locks. The use of fingerprint password locks represents fashion, dignity, and cutting-edge. Fashion design and generous.

The disadvantages of fingerprint locks are also not to be ignored

1. Some people or some groups have few fingerprint features and are difficult to image.

2. Each time the fingerprint is used, the user's fingerprint imprint is left on the fingerprint collection head, and these fingerprint traces may be used to copy the fingerprint.

3, password lock stability and durability without strong mechanical password.

Smart lock purchase

Smart lock purchase - sensor lock purchase

In addition to the method of selecting the smart lock mentioned in the code lock, when the sensor lock is selected, the quality of the sensor lock can be judged according to the following methods.

First, test the sensitivity of the induction key card

Repeatedly inserting the card or sensing the key card to open the door should operate normally. There should be no "no response" or "error" or "motor rotation" phenomenon.

Second, understand the static power consumption of the sensor door lock

Selecting the sensor lock first checks its sensing sensitivity and then knows the static power consumption of the sensor lock. Because the general sensor door locks are powered by dry batteries, some brand induction door locks can be used continuously for more than one year, while some brands replace the battery in less than a month. Frequent battery replacement will seriously affect the use.

Third, pay attention to the quality of the card

The sensor lock card can be divided into IC card, TM card, magnetic card, now the most used is IC contact door lock, IC card door lock is generally used Siemens card. At present, there are many companies that make cards, and many smart lock manufacturers use smaller card manufacturers to manufacture chips, which cannot guarantee the quality of the chips. Therefore, in order to ensure the quality of the card, it is recommended to choose a strong brand name product.

Smart lock purchase - fingerprint lock

Although fingerprint lock is a product with high security, there are many fingerprint locks with unstable performance on the market. For example, it is impossible to identify the fingerprints of some people, and after the fingers are damaged, they cannot be well-identified. Therefore, in order to prevent all kinds of headaches after the installation of the fingerprint lock, when buying it, please pay attention to the following two points.

1. See if the fingerprint lock has ANSI certification

The real fingerprint lock was introduced to China from the United States. At the time, the high-end fingerprint lock brand in the United States Di Ji and the world's top 500 companies Ingersoll Rand dominated the high-end fingerprint lock market. Therefore, generally reliable fingerprint locks must pass the highest ANSI certification in the United States. ANSI certification as the highest level of the world's most stringent quality certification, product quality assurance and symbol.

2. It is best to select the fingerprint lock of organic electricity conversion function

Fingerprint locks are electromechanical products. According to national standards, emergency mechanical keys need to be added. However, security holes are left behind. The fingerprint lock with electromechanical conversion function can realize that when the fingerprint is locked in the normal state, the emergency mechanical keyhole is idling, and the door lock cannot be opened. Only when the electronic part cannot work normally, the control part of the lock body will pass the computer chip. The mechanical keyhole is activated to open the door, thereby reducing the possibility of the emergency key being opened unlawfully.
