At present, in order to pursue profits, reduce the cost, and reduce the quality of the product, many manufacturers use the cast iron (easily rusted, non-preserved) that is eliminated as the raw material for lock production, resulting in problems with the quality of the product. However, these internal material-changing locks are difficult to distinguish between appearance and quality. It is understood that the quality of locks, but off, material, panel thickness and other issues caused by the stability of the locks and anti-theft performance standards, this situation should arouse the attention of users.
In addition to quality, what kind of lock is best to buy? Or what kind of lock is the safest? Many locks have already been eliminated due to their low safety, and they may be seen in museums. Nowadays, the more common locks are divided into two types: marbled mechanical locks and electronic smart locks. Billet lock is the most commonly used lock in the world. Smart lock is a new type of lock that appears with the development of electronics and other technologies. It is the direction of lock development in the future, and the market share is increasing.
Advantages and disadvantages of mechanical locks and intelligent lock <br> <br> comparative advantage: the price is relatively low; high degree of market awareness; a relatively strong panel; high-quality mechanical lock intelligent anti-theft is also good to open a high technology capabilities, security Higher, and not afraid of forgetting to bring keys.
Disadvantages: Ordinary mechanical lock anti-technical opening ability is low; the key is easily lost or even copied; daily forgetting to bring the key will cause inconvenient prices generally higher; market awareness is low; civil intelligent locks generally leave a mechanical emergency key hole, there is Security loopholes.
There is no absolute safe lock in the world. The anti-unlocking and unlocking technologies are like spears and shields. Both are constantly improving. The mechanical lock is more practical and the price is lower. The smart lock is the development direction of modern social locks, it is safer and the operation is also convenient. However, there are also some disadvantages. When consumers choose, they need to consider in many ways. Choice.
Smart Lock Product Category:
1 The password lock is unlocked by the password, which can be divided into two types: mechanical password lock and keyboard password lock.
2 induction lock IC card lock: sub-contact IC card lock and non-contact type. Contact-type card locks will be stitched, and the internal reader of the chip lock will be in contact with the non-contact type. This process is not needed. It is only necessary to put the card and the lock reader together.
3 electromagnetic lock: the application of electromagnetic principles, the electromagnetic force of several hundred kilograms, locked state, most people can not open with this. Fatal point, power failure can not be closed, it is generally used in the door of the guard on duty, used for the room door and the mechanical lock supporting the use.
4 Biological lock: With the development of biometrics technology, fingerprint locks, palmprint locks, and retina recognition locks have emerged.
Smart locks are locks that are different from traditional mechanical locks in terms of user identification, security, and management. Smart locks are made using electronic technology, integrated circuit design, and a large number of electronic components, combined with a variety of innovative identification technologies. The current smart locks mainly include three types: password lock, sensor lock, and biological lock. As the product matures, smart locks gradually begin to enter large numbers of ordinary people.
Lock two categories of three shopping tips <br> <br> locks, as the name suggests is to unlock password, it can be divided into mechanical lock and keyboard lock two kinds. A coded lock is a type of lock that is turned on using a series of numbers or symbols. There are mainly two types of coded locks, one is a dial type mechanical code lock, and the other is a more intelligent keyboard coded type lock, and there are two kinds of buttons and touch screens. Find out separately below.
1, mechanical combination lock dial introduce <br> <br> dial lock is similar to the old telephone dial-up, from the beginning of the dial, turn the dial clockwise to a digital one, and then return to the starting point, Just entered a password. This repeats until the last password is entered and the dial can be unlocked by turning the dial counterclockwise from the starting point. At the same time when the lock is unlocked, the interior has been reset, so after the dial has returned to the starting point to close the lock, the password must be re-entered to unlock, and there is no need to consider the internal reset problem.
Dial mechanical combination lock dial-type lock <br> <br> advantage of dial-type locks generally have six password, the password can be six groups have more than 2.98 million people are free to change the password for confidentiality pole high. In addition, the number of passwords and passwords can also be redesigned according to the needs of users. An alarm interface can also be added to the user. No key, no power supply, no battery, safe and reliable, full mechanical structure, able to withstand a rather harsh external environment, a wide range of uses.
The disadvantage is that some padlocks can tighten the lock and turn the dial until it can no longer be moved, so that the password can be found. There is also a certain relationship between the numbers of dial locks, which greatly reduces the possibility of combination of passwords. Cheap padlocks can be opened with special linings without using a password.
Dial-type locks are safer and are generally used for safes, safes, filing cabinets, etc. However, the dial-type password lock is relatively rare on the home door. The reason may be that the operation of the dial-type password lock is relatively complicated, and the keyboard-type password lock has a more convenient operation as a substitute. Just like a keypad phone replaces a dial phone.
2, the keyboard lock is <br> <br> from the current level of technology and market acceptance of view, the most widely used or electronic key code lock. The keyboard-type electronic password is entered on the keyboard, which is similar to the telephone call, so it is easy to grasp. Its outstanding advantage is that the "password" is a number or character that is recorded in the authorized person's head. It is accurate and reliable, and will not be lost (except forgotten) and difficult to be stolen (unless it is revealed by itself). If the password is compromised, the password lock will be useless.
Keypad type password lock password lock password lock function. Therefore, to ensure the security of the password lock, the key is to ensure the security of the password. At present, many password locks have "arbitrary set password" technology, "automatic password change" technology, "keyboard out of order display" technology, "multiple password setting" technology, etc. to ensure that passwords are not leaked. Despite the emergence of new electronic anti-theft locks, keyboard-type electronic password anti-theft locks are still in the mainstream in the market, but also often used as an auxiliary input means for other types of anti-theft locks.
3, optional password lock Weapon <br> <br> following the purchase method, may not only apply to the purchase of locks, also applies to the purchase of the majority of the intelligent lock. Closer to home, when choosing a code lock, it mainly depends on three aspects.
First, look at the manufacturers to see whether the manufacturers can provide formal inspection reports, formal manufacturers can provide the national authoritative department is mainly * Department of the safety certification certificate, a comprehensive quality management system, through the international market standards, has its own patented technology . Only qualified manufacturers' products can be used with confidence.
Second, look at the door lock software system stability Most anti-theft electronic code lock manufacturers have to emphasize their own hardware devices, everyone does not know, anti-theft electronic code lock software system is very important, which is directly related to the security level of anti-theft electronic code lock. The excellent anti-theft electronic code lock adopts the chip and embedded program of the world's top suppliers, and the software technology is mature and reliable.
Third, look at the product installation service password lock is installed correctly, directly related to product safety and service life. Only the installation of professional technicians can ensure that the use value of products is not impaired, and at the same time, the interests of users will not be damaged. If only products are provided and professional installation services cannot be provided, or if users need to solve installation problems, such electronic lock products are not recommended.
<br> <br> sensors lock sensor lock or IC card lock, and the lock sub-contact IC card and contactless. Contact-type card locks will be stitched, and the internal reader of the chip lock will be in contact with the non-contact type. This process is not needed. It is only necessary to tie the card and the lock reader together.
It is actually more common for sensor locks to be used on doors, such as the door of a community card, the door in a hotel room, etc. There are many categories of sensor locks. Before purchasing, you need to understand clearly and know the precautions for purchasing.
1. Classification of sensor locks Sensor locks generally use various “cards†as keys. No matter how many types of cards are used, according to the operation mode of input cards, they can be divided into contact cards and contactless cards. At present, the contact card technology is mature, the price is low, and the application is also more extensive; the use of contactless cards is hidden and convenient, and there are great potentials to come from behind.
2. Advantages of sensor lock The large amount of information stored is the advantage of the sensor lock card. It not only serves as a key, but also contains a number of personal information. It is particularly suitable for the financial industry to focus on the industry characteristics of “examination and recognitionâ€, and it can be used with more than one card ( Such as entry, unlock, 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.
3, induction lock disadvantages Sensor locks are also divided into many categories, there are differences in theft prevention. Low-end products, such as community access cards, and a few yuan, have poor security; besides, cards are just 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.
4, induction lock purchase tips In addition to talking about the password lock mentioned in the purchase of smart lock method skills, in the purchase of sensor lock, you can also determine the quality of the sensor lock according to the following methods.
Test the sensitivity of the induction key card <br> <br> a sensitive test induction key card to open the door after repeated continuous card or token card should function normally, there should be "no response" or "Error", "Motor Indiscriminate phenomenon.
Second, understand the static power consumption of the sensor door lock Select the sensor lock first check the sensitivity of the sensor, and then understand the static power consumption of the sensor door 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 card's quality sensor card lock can be divided into IC card, TM card, magnetic card, now the most used is the IC contact door locks, IC card door locks generally use Siemens cards. At present, there are many enterprises that make cards. Many smart lock manufacturers use smaller card manufacturers to make cards, 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.
<br> <br> biometric locks biometric locks with biometrics technology, fingerprint lock appeared, palm prints locks, retinal recognition lock. Fingerprint lock is a type of biological lock, and it is also a kind of smart lock that is commonly used. Other iris recognition locks, palmprint locks, etc., are currently used less frequently. Therefore, the fingerprint lock category is mainly introduced next.
1, the advantages of biological locks Some of the inherent personality characteristics of people, such as the characteristics of the hand, eyes, voice can not be repeated, as the "key" is the only, so the use of biometrics as the electronic anti-theft lock, Security is very high.
2. The disadvantages of biological locks Biological locks are produced with the development of new technologies for biological identification. At the present stage, most biological 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.
3. Fingerprint Lock Introduction Fingerprint lock is a biological lock that is relatively widely used at present. The uniqueness and non-replicability of fingerprint determines that the fingerprint lock is the safest kind of lock in all current locks. Fingerprint lock is usually composed of two parts: electronic identification and control, and mechanical linkage system. Through the use of fingerprints as input signals, the fingerprint locks are identified and processed to control the implementation of mechanical actuators.
According to the classification of identification carriers, fingerprint locks can be classified into two types: optical fingerprint locks and semiconductor fingerprint locks. Optical fingerprint lock is relatively stable and adaptable. It is mostly used in anti-theft locks. It occupies more space than semiconductors, and can still be used after being scratched by metal hard objects. Semiconductor fingerprint locks are relatively small in volume and have a wider range of identification than optics, especially for dry fingerprint users. However, semiconductor fingerprint locks have high requirements for the use of the environment and are easy to scratch. It is generally used by a person to look after the place.
4. Fingerprint locks Although the fingerprint lock is a relatively safe product, 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 recognized. Therefore, in order to prevent all sorts of headaches after the installation of the fingerprint lock, when buying it, please pay attention to the following two points.
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 led 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.
It is best to select the fingerprint lock of the organic electricity conversion function. The fingerprint lock is an electromechanical product. According to national standards, it is necessary to increase the emergency mechanical key. However, it leaves a security hole. The fingerprint lock with electromechanical conversion function can realize that when the fingerprint is locked in the normal state, the emergency mechanical key hole is idling, the door lock cannot be opened, and 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.
