In order to prevent theft, many companies and communities have now enabled electronic access control systems, mainly credit card access control systems. With the news of random copying of access control cards in many communities in the past two years, users have questioned the safety factor of the card access control system, and more secure access control systems urgently need to enter the access control market.
Fingerprint access control and card access control
The traditional swipe card access control issues access cards to authorized users, but the access card technology is too simple and easy to be copied. Those who have access control cards are no longer limited to legal users, and the access control system is difficult to play the role of anti-theft.
In the face of common electronic access control systems, for thieves, the easiest way to verify the password is undoubtedly the password input, especially for the elderly or children users, the thief is easy to peek or set out the access code, the password security at this time The protection index is almost zero. Although the access control card can be kept for the user, the current proliferation of access control card copying and the low cost almost make the access control card a kind of decoration, and thieves can easily obtain a copy of the access control card and enter and exit the building at will.
The new access control system uses biometric technology to lock the authority firmly on the legal user. Biometrics is based on people's unique biological characteristics, unlike access control cards that can be copied at will. Among them, fingerprint access control systems are the most representative.
The earliest application of fingerprint identification system and the detection of police criminal suspects have a history of more than 30 years, which has laid a good technical foundation for the research and practice of fingerprint identification. In particular, the current fingerprint identification system has reached the stage of convenient operation, accuracy and reliability, and moderate prices, and is gradually being applied to the civilian market.
Fingerprint access control replaces traditional keys with fingers. When you use it, you only need to put your finger flat on the collection window of the fingerprint collector to complete the unlocking task. The operation is very simple and avoids other access control systems (traditional mechanical locks, combination locks, identification Cards, etc.) may be forged, misappropriated, forgotten, deciphered and other disadvantages. The form of fingerprint verification makes it almost impossible for the thief to get started, because the "key" used by the user is his fingerprint. If the thief wants to enter the room, unless he has exactly the same fingerprint as others, it is almost impossible.
However, the so-called Need for Thieves has its own advantages. In the face of the fingerprint access control system, some people made fingerprint copies with silicone to impersonate the identity of real users. This trick even directly provides inspiration for people in the workplace to use fingerprint membrane sleeves instead of punching cards.
3D fingerprint recognition makes access control more secure
As fingerprint recognition technology changes from traditional 2D recognition to 3D stereo recognition technology, it indicates that users have higher expectations for the security and function of the access control system. Compared with planar optical fingerprint access control, 3D fingerprint access control has a greater advantage in recognition rate.
3D living fingerprint recognition makes the access control system more stable, because the recognition problems caused by abnormal user fingers will be greatly reduced. The access control system has better recognition ability for acquaintances. Can adapt to different types of fingerprints under different skin conditions. Users do not need to worry about fingerprints being unrecognizable due to broken or dry fingers. As long as the authority fingerprint is collected in advance, you can enjoy the efficient fingerprint access control function under any circumstances. The fingerprint recognition device can maintain a high recognition rate of at least 5 years or more, and will not suffer from poor response due to continuous use. As the administrator of the fingerprint access control system, you can check the use status of the access control system at any time through the computer and grasp the information of the personnel entering and exiting.
The function of the fingerprint access control system is also reflected in the blocking of strangers, that is, non-authorized persons. The access control system plays the role of access control. One of the important factors is to prevent strangers from entering the access area at will. In the ordinary optical fingerprint recognition system, strangers may use artificial fingerprints to achieve the purpose of entering the access control area. This is because the artificial fingerprint replicates the fingerprint patterns of others and becomes a highly realistic replica.
The optical fingerprint reader cannot distinguish whether it is a real person fingerprint or a fingerprint copy. The feature of 3D fingerprint access control system to eliminate strangers is more prominent, because it has the characteristics of living identification, which can eliminate all non-living fingerprints without being recognized. This advantage will completely eliminate the possibility of maliciously making fingerprint membrane sleeves and entering private areas to ensure the safety of users.
Biometric technology has always been a competent assistant in the field of security. Fingerprint access control system is a typical embodiment of biometric security application, and gradually popularized. Not only because of the user's anti-theft needs, but also because citizens' awareness of privacy is increasing. The access control system has various forms, but the core function is still anti-theft. The traditional swipe card-type access control, the verification method is negligent, and the prevention is not strict enough to meet the needs of users, so it is gradually eliminated. The newly developed 3D fingerprint access control system has a more comprehensive design, which makes up for the deficiencies of the traditional access control system from different angles.
Community families, as the most important harbor for people to rest and recuperate, must have a safe and comfortable living environment. Therefore, in the application of access control technology, the application of more reasonable and efficient identification technology in the community will become more popular.
Outdoor Garden Light is typically used to illuminate areas such as gardens, lawns, pathways, and courtyards. They can be pole-mounted, wall-mounted, or ground-mounted and typically use LED or other energy-efficient bulbs to provide efficient lighting. Outdoor Garden Lights can also be equipped with sensors to automatically turn on or off when detecting people or animals, saving energy and increasing safety. Additionally, they can have different designs and colors to meet various outdoor design needs.
