What is the Fingerprint Door Lock
What is the Fingerprint Door Lock ?
Locks have been around for more than 5,000 years. We've always used them to keep our important things safe, but before fingerprint locks, we couldn't avoid the embarrassing problem of losing your key and not being able to pick it. The appearance of fingerprint lock completely solves the pain point of being rejected because of forgetting the key and losing the key. A lot of people may have a bias against fingerprint lock, this is an electronic product, talking about security, how can compare to the traditional door lock? In fact, this idea is wrong, fingerprint lock has been considered at the beginning of the design of this problem, and even more advanced technology means to ensure that security is the most important quality.
Now on the market of fingerprint lock is multifarious, overwhelmed, a lot of fingerprint lock on some new features, new look + hype, and other marketing gimmick to gain market, but also should make sure most basic security functions are not ready, personal feel figure something fancy great effort is futile, and improve quality is the most important thing. Fingerprint lock is the most important product quality, stability, after-sales service.
The fingerprint lock panel consists of three main materials: zinc alloy materials, stainless steel materials, aluminum alloy materials. The panel made of zinc alloy has good corrosion resistance and high hardness, which is the preferred material for fingerprint lock panel of major manufacturers.
The fingerprint lock with sliding cover can effectively protect the fingerprint identification module of the fingerprint lock, so that the service life of the fingerprint identification module is longer. But many fingerprint locks aren't designed with a slide cover, because they're easier to unlock. In fact, fingerprint lock without a slide cover as long as you protect the fingerprint identification module, can be used for a long time, there is no need to choose a fingerprint lock with a slide cover.
Fingerprint lock according to the shape of the handle can be divided into push and pull type and press type two, which press type is with a horizontal handle, and the door is the need to press the handle, and push and pull type is to open the door by pushing the handle. Fingerprint lock can also be divided into semi-automatic and automatic two kinds, semi-automatic is generally after fingerprint identification needs to press down or push the handle to pull the lock tongue, and automatic is after fingerprint identification motor will automatically pull the lock tongue, then has been unlocked, directly push the door can enter. Semi-automatic lock door need to lift the handle to lock, automatic are automatic lock, so automatic will be more electricity.
Fingerprint lock mainly has two mainstream identification modules: optical fingerprint identification module and semiconductor fingerprint identification module. The recognition accuracy of semiconductor fingerprint identification module is much higher than that of optical fingerprint identification module, and the rejection rate is low. Now the mainstream brand of fingerprint identification module are using the semiconductor way, semiconductor fingerprint identification module is better used in Sweden semiconductor fingerprint identification module.
Fingerprint locks generally support password input mode in addition to fingerprint identification unlock mode. Better fingerprint locks will have virtual password function. A good fingerprint lock keyboard will use a panel that does not leave fingerprints, to prevent others from cracking long-term passwords. You are advised to change the long-term password of the fingerprint lock periodically for security purposes.
Because the current fingerprint lock is powered by dry battery or lithium battery, it is inevitable that the battery is out of power and the fingerprint identification system fails. Therefore, the fingerprint lock is designed with an emergency power supply port. When the internal power supply fails, the emergency power supply can be used to restart the system. Emergency power outlets are usually designed to be hidden, usually at the bottom of the lock.
Since fingerprint identification systems are not always guaranteed to work, fingerprint locks are also designed to be unlocked with an emergency mechanical key, and will always have a keyhole. Fingerprint lock keyholes are usually designed to be hidden, The emergency mechanical key is used to open a fingerprint lock in the event of a fingerprint failure, and each fingerprint lock is equipped with two or more keys
The design of the anti-lock knob is to retain the anti-lock function of the traditional lock, basically every fingerprint lock will have. It is safer to lock after entering the door. Some automatic fingerprint locks will automatically lock after entering the door, which is very convenient.
The lock body is one of the important components of the fingerprint lock. When buying the lock body, you need to choose the size of the opening of the lock body according to the location of the door. If the lock body is not selected, it may directly affect the life of the lock. The material of the lock body is mainly stainless steel, but there are zinc alloy and iron, it is best to choose 304 stainless steel. The lock body is mainly divided into standard lock body and overlord lock body two kinds, the standard lock body is safe enough, if you want to be more secure, then choose overlord lock body.
The internal circuit design of fingerprint lock is also very particular. Generally, the internal circuit of fingerprint lock of big brands will have overload protection design, which can effectively defend against small black box attack. The black box can unlock poor quality fingerprint locks because it instantly generates a powerful electromagnetic field, overloading the internal circuitry and causing the system to restart to unlock them. So be sure to choose a fingerprint lock that resists electromagnetic interference from a small black box.
The lock cylinder is divided into grade A, GRADE B and grade C, and the safety and the difficulty of prying open increase successively. Now many brands of fingerprint lock are using c-level lock cylinder
The chip inside the fingerprint lock is similar to the CPU of a mobile phone or computer. A good fingerprint identification module needs to be matched with a good fingerprint identification processor to play its advantages, while the internal chip of the fingerprint lock of big brand manufacturers is self-developed or foreign specialized processing chips, with strong performance and high security.
