The most common fingerprint smart door configuration is a standard door lock with a handle. The fingerprint smart lock is composed of components such as the lock cylinder part, the handle, and the lock panel. The cooperation between these components makes the smart lock more intelligent. The following is an introduction to the composition of the fingerprint door lock.
1) Control panel
The control panel refers to the front and rear panels of the fingerprint lock and is the decisive factor in determining whether a buyer likes this lock or not. Because appearance is the most obvious. Metal alloys, stainless steel, aluminum alloys, plastic, and zinc alloys are the most common materials used for smart lock panels. At present, the mainstream panels are made of zinc alloy and stainless steel, which have good corrosion resistance and high hardness.
2) Lock the body
The lock body is mainly divided into two types: standard lock body and non-standard lock body. The main material is stainless steel, but a small part is also iron.
3) Circuit board
The circuit board is the core of the smart lock, which is equivalent to the human heart. It controls the life and performance of the fingerprint door lock.
4) Motor
The motor is the motor that provides power for the fingerprint lock, just like the driver software of the computer. The motor is the connecting device between electronics and machinery, and the center of power conversion. It is equivalent to a bridge and plays an important role in linking the past and the future. When you use your fingerprint to unlock, you will hear the sound of the motor turning once. If the motor stops turning, the lock will automatically open and cannot be locked.
5) Handle
The design of the handle is convenient for people to open the door, and the smart door lock is divided into push-down type and push-pull type. After the fingerprint of the push-down door lock is verified, the lock cylinder of the smart door lock will release the lock tongue through the device, so that the lock tongue is directly connected to the push-down handle of the door lock.
When you press the handle, the lock tongue can be fully retracted. Get up. However, the push-pull door lock does not have the step of pressing down. The lock tongue of the door lock is directly controlled by the internal motor. After passing the verification, the lock tongue will be directly inserted into the interior. You can choose different fingerprint lock handles according to different needs.

6) Keyboard
Ordinary fingerprint door locks are also equipped with a password verification method. The keyboard of a fingerprint lock usually uses the reflection of light to judge the input, but not all smart locks are equipped with a password keypad.
7) Fingerprint sensor
The fingerprint sensor of the fingerprint lock is mainly divided into two types: optical fingerprint head and semiconductor fingerprint head. Optical fingerprint identification is to identify fingerprints through mirror refraction, which has the advantages of durability, easy cleaning, good stability, and low cost. Semiconductor fingerprint recognition is electrical recognition through living skin, and its recognition rate and security are higher than optical fingerprint recognition.
8) Lock the cylinder
The lock cylinder is an important factor in determining the price of a smart lock because different levels of lock cylinders have different security levels. The lock cylinder is divided into three grades: A, B, and C.
9) Battery slot
The battery slot is used to store batteries. The current mainstream fingerprint door locks battery slots are 4 batteries, 6 batteries, and 8 batteries.
10) Anti-lock knob
The anti-lock knob is to prevent it from being opened by bad guys, adding a security line to the house. Basically, all home smart locks will be configured.

11) Slider
The fingerprint door lock with a sliding cover can effectively protect the key unlocking part. Of course, there are also fingerprint door locks without a sliding cover, which should be selected according to the needs of different occasions.
12) Bluetooth module
This is the IoT part of the smart lock. Some fingerprint door locks can be opened remotely by connecting to Bluetooth and wireless networks.
13) Camera
In order to make smart fingerprint locks more secure, many fingerprint locks are now equipped with cameras. The function of unlocking and taking photos can be pushed to your mobile phone, and there is even an anti-staying and snapping function.
