How does fingerprint access work 5

The fingerprint recognition system is a typical pattern recognition system, which includes modules such as fingerprint image acquisition, processing, feature extraction and comparison. Fingerprint image acquisition: Fingerprint images of living individuals can be collected through a special fingerprint collector.

At present, fingerprint collectors mainly include in vivo optical, capacitive and pressure-sensitive. For technical indicators such as resolution and collection area, the public security industry has formed international and domestic standards, but there is still a lack of unified standards. According to the area of fingerprint collection, it can be roughly divided into rolling fingerprint and plane fingerprint, and the public security industry generally uses rolling fingerprint.

In addition, fingerprint images can also be obtained through scanners, digital cameras, etc. Fingerprint image compression: Large-capacity fingerprint databases must be compressed and stored to reduce storage space.

The main methods include JPEG, WSQ, EZW, etc. Fingerprint image processing: including fingerprint area detection, image quality judgment, pattern and frequency estimation, image enhancement, fingerprint image binarization and refinement, etc.

Let's go to Fly-in E-Consultation.

You can use the new finger vein recognition technology launched in China, 80% of ATMs in Japan are equipped with vein recognition devices instead of passwords, you can see domestic products in the W2 hall of this year's security expo, I hope it will help you!

The working principle of fingerprint access control is to form a complete access control system with other access control accessories, including fingerprint host, access control power supply, magnetic lock, exit button, door clamp. , brackets, etc. %@

For the entrances and exits that need to be controlled, install electric lock devices and sensors (such as: electronic password keypad, card reader, fingerprint reader, etc.) to control the electric control door; Authorized personnel can open the electric control door with a valid card, or password and their own fingerprint; All access data are recorded by the background computer; Through the background computer, the access permission of authorized personnel can be modified at any time; The system can also incorporate time and attendance system features.

Introduction: Everyone's fingerprint is unique, now many security products are gradually integrated into the design of fingerprint elements, fingerprint access control is a good product, can directly control the opening of the door through fingerprint identification, greatly improve the security of anti-theft. What are the fingerprint access control brands?

You can take a look at the following introduction, when choosing fingerprint access control products, it is also recommended that friends choose brand products, so as to get more stable technology.

Fingerprint access control brand is very much, the following for friends to make some brand recommendations, in the choice of fingerprint access control friends is best to choose the development and design of the company's products, so as to have a more core technology, in the use of more perfect protection, to avoid the quality or use of the problem can not be solved.

Fingerprint access control brand recommended keylock: this brand is a very well-known American high-end brand, which has a very strong security performance, the market share is not high, can meet the requirements of scientific and technological furniture, and it is also very convenient to maintain when there is a problem.

Fingerprint access control brand recommendation of Desman: This brand adopts the design concept of Bauhaus, not only the quality of the product is very prominent, but also very good in terms of appearance, friends buy this brand of fingerprint access control is not only a security aspect and consideration, but also has a certain art collection value.

Fingerprint access control brand recommended socks leather staring Yajie: This brand was established in 1990, covering not only bathroom products and hardware products, but also drawers and sliders. The quality of fingerprint access control is very good, which can meet the better use effect, and when there is a problem, friends can also get good maintenance services, and the fingerprints of family members can be added when designing fingerprints.

Fingerprint access control brand recommended three-ring lock: this brand of products is very good, now it is a large enterprise of civilization at home and abroad, the product has added more intelligent factors, can meet the requirements of home security, friends do not have to take into account the security issues.

The above is the fingerprint access control brand recommendation, friends can refer to it when purchasing, the general fingerprint access control ** in more than 1000 yuan, if it is too cheap products are not recommended to choose friends, because the quality of fingerprint access control is directly related to security, too low ** product quality will inevitably decline.

As the name suggests, the access control fingerprint machine has the function of access control, which can be used as access control, and the system can also take data from the access control fingerprint machine for attendance analysis, but the access control has certain limitations in attendance, and the attendance analysis is easy to be inaccurate.

The punch fingerprint machine is an attendance machine that is specially used for attendance, and the attendance data analysis is accurate and clear.

Both are fingerprint machines, and both have the function of punching in and out.

One does not have an electric plug lock signal output, and the punch card fingerprint machine does not have an electric lock signal output.

The access control fingerprint machine is to increase the personnel grouping, week, and time period to be controlled (so that you can control the authority of the personnel period).

If the requirements are relatively simple, you can directly use a punch card machine with an output signal.

To put it simply, it is the difference in function, the access control fingerprint punch card machine has an access control function, which can be used for access control.

The access control fingerprint machine is basically the same as the punch card fingerprint machine, but the performance of the access control is much better.
