Everything You Should Know about Face Recognition Access Control

December 03,2021

With the continuous development and innovation of technology, more and more smart products are applied to our lives, making our lives more and more convenient. Among them, one of the most impressive is the biometric smart lock. After all, everyone has the experience of forgetting to take the key and being locked out, right?


Imagine that, without a key, only a fingerprint, voice, the face can open the door, which can save your time tremendously. Simply put, your house is safe as long as you are safe. You no longer have to worry about thieves breaking into your house at any time, excellent?


There are many kinds of biometric smart locks on the market now, including fingerprint locks, face recognition locks, pupil recognition smart locks, and voice recognition smart locks. Today, we mainly focus on face recognition access control from several aspects.


Face Recognition Access Control


What is the principle of face recognition access control?


A regional feature analysis algorithm widely used in face recognition technology, which combines computer image processing technology with the principles of biostatistics. It uses computer image processing technology to extract facial feature points from videos and analyzes and establishes the principles of biostatistics, that is, a facial feature template. Use the built-up face feature template and the face image of the subject to perform feature analysis, and give a similar value based on the result of the analysis. This value can be used to determine whether it is the same person.


What are the merits of face recognition access control?


As a new type of biometric recognition technology, face recognition has unique advantages in applications compared with iris recognition, fingerprint scanning, palm scanning, and other technologies:


Easy to use and high acceptance. Face recognition technology uses a general-purpose camera as an identification information acquisition device to complete the recognition process in a non-contact manner without the recognition object being noticed. The human face is undoubtedly the most intuitive information source that can be discerned by the naked eye, which is convenient for manual confirmation and auditing.


The recognition accuracy is high and the speed is fast. Compared with other biological recognition technologies, the recognition accuracy of face recognition technology is at a higher level, and the false recognition rate and rejection rate are lower.


Not easy to counterfeit. On occasions with high-security requirements, face recognition technology requires that the recognition object must be on the scene, and it is difficult for others to imitate. Its unique active discrimination ability ensures that others cannot deceive the recognition system with inactive photos, puppets, and wax figures. This is difficult to achieve with biometric technology such as fingerprints.


Use universal equipment. The equipment used in face recognition technology is ordinary PCs, cameras, and other conventional equipment. Since computers and closed-circuit television monitoring systems have been widely used, most users do not need to purchase a large number of special equipment to use face recognition technology. This not only protects the user's original investment, but also expands the functions of the user's existing equipment, and meets the user's security requirements to some extent.


Easy to obtain basic information. Face recognition technology is based on face photos or faces images taken in real-time, so it is undoubtedly the easiest to obtain.


Low cost and easy to promote. Since the face recognition technology uses conventional general-purpose equipment, the price is reasonable and acceptable. Compared with other biometric technology, face recognition products have a very high-cost performance.


In a word, face recognition access control is a high-precision, easy-to-use, high-stability, difficult-to-fake, and cost-effective biometric recognition technology, which has extremely broad market application prospects.


What are the drawbacks of face recognition access control?


Certainly, every coin has two sides, there exists some drawbacks when using it. Here we go:


Facial recognition is considered to be one of the most difficult research topics in the field of biometrics and even artificial intelligence.


There is little difference between individuals with different similarities. All facial structures are similar, and even the structural appearances of facial organs are very similar. Such a feature is advantageous for using faces for positioning, but it is disadvantageous for using faces to distinguish individuals.


Variability. Humans can produce many expressions through changes in their faces. In different viewing angles, the visual images of the face are also very different. In addition, facial recognition is also affected by lighting conditions (such as day and night, indoor and outdoor, etc.), facial coverings (such as masks, sunglasses, hair, beards, etc.), age, and many other factors.


Power consumption. The power consumption of face recognition is much greater than that of fingerprint locks. A typical fingerprint lock with 6 dry batteries can be used for about a year. The functions of the face recognition lock, such as light supplement, collection, etc., are very power-consuming, so it is best to replace the battery every six months.


Face recognition access control has become a popular trend due to its convenience and practicability. If you can't wait to experience it? Just contact us, we will provide you with the most competitive price.
