In non-contact biometric technology, face recognition is the most important module. Since 2019, the application of "face swiping" has been widely used. The epidemic has further promoted development. The future will still be an important direction for AI landing security for a long time. . At present, the traditional face recognition difficulties including face rotation, occlusion, similarity, etc. have been greatly improved, which greatly improves the accuracy of face recognition. With the 2D face, 3D face, and multi-spectral face Represented by multiple modalities, each modal has a different collection and adaptation scenarios, data security levels, and privacy sensitivity, etc. The addition of deep learning of big data enables 3D face recognition algorithms to supplement the defects of 2D projection. The ability to quickly identify people's identities brings certain breakthroughs to the application of two-dimensional face recognition. At the same time, the current living body detection technology is being used as a key technology to improve the security of face recognition, which can effectively resist photo, video, 3D models, prosthetic masks, and other fake fraud, and independently determine the identity of operating users. On the one hand, face applications are mainly for traffic hub scenarios, such as airports and stations, and are mainly used for real-name authentication and key personnel deployment control. On the other hand, it is oriented to city-level applications. Through the docking of the Skynet project, a comprehensive actual combat platform composed of front-end camera deployment and back-end identification platform and big data analysis platform is constructed. In the fields of public security and transportation, the level of facial algorithm technology is leading among AI companies, while traditional companies are mainly led by traditional giants such as Hikvision, S4A, and Dahua. With the rapid development of face recognition technology, many innovative applications such as smart devices, online finance, and face payment have become increasingly common, bringing speed and convenience to everyone's life and work. In addition, in the face of the limitations of Facial recognition access control, gait recognition as a representative body recognition stands out from many technologies due to its difficult to hide, non-contact, and non-invasive characteristics, and has become a "dark horse" in the current biometric recognition field. . Gait recognition recognizes the identity of the target through body shape and walking posture. It is a rather complex behavior feature. Body recognition technology does not require human cooperation and can adapt to more common application scenarios, especially suitable for long-distance identity Recognition. At present, several domestic companies have reached a very high level of recognition accuracy. It is worth mentioning that iris recognition technology is also ...

Intelligent security access control technology refers to view collection, transmission, storage, video analysis, and big data processing, as well as machine vision, AI chips, algorithms, image sensing, biometrics (face recognition, iris recognition, fingerprint recognition, etc.), and New technologies such as intelligent video analysis, multi-dimensional data fusion, and big data analysis. From another perspective, a complete intelligent security system mainly includes three parts: access control, alarm, and video surveillance. The new crown pneumonia epidemic can hinder the development of the market, but it cannot stop the progress of security technology. This year, major security companies have intensified the application of technologies such as intelligence, networking, and the Internet of Things. With the development and progress of science and technology, current intelligent security has entered a brand new field. S4A predicts the development trend of smart security technology from data collection, video intelligent analysis, biometrics, data intelligence, and parts, and other technologies based on actual product measurements. Multi-modality is the development direction of biometrics In the artificial intelligence technology system, biometrics is the first technology to enter the application.  Biometric Access Control Systems recognition technology involves many basic sciences and innovative application technologies such as computer science, optics and acoustics, biological sciences, biosensors and biostatistics, security technology, and artificial intelligence technology. It is a complete multidisciplinary Technical solution. Human characteristics currently available for identification include physiological characteristics such as fingerprints, iris, face, palm prints, veins, and behavioral characteristics such as gait, handwriting, and voice. Biometric identification technology has many advantages such as good security, not easy to lose, difficult to counterfeit, and convenient to carry. It is undeniable that from fingerprint authentication, palmprint recognition, finger vein recognition to face recognition and iris recognition, biometric recognition technology is becoming more mature, but it is also entering the "visual" era. Fingerprint access control recognition is the most "traditional" biometric technology. It has a special status. Compared with face recognition and voiceprint recognition, its recognition accuracy and discrimination are much higher. It can even be said that fingerprint recognition is used in many scenarios. The only feasible way. Starting with a major breakthrough in fingerprint recognition technology in 2018, it has more efficiently promoted the transformation of national social public services and business models. However, with an epidemic in early 2020, the application of non-contact access control technology has been highly valued and developed. Palmprint...

What should we take for the Door Closer? Hold open or Non-Hold open? Door closers form an integral part of commercial door hardware to fire exit doors.  Normally fitted as concealed overhead door closers or face fixed closers, they perform the function of controlling the closing action and closing speed of the aluminum door. Door closer selection will largely depend upon the size of the door leaf in question, the weight of the glass, and the force of the closer, These door closers will also need to be specified as either hold open or non hold open. What is a hold open and non hold open closer? A non-hold-open closer does not keep the door open. Once it is opened past the 90degree point it will commence the closing action of the door.  A hold-open closer is designed to hold the door open when the door is opened past 90 degrees. Simple pushing of the door towards the closed position activates the closer and it also commences the closing action of the door. Do aluminum fire exit doors require to hold open or non-hold open closers? There is no hard and fast rule regarding whether a hold open or non hold open closer is required to fire exit doors. The correct type of closer will largely depend upon the intended function of these doors.  Some aluminium commercial doors that are purely emergency exit doors may remain shut for long periods of time until an emergency escape situation occurs.  Other doors designated as fire exits may still be used by users as entry and exit doors. A hold-open closer may be suitable where a building has a large number of users and the doors will be required to stay open in an emergency escape situation. In buildings where the doors are used as entry and exit doors consideration should be given whether these doors are required to latch shut every time.  The non-hold open closer will ensure that the door leaf closes every time, therefore in these situations, the use of a non-hold open closer may be preferable. Hold open and non-hold open closers are not just for emergency exit doors. Many aluminum commercial doors are used in apartment buildings fitted with an electric release or access control system so residents can gain entry into a building.  Security is the key consideration with these types of doors and in most cases to keep the building secure, they will be required to latch shut every time.  These types of doors should be specified with non-hold open closers. Other types of commercial doors may serve many other functions. Some shops like to leave their doors held open during opening hours.  Other doors may be used used to move items in and out of buildings.  Where the doors are regularly required to be kept open for any length of time, hold open closers are ideal. The correct door closer will largely depend upon the function of the door and how the building is used.  Should a building come under new ownership ...

How to get technical support for access control from S4A? We- S4A Industrial Co., Limited welcome any technical questions for access control.But how to get access control system support in the correct way is very critical. You might ask us, hey, S4A, we are a new learner for access control. We do not know how to ask either. In this case, there is a very simple way, thus, making a video to show the access control problems clearly. We believe when you ask S4A sales questions for access control. All of our sales engineers is glad and responsible to help you immediately, while if you can do the following steps. issues-solving speed will be increasing. Access control is concluded into a standalone access control system and network access control systems. For both systems, we can do self-checking by following the below steps: Step1: Reading the user manual, and check if all wires are correctly connecting, those basic wires connection for access controller is as below: The red cable is 12VThe Black cable is GNDThe white cable is D1The green cable is D0NC / NOCOM These are basic wires which are enough for testing.D1 D0 is signal cable for wiegand26 or wiegand34 You can see a wiring diagram for 90% standalone access control systems:1. When swipe cards, there is no data come out in the software Solution: check if wires all connect right or not.If the wires connection is correct, the next step is to test in software: swipe a card, and you can see in software as below:it will advise you of the exact problems on the right side. Then we can make corresponding adjustments.PS: If you use a standalone access controller as a reader, and we are unable to set reader mode.You will need to register twice before working. 1. Access Controller working with UHF reader When the UHF reader works with access control steps, and we can not open the barrier gate/Lock.Then you need to do 4 steps too: 1.Just power on the UHF reader and swipe cards/labels to see if it works correctly or not.2.When we can hear beeps, Check if the UHF reader output changes to wiegand26 or not.3.If yes, Connect the card reader WG to the control board, swipe the card, and see if the light will flash or not.Here, we can also see software tips too.PS: UHF reader connect to access control board is: 12V GND D1 D0If its flashes mean it is correct. if not flash, means UHF reader PCB has issues now need to send back to detect. Therefore, If you have any questions or compliant, Pls do not hesitate to email back or call us. For example: When we are writing this article, one of the cooperated clients ordered GTP-F1, Fingerprint Guard tour probe and he said: We checked the ERP list and he ordered in June 2015. then we replied it in this way: Pls connect the device to software, and do to communication ->Fingerprints -> then follow this picture to finish 3 steps  1.
