Some are even talking of a doubling. Delivery times for European steel producers are already six months or more. – so at least in August.Market safeguard measures pose problems for the processing industryWhat is currently bringing the review of the Safeguard measures by the EU Commission and the political events surrounding it into focus in the steel world. There are now strong calls from the processing industry for an end to Safeguard.United States with all-time highs for steelSteel prices in the United States are also reaching new all-time highs and availability is more than limited. The economy in the United States has rebounded and market sources told us that things are currently going crazy there and there is hardly any material to be had.South America also feels the rising prices,In South America, the consuming industry complains of the same suffering. Severe shortages. New material is not yet in sight. And prices are rising sharply. In between, one hears voices from time to time that want to talk down the problem. But at the moment, domestic steel producers are completely overwhelmed and cannot keep up with demand.What about stainless steel imports from Asia?“Imports from Asia would currently be an alternative for many companies. But here, too, it is currently a question of readiness to make decisions and speed. And the right knowledge about where to get material and how to import it properly.The supply chain has not yet returned to normalThe supply chain to and from Asia has not yet fully recovered. There are still not enough containers available where they are needed. The shortage of ships and containers is also reflected in the price. Ocean freight rates have increased eightfold in some cases (European mills significantly increase alloy surchargesAlloy surcharges are up significantly again for March 2021. Looking at Outokumpu’s alloy surcharges for 304 from November 2020 versus March 2021, they have increased by almost 28% (about 54 US cents).

With the rapid development of China's economy, people's attention to security issues has prompted the rapid development of China's security industry market. The social security situation caused by the process of economic development is also worrying. The ever-widening gap between the rich and the poor has caused the crime rate in developing countries to rise, and the demand for controlled access systems in society is also increasing.At present, the integration of entrance and exit systems with monitoring, anti-theft alarm, and intercom systems is the general trend, and the boundaries of the four security systems are becoming more and more blurred. The four security systems all rely on computer software integration platforms, including access control and parking lot management systems. The integration of the entrance and exit system and the intercom system also started.If you want to check the demo software,pls contact S4A right now!The access control system and the parking lot system are collectively called the entrance and exit control system. As the name suggests, it is a system that controls the entrance and exit passages. Where to let certain people, refuse certain people, when to sound an alarm, and remember the process of entering and exiting to achieve control Security purpose. It is developed on the basis of traditional door locks. The traditional mechanical door lock is just a simple mechanical device. No matter how reasonable the structural design and how strong the material is, people can always open it by various means. It is very troublesome to manage the keys in the passages where a large number of people enter and exit. If the key is lost or the personnel are replaced, the lock and key must be replaced together.In order to solve these problems, the emergence of electromagnetic locks and electronic code locks has improved people's management of entrances and exits to a certain extent and made the management of channels enter the electronic age. However, with the application of these two electronic locks, Their own defects are gradually exposed. The amount of information stored by the magnetic stripe is small, the contact card and the card reader are worn out, and the failure rate is high. The problem with the magnetic card lock is that the information is easy to copy and the safety factor is low.In recent years, with the development of proximity card technology and biometric technology, the access control system has developed rapidly and has entered a mature period. Induction card access control systems, fingerprint access control systems, iris access control systems, and finger vein recognition access control systems have appeared. , Face recognition access control system, out-of-order keyboard access control system, and other technical systems, have their own advantages in security, convenience, ease of management, etc., and the application fields of access control systems are becoming wider and wider. As the usage...

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 ...
