Network access control systems for Hotel management
Network access control systems for Hotel management

The hotel management network access control system is developed and designed by S4A in conjunction with the hotel industry. Its working mechanism is a Mifare card reader installed at the door of each room. When a guest checks in, the Receptionist will send the room number, check-in time, and check-out time through the card issuer (PCD-122 or MCI-109). Enter it into the software of the management, and authorized the cards according to the time and date then upload it to the control host. After the guest arrives at the door of the room, swipe the card on the card reader, it will read the ID number of the card and uploads it to the controller for permission confirmation, and then controls the electric lock to open the door, otherwise, the door cannot be opened. At the same time, the controller saves the door opening information. If the main console is in a "real-time" state, it will be transmitted to the computer control center at the main station via TCP communication, and the door opening information will be displayed on the computer in time. Such as a certain guest, certain time, opening a certain room, etc. The inductive IC card access management control system (referred to as the RFID access control system) has multiple functions such as door access control, real-time monitoring, attendance records, and security alarms. All these functions, you might check it via S4A access control software, It is mainly convenient for staff to enter and exit, and to prevent unauthorized staff to enter, which is convenient for management for all users.

Six application areas of Door access control systems
Six application areas of Door access control systems

1: Office Building The installation of access control in the company gate can effectively prevent outside salesmen from entering the company and disrupt, and it can also effectively prevent outsiders from entering the company, ensuring the safety of the company and employees' property. It Can effectively track whether employees leave their posts without authorization. The attendance can be checked through the supporting attendance management software, without the need to buy a clock, the attendance results are more objective and fair, and the statistics are fast and accurate, which can greatly reduce the work intensity and workload of the personnel department. It can effectively solve the problem that some employees have to replace the door key for fear after leaving. You can conveniently and flexibly arrange anyone's authority and opening time for each door. You only need to take a card, without taking a large number of heavy keys, and the security is more reassuring than the keys. 2: Application of access control systems in the Community Generally, access control systems are installed on residential gates, fence gates, electric doors, iron doors, fire doors, and anti-theft doors of units. (you could choose locks for indoor use or outdoor use if, for outdoor, we recommend to take EL-W600 280KG IP65 waterproof version), It can effectively prevent idle people from entering the community, and conduct closed management of the community. It can change the inaccurate and imprecise management method of the community security who rely on memory to determine whether it is an inaccurate and inaccurate management method by outsiders. If it is a community owner, the new security guards will cause disgust from the owner. If outsiders are well dressed, the security guards may think they are the owners and do not interrogate them. This will also bring about safety hazards. A safe and scientific access control system can improve the quality of the property and is more conducive to developers to promote real estate. Owners will also benefit from scientific and effective access management. The networked access control facilitates the security to monitor the entry and exit of all gates at any time. If there is an accident or case, the entry and exit records can be inquired to provide evidence afterward. It can be combined with building intercom system and video intercom system. It can realize the all-in-one card with the internal consumption parking lot management of the community. 3: Application of access control in government offices It can effectively regulate the office order, can prevent illegal personnel from attacking government offices, and protect the personal safety of leaders. 4: Application of access control in the medical hospital system It can prevent outsiders from entering the infected area and precision equipment room. 5: Application of access control in telecom stations and power supply bu...

Application of RFID technology in the field of fire protection
Application of RFID technology in the field of fire protection

With the rapid development of urbanization in cities, large-scale construction of buildings, a large number of people entering and exiting activities every day, electric vehicles in the community, and the safety of residents' electricity use, fire safety is a very important concern. In a complex social environment, how to improve, innovate, and scientifically manage management models must make full use of various advanced scientific and technological means to enhance the service concept and quality of fire protection work. With the continuous advancement of science and technology, the gradual development of technical and hardware conditions, the rapid expansion of industrial scale, and the vigorous supervision of relevant departments, smart firefighting has emerged. Smart firefighting refers to the use of the Internet of Things, big data and other technical means to organically link firefighting facilities, socialized firefighting supervision and management, firefighting and rescue and other elements through Internet of Things information sensing and communication technologies to achieve real-time, dynamic, interactive, Integrated fire protection information collection, transmission and processing, comprehensively promote and improve the level of fire supervision and management, enhance the command, dispatch, decision-making and disposal capabilities of fire fighting and rescue, improve the intelligent and social level of fire management, and meet the "automation" of fire prevention and control , The actual needs of "intelligence" fire fighting and rescue command, "systematization" of daily law enforcement work, and "refined" military management, realize smart prevention and control, smart operations, smart law enforcement, and smart management, and create a "firewall" from the city to the home . Smart firefighting uses RFID technology to scan tags for daily fire prevention inspections by posting encrypted RFID radio frequency tags and establishing ID cards on key firefighting parts and firefighting facilities of the unit. In addition, the system will automatically prompt the inspection standards and methods of various fire-fighting facilities and key parts, and automatically record the inspection traces of inspectors, replacing the traditional paper inspection records. It has changed the status quo that traditional fire prevention inspections are not in place and inspection records are untrue. The maintenance and inspection of fire-fighting equipment is a major foundation of smart fire-fighting construction.

The Solution for the Prison access card system
The Solution for the Prison access card system

With the development of access control systems, the one-card system is applied in more and more places. Recently, the access control card system also was widely used in the digital prison security system. Traditional card systems often have many security hazards in the complex security environment of prisons. How to eliminate these security hazards is what we have been doing.The prison card system generally consists of access control, attendance, patrol, and meeting management. Due to the particularity of the prison security environment. Here are some hidden dangers of traditional card systems: 1. Access control managementPrisons are places where prisoners are concentrated, so access control management has become a key part of prison security. Conventional access control functions have problems in some special situations.1)How to solve the security loophole at the prison gate?Between one gate (gate A) and the second gate (gate B) of the prison is the isolation zone where the prisoner contacts the outside world. If the two gates are open at the same time, the isolation zone loses its "isolation" function. It left hidden dangers for prisoners to escape. 2) How do prison guards respond when they are being held hostage?In prisons, when prisoners escape, they will often hold the guards and open the door to escape. In the face of this situation, how can we not only ensure the personal safety of prison guards but also promptly notify the staff on duty and activate emergency plans is a problem we must solve. 3)How to link with monitoring and alarm to keep safer?Access control is a part of prison security. It is obviously not enough to complete its own access control function. It must be well linked with monitoring and alarm to make access control management play a better role in security prevention. 2. Patrol management-how to ensure real-time data Traditional offline patrol data cannot be uploaded in real-time, which simply cannot meet the requirements in the prison security environment. The prison requires that patrol data must be uploaded in real-time, and at the same time, when the patrol fails to reach the designated patrol point due to an accident, an alarm must be issued to alert the duty officer. 3. Family meeting management-how to accurately verify the identity of family membersFamily meeting management is the window for prisoners to contact with others, and the security of the meeting must be ensured. Therefore, the identity verification of "family members" is particularly important. S4A access control's prison all-in-one card system solution In order to ensure the advancement and safety of the prison all-in-one card system, S4A access control's prison all-in-one card system has been specifically designed for the security environment of the prison. S4A access control integrates access control management, real-time access control records, and perimeter alarms. Eliminate the...

National Holiday in Oct,2020-S4A INDUSTRIAL CO.LIMITED

S4A INDUSTRIAL CO.LIMITED-National Holiday in Oct 2020FromToTotal Holidays1st, Oct 20208th, Oct 20208DaysWe will resume work on 9th, Oct 2020, During this time, if you have any questions, pls call us at +86 755 29450011 Chinese National Day in China in 20202020 brings a bumper break for National Day and Mid-Autumn Festival with the holidays starting on October 1st and lasting until October 8th. Two of the holidays will be compensated by working days on Sunday, September 27th, and Saturday, October 10th.When is Chinese National Day?The People's Republic of China (PRC) observes its anniversary on October 1st. China's National Day has been celebrated in various ways during the history of the PRC.In China, the holiday is officially three days, but the holidays are usually extended by bridge holidays compensated by working on weekends depending on how the holiday falls in the week. This creates a so-called 'Golden Week' of holidays. This makes it the second-largest holiday period in China. This approach was introduced in 2000 to help boost domestic tourism and to allow families to make long journeys to visit relatives, though unlike most Chinese holidays, National Day doesn't come with any obligations to visit your family.In 2019, about 782 million people traveled during the National Day holiday, with 30.5% doing so by car, according to the Ministry of Culture and Tourism.History of Chinese National DayOn October 1st, 1949 Chairman Mao Zedong proclaimed the founding of the People’s Republic of China from atop Beijing's Gate of Heavenly Peace (Tian'anmen Gate).This marked the end of a bitter civil war between the Chinese government and the Chinese Communist Party under the leadership of Mao. In December 1949, the Chinese Government passed the Resolution on the National Day of the People's Republic of China, declaring that October 1st is the National Day of China.From 1950 - 1959, grand rallies and massive military parades were held to mark the National Day.In 1960, the Central Committee of the Communist Party of China (CPC) and the State Council decided to simplify the celebration, according to the principle of building up the country through hard work and frugality.From 1960 until 1970, mass rallies were still held in Tian'anmen Square, though military parades were canceled.From 1971 to 1983, visiting parks and other galas replaced mass rallies and military parades.Grand celebrations have been rarely held since then, except for the mass rallies and military parades in 1984 and 1999 to commemorate the 35th anniversary and 50th anniversary of the founding of the PRC.Most people believe that countries' national days are of crucial cultural importance, acting as symbols of independent states and reflecting a country's government system.
