Access Control systems with Pedestrian turnstile gate application
Access Control systems with Pedestrian turnstile gate application

The use of access control systems in life has gradually become widespread, and different types of access equipment are required in a different entrance and exit scenarios. For example, three roller gates and turnstiles in stadiums, pedestrian passages in campuses, enterprises, and high-end intelligent buildings. While they effectively help the staff to reduce work pressure, they also ensure the safety of traffic.   Access control gate system has the following five advantages:   1. Simple and easy to use. Existing access control management personnel only need to go through simple training to be able to operate. The maintenance personnel of the access gate can find the fault in a few simple operations, which can be quickly and conveniently eliminated.  2. Advanced technology. Using the most popular wireless network management system at present, the channel gate ensures that your management system will not lag behind in ten years.   3. Low overall cost. From the perspective of installation, debugging and wiring, the use of TCP/IP transmission can reduce a lot of investment. In addition, the construction period is short, which saves wire and labor costs, and is very easy to maintain. Therefore, the use of access control gate system, More advantages in cost.   4. There are many uses. The channel gate management system uses a non-contact smart IC card, also known as a radio frequency card, which successfully solves the problems of multi-use, confidentiality, wear-free, and easy operation of the IC card greatly improves the practicability of the system and can perform a single card After multiple authorizations, the channel gate can be used for other application management. Such as attendance, consumption, parking management, patrol, personnel.   5. Convenient expansion. The computer and the intelligent management system adopt wireless communication, and the channel gate can expand the number of channels at will. That is, when the corresponding control system is installed, if the number of intelligent access gates and elevator control equipment needs to be increased, the hardware only needs to increase the corresponding access gates, and the software can set the new equipment.Three influencing factors of the access control system:  As an intelligent access control system, its much more complicated than traditional access control unit. Naturally, there are more factors affecting its functions. There are three main aspects in a simple understanding:  1, design styleHigh-end pedestrian passages need to integrate product safety, modern, and concise design concepts with the building environment and architectural style; the line is mainly streamlined, reflecting the concise and comfortable style, and the material is more glass and stainless steel. The stylish and transparent design of the company is consistent with the construction style of intelligent buildings; and the high-end pedestrian walkway products have obvious differences in metal surface processing...

What's kind of sensor we are using for the Automatic Door opener?
What's kind of sensor we are using for the Automatic Door opener?

What's kind of sensor we are using for the Automatic Door opener? Active Infrared Functional Principles: An Active Infrared Detector always consists of one transmitter and at least two receiver chips with high-quality optical systems. The scanning range is set by means of a mechanical micro-speed unit by changing the angle between the transmitter and receiver. This optical procedure is called triangulation or optical differential measurement. Active Infrared Detectors are static—they only detect persons and objects if they break the beam. The detection area consists of spots, and depends to a large extent, on the optical center-to-center distances of the transmitter and receiver lenses. Several beams can be combined in a modular system to form a larger area. Choose from: Background suppression presence detectors are used on moving parts like a swing door or revolving door. This system does not require a background like a wall or floor. Background analysis requires a signal from the background in order to switch the output. The sensor is installed and requires a background (floor/wall). The output is deactivated.The desired scanning range is set mechanically within the predefined possible distances.Each object within the set scanning range is detected statically.Passive Infrared Functional Principles: Passive Infrared Sensors function in a similar way to infrared cameras used to detect heat loss from buildings. The infrared-sensitive sensor forms a heat image of the defined area to be monitored. After an initial set-up time of approximately 20 seconds, the measured infrared image is saved. The sensor switches if the heat image changes as a result of movement. Two conditions must be fulfilled here: 1. There must be a temperature difference of +/- 1.8 F between the object to be detected and the background.2. The object to be detected must move at a rate of at least 4 inches per second. The system is ideal for detecting people only if— there is always a difference of at least 1.8 F between the surface temperature of a clothed person and the surrounding environment. For reasons of a physical nature, this technology should only be used to detect living beings as it’s not always possible to guarantee that the difference in temperature between items such as shopping carts or vehicles, and that of the surrounding environment will be great enough. Microwave sensor ( we have 2 models are available to choose, M204 and M204-T)So, we need to know first what is a Microwave Motion Sensor?A microwave motion sensor uses electromagnetic radiation. It emits waves that are then reflected back to the receiver. The receiver analyzes the waves that are bounced back. If there is an object moving in the room, these waves are going to be altered. The microwave detector is able to identify changes from moment to moment. Ideally, the receiver should be receiving the same waves back again and again.Beca...

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...

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.Author: Written by Mr.Andy Zhang from S4A INDUSTRIAL CO.,LIMITED
