Types and characteristics of entrance and exit management system

Password keyboard type entrance and exit management system

Details: The password keyboard system can be divided into three types: Compact, Switch and battery. The Compact type is to design all control circuits and memories on a keyboard, which can directly power and electromagnetic lock to form a control system.

Switch type is to design the control circuit and the memory on the controller, separate from the password operating system, the keyboard must be connected to the controller in order to be able to process information, and form a control system.

The battery type is a system in which the controller can directly operate with battery power without external power supply, eliminating the need for wiring, easy installation, and battery supply and demand can reach 3-5 years.

The password keyboard can be divided into ordinary membrane key type and stainless steel type in appearance structure. Keyboard programming, simple installation, can be connected to 12V DC or AC, and can also be connected to a backup power supply.

The wiring of the keyboard is sealed. If you press the wrong key 20 times in succession, the system will automatically disconnect for 15 minutes. Available in black, brass, chrome and stainless steel.

Credit card entry and exit management system

The card-type system is divided into two types: Compact and Switch type. All control circuits and memories are designed in the card reader and can be directly connected to the power supply and the electromagnetic lock to form a control system.

Switch type is to separate all the control circuits and memory from the card reader. It is designed on the controller. The card reader must be connected to the controller to handle it.

Card-based applications are divided into management cards and user cards. All management functions are set by the management card.

Induction entrance and exit management system

The inductive exit management system includes a card reader, a controller and an inductive card. The inductive card includes a management card and a user card.

When the system is working, the card reader continuously sends out low-voltage wireless signals. When the card is within the wireless signal energy range of the card reader (40MM), it will receive the signal. There is a silicon microprocessor in the card. Recognize this signal, if it is correct, it will generate a signal (the only password) back to the card reader, the card reader then sends this signal back to the controller to control all connected devices, the induction card does not need The power supply, all the energy required for processing signals and transmitting signals are provided by the radio waves emitted by the card reader.

The system is beautiful in appearance, sturdy, and has excellent waterproof performance. It is IPX7 grade, with a large capacity, and can reach 10,000 users.

Access network management system NETWORK

NETWORK provides a simple and easy-to-use and powerful network access control system design and manufacturing world trends.

Most access control systems are extremely complicated. Installers need to spend a lot of time learning how to install, debug and maintain. Users spend a lot of time learning to use management systems. In most cases, many functional programming is not used, because users have to ask for the assistance of the engineering installer to support the basic system operation.

NETWORK is a system specially designed for the above problems. It can be run on a PC by similar to other standard office software PAXTON AC-CESS FOR WINDOWS 95 software. The software has a friendly interface, powerful functions, detailed online help, and general users. It can be used within 1 hour.

PAXTON ACCESS FOR WINDOWS 95 system consists of software CD, communication interface, desktop card reader, standard S232 cable, etc. The preparation is extremely simple.

NETWORK system can be very convenient to monitor and manage users and doors. User registration and cancellation, user lost IC card, file processing is no longer a troublesome thing, each event is stored in the form of database files, query, Printing is extremely convenient, the software has good compatibility, and it also provides advanced space area and time period management.

The NETWORK system has advanced intelligent functions. It can program and control all access points at any entrance and exit. It can easily achieve central control and rapid signal transmission. Even if the remote entrance and exit are controlled, there will be no transmission delay and network congestion.

The NETWORK control unit consumes a small amount of electricity and is powered by a backup battery. In the event of a computer power outage, shutdown, or network disconnection, some control units are interrupted for some reason, and the control unit continues to maintain normal operation under offline conditions. The unit will record and store all events (up to 3000) until communication is restored, which provides a high degree of reliability of the system.

The system has advanced security, and provides three levels of security (users, system operators, engineers), only enter the account number and password accurately to allow access to the system, can restrict the power of different users, and realize regular backup of system data.

Meniscus Cylinder Lens

Meniscus cylinder Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus cylinder Lens is used to increase the focal length of another Cylindrical Lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the cylindrical lens.

Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens.
Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.
