First, strong stability
“Stability†is the first principle of the choice of access control system. The mature products that should be considered as much as possible have passed many authoritative certifications and have many typical users. They have been operating normally for many years and are highly recognized in the industry.
In terms of hardware, the device from the controller to the terminal is a mature and stable product. As the core of the system, the access controller needs to support the offline working mode. It must use a non-volatile memory chip such as flash. The power loss or impact information will not be lost. Server and terminal identification device failure does not affect the normal operation of the system
As the management software supported by the system, it should have a stable and reasonable database structure design, and use real-time polling mode with the hardware to maintain and monitor the hardware communication connection and enquiry, and complete the data integrity, reliability and consistency.
Second, strong resistance to damage
The access control system is used to protect people and property, so the system itself must be safe. The high security mentioned here refers to the natural or quasi-natural nature of the product or system. It should ensure the safety of equipment and system operation and the safety of the operator. For example, the equipment and the system itself must be resistant to high temperature and low temperature. Damp heat, and can prevent static electricity, anti-interference, etc.; on the other hand, access control and security systems should also have the function of preventing human damage, such as: with tamper alarm.
Third, excellent compatibility
In order to facilitate future upgrades, expansions, and anti-interference considerations, it is recommended to select terminal identification devices that meet international standards, rather than the compatibility as wide as possible. Some formats have some advantages in part, but they do not conform to international standards. They will cause troubles for future upgrades, expansions, and anti-interference. They should adhere to the principle of “practical, stable, and standards-compliantâ€.
Fourth, flexible scalability and economy
It is recommended that the registration card permissions need to reach 30,000, which can meet the storage capacity requirements of most customers, and facilitate the attendance statistics and enterprise scale expansion. The main equipment should adopt modular design and adopt advanced wiring method. It can realize future system expansion through software and hardware upgrades, without having to make too much changes to the system, maximizing the economic principle, and the product should be cost-effective.
Five, powerful software management functions
With the wider application range of the access control system, it is required to implement the linkage control function with other systems such as attendance management, security alarm, parking lot control, elevator control, consumption management, CCTV linkage, online patrol, etc., so the system software should have video. Interface and support for extended functionality.
Six, easy to maintain
The system should be easy to install and configure, simple to use, and have a unified network management capability for easy maintenance.
7. Purchase mature brand products at the dealers designated by the manufacturer.
Mature brands can guarantee a perfect service system. This includes two aspects: first, project implementation and thoughtful after-sales service; second, reliable follow-up research and development capabilities to ensure continuity and compatibility between new and old products.
Buying from agents can have reliable quality and perfect service. Buying from other channels may have lower prices, but after-sales service may not be enough.
Eight, product appearance
With the improvement of people's aesthetic standards, while pursuing functional and practical, it can be used as one of the reference standards in order to realize the additional functions of visual enjoyment.
Crimping Curving Machine
The steel sheet can be made into Arch eaves board by crimping curved making machine.
The eave boards are widely used in gardens, factories, storehouses, hotels, exhibition halls, shops, simple architectures and mobile houses.
Color steel corrugated and trapezoid steel sheet crimping curving machine consists of feeding device, curving&pressing device and electric control system. It adopts the formed pressing die to press the [pit" on the formed panels and make the panel curved. By changing the distance of the wave mark and adjusting the depth of [pit" can form into the panels with different radian. This machine adopts the PLC control to realize the automatic controlling of wave mark space and the free-set of wave mark space data.
