2、 Design principles

In order to establish a sound and light system with advanced technology, stable performance, complete functions and convenient use, our system design follows the following design principles: progressiveness, practicality, integration, scalability, convenience, safety, reliability and economy< Br>
(1) Progressiveness

● The system design is world-class, practical, and easy to implement< Br>
Comply with international standards and relevant domestic and foreign regulatory requirements:

It is in line with the latest development trends of computer, network communication technology, and video conferencing technology, and is a mature system with mature applications< Br>
(2) Practicality

Based on the characteristics of practical applications, there are multiple management methods available:

● The system design meets the actual needs of the project< Br>
● System configuration emphasizes both progressiveness and practicability< Br>
(3) Integration

Highly integrated, small in size, light in weight, easy to move, and low in power consumption:

With high integration and miniaturization, it has multiple functions< Br>
(4) Scalability

Consider future development and leave ample room for expansion< Br>
(5) Flexibility

Being able to adapt to the requirements of multifunctional and outgoing, emphasizing convenience and comfort, achieving the goal of improving work efficiency, saving manpower, material resources, and energy< Br>
● Provide interfaces and tools in software, hardware, communication, network, operating system, data management system and other aspects that meet international standards, so that the system has good flexibility and compatibility:

The system has few parameter configurations, few adjustments, high degree of automation, convenient use, and simple operation< Br>
(6) Security

Has high security and is not easily infected with software viruses< Br>
● Support encryption systems< Br>
(7) Reliability

Having the ability to complete the functions required by users within the specified conditions and time, and able to work stably for a long time< Br>
Simple structure, few connection points, and high reliability< Br>
Low requirements for working conditions and environment< Br>
The system starts quickly and returns to normal after a power outage or network transmission interruption, resulting in a rapid system recovery< Br>
Low failure rate, convenient maintenance and repair< Br>
(8) Economy

Taking into account the performance and price of the system, the cost-effectiveness ratio is optimized under similar systems and conditions, taking into account the following factors for economic efficiency< Br>
● The price of the system itself (including system, technical services, and training)< Br>
● Possible benefits of economic effects budget after system operation< Br>
● The cost required for the special requirements of the system implementation site< Br>
● Development costs related to software and hardware required for system integration< Br>
● Easy expansion of the system.
