1）Client-end - collection, transmission

◆Client-end Work Principle
　　

 Client-end is composed of hardware system, software system, transmission system, and protection system.

Front-end video capture terminal module transmit the on-site real-time information to video receiver module through the anti-strong electromagnetic interference signals. In the video receiver module, through S interface and PCI bus interface complete the signals conversion between simulation video signal and digital video signal. Digital video signal are centralized optimization to meet the lossless transmission on Internet. For information security, we use the tunnel encryption, authentication and firewall technologies to ensure the data confidential transmission.

2）Center-end – receive, monitor

◆Center-side Work Principle

Center-end is composed of transmission system, software system, hardware system and support center.
　　

 Network routing modules send the client-end signals back to the center after optimization by the best transmission path to reach security center transmission unit. After decryption and safety certification, submit the information to the central server to integrate redistribution. After completing process, the information transmits to the exclusive display workstation, realizing professional engineers providing 24-hour support services to customers.
