What are the advantages of network video surveillance system compared with analog closed circuit system?

The information flow and media flow of the network video surveillance system are digitalized and independent of each other. The hardware and software adopt the design concept of standardization, modularization and scale. The configuration of the system equipment has strong versatility, good openness, flexible system configuration, It has the advantages of perfect control function, convenient data processing, convenient use, and simplified system installation, debugging and maintenance. At the same time, the scale of IP and digital products will bring cost advantages.
