NVR Kit China's domestic level
China Telecom's Global Eye and the former China Netcom have developed remote video monitoring in conditional households. For example, the wide view video monitoring business has been launched in China Netcom's Shanxi, Shandong, Jilin, Zhejiang, Henan and other provincial companies in the early stage, and has been widely welcomed by customers. The wide view business has developed rapidly. In the first half of this year, only Hubei Netcom's "wide view - God's Eye" business has developed more than 500 households. With the rapid development of family information technology, users' demand for family security is becoming stronger and stronger, and the broad horizon will maintain rapid development. China Mobile is also developing mobile MMS monitoring represented by "Handyantong", and 3G video monitoring is also being tested and commercially tested. It is difficult to develop and promote home video surveillance because of the huge data and signal flow relying on the network and the need to deploy home gateways and cameras.
Video monitoring is mainly used in the communities closely connected with families in the industry field, but it is still less used for home monitoring. Under the guidance of the policy of safe cities and safe families, the domestic family monitoring will begin to rise with the continuous improvement of family network environment, the improvement of users' consumption ability, the growth of security awareness, and the increase of independent living families. The integrated video monitoring that integrates limited, wireless access and linkage alarm will become a development trend. Full service operation has arrived. Operators will certainly provide users with wired and wireless diversified technical monitoring means. Through business integration, they will bring users endless monitoring services. Monitoring realizes the discovery and prevention of family safety, and also reflects family care. In addition, efforts should be made to solve the problem of security. Therefore, family monitoring needs to gradually increase some new functions and applications such as linkage alarm and security services, such as emergency help, interaction with public security, medical care, housekeeping, and calling.
