While the rapid growth of public mobile communications and the evolution of mobile communication networks towards 3G, new broadband wireless access technologies such as WIFI, WIMAX, WBMA, and short-range wireless technologies have emerged one after another, and they are gradually maturing. The development of wireless communication industry is diversified. The new pattern of complementary advantages. With the continuous development of communication technologies and the gradual evolution of networks, 3G and various broadband wireless access technologies and short-range wireless technologies are presenting a trend of convergence and development. This will become a broader space for future mobile surveillance applications.
With the maturity of 3G networks, the deepening of triple play, the implementation of M2M strategy, and the deployment of wireless cities, the future carrier-class video surveillance platform will adopt a unified media format and control signaling to support cloud platform deployment and virtual storage. Fully compatible with carrier-class operation network management. Video surveillance will serve as a sub-product package for carriers' unified services. With different business models, it will enter the government, corporate and other industry users and household personal user markets. 3G wireless video surveillance will become a convenient and convenient application that is increasingly known to the industry and the public.
But just like the development of network video surveillance in previous years, the development of 3G technology does not mean that the wireless video surveillance market will be widely used in one or two years. On the contrary, this initial year is precisely the painful period of the wireless surveillance market. Whether from the maturity of technology applications, the improvement of networks (including the construction of a network based on a combination of fixed and wireless technologies), changes in consumer attitudes, changes in business models, etc., the maturity of the entire market will take some time. During this period of time, the market and technology orientation will complete the integration of chip and device manufacturers, monitoring equipment manufacturers, monitoring and application platform developers, distributors and system integrators, terminal customers, and operation and maintenance service providers. 3G wireless video surveillance solution providers will bind their respective security vendors, provide final solutions based on network construction, and continue to optimize existing products and enrich the entire product line; operators will also build and improve their networks. And the use of fierce competition: from the base station's erection, signal coverage and tariff services and other aspects to improve, in order to occupy more markets.
It is worth pointing out that 3G currently uses CDMA technology as the core technology, but its data transmission speed is far below the declared 2 Mbps in advertising, and its actual transmission speed is only about 0.4 Mbps, and it may be even when the network is busy. One-third of the speed is not reached. This situation is only enough to transmit high-quality audio, but it is difficult to transmit high-quality video. In addition, CDMA technology needs more complex equalization and modulation in order to combat multi-path interference, and it is very difficult to implement. In order to promote the development of 3G and the transmission of high-quality video on mobile, people have studied the advantages of OFDM technology in the CDMA system, thereby introducing a combination of CDMA and OFDM technologies, namely CDMA-OFDM technology. In this way, you can overcome the shortcomings of low CDMA actual transmission speed (0.4Mbps), and can adapt to high-speed (>10Mbps) wireless network video communication. Therefore, the combination of CDMA and OFDM transmission technology will greatly promote the development of mobile video surveillance systems, making it the most widely used. Therefore, in the process of advancing from 3G to 4G, the spring of wireless video surveillance is still worth the wait.
The functions of the IP network surveillance cameras operated by Huanyu Feiyang (Beijing) Digital Technology Co., Ltd. can realize the use of 3G mobile phones to remotely access IP cameras through 3G networks. This is also a major aspect of the Huanyu IP network cameras. Advantages, http://. Com
