Now 3G wireless video surveillance has many advantages, such as wide coverage, easy deployment, high reliability, high data throughput, low cost, convenient monitoring, and diverse services. However, the factors such as the limited bandwidth and frequency resources of wireless networks, the high bit error rate of wireless channels, and the fact that wireless transmissions are far more expensive than limited transmissions and public communication systems belonging to shared channel resources have also become the bottleneck in the development of 3G wireless video surveillance technologies. However, relying on 3G networks, it focuses on digital video compression, transmission, storage and playback. It features practical intelligent image analysis and integrates with alarm systems and access control systems on the same platform, thus avoiding the need for traditional monitoring systems. With the problem of cabling network, it is easy to solve the long-distance transmission problem of the signal, and the 3G wireless network video surveillance that achieves multi-point remote monitoring and seamless integration with different monitoring systems is still unmatched by previous generations of video surveillance systems. Domestic 3G monitoring will begin to mature in the mobile 3G wireless broadband network application in 2010, which will be a major trend in the field of video surveillance in the future. 3G wireless video surveillance is a 3G mobile video surveillance device that uses the latest 3G communications technology to meet the needs of home, small business, or specific industry users. It is a simple, easy-to-operate, and cost-effective 3G mobile video surveillance device. Through 3G wireless Internet access 3G network (support China Mobile TD-SCDMA, China Unicom W-CDMA, Telecom CDMA2000), use 3G wireless Internet access port to connect to the camera, just insert the SIM card in the 3G version of the hand-eye through the back end can be used . 3G wireless video surveillance is gradually favored by the market because of its convenience and high performance-price ratio, and it has been used in fire prevention, security guarding, personnel monitoring, remote management and other fields, and is particularly suitable for individuals, families, shops and so on.
In line with the continuous pursuit of technological innovation, HONGWUHUAN have developed a more economical, efficient, simple and reliable crawler type open-air drilling rig in order to adapt to the market development through long-term research and development in drilling machinery products. This product can be widely applied to rock drilling operation in open pit mining, foundation excavation, water conservancy, power station, transportation and national defense construction and other rock drilling operations. It can also drill holes for special purposes, such as anchoring holes, geological pressure measuring holes and drainage holes.

3G wireless video surveillance is based on digital signal processing and combines 3G wireless network transmission to achieve signal exchange, control, video storage, and on-demand playback. Through the establishment of a powerful central service platform, all encoding and decoding devices and videos within the system are realized. Unified management and centralized control of storage devices. For users, only the central service platform is required to log in, browse, and use the entire network monitoring resources.
