4G communication technology: let video surveillance data transmission unimpeded
Video surveillance in the era of large networking, ultra-high-definition video surveillance, massive data transmission and other security applications, can not be separated from the support of high-bandwidth communication technology.
4G refers to the fourth generation of mobile communication technologies, including TD-LTE and FDD-LTE. 4G integrates 3G and WLAN, and can quickly transmit data, high-quality audio video and images. 4G technology supports downlink network bandwidth of 100Mbps~150Mbps, which means users can experience a downlink speed of up to 12.5MB/s~18.75MB/s. If 4G is used in the security industry to monitor video and graphic information transmission, it can not only speed up data. The transmission speed can also meet the requirements of customers for high-definition pictures.
The industry summarizes the advantages of 4G technology compared to previous communication technologies: faster communication speed, wider network spectrum, more flexible communication, higher intelligent performance, smoother compatibility, providing various value-added services and achieving higher quality. Multimedia communication, higher frequency usage, and communication costs are likely to be cheaper.
The impact of 4G network technology on the security industry is mainly reflected in the field of wireless video surveillance. Wireless technology is the key to the speed of information dissemination. For a long time, the performance of wireless network transmission has greatly restricted the development of the security industry. The era of 4G communication technology has opened up, freed from the limitations of wired transmission, and broke the constraints of network transmission performance on the development of security industry.
It can be foreseen that with the continuous deepening of 4G network construction and the continuous improvement of 4G wireless communication technology, 4G will have far-reaching impact on the security industry, especially in high-definition video surveillance, data transmission and data storage. The application of 4G technology will push HD video surveillance to a new stage.
The video business will become the most powerful 4G application, but the security application for 4G network will not only be limited to the "HD video playback" frame, 4G technology in video intelligent identification technology, cluster intercom and video conferencing, Intelligent transportation, vehicle monitoring, home security, smart home and other wireless areas and the construction of smart cities have also played an active role in promoting.
