Analysis of wireless audio and video transmission solutions
The prospect of the wireless video surveillance market in China is very broad. According to statistics, from 2017 to 2020, the video surveillance market will maintain an average annual growth rate of more than 20%, of which the annual growth rate of the high-definition video surveillance market will reach 36%. As an important supplement to the wired transmission of video surveillance, wireless transmission plays a key role in the success of video surveillance projects.
At present, there are many types of wireless video transmission technologies in the market, mainly including 4G network, McWill, 2.4G wireless transmission, and new generation wireless bridge technologies. As a ubiquitous network with wide coverage, 4G network has some features such as low cost and low bandwidth, and is suitable for the deployment of low-bandwidth and low-density video surveillance systems. McWill technology has the characteristics of good coverage, but low bandwidth and high relative cost still restrict its development. At present, there are many video surveillance transmission systems based on 2.4G wireless transmission technology and a new generation of wireless bridge technology deployed in the industry market, each of which has its own advantages.
2.4G wireless transmission technology is widely used and recognized by everyone because of its terminal economy and interoperability. The new generation of wireless bridge technology as a technology dedicated to carrying high-definition video surveillance is also gaining more and more attention.
