When did the camera appear?
The camera was independently invented by Baird, Philo farnsworth and Vladimir Zvorijin. From the 1980s, when foreign analog monitoring products entered the Chinese mainland market, foreign brands and products almost dominated the world in 20 years. Although some national enterprises have participated in the competition in this industry, they have never had the opportunity to form the mainstream of national brands.
With the rapid development of digital technology, the security field has been fully digitized. Since 2000, the digital security market has developed rapidly, and a number of emerging manufacturers of digital monitoring products have emerged in China, among which DVR manufacturers represented by digital security products have risen rapidly. In just a few years, digital monitoring technology has been applied to all walks of life.
It has made positive contributions to social stability and unity, and at the same time, it has made fundamental changes in the original monitoring market. Analog monitoring products have gradually withdrawn from the market, DVR has been widely used as the main component of digital security engineering, and national brand products have gradually occupied the main market share.
