What is the development of video surveillance system?
First, I share you a video about this topic.
The rapid development of image transmission and processing technologies and terminal receiving technologies such as the Internet of Things, 3G, 4G, and 5G networks. It has a significant impact on the network video surveillance system and core technology, and the network video surveillance technology has also undergone innovation.
The network video surveillance system is due to the rich and diverse image information collected, high-resolution pixels, and advanced technology, as well as the advantages and characteristics of convenience and intuitiveness, it has been widely used and popularized in different fields and different occasions.
Code line TV monitoring system, mainly by the front-end monitoring device, transmission device, the rear end of the storage, control and display device, which has five major components. The back-end equipment can be further divided into central control equipment and sub-control equipment. Front and rear equipment configuration more ways. The link between them can be implemented in various ways cable, fiber optics, microwave.
The Video surveillance system has developed past twenty years.
Surveillance from analog to digital surveillance fiery, then in 2012 the emerging network video surveillance, earth-shaking changes have taken place.
Today, IP technology is gradually unifying the world.
We need to re-understand the history of the development of video surveillance systems.
From a technical point of view, the development of video surveillance systems is divided into:
- Close monitoring
In the early stage of video surveillance, video coaxial cables were mainly used to import video images from the front-end monitoring point to the monitoring center, and then play them on the display device.
- Network monitoring
With the help of digital optical transceivers and transmission through multiplexing technology, not only the quality and capacity of video transmission are improved, but also the types of transmission services are enriched.
- IP network monitoring
The continuous maturity of the network virtual matrix also marks that the network video surveillance technology has entered the era of IP network surveillance.
- Optical network monitoring
Use digital technology to digitally encode analog video, but does not require video compression.
