Which is better, analog monitoring system or digital monitoring system

What we usually call ** signal, often refers to the analog ** signal, its recording method is generally analog tape recording, considering the signal attenuation of the video tape itself, with the increase of playback or copying, its image quality will also be irreparably degraded.

Analog monitoring is an analog signal, generally a coaxial cable.

Network monitoring is a digital signal, generally a network cable.

Guardians of social security - surveillance cameras, classification of surveillance: what is the difference between network and simulation.

Network monitoring is for the monitoring and control of computers in the local area network, emulex for the internal computer Internet activities (Internet monitoring) and non-Internet related internal behavior and assets and other process management (intranet monitoring) The rapid development of the Internet, the use of the Internet is becoming more and more common, the network and the Internet not only become the internal communication bridge of the enterprise, but also an important channel for enterprises and external business transactions. Network monitoring products are mainly divided into two types: monitoring software and monitoring hardware.

Analog monitoring is to generate analog signals, convert them into digital signals and store them through capture cards or OVR, or store them in a more primitive way, that is, through media such as video tapes.

Hello, the monitoring system mainly includes:

1. Front-end equipment: cameras (network type, hemispherical type, pinhole type, standard gun type, integrated type, industrial type, etc.).

2. Transmission equipment: optical fiber.

3. Control equipment: DVR or capture card, etc.

Fourth, the display device: the monitor or the splicing screen.

Analog monitoring is to generate analog signals, Xiao Renqing through the capture card or OVR to convert the analog signal into digital signals and store, or through a more primitive way, that is, skillfully grasp through video tape and other media to store it.

Digital monitoring is the elephant head that generates digital information, which can be directly processed.

Relatively speaking, the simulation monitoring is mature, and the resulting ** is clear but not suitable for storage; However, compared with analog monitoring, the signal of digital monitoring has been compressed or processed, and the image is slightly worse, but it is convenient for storage and processing.

However, as digital technology becomes more and more mature, the advantages of digital surveillance are becoming more and more prominent.
