SYV-75-3 - 7 - 9 TV Video cable
Monitoring video cable
The monitoring video cable is used to connect Security Monitoring head and real terminal (computer or display, etc.) Wire and cable , which is used to transmit the image data taken by the monitoring head. The monitoring video cable is Coaxial cable It is also called coaxial video cable. The letter code is syv, so it is also called syv Cable Or video coaxial cable. The monitoring video line is widely used, and is closely related to our life. We can see the monitoring head in the community, office buildings, street corners and other places. Of course, the monitoring video line is behind us. Therefore, it is the monitoring video cable that provides us with a good security guarantee

Structure Editing
The structure of monitoring video cable from inside to outside is: single core copper → insulating material (PVC, etc.) → braided layer (copper braid, aluminum braid, etc.) → outer sheath (polyethylene, etc.)
The monitoring video cable must have a good shielding effect. The role of the braid layer is here. The shielding layer can well shield out external interference (magnetic field, etc.) and provide a good protection environment for the transmission of core signals.
This structure of coaxial cable makes it have the characteristics of high bandwidth and noise relief. The bandwidth of a coaxial cable depends on the cable length. A 1km cable can achieve a data transmission rate of 1Gb/s~2Gb/s. Longer cables can also be used, but the transmission rate should be reduced or intermediate amplifiers should be used. At present, coaxial cable is largely replaced by optical fiber, but it is still widely used in cable and wireless TV and some local area networks.
