According to the material, there are two kinds of SYV and SYWV, the physical material structure of the insulation layer is different, SYV is a solid polyethylene cable; SYWV is a high physical foam cable, and the transmission performance of physical foam cable is better than that of polyethylene (S--coaxial cable, Y--polyethylene, V--polyvinyl chloride, W--stabilized polyethylene). According to the impedance, it can be divided into SYV 50-XX, SYV 75-XX, SYV-100 XX...... XX stands for the outer diameter of the insulating layer.

Composite video signal: the general interface is BNC, RCA (lotus head)

75 represents resistance, and the following 3 and 5 represent its insulation outer diameter (3mm/5mm).

Video Cable Points:

75-3 transmission distance of about 200 meters;

75-5 transmission distance of about 500 meters;

75-7 transmission speed distance of about 500--800 meters);

The 75-9 transmission speed distance is about 1000---1500 meters;

The 75-12 transmission distance is about 2000----3500 meters.
