There are no clear regulations for video cables as there are for USB cables.
For video signals, the optimum length is approximately 10 m when using ordinary pin cords (RCA terminals).
When using coaxial cables (BNC terminals), signal degradation is hardly noticeable even at lengths of 100 to 200 meters.
If you prefer to use RCA terminals, products are available on the market that use RCA terminals for terminals and coaxial cables for cables.
