What is the video cable - Kabling Video Cable

Video cable refers to transmit video signals (VIDEO) cable, as a signal transmission monitoring system. General Model: SYV75-X (X on behalf of its insulation outer diameter of 3mm / 5mm, the larger the number the thicker diameter) SYV in S --- coaxial cable, Y --- polyethylene, V --- polychloroprene ethylene. 75 represents the characteristic impedance of the video-wire 75-3 (100 meters) transmission distance-working 75-5 (300 m) to work properly 75-7 transmission distance (500-800 meters) can work in transmission distance 75-9 (1000-1500 meters) transmission distance commonly used model works fine generally SYV75-5, the same manufacturers may also offer products at different price points, this specific difference is the use of copper is copper or copper clad aluminum , or several layers of outer shield twisted copper core, such as: 96 Code (defined by 96 fine copper core braid), 128 series, etc., compiled a few more, shielding performance, the better, so this needs to be attention
