Video cable refers to the cable that transmits video signals (VIDEOs) and can be used for signal transmission in monitoring systems.
General model: SYV75-X (X represents its insulation outer diameter of 3mm/5mm, the larger the number, the thicker the wire diameter) SYV S-coaxial RF cable, Y-polyethylene, V-polyvinyl chloride 75 represents the characteristic impedance, and the video cable is divided into 75-3 (100 meters) for normal working transmission distance, 75-5 (300 meters) for normal working transmission distance, 75-7 (500-800 meters) for normal working transmission distance, and 75-9 (1000-1500 meters) for normal working transmission distance. The commonly used model is SYV75-5, and the same manufacturer may also provide products at different prices. The specific difference is whether the copper used is pure copper or copper-clad aluminum, or the number of twisted copper cores in the outer shielding layer, such as 96 braided (referring to 96 thin copper cores woven), 128 braided, etc. The more braided, the better the shielding performance. Therefore, this should be noted when purchasing products.
