8CH Video+Power transmission devices (SC-MVCP1008) consist of SC-MVTP1001 (1CH Tx.) and SC-MVRP1008 (8CH Rx.). These devices transmit video signal in a long distance with minimizing signal degradation and also supply stable power for camera operation over one coaxial cable. These devices provide not only construction cost reduction, but also high quality video transmission with noise removal function.
