CCTV surge protector, 4-channel video UTP balun, bassive transmitter, twisted pair, video surge protection, CCTV, twisted pair transformer, DVR, LKT, LKT4, LKT-4, LKT4
LKT-4 is 4-channel device designed to transmission Video signal by 5 category twisted pair at 400m. The device changes impedence from coaxial cable to twisted pair and the signal is transmited in both directions.
The device protects CCTV installation from lightnings, electrostatic overvoltages and vandalism. Electric chargé flowing by the cable is received an transmited to ground by 3 consecutive stages which cause that devices are safe. An electric impuls is transmitted simultaneously from the signal wire and cable shield protecting nearby devices.
LKT-4 has a BNC connector.
