Kashi 0 Posted December 24, 2022 Hello, I installed three DS-2CE56H0T-I T3ZE cameras on DS-7204HUHI-K1/P using RG59 cable, but none of the cameras are working, can anyone advise if this is compatible or if there is any adjustment I need to do? Share this post Link to post Share on other sites
Nassau Cable 0 Posted December 29, 2022 Hello, the cameras and the DVR are compatible. Maybe you can try with a different cable reference. The impedance of CCTV cameras is 75 ohms. You should use a coax cable that also has an impedance of 75 ohms. Coax cable is also available in 50 ohms and 93 ohms, and those don’t work well in CCTV installations.
