hazim 0 Posted May 16, 2015 Dear, We have installed many AHD cameras from months, some using UTP with HD baluns, and some with coaxial cables. They are nice but it seems that they are more sensitive to lightnings as we got several cases of problems caused by lightnings in higher rate than normal analog systems. Now we have installed a 16-ch AHD system with 1.3MP Sony IMX238 cameras, using CAT6 cables and HD baluns. Some of the cameras are giving horizontal lines moving vertically as the picture shows. We tried replacing the power supply, but this didn't solve the problem. We've tried many things that could be causing this but nothing helped eliminating or reducing this interference. Note that when all power sources goes off at place of installation after mid night, DVR recordings show no interference in the image during that time. I'll may try other HD baluns for those cameras with interference. Any suggestion is strongly appreciated. Regards, Hazim Share this post Link to post Share on other sites
