Patzfan 0 Posted April 15, 2015 Hello everyone, new to the forum and hopefully you can help. Running an 8 Channel Dahua 5108h-v2 DVR & HDM2220M 1080p Dahua Cams. Wiring is outdoor Cat5e, and the longest run isnt more that 170 feet (5 Cameras installed). Im using a 12V pover supply box (not the octopus thing). I am using 1 single PAIR for power and 1 for VIDEO from cat5. Baluns are the 5 dollar special. Now onto the problems..... On the longest run Camera i am getting a transparent BLACK BAR that VERY SLOWLY scrolls the screen and on 2 others its there and more feint. also on the longest run camera i am getting a crackling/popping audio when i monitor that channel as the primary one on my dvr, no other cams have audio issues. main concerns are ridding the crackling and cleaning up the pic..... THANKS IN ADVANCE Share this post Link to post Share on other sites
