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
