hello guys! im new here in cctv forums and new also in cctv installation. im working here in saudi arabia and we have a project on this villa. i have this problem on my video output. i am attaching a diagram about the setup and also the solution i had made which i dont think is is right. anyway my main problem actually in only on the video output. i got a wavy image output on my monitor. what i did is i connected a video isolator and it seems to solve the problem for a while, but after two weeks the problem just got worse. the output on the monitor started blinking (on the monitor you can see an image but after a while it will turn off, then on then off repeatedly). so what i did is i remove the isolator then it stops blinking but the wavy image just get worse. im really new in installing cctv cameras and i know there is something wrong with what i did. im really confused guys. your inputs will be greatly appreciated. thank you so much.
*** sorry for my bad english..
