i am new here so if i do this wrong i apoligize.
i have run cat 5 for camera wire 650 foot from our shop to the main building .the picture is good at the source and am using a powered utp for the transmit side and a passive balun on recieve side next to dvr .when i veiw the cameras from my spot monitor they are fine but when i connect to dvr through the passive balun i get major distortion and video loss. all cameras jump and have serious ghosting issues . i have installed ground loop isolators and changed camera wiring to powered balun and changed power supply but nothing working so far . any help would be appreciated, thank you.
