hi, i have a 15 cam instalation wired in cat5 using balum's and where im sending 2 cams down the same cable but on different pairs im gettng slight ghosting note quite rolling my voltage is up at 11.89v dc at the field end does any one know how to stop this???

hi, i have mounted psu's close to dvr in the past even on top of one and not had any problems but if you 230v supply is close to your signal cables you will get noise on your picture especially if runs parralel with them. trev..
