Thank you for the info as i have like a zig zag stripe rolling down on one camera which runs on its own 12v adaptor but on that camera i also have audio built in as standard so do i just put the ground loop filter between dvr and the RCA Plug with the yellow & black camera lead. The dvr is a Samsung SRD1673 and the camera in question is just a composite type 4 wires Red+ Black--- Yellow is video and the blue being the audio and all the negatives are linked shared to the 12v adapter negative which is why im getting a rather anoying loop and audio hum So if you can imagine the yellow and black are connected to the RCA plug and same with the audio RCA Plug. Thanks
