Security Camera Ground Loop Isolator, BNC Male to Female Coaxial Video Ground Loop Isolator CCTV Balun 1 Pack

Great item

Installed a reverse camera in my high horsepower 95 mustang. Had a ton of magnetic interference with all the wiring in the car especially the fan wiring. Picture with the car not running had slight lines through it but was acceptable. When the car was running it was real static looking and i couldn't bear it. I bought this and coax to rca adapters , electric taped everything a few times and now I have a perfect reverse cam picture with and without the car running!

Potentially, it may work on low resolution camera - 480 or 720 lines. On 4k camera it reduces resolution so much that it seems like 720 lines camera. It does reduce ground loop noise, but reduction of picture quality is so bad so it doesn't matter. Totally worthless on 4k camera.

Ours is an older building with poor grounds in the electrical system. Our sound and video system stretches across several electrical panels and is plagued by ground loop issues. These work great to eliminate those problems.The only thing is that they use that super-thin, rather fragile, and very lossy coax wire. That' why only 4 stars. use the good thick coax and I'd give it 5 stars.Would definitely buy again, though, if I need any more.

Excellent product, installed on a camera feed that went direct to a monitor and it removed the ground loop right away. If you have white scrolling lines on your monitor this will remove that issue.

Had a problematic camera that would sometimes go haywire in terms of color or clarity. It'd look like a horror film intro with the cameras freaking out. Installed this and it fixed it right away. I think one of my camera data wire is too close to an LED ballast but this was much easier fix

Did not pass any video signal in any direction, camera side or dvr side, made no difference. It's a passive device so I should have seen something. No good. Return.

Fixed the issue I had with lines appearing in my backup camera, especially in dark video. Wish there was a version with RCA connectors so I didn’t need adapters.
