Okay so I'm changing my review because after trying them they don't work. A real balun has a transformer inside that balances the signal. When using it, I received blurry images from surveillance cameras. I use Lorex MPX cameras. It's 2k and they work great with traditional Siamese cable. However, trying to use UTP or even 18G cable gives a blurry picture. Bad product. I do not recommend buying. There's a reason they're so cheap.
