VIMVIP 1080P AHD/HD-CVI/TVI/CVBS Passive HD Video Balun Transmitter 4 Pairs (UTP Up to 350M-600M)

All of them worked perfect with 4k lorex cameras

I bought two sets of these to connect 4 CCTV cameras via a CAT6 cable. Cable is just under 100 feet long, and the installation was a snap and the cameras work perfectly - crystal clear and no buzz or lines.

i got these and the plug in type connectors. these are more work to install but worked so much better. I had a ton of issues with the plug in ones and these havent given me any trouble. some of my runs are 50 feet up to about 175. they are also on a 4mp 1440 cameras.

I have one bad one that doesnt work but others work just fine. Tried contacting customer care but no luck. Cant say its bad but expect only a few will work.

It is a small footprint Dvr. For the price it works well. Gives decent resolution.
