zdyCGTimeBalun HD Cat5 RJ45 to BNC Video Baluns transceiver Passive with Power Connector for 720P 1080P 3MP 4MP 5MP 8MP HD-CVI/TVI/AHD/CVBS/960H Camera(2 Pairs)

Does the job on my cameras to connect via rj45, and the smaller flat cat5e cable was much easier to run.

Great product

Did not work with my system

These are used I. Pairs and work great. Still have not located the old adapter that I purchased 7 years ago that I’d just the rj45 8 pin female to a Bnc and power connector. This works, after switching out some of the old style with a new pair of these. Picture is what I used to use. A pair of these that I bought recently takes the place of this one connector. The pair work great. Sold with 2 sets of 2 in each bag.

I had to replace some older BNC cables that had gone bad. I did not want to run more BNC cabling since I know that I will be switching to an IP system fairly soon. I ran Cat5e cable, terminated the ends and connected these Baluns and it worked plug and play. I think the video/audio quality from these runs are better than the atual BNC cable runs I still have. I bought a couple more so I can switch out the remaining BNC cables. I have a 4K analog DVR with 4K cameras and the image quality is just as good if not better than the older BNC cables. Don't waste your time running BNC cables in 2022. You will regret it when you will want to upgrade to an IP system.

These are well-made but deceptive and wasteful. You get 4 units but can only use 2....why? Simply because only 2 of the power plugs are the correct sex for each system. Hey, plug in the 2 that are correct, and then get a 'converter' to change the other power plugs to be correct, and away you go. You can use 4 out of 4 instead of being wasteful with your resources. The converters are cheap. So why oh why doesn't the manufacturer include 2 converters? I know why.

No issues to date with this product. Easy plug and play. I connected a coaxial camera to my cat6 cable. The length is about 200 feet of cat 6 cable and no issues with the video quality. Time will tell if this will continue to work in the hot attic during the summer. I will update this review if there is any change.

Complete BS doesn't work at all. After looking into it these are incapable of working unless you have unlimited budget. Poe data can not be transmitted across coaxial. Plugged in system could not detect. I know camera works and was powered up to because I even tried alternative power source. Now I got waste time returning this useless hunk of plastic waste of time and money.
