Review on 🔌 High-Performance 10FT White BNC Video Power Cable/Wire for CCTV, Security Camera, DVR, Surveillance System - Plug & Play (White, 10) by Dave Calabro

I have a 12 camera (16 channel) security system that uses BNC cables with 12V power cords like this one. I bought 4 of these cables and 3 new cameras. The fourth cable is intended to replace an already installed damaged cable. I have taken 3 cables out of the box so far only 1 works The picture quality is so bad on the one that works I will be replacing it! There are lines and rainbows on the screen and the video is flickering. Often the video will go blank for a few seconds before turning back on. When I reconnect the same camera with a home made cable, it works great! So I opened 2 more cables to test them and they don't work! Didn't even bother to take the 4th cable out of the box. I am returning all 4. I don't know how Amazon counts these reviews. I just checked the first 6 reviews and 4 of those 6 are ONE STAR! How do they get a 4.4 star rating out of 5 when they get four 1 star ratings out of 6? There will now be FIVE 1 out of 7 star ratings.
