Please help me explain the unexplainable - CAT6 install
DaveInTrinity posted a topic in Installation Help and AccessoriesHi all. I have come here for help. I installed an 8 camera Lorex (Costco) system in my own home. The CAT6 cabling was hung prior to sheet rock in our new build home by the builder's sub. Visually, it looked fine. The result is that I had six of eight cameras go live without a hitch. Two won't work despite every conceivable thing I have tried. Let me explain. First, I am not claiming to be an expert, but I am A+ and Network+ certified and have wired many, many networks over the past 20 years. That being said, I will focus on the two cameras that do not work. If I plug a camera in directly (bypassing the in-house cable runs), the cameras work fine. I have jumpered in a 100ft cable directly from the NVR to the cameras. They both work perfectly this way. So... pretty simply, it's the cable or terminations, right? Here's what I have checked. Cable length (TDR) is about correct (90 feet is the longest cable). Continuity is good. Wire-mapping is correct. POE matches other cables that work, Patch panel and patch cables are good. I have rewired everything on both ends (including wiring the cable onto a different patch panel port) twice now and it always comes up the same. I have checked meter readings from both ends - all match. Meter shows no shorts, no crossovers, no split pairs. I really want to figure this out. It makes absolutely no sense to me. These cameras "should" work, but don't. I have never seen a problem like this that couldn't be diagnosed. Besides, I paid a lot of money to have this place wired and if I can prove the installer did something wrong, I can take it back to him. The roofline on my house makes it darn near impossible to pull new cable without significant expense and labor. What is going on with my cables??? I'm stumped. Please, any insight would be greatly appreciated. Thank you very much. Dave in Trinity
