I just ran 250 feet of wire around my house and was very careful with the wire. Go and hook up my camera. it does not work. Switched to a known good camera, still didn't work. then probably where it was necessary to test the cable with an RJ45 tester. Guess what hasn't worked yet. It's not worth my hassle to remove. I should get a refund. 3 hours of my wasted time.
