I have a strange situation when I installed a new camera. There is a camera with 2 pairs of wire. 1 pair goes to video, 1 pair goes to power. When I install a new camera, I cut the existing old power wire and attach it to the new camera as a video signal. And at the end of the wire I attach it to a balun and to a DVR. I add a new power source to the old and new camera. The problem occurred: 1. At DVR, the video signal(picture) are the same for both camera. 2. Even though I off the power, the new camera still got video signal shown in DVR.

thank you. I replaced the extended wire and it worked fine now.
