    I am an Electrical Engineer and I am self-employed.I am installing a video surveillance or CCTV system with four cameras and I want to ask you the following: if I am going to build the wiring with UTP Cat5 cable of 4 twisted pairs where I use only one pair for each camera, located in different places and totally opposite distances, and then with a balun at each end to then convert the cable to coaxial which is the one that connects both the camera and the DVR, the question is: Where does the power supply go? Do I have to have an outlet near the camera to power it?
