CmdrBond 0 Posted June 9, 2015 I note that my Cameras (Hik DS-2CD2132F-IS) and my NVR (Hik DS-7108N-SN/P) all have a screw on the back labelled "Ground". The NVR will be powered by an AC adapter providing DC current, and this in tern will be powering the cameras via PoE. Do I need to ground the equipment? As the NVR is receiving DC input, there is no earth going back to the mains circuit, so I would have to find a sufficient water pipe I presume. What about the cameras? How would I earth them? I can't see grounding them individually is going to be easy. Can I pass the ground back to the NVR? If I were to use STP, could I connect the ground wire to the earth on the back of the camera, and the other end to the earth on the NVR? Looking at the RJ45 socket on the pigtail, I am assuming that it is not designed with STP in mind as it appears to be all plastic. Or should I just not worry and continue to use UTP as planned and ignore the ground screws altogether? Share this post Link to post Share on other sites
