bubo 0 Posted May 13, 2017 Having an AHD-H DVR and plenty of RG59, Cat5e and shielded audio cables, I'm wondering what would give the best image quality and sound given a camera distance of 40 meter 1. a separate RG59, a separate shielded audio and a separate power cable to the camera and the microphone? or 2. two passive 4 channel baluns and one Cat5e cable (for power, video, audio)? Ps: could RS485 be added to the Cat5e cable too? Share this post Link to post Share on other sites
