Best wiring AHD-H based system?

Recommended Posts

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?




2. two passive 4 channel baluns and one Cat5e cable (for power, video, audio)?




Ps: could RS485 be added to the Cat5e cable too?

Hi. A good rg59 and cat5 for video....power ...... Rs485 and audio

Thanks for that!


What does it make better, possibly less video and sound interference problems?
