I'm trying to build a Zoneminder based system to monitor and record activities on my property which includes three different buildings and a number of cameras in those three areas.ideally what I would like to do is connect the cctv cams to a wireless router or hub in each area and feed it back through wifi to my network with zoneminder on it. However.... the cctv cams are coax and the router / hub is cat5. I have seen some adaptors for coax to cat5 but they seem to be designed to go coax-cat5-coax-DVR. I've looked at collector cards as well but really I think the simplest would be coax-cat5-router. Is there a way to do this? I've seen transmitters as well but I can't help feeling there must be a simple way to feed the cctv to cat5 and then the router. Thank-you.
