I just purchased a (effin expensive i might add) DVR controller, 16 channel full 25fps per channel recording to 1-8 hard disks
Now from what I understand, an RS485 connector is used (which my DVR has ONE of) to connect to these ptz cameras, but I was wondering what if I wanted 4 or so cameras to have PTZ functionality, how do I connect to them using only one RS485 connector?
I scoured the web for maybe some sort of multiplexer, but nothing helpful comes up.
Can anyone point me in the right direction? It would be incredibly appreciated.
