Splitting 485 between two DVR's for PTZ control?

Recommended Posts

I have a situation with two 32 channel DVR's running with loops to provide redundant copies of each other. I now have been asked to provide PTZ control to 6 cameras using Pelco-D. Has anyone here ever just split the wiring and taken it to two DVR's and did it work??? We also have an RS-485 hub that we use for all sorts of stuff, so I have a second option. I am just curious to see if anyone has tried this and what the results were?

I am thinking that I will diodes on one DVR just to keep the traffic flow from getting weird. I am going to try this just as soon as I get done with my current install.... more to follow in a week or so!
