Dahua PTZ Series Cameras Sound Routing

[Ratfink11]

Hi everyone,

I have groups of cameras that sit on telescoping masts.

Four Cameras to a Mast/Pole.

I have speakers/mics for these cameras and Im very familiar with setting them up. However....

I would prefer to have the four cameras on the pole share one speaker and microphone rather than having four of everything.

Is there anyway to route the audio channels through the other cameras?

Thanks
