After some help chaps.

I am quoting a site with off site monitored cctv and using a Hik NVR, this isn't my problem.

The problem is I am proposing to put a 5m column 100m from the main building with a wireless bridge to connect to the PTZ. There is not going to be any ground works on site as there is already 240v at the PTZ location, it's in the middle of a farm type area.

Now I need a tanoy on the column. Question is how do I transmit the Audio over the wireless bridge??

I have no problem fitting a 2nd amp at the column but don't want my ARC having two IP addresses for the audio. As the whole site needs one audio source.

Any ideas appreciated.

Does your PTZ have audio?

hik doesn't do broadcast audio like that it needs to use the audio out for most arc's. Its a shame you cant set the cams audio out to be global

Not quoted yet so could quote one with audio if available in hiks range.

you can but that's per channel audio. Ive done it using the audio out and a powered horn, but wont work well with an arc afaik

We have done this on a monitored site and had to tell the arc which cameras had the horns. We had 6 cameras in a rectangle car compound with a horn on every other camera.

agreed but that needs target camera for audio they tend to use the global output

real world stuff not what you ask

We have another site like this and it's a mess as the arc has 3 different Ip addresses for audio in different areas, not the best as most of the time the operators **** it up.

Would need to check this as I think Sentinel may have fixed this
